DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0026] Hereafter, the technical content of the present invention will be better understood
with reference to preferred embodiments.
[0027] FIG. 1 is a cross-sectional view of a lamp module according to an embodiment of the
present invention. FIG. 2 is a schematic diagram showing a light adjusting element
of the lamp module in FIG. 1. FIG. 3 is a cross-sectional view of the light adjusting
element in FIG. 2. FIG. 4 is an enlarged schematic diagram of a first adjusting structure
in FIG. 1. Please refer to FIGS. 1, 2, 3, and 4. In the present embodiment, a lamp
module 10 is connected to a light source 300. The light source 300, for example, is
an LED (Light Emitting Diode), suitable for emitting at least one light beam. The
lamp module 10 in the embodiment includes a light adjusting element 100, a reflector
200, and a light source 300. Also, the reflector 200, for example, is a reflector.
The reflector 200 in the embodiment includes an incident surface 210 and an output
surface 220. The light source 300 is configured in the incident surface 210.
[0028] It is worth noting that the light adjusting element 100 in the embodiment is disposed
in the reflector 200 for effectively adjusting and controlling the light reflected
to the output surface. Also, the light generated by the lamp module 10 according to
the matched reflector 20 can be projected at an effective angle to form effective
light. For example, the reflector 20 is a reflector of 10° and its effective angle
is 10°, but it is not limited thereto. In this way, as the light intensity within
the effective angle of 10° is more than 300cd, the light beyond 10° will be weakened
and form a halo. The light that forms this halo can be softer because of the design
of the light adjusting element 100. In other words, the lamp module 10 in the embodiment
utilizes the design of the light-adjusting element 100 to generate a better or softer
light projection effect after the light outside the effective angle of 10° is reflected
by the light-adjusting element 100. As long as the user is standing at an angle of
75° and looking back at the lamp module 10, the user will not directly see the light
source 300, such that the high-intensity light emitted by the light source 300 will
not directly entering the user's eyes and cause discomfort. Particularly, for some
special occasions such as performances and exhibitions, the light adjusting element
100 is designed such that the lamp module 10 in the embodiment can provide a more
uniform illumination surface to further improve the visual appearance.
[0029] Specifically, the light adjusting element 100 in the embodiment includes a first
adjusting structure 110, a second adjusting structure 120, and a third adjusting structure
130. Specifically, the second adjusting structure 120 is connected to the first adjusting
structure 110, and the third adjusting structure is connected to the second adjusting
structure 120. In this embodiment, the first adjusting structure 110, the second adjusting
structure 120 and the third adjusting structure 130 are used to control and adjust
the light reflected to the output surface 220. Furthermore, in the present embodiment,
the first adjusting structure 110 is disposed outside of the second adjusting structure
120, and the second adjusting structure 120 is disposed outside of the third adjusting
structure 130. Preferably, the light adjusting element 100 in the embodiment can further
include a fourth adjusting structure 140 for adjusting the light. The fourth adjusting
structure 140 is connected to the third adjusting structure 130 on the inside of the
third adjusting structure 130. In other words, the third adjusting structure 130 is
disposed outside of the fourth adjusting structure 140.
[0030] Particularly, the central structure of the light adjusting element 100 in the embodiment
has a relatively high structural height, which corresponds to the incident surface
210. In contrast, the outside of the light adjusting element 100 has a relatively
low structural height. Thus, in the present embodiment, the distance L3 between the
third adjusting structure 130 and the incident surface 210 is equal to the distance
L4 between the fourth adjusting structure 140 and the incident surface 210, the distance
L3 between the third adjusting structure 130 and the incident surface 210 is less
than the distance L2 between the second adjusting structure 120 and the incident surface
210, and the distance L2 between the second adjusting structure 120 and the incident
surface 210 is less than the distance L1 between the first adjusting structure 110
and the incident surface 210. Furthermore, after the light source 300 emits the light,
the fourth adjusting structure 140, the third adjusting structure 130, the second
adjusting structure 120 and the first adjusting structure 110 adjust and control the
light reflected to the output surface at different configuration positions or height
positions respectively to provide better or softer light projection effects.
