TECHNICAL FIELD OF THE INVENTION
[0001] The invention relates to a luminaire for home use, in particular a luminaire for
work from home, and a method for providing a luminaire.
BACKGROUND OF THE INVENTION
[0002] The market for luminaires may be subdivided into two sections, one professional market
for industrial customers and one residential/living market for private customers.
[0003] Luminaires for the professional market are investment items that meet all requirements
with respect to visual comfort, light distribution and efficiency. Usually, such luminaires
are extremely durable, robust products that are made of high quality and long-time
stable materials and are, thus, accordingly expensive. In addition, such products
subordinate aesthetics, because they have a technical purpose, which means that their
design is rather reserved to unremarkable.
[0004] Luminaires for the residential/living market follow different rules. In this market,
the aesthetics play a very important role next to the functioning of the luminaire.
Normative requirements for a visual task are completely missing. Besides emitting
light, the luminaire particularly has to make a good appearance and perfectly fit
into the homely ambience.
[0005] During the pandemic years between 2020 and 2022, a new application for the lighting
sector has been developed, the lighting for activities in work from home ("home office").
During this period, the requirements for the lighting in privately used spaces for
the first time approached the requirements of professional work in the office. This
does not surprise, because in essence the requirements for activities in the office
are the same as those in work from home. However, because in principle the luminaires
from the professional market are with respect to size, shape and appearance industrial
products, the integration of them into spaces of the private section is very difficult.
Luminaires from the residential/living market, by contrast, have an appealing aesthetic.
However, they do not comprise a professional light technology.
[0006] A further negative aspect results from the new trend of using office spaces. While
before the pandemic the office spaces were divided and delimited based on the respective
activities, nowadays the office spaces are more and more flexibly used. That is, the
traditional open-plan office is displaced more and more in favor of a flexibly designed
and used space arrangement. The traditional office luminaire cannot flexibly react
to this, because it is designed for a specific use.
[0007] A luminaire from the professional market is limited with respect to flexibility regarding
shape, color and surface texture. Usually, such luminaires represent a complex technical
design that, by using integral elements and components, do not allow a flexible isolation.
Thus, such luminaires are at most custom-made with respect to the selection of a specific
color. To this end, a powder-based stove enamel is usually used, which is particularly
suitable for series production in the monochromatic sector.
[0008] It is an objective to overcome one or more of the above-mentioned problems. In particular,
an objective is to combine the excellent lighting characteristics of a luminaire from
the professional market with the requirements of a luminaire for a working environment
at home. Further, an objective is to provide a simple yet professional luminaire that
can meet by its aesthetic the various requirements of a user immediately, and that
can be adapted even after years of its use.
SUMMARY OF THE INVENTION
[0009] The object of the present invention is achieved by the solution provided in the enclosed
independent claims. Advantageous implementations of the present invention are further
defined in the dependent claims.
[0010] According to a first aspect, the invention relates to a luminaire (adapted) for home
use, in particular for work from home, the luminaire comprising: a support; a light
source; a cover arranged on the support such that light emitted by the light source
can pass through the cover; a hood arranged on and releasably attached to the support,
wherein the hood delimits a space in which at least part of the support is arranged;
and a decoration printed on the hood.
[0011] The decoration may comprises dried ink.
[0012] The decoration may comprises a plurality of (small) discrete elements, such as pixels,
that together constitute at least part of the decoration.
[0013] The discrete elements may be obtained by small droplets of liquid ink transferred
onto the hood.
[0014] The decoration may comprise at least 100, preferably at least 1000, more preferably
at least 1,000,000 discrete elements.
[0015] The decoration may comprise different colors. For example, the discrete elements
comprise different colors, respectively.
[0016] The selection of the different colors may be customer-based.
[0017] The decoration may comprise an image, letters and/or other symbols.
[0018] The decoration may provide visible graphics, text, and/or colors.
[0019] The decoration may be provided such that a material of the hood is (substantially)
not modified. For example, the hood comprises a thickness, wherein at least 95%, optionally
at least 98% or at least 99% of the thickness is not affected by the decoration. The
thickness extends from a first surface to a second surface, wherein on the second
surface the decoration is printed. In other words, besides being covered by and connected
to the decoration, the material of the hood (including an optional lacquer layer)
may be substantially not modified or affected due to the decoration.
