OBJECT OF THE INVENTION
[0001] The present invention refers to a lamp that may be indistinctly, a table lamp or
a floor lamp, that is to say, those intended to be placed on a bedside table, an auxiliary
table, etc, or else on the floor.
[0002] The object of the invention is to obtain an autonomous lamp that does not require
connection to the general electrical supply network in order to operate, and that
however, in spite of its performance with batteries, involves a high degree of autonomy
of the same.
BACKGROUND OF THE INVENTION
[0003] As is already known, the basic and typical structure of a table lamp consists of
a foot with greater or lesser height, at the top end of which, a bulb socket for insertion
of the corresponding bulb, is attached together with a support, which is generally
a metallic framework for a lampshade that covers the bulb, facilitating the indirect
falling of the light, generated by the bulb, onto the users.
[0004] Said bulb is fed by the general electric supply network by means of a cord with its
corresponding socket plug, and of a switch, in such a manner, that though said cable
is partially hidden in the inside of the lamp, specifically crossing through the inside
of its foot till it reaches the bulb socket, said cord is mainly visible between the
foot of the lamp and the base of the electrical installation socket of the enclosure,
which poses a problem including two main aspects, on the one hand, said visible cord
has a negative repercussion on the appearance of the enclosure and on the other hand,
the energy feeding system restricts the use of the lamp to the adjacent areas of a
socket base.
DESCRIPTION OF THE INVENTION
[0005] The lamp proposed by the invention solves in a totally satisfactory manner, the previously
described problem, as regards the different aspects commented.
[0006] For this, and more specifically, said lamp is constituted as from a basic body that
may constitute the foot of the lamp when it is a table lamp, or when intended to be
placed on the floor, which may constitute the wall attachment plinth when dealing
with a wall lamp or the ceiling attachment body in the case of a ceiling lamp, which
is the base body on which one or more lamp shades are suspended, with the special
particularity in any of the cases, that the actual lampshade support is made up of
a cylindrical body in the manner of embellisher, that is attached to the base, and
in the interior of which, a printed circuit board is established, with a plurality
of led diodes, that is to say, luminescent diodes which project towards the outside
of the cylindrical body through a series of orifices drilled on them, on their lower
face, and optionally on the top face.
[0007] The reduced energy consumption of these led diodes allows their feeding by means
of batteries with a considerable autonomy and without excessive cost.
[0008] The feeding battery assembly of the led diodes may be integrated inside the cylindrical
body, in which case, said body shall be equipped with a practical cover for replacement
of the batteries, or else these may be housed inside the base body or lamp support,
in which case, it shall in turn be equipped with the complementary access cover for
replacement of said batteries, as well as with an orifice through which the feeding
cord leads from the housing of the batteries to the cylindrical body for feeding the
circuit housed in its interior.
[0009] The feeding of said electrical circuit may be activated in any case by means of a
switch that may be placed on the lower base of the cylindrical head for easy access
to the same, or else on the base body, depending on the arrangement of the batteries,
though said feeding may also be carried out by means of remote control.
[0010] If the batteries are housed in the support base, the cylindrical head shall remain
directly attached to the base, or else, with the interposition of a tubular arm connecting
them and that permits the passage through its interior, of the feeding cords, whilst,
if the batteries are housed inside the head, the lower base of said head shall include
a permanent magnet in central arrangement and forming integral part of the same, with
an additional complementary permanent magnet that finishes off the top end of the
base element, in such a manner, that the assembly constituted by the head and the
lampshade, is couplable and uncouplable from the foot, in an extremely rapid and simple
manner, by means of said magnets. However, the possibility of replacing said magnet
attachment system by another rapid coupling system has been provided, s for example,
a bayonet system or similar.

PREFERRED EMBODIMENT OF THE INVENTION
[0012] In view of the described figures it can be observed how the lamp proposed by the
invention is constituted as any conventional lamp, by means of combining one or more
lampshades (1), of any configuration, preferably of translucid material, with its
corresponding internal framework (2), and with a base element (3), also of any design
or configuration, that constitutes the support base of the lamp on its assembly and
to which lampshades (1) are attached, directly to, or through one or more arms (4)
that form integral part of the base body (3), which, when dealing with a floor or
table lamp, shall constitute a support plinth of the same, as is shown in Figures
1, 3, 4 and 5, when dealing with a wall lamp, shall constitute its means of attachment
to the wall, as is observed in Figure 6 and when dealing with a ceiling lamp, shall
hang from said ceiling by means of a chain (5), as is shown in Figure 7, said base
body (3) being capable of adopting any configuration according to any design lines.
[0013] Therefore, according now, to the invention, between lampshade (1) and the base element
(3), a small cylindrical hollow head (6) is established, on which lower base (7) a
plurality of orifices for installation of respective led diodes (8) are established,
preferably in circumferential alignment, that constitute the light beams of the lamp,
and which are arranged on a printed circuit plate (9) housed inside said head (6).
However, and as has been previously indicated, a second group of led diodes may be
arranged on the top surface of the head (6).
[0014] This printed circuit (9) is fed by a group of cells or batteries (10) in such a manner,
that it is autonomous, that is to say, that it does not require connection to the
general electrical supply network.
[0015] Said batteries (10) may be housed inside the actual head (6) or else in an appropriately
dimensioned housing worked on the base element (3).
[0016] If the batteries (10) are housed inside the actual head (6), the latter shall include
a switch (11) also established on the bottom base of said head, together with the
led diodes (8) for easy accessibility to the same, being provided with a top cover
(12) that is worked in collaboration with a pair of small screws (13) arranged diametrically
opposite, whilst said cover includes in its centre, a neck or threaded stem (14) for
coupling the metallic framework (2) associated to the lampshade (1), specifically
by means of a central bulb socket (15) threaded in correspondence.
[0017] If diodes also exist on the top base, said screws of the cover shall be placed on
the sides of the head so as not to interfere during the installation of said diodes.
[0018] Finally, it has been provided that for the attachment of the head (6) to the top
end (16) of the base element or foot (3), said head (6) shall centrally include a
discoid magnet (17) on its bottom base (7) forming perfect integral part of the same,
and which is complementary with another magnet (18) of equal size and configuration,
that finishes off the top end (16) of base (3), in such a manner, that with a suitable
orientation of said magnets (17) and (18), they constitute a union point that forms
integral part of head (6) to the base (3), which however, is easily dismountable.
In spite of this, said attachment system may be replaced by a bayonet system or any
other system that offers the same services of rapidity and ease during assembly and
disassembly.
[0019] If batteries (10) are housed in the base body (3), as in the lamps shown in Figures
5 to 7, said base body shall have a practical cover, for through access to said batteries
(10), the printed circuit plate (9) being connected to said batteries by means of
a feeding cord (19) that runs through the interior of the base body (3), as in the
case of the arm or arms (5), if they exist. The described structure is complemented
with a switch that may be a conventional manual activation switch, which in the case
of the wall lamp and especially of ceiling lamps, may be materialized in a switch
that is activated by means of a cord or chain of suitable length so as to be accessible
from the floor, or may even be materialized in a remote control, in which case, and
inside said base body, a corresponding receiver circuit of the control waves shall
be established, and which shall be in turn, activator of the led feeding circuit.