[0031] It is worth noting that, in the aforementioned embodiment, although the distance
L3 between the third adjusting structure 130 and the incident surface 210 is equal
to the distance L4 between the fourth adjusting structure 140 and the incident surface
210, in other preferred embodiments, the distance L3 between the third adjusting structure
130 and the incident surface 210 may be greater or less than the distance L4 between
the fourth adjusting structure 140 and the incident surface 210, but the present invention
is not limited thereto.
[0032] Furthermore, the light adjusting element 100 in the embodiment can also include a
first connecting structure 150 and a second connecting element 160. The first connecting
structure 150 is connected to the first adjusting structure 110 configured outside
thereof, and connected to the reflector 200. Furthermore, the light adjusting element
100 is effectively fixed to the reflector 200. Preferably, the first connecting structure
150 has a connecting element 152 and a ring-shaped element 154. The connecting element
152 may be, for example, a rib. The first connecting structure 150 is connected to
the first adjusting structure 110 configured outside thereof, and the first connecting
structure 110 can be connected to the reflector 200 through the connecting element
152 and the ring-shaped element 154 in sequence. In a preferred embodiment, the first
connecting structure 150 is a ring-shaped structure comprising a hook. The hook may
be disposed on the ring-shaped element 154 such that the first connecting structure
150 can be connected with the inside of the reflector 200. Furthermore, a first gap
S1 exists between the ring-shaped element 154 and the first connecting structure 110
for light penetration. Specifically, although the light adjusting element 100 in the
embodiment is fixed to the reflector 200 through the first connecting structure 150,
in other preferred embodiments, the light adjusting element 100 may be directly or
indirectly connected with the reflector 200 by using the first adjusting structure
110, the second adjusting structure 120 or the third adjusting structure 130, but
the present invention is not limited thereto.
[0033] In addition, the second connecting element 160 in the embodiment is connected to
the second adjusting structure 120 configured outside thereof and connected to the
first adjusting structure 110. Specifically, the second connecting element 160 may
be, for example, a rib connected between the first adjusting structure 110 and the
second adjusting structure 120. The first adjusting structure 110 and the second adjusting
structure 120 have a second gap S2 therebetween for light penetration, wherein the
width of the second gap S2 is larger than that of the first gap S1.
[0034] Next, the present invention will be described in detail herein with respect to the
design of the first adjusting structure 110, the second adjusting structure 120, the
third adjusting structure 130, and the fourth adjusting structure 140.
[0035] In this embodiment, the first adjusting structure 110 is provided with a first cut-off
groove G1. The first cut-off groove G1 is a V-shaped groove, and its opening faces
toward the incident surface 210. Furthermore, the first cut-off groove G1 has a first
cut-off wall 112 and a second cut-off wall 114. The first cut-off wall 112 is indirectly
connected to the reflector 200 through the first connecting structure 150, and the
second cut-off wall 114 is connected to the second adjusting structure 120 through
the second connecting element 160. The first cut-off wall 112 may be directly connected
to the reflector 200, and the second cut-off wall 114 may be directly connected to
the second adjusting structure 120, but the present invention is not limited thereto.
[0036] Additionally, in the present embodiment, the distance between the first cut-off wall
112 and the incident surface 210 is less than the distance between the second cut-off
wall 114 and the incident surface 210. In other words, the height of the first cut-off
wall 112 is greater than the height of the second cut-off wall 114. Therefore, a portion
of the light emitted by the light source 300 is limited by the first cut-off wall
112 to avoid forming a halo after a portion of the light reflected by the reflector
200 is emitted at an effective angle. Also, the portion of the light emitted by the
light source 300 is limited by the V-shaped groove between the first cut-off wall
112 and the second cut-off wall 114. Furthermore, a portion of the light emitted by
the light source 300 is reflected repeatedly in the V-shaped groove, and it cannot
easily be re-emitted to the output surface 220 due to structural blockage. Additionally,
the outside of the second cut-off wall 114 will project the incident light at an effective
angle to form effective light. That is, with the first adjusting structure 110 provided
in the embodiment, the first cut-off wall 112 and the first cut-off groove G1 can
be used to shield a portion of the light projected beyond the effective angle. Furthermore,
the incident light projected at the effective angle by the outer edge of the second
cut-off wall 114 can form effective light.