[0020] In particular, the decoration is not obtained by lacquering and/or powdering (i.e.
the decoration is not powdered). In particular, the decoration is not obtained by
a powder-based coating process such as a stove enamelling process.
[0021] The surface of the hood on which the decoration is arranged may be substantially
free of modifications due to in particular powder-based coating and/or stove processes,
such as stove enameling.
[0022] The decoration may be obtained by a digital inkjet print method and/or a digital
inkjet print device.
[0023] The decoration, in particular the dried ink forming the decoration, may be directly
exposed to an outside of the luminaire. As such, it is suitable for use in interior
spaces and at the same time produced in a cost-effective owing to the omission of
a protection between the decoration and the outside of the luminaire, which outside
does not include harsh conditions.
[0024] In an embodiment, the luminaire is free of any protection layer covering and/or arranged
on the decoration for preventing the decoration from being exposed to an outside of
the luminaire.
[0025] The hood may at least partly surround the support.
[0026] The hood may comprise an outer surface facing an outside of the luminaire (i.e. an
outer surface facing away from the space), wherein the decoration is arranged and
printed on the outer surface.
[0027] The hood may comprises a bottom and one or more side walls extending from the bottom,
wherein the bottom and the one or more side walls delimit the space. For example,
the outer surface is provided by the side wall(s) and/or the bottom.
[0028] The hood may be releasably attached to the support by one or more fastening elements
(such as a screw) and/or by the one or more side walls extending lateral with respect
to the support and/or by a positioning means attached to the support and, optionally,
extending through an opening of the hood. Thereby, the hood may be merely held in
such a way that it cannot move laterally (due to the one or more side walls) and/or
cannot move longitudinally (due to the positioning means) with respect to the support.
[0029] The hood may be formed from a plate and/or sheet, such as a metal plate and/or sheet.
[0030] The hood may be (pre-) lacquered so that the decoration is printed on the lacquered
hood. For example, the plate and/or sheet is lacquered.
[0031] The decoration may be printed on a flat section, i.e. on a section having a continuous
horizontal surface.
[0032] The hood may comprise, or may consist of, metal.
[0033] The hood may be obtained by stamping and/or bending, wherein, optionally, the hood
is a stamp-bent part.
[0034] The hood may comprise at least two parts, wherein, optionally, the at least two parts
are connected to one another without a material bond, such as welding, and/or by a
releasable connection (that can be nondestructively resolved).
[0035] The hood may be at least part of a housing of the luminaire or may provide the housing
of the luminaire.
[0036] The hood may be profiled, e.g. such that it comprises at least one section extending
transversely with respect to another section. The hood may comprise in a cross section
(i.e. in cross-sectional view transverse to a longitudinal axis of the hood) a U-shape
or any other shape such as an H-shape.
[0037] The hood may comprise an opening, in particular provided in its bottom. The opening
may be provided for a back lighting, wherein the cover may be provided for a front
lighting. An optical element, such as a lens, may be at least partially arranged in
the opening.
[0038] In an embodiment, at least the hood has a longitudinal shape, such as a longitudinal
shape such that the length of the hood is at least twice preferably at least five
times the width of the hood.
[0039] The luminaire may comprise a controller arranged on the support.
[0040] The luminaire may be exclusively adapted for use in interior spaces, such as by being
free of any sealing element.
[0041] The cover may be releasably attached to the support.
[0042] At least part of the cover and/or at least part of the support may be imbued (through-dyed).
For example, a specific color may be provided such that it is not only arranged on
a surface of the cover and/or the support but also penetrated into the material of
the cover and/or support.
[0043] The luminaire may have a longitudinal shape, such as a shape having a length and
a width in such a way that the length is at least twice preferably at least five times
the width.
[0044] The support may be arranged completely within the space of the hood.
[0045] In an embodiment, all technical components or devices, which the luminaire comprises,
are arranged on, and/or supported by, the support.
[0046] In an embodiment, the luminaire comprises an attachment element attached to the support
such that the luminaire can be suspended via the attachment element, e.g. by the attachment
element being connectable to an elongate suspending structure, such as a rope or a
cable.
[0047] The attachment element may comprise a first attachment element and a second attachment
element, which may be attached to two end regions of the support, respectively.
[0048] The attachment element may be Y-shaped.
[0049] The hood may comprise an opening through which the attachment element extends. Thus,
the attachment element may aid in releasably attaching the hood to the support. For
example, the attachment element is arranged to position the hood in a defined position
relative to the support. In an embodiment, the attachment element is the positioning
means described above.
[0050] The light source may be arranged on the support.
[0051] The light source may comprise one or more LEDs, optionally arranged on a substrate
such as a circuit board.
[0052] The light source may comprise a first light source for front lighting, e.g. via the
cover, and/or a second light source for backlighting, e.g. via the opening of the
hood and/or the optical element arranged at least partly in this opening.
[0053] The luminaire may comprise an optical element arranged between the light source and
the cover. Thus, the optical element can optically interact with light emitted by
the light source before this light passes through the cover.
[0054] The optical element may comprise a plurality of optical sub-elements, e.g. arranged
along the longitudinal axis of the luminaire.
[0055] The cover may be a shutter and/or may comprise features (such as a wall) for optically
interacting (such as reflecting, fracturing, and/or absorbing) with light emitted
by the light source.
[0056] According to a second aspect, the invention relates to a method for providing a luminaire,
such as a luminaire as described above, wherein the method comprises the steps of:
providing a support; providing a light source and, optionally, arranging the light
source on the support; arranging a cover on the support such that light emitted by
the light source can pass through the cover; printing, by a printing device, a decoration;
and arranging a hood, which delimits a space, on the support such that the hood is
releasably attached to the support and such that at least part of the support is arranged
in the space, wherein the decoration is (digitally) printed on the hood.
[0057] In an embodiment, the step of printing comprises printing the decoration on a material,
such as on a sheet and/or a plate of a material, in particular a metal sheet, wherein
the method comprises the steps of forming the material with the decoration printed
thereon to provide the hood, wherein, optionally, forming comprises bending.
[0058] The step of printing may use only a specific set and/or a specific number of colors,
such as a set of colors with at least two, preferably at least three colors and/or
with not more than five, preferably not more than four colors, wherein, optionally,
the colors comprise cyan, yellow, magenta and black. By combining these colors, up
to 256 million colors can be precisely applied onto the hood.
[0059] The step of printing may use electromagnetic radiation, such as UV radiation, for
providing the decoration. The electromagnetic radiation may be provided in the form
of an energy beam. For example, the electromagnetic radiation may harden and/or dry
a print substance, such as ink, for providing the decoration, and/or may transfer
print substance (e.g. in the form of a droplet), e.g. onto the material provided for
forming the hood or onto the hood, for providing the decoration.
[0060] The step of printing may be void of any material alteration processes, such as stoving
or galvanization, and/or may be void of any use of a gas other than air.
[0061] The step of printing may not include any heating other than a possible heating provided
by using the electromagnetic radiation. For example, the step of printing may not
use any oven.
[0062] The method may comprise the steps of: inputting, via an interface connected via a
network to the printing device, (digital) printing data, wherein, optionally, the
interface comprises a display device, such as a touch screen; and printing, by the
printing device, the decoration based on the printing data. The network may be the
internet.
[0063] The display device may visualize the appearance of a digital model of a luminaire
according to the printing data, in particular at different dimming grades.
[0064] A user device, such as a smartphone, a tablet or a personal computer, may comprise
the interface. The user device may comprise a configuration tool configured for generating
the printing data and/or for adjusting other parameters such as the dimming grades.
[0065] For example, the interface and the printing device are arranged in locations distanced
to one another, such as in a private home (the interface) and in a factory (the printing
device) .
[0066] The method may comprise the step of receiving, e.g. by the printing device, the printing
data, wherein the step of receiving may be before the step of printing.
[0067] The method may comprise a print preparation step before the step of printing, wherein
the print preparation step may comprise the step of receiving the printing data.
[0068] In particular, the following advantages are achieved.
[0069] Providing the decoration with a printing method, in particular a digital printing
method, allows printing a particularly exposed component of the luminaire, namely
the hood, with various decorations (images, letters, symbols, etc.) in accordance
with the specific wishes of the customer.
[0070] By the releasable attachment of the hood to the support, the decoration is also releasably
attached to the support. Thereby, the visual appearance of the luminaire can be easily
modified, e.g. such that the luminaire has a new or other (complex) color appearance
and/or is printed with another decoration, even after years of using the luminaire.