[0037] Furthermore, the second adjusting structure 120 in the embodiment is an inverted
cone structure, and the third adjusting structure 130 is a cone structure. The third
adjusting structure 130 is disposed at the inner edge of the second adjusting structure
120, extends from the inner edge of the second adjusting structure 120 toward the
incident surface 210, and protrudes outside of the second adjusting structure 120.
Specifically, the second adjusting structure 120 has a first opening O1 and a second
opening 02. The distance between the first opening O1 and the incident surface 210
is less than the distance between the second opening 02 and the incident surface 210,
and the diameter R1 of the first opening O1 is larger than the diameter R2 of the
second opening 02. Correspondingly, the third adjusting structure 130 has a third
opening 03 and a fourth opening 04. The distance between the third opening 03 and
the incident surface 210 is less than the distance between the fourth opening 04 and
the incident surface 210, and the diameter R3 of the third opening 03 is less than
the diameter R4 of the fourth opening 04.
[0038] As described above, in the present embodiment, the second adjusting structure 120
has a base 122 that extends from the second opening 02 toward the first opening O1,
and the third adjusting structure 130 is located at the base 122 and protrudes outside
the second adjusting structure 120. In this way, the distance between the third opening
03 and the incident surface 210 is less than the distance between the first opening
O1 and the incident surface 210. In other words, the distance between the third adjusting
structure 130 and the incident surface 210 is less than the distance between the second
adjusting structure 120 and the incident surface 210.
[0039] Particularly, in the present embodiment, a second cut-off groove G2 is designed to
be disposed between the second adjusting structure 120 and the third adjusting structure
130. Since the distance between the third adjusting structure 130 and the incident
surface 210 is less than the distance between the second adjusting structure 120 and
the incident surface 210, in the design of the second cut-off groove G2, the distance
between the wall of the third adjusting structure 130 and the incident surface 210
is less than the distance between the second adjusting structure 120 and the incident
surface 210. In addition, the second adjusting structure 120 allows the surface surrounding
the first opening O1 to be used as a cut-off surface 124 to effectively shield light
that is partially projected at an effective angle.
[0040] So that the light projected to the effective angle will be more uniform, the embodiment
can comprise a light reflective coating on the inner edge of the wall of the third
adjusting structure 130. Similarly, the embodiment may also comprise a light reflective
coating on the outer edge of the wall of the fourth adjusting structure 140. In this
way, the light incident between the third adjusting structure 130 and the fourth adjusting
structure 140 can be projected with a suitable light intensity. Additionally, the
fourth adjusting structure 140 in the embodiment has a third cut-off groove G3 that
is mainly capable of directly shielding a portion of the light directed to the output
surface 220 to prevent visual discomfort and to soften the light projected from the
output surface 220. The third cut-off groove G3 may also be, for example, a V-groove
structure with the opening facing the incident surface 210.
[0041] In a preferred embodiment, the distance L3 between the third adjusting structure
130 and the output surface 220 is less than the distance L4 between the fourth adjusting
structure 140 and the output surface 220. In other words, a portion of the light incident
on the third adjusting structure 130 is not easily affected by the fourth adjusting
structure 140. That is, a portion of the light incident on the third adjusting structure
130 can still be effectively reflected and projected from the output surface 220.
[0042] As described above, the lamp module of the present invention comprises a light adjusting
element set in the reflector to shade or adjust the light by using the first adjusting
structure, the second adjusting structure, the third adjusting structure and the fourth
adjusting structure of the light adjusting element. In this way, the light emitted
from the light source can have a better or softer light projection after passing through
the light adjusting element without any uncomfortable visual experience.

are only illustrative. Those skilled in the art should understand that the structures
and arrangement of the parts can be modified without departing from the scope of the