[0071] The hood may be easily detached from the support so that another hood with another
appearance provided by the printed decoration can be attached to the support. The
hood essentially determines the visual appearance of the luminaire, e.g. because it
comprises at least the one or more side walls of the luminaire. Thus, by replacing
the hood by another hood having another appearance due to the printed decoration,
the appearance of the luminaire can be easily modified. In particular, because the
decoration is (digitally) printed onto the hood, this modification can be provided
in accordance with the wish of the customer by using the digital printing method.
The plurality of possible motives, colors and/or labels can be provided by the decoration
in both small and high numbers of quantities. Accordingly, the luminaire can be easily
adapted for its specific location of use, in accordance with the requirements of the
customer with respect to the appearance of the luminaire.
[0072] Therefore, in particular the advantage is achieved that the sophisticated technical
features of a professional office luminaire from the professional market can be easily
combined with the requirements for an aesthetically pleasing/stylish luminaire for
the private market.
[0073] Further, by having the decoration printed on the hood, a particularly efficient production
of the luminaire can be achieved, in particular without much or even no production
waste and/or high energy processes (such as lacquering, burning-in or stoving processes)
for applying the ink onto the hood.
[0074] Further, the decoration being printed on the hood opens the possibility of providing
a luminaire on demand in accordance with the wish of the customer. In particular,
a unique luminaire can be provided in a cost-saving manner. At the same time, however,
it is possible to provide a luminaire in a high quantity in a cost-effective manner.
[0075] In sum, the luminaire and the method make a continuous production process possible
in which luminaires with different appearances provided by the decoration on the hood
can be produced continuously.

[0077] Figs. 1 to 8 show a luminaire 1 according to an embodiment.
[0078] The luminaire 1 is adapted for home use, in particular for work from home, i.e. "home
office". The luminaire 1 may be exclusively adapted for use in interior spaces, such
as by being at least free of any sealing element. The luminaire 1 may have a longitudinal
shape extending along a longitudinal axis. The longitudinal shape may be such that
the length of the luminaire 1 is at least twice, preferably at least five times, more
preferably at least ten times the width of the luminaire 1.
[0079] The luminaire 1 may be a pendant, or suspended, luminaire 1. In particular, the luminaire
1 may be an office lamp, in particular a pendant, or suspended, office lamp.
[0080] The luminaire 1 comprises a support 2. Further, the luminaire 1 comprises a light
source 3, a cover 4 and a hood 5, which may be all - directly or indirectly - arranged
on, and/or supported by, the support 2.
[0081] The support 2 may have a longitudinal shape extending along a longitudinal axis.
The longitudinal shape may be such that the length of the support 2 may be at least
twice, preferably at least five times, more preferably at least ten times the width
of the support 2.
[0082] In an embodiment, all technical components or devices, which the luminaire 1 comprises,
may be arranged on, and/or supported by, the support.
[0083] The support 2 may comprise sections (which may provide fastening and/or holding elements)
on which the light source 3, the cover 4 and the hood 5 may be arranged and/or supported.
The support 2 may comprise or may be made of metal to provide a particularly rigid
structure for receiving the respective components.
[0084] The light source 3 may comprise one or more LEDs 31 that may be arranged on a substrate
32 such as a circuit board. The light source 3 may be releasably attached to the support
2, e.g. by using a fastening connection such as a screw or a snap fit. Alternatively,
the light source 3 may be permanently attached to the support 2, e.g. by using an
adhesive bond. The light source 3 may comprise a first light source 3.1 for front
lighting, e.g. via the cover 4, and/or a second light source 3.2 for backlighting,
i.e. for emitting light along a direction opposite to the light emitted by the first
light source 3.1. The light sources 3.1, 3.2 may be arranged on opposite sides of
the support 2, respectively.
[0085] At least part of the support 2 may be imbued (through-dyed).
[0086] The luminaire 1 may comprise an optical element 7 arranged to optically interact
with light emitted by the light source 3, in particular by the first light source
3.1. Thus, light emitted by the light source 3 (3.1) may first enter the optical element
7, then optically interact with the optical element 7 (e.g. so as to have a different
direction) and finally be coupled out of the optical element 7 in order to enter and
pass through the cover 4. The optical element 7 may comprise a plurality (e.g. at
least two or at least four) of optical sub-elements 71-74 that may be arranged along
the longitudinal axis of the luminaire 1. The optical element 7 may be arranged between
the light source 3 and the cover 4 and/or may be arranged on and/or may be attached
to the support 2, e.g. by using a releasable connection.
[0087] The cover 4 is arranged on the support 2 such that light emitted by the light source
3, in particular by the light source 3.1, can pass through the cover 4. The cover
4 is thus at least in parts transparent for visible light. The cover 4 may comprise
one or more (e.g. curved) walls 41 for interacting with light, such as for reflecting,
fracturing and/or absorbing light.
[0088] The cover 4 may have a longitudinal shape extending along a longitudinal axis. The
longitudinal shape may be such that the length of the cover 4 may be at least twice,
preferably at least five times, more preferably at least ten times the width of the
cover 4.
[0089] The cover 4 may be releasably attached to the support 2, e.g. by using one or more
connection elements (e.g. providing a snap-fit) provided by, and/or integrally formed
with, the support 2 and/or the cover 4.
[0090] At least a part of the cover 4, e.g. the one or more walls 41, may be imbued (through-dyed).
[0091] The hood 5 may be at least part of a housing of the luminaire 1 or may be the housing
of the luminaire 1. The hood 5 may have a longitudinal shape, such as a longitudinal
shape such that the length of the hood 5 is at least twice preferably at least five
times the width of the hood.
[0092] As shown in Fig. 8, the hood 5 delimits a space 51 in which at least part and optionally
all of the support 2 is arranged. The hood 5 may at least partly, or only partly,
surround the support 2. For example, the hood 5 may only partly surround the support
2 such that in a state in which the hood 5 is arranged on, and releasably attached
to, the support 2, at least the light source 3, in particular the light source 3.1,
and/or the cover 4 may be arranged at least partly in the space 51.
[0093] The hood 5 may comprise an outer surface 52 facing an outside of the luminaire 1,
i.e. in a direction away from the space 51. The hood 5 may comprise a bottom 53 and
one or more side walls 54 extending from the bottom 53, wherein the bottom 53 and
the one or more side walls 54 delimit the space 51. The hood 5 may be arranged via
the bottom 53 (in particular via a surface of the bottom 53 facing the space 51) on
the support 2. The one or more side walls 54 may extend laterally with respect to
the support 2. The bottom 53 and/or the one or more side walls 54 may comprise the
outer surface 52. As shown, the hood 5 may comprise in a cross section (such as in
a cross-sectional view transverse to the longitudinal axis of the hood 5) a U-shape.
In other embodiments, the hood 5 may comprise in a cross section any other shape such
as an H-shape. The U-shape may be provided by the bottom 53 and the one or more side
walls 54.
[0094] The hood 5 may comprise an opening 55, e.g. provided in its bottom 53. Via the opening
55, the space 51 may be accessible. The opening 55 may be arranged to provide a backlighting.
For example, at least part of the light emitted by the light source 3.2 may be emitted
through the opening 55. An optical element 8, such as a lens, may be at least partially
arranged in the opening 55, so that at least part of the light emitted through the
opening 55 may be emitted through the optical element 8. The optical element 8 may
be attached to the hood 5, e.g. to the bottom 53.
[0095] The hood 5 may be formed from a plate and/or sheet, such as a metal plate and/or
sheet. The hood 5 may be obtained by stamping and/or bending the plate and/or sheet.
In particular, the hood 5 may be a stamp-bent part. The hood 5 may comprise, or may
consist of, metal.
[0096] The luminaire 1 may comprise one or more attachment elements 9 attached, in particular
releasably attached, to the support 2.
[0097] Each of the one or more attachment elements 9 may be attached to the support 2 by
being inserted into a respective opening 21 of the support 2. For example, each of
the one or more attachment elements 9 may comprise at least one enlarged section 91,
e.g. a ball or a cuboid, which can be inserted into the respective opening 21. Once
inserted into the respective opening 21, the at least one enlarged section 91 may
be moved into a position in order to be attached to the support 2. In this position,
the support 2 may be arranged on and/or supported by at least the enlarged section
91 and/or the at least one enlarged section 91 may be arranged inside of the support
2.
[0098] Via the one or more attachment elements 9, the luminaire 1 can be suspended or hung
up. For example, each of the one or more attachment elements 9 may be connectable
to an (respective) elongate suspending structure 92, such as a rope or cable. The
elongate suspending structure 92 may comprise a first end connectable to the respective
attachment element 9 and a second end connectable to an attachment section such as
a wall, in particular a ceiling.
[0099] As shown in, e.g., Fig. 8, each of the one or more attachment elements 9 may be Y-shaped.
The Y-shape may comprise an I-shaped section connectable to the elongate suspending
structure 92 and a V-shaped section attachable to the support 2. For example, the
V-shaped section comprises the at least one enlarged section 92.
[0100] The hood 5 may comprise one or more openings 56, wherein through each of the one
or more openings 56 a respective attachment element 9 may extend. Each of the one
or more openings 56 may comprise a slit and, optionally, an enlarged opening larger
than the slit. Through the enlarged opening, the respective at least one enlarged
section 91 may be moved through. In an assembled state, a part of the respective attachment
element 9 not comprising the enlarged section may extend through the slit. The attachment
elements 9 may be attached to end sections of the support 2, respectively. The openings
56 may be attached to end sections of the hood 6, respectively.
[0101] The hood 5 is releasably attached to the support 2. This means that the hood 5 can
be detached from the support 2 nondestructively, such as without resolving a material
closure such as a welded connection. For example, a form and/or force fit may be provided
to releasable attach the hood 5 to the support 2. As shown in Fig. 8, one or more
fastening elements 57, such as one or more screws or bolts, may releasably attach
the hood 5 to the support 2. The one or more fastening elements 57 may extend through
the hood 5, such as through the bottom 53, and into the support 2, e.g. into a receiving
section such as an opening with a thread.
[0102] At least the one or more side walls 52 and/or a positioning means, such as the one
or more attachment elements 9 extending through the one or more openings 56 of the
hood 5, may releasably attach the hood 5 to the support 2. The one or more side walls
52 and/or the positioning means may at least effect that the hood 5 is arranged in
a defined position with respect to the support 2. The positioning means may fix the
hood 5 with respect to a longitudinal direction parallel to the longitudinal axis
of the support 2. The one or more side walls 52 may fix the hood 5 with respect to
a direction transverse to the longitudinal axis of the support 2.
[0103] As shown in the figures, the hood 5 may be a single integral part, e.g. formed from
a single sheet or plate. In other embodiments, the hood 5 may also comprise at least
two parts, e.g. arranged along a longitudinal axis of the hood 5. The at least two
parts may be releasably connected to one another, e.g. without a material bond such
as welding.
[0104] As shown in Fig. 8, the luminaire 1 may comprise one or more controllers 9 arranged
on the support 2 and functionally connected to the light source 3, such as to the
first light source 3.1 and the second light source 3.2, respectively. The one or more
controllers 9 may be configured to control the light source 3 according to pulse width
modulation (PWM) and/or to feed the light source 3 with a DC-voltage. The one or more
controllers 9 may be connectable to a power supply, such as means and/or an energy
source, e.g. a battery.
[0105] The luminaire 1 comprises a decoration 11 (digitally) printed on the hood 5. This
means that the decoration 11 adheres to the hood 5 by being printed directly on the
(e.g. lacquered) material of the hood 5. The decoration 11 may be provided such that
a material of the hood 5 is (substantially) not modified. For example, other production
methods, such as lacquering, stove enameling or galvanization, result in that the
material is altered due to chemical and/or physical processes, such as heating or
stoving. Such alterations (e.g., in the form of burn-ins) may be prevented by providing
the decoration 11 on the hood 5 by printing. Accordingly, the surface of the hood
5 on which the decoration 11 is arranged is substantially free of such alterations.
[0106] The decoration 11 is not limited to a particular visual appearance. The decoration
11 may comprise an image, letters and/or symbols. The decoration 11 may provide visible
graphics, text, and/or colors. In particular, the decoration 11 may be customer based.
[0107] The decoration 11 may be arranged on a part of the hood 5 which is particularly well
visible from an outside of the luminaire 1, i.e. from a space in which the luminaire
1 is arranged. For example, the decoration 11 may be arranged on the outer surface
52. The decoration 11 is not limited to a particular size relative to the hood 5.
For example, the decoration 11 may extend along at least 30%, preferably at least
50%, more preferably at least 70% of the length of the hood 5 and/or along at least
30%, preferably at least 50%, more preferably at least 70% of the height of the hood
5. The decoration 11 may be arranged on the bottom 53 and/or on the one or more side
walls 54. The decoration 11 may extend over at least 30%, preferably at least 50%,
more preferably at least 70% of the outer surface 52.
[0108] The decoration 11 may comprise dried and/or hardened (cured) ink. The decoration
11 comprises a plurality of (small) discrete elements, such as pixels, that together
constitute at least part of the decoration 11. For example, the plurality of discrete
elements may comprise at least 1,000, optionally at least 1,000,000 discrete elements.
The decoration 11 may comprise different colors, wherein, optionally, the discrete
elements comprise different colors, respectively. The decoration 11 may be provided
by a digital inkjet print method and/or a digital inkjet print device.
[0109] The decoration 11, in particular the dried ink forming the decoration 11, may be
directly exposed to an outside of the luminaire 1. For example, the luminaire 1 may
be free of any protection layer covering and/or arranged on the decoration 11 for
preventing the decoration 11 from being exposed to the outside of the luminaire 1.
As such, a luminaire 1 is provided that meets the requirements of a luminaire for
home use in a very cost effective manner.
[0110] With reference to Fig. 9, an exemplary embodiment of a method 100 for providing a
luminaire, such as the luminaire 1 described above, is described.
[0111] The method 100 comprises the steps of providing 101 a support 2, providing 102 a
light source 3 and, optionally, arranging the light source 3 on the support 2, and
arranging 103 a cover 4 on the support 2 such that light emitted by the light source
3 can pass through the cover 4.
[0112] The method 100 further comprises the step of printing 104, by a printing device,
a decoration 11. For example, the step of printing 104 comprises printing the decoration
11 on a material 1041, such as on a sheet and/or a plate of a material, in particular
a metal sheet.
[0113] The method 100 optionally comprises the step of forming 105, such as bending, the
material 1041 with the decoration 11 printed thereon. Thereby, a hood 5 may be provided.
[0114] By printing the decoration 11 on the material 1041 and then forming the material
1041 with the decoration 11 printed thereon to provide the hood 5, the hood 5 with
the decoration 11 printed thereon can be provided in a very cost saving manner.
[0115] The method 100 further comprises the step of arranging and releasably attaching 106
a hood 5, such as the hood 5 provided by step 105, which delimits a space 51, on the
support 2 such that at least part of the support 2 is arranged in the space 51, wherein
the decoration 11 is (digitally) printed on the hood 5.
[0116] For example, instead of printing the decoration 11 on the material 1041 and then
forming the material 1041 to provide the hood 5, in another embodiment the decoration
11 may be printed directly onto the hood 5.
[0117] The step of printing 104 may use only a specific set and/or a specific number of
colors, such as a set of colors with at least two, optionally at least three colors
and/or with not more than five, optionally not more than four colors. The colors may
comprise cyan, yellow, magenta and black.
[0118] The step of printing 101 may use, e.g. only, electromagnetic radiation, such as UV
radiation, for providing the decoration. For example, the electromagnetic radiation
may be used i.) for transferring a liquid printing substance, such as liquid ink (e.g.
in the form of a droplet), onto the surface on which the decoration 11 is to be provided,
e.g. onto the material 1041 or directly onto the hood 5, in order to provide the decoration
11 and/or ii.) for hardening (or curing) a print substance (such as ink) in order
to provide the decoration 11. The electromagnetic radiation may be provided in the
form of a beam (energy beam). In particular, the step of printing 101 does not include
any material alteration process, such as a burn-in process or a stoving, and/or does
not include any use of a gas other than air.
[0119] The method 100 may comprise the step of inputting 107, via an interface connected
to the printing device via a network such as the internet, printing data. In the step
of printing 104, the decoration 11 may be printed, by the printing device, based on
the printing data.
[0120] For example, a user device, such as a smartphone, a tablet or a personal computer,
may comprise the interface. Optionally, the interface comprises a display device,
such as a touch screen, on which the appearance of a digital model of the luminaire
1 with the decoration 11 according to the printing data may be visualized, in particular
at different dimming grades. Via the interface, a dimming grade may be selectable.
[0121] All features of all embodiments described, shown and/or claimed herein can be combined
with each other.
[0122] While various embodiments of the present invention have been described above, it
