[0002] Lamps, whether used for lighting or decoration, have been widely used and have huge market potential.

[0003] Traditional lamps (generally called direct-light lamps) have their light sources located at the bottom of a reflective cup. The light emitted by the light sources directly illuminates the surface of an object to illuminate the object. However, the light emitted by the light sources of the lamps can be easily observed by users and directly enter the human eye, causing users to experience discomfort such as glare, which can easily cause visual fatigue in users.

[0004] For this purpose, another type of lamp (generally referred to as a non-direct light emitting lamp) has appeared, which includes a lamp housing, a reflector cup and a lamp arm arranged on the lamp housing, wherein the light source is arranged on the lamp arm and away from the reflector cup (generally, the light source corresponds to the focal position of the reflective concave surface of the reflector cup), and the light emitted by the light source is first directed to the reflective concave surface, so that the light is reflected by the reflective concave surface and then emitted outward to illuminate the object, which can well solve the problem of glare. However, after research and testing, the inventor found that after the light of the light source of this lamp is reflected by the reflector cup, part of the light will irradiate the lamp arm. Due to the shielding problem of the lamp arm, the light spot area of ​​the lamp will have a relatively obvious contour shadow corresponding to the lamp arm, the light spot quality is disturbed and discounted, and the lighting effect is affected.

Those skilled in the art can reasonably determine the specific meanings of the above words in the present invention in combination with the specific content of the technical solution.

[0038] Reference Figures 1 to 5 The embodiment of the utility model is a non-direct light emitting lamp, which includes a lamp housing 100, a lamp arm 200, a lamp source 300, a reflective cup 400 and a shading member 500.

[0039] The lamp housing 100 is provided with a receiving cavity 110 and a light outlet 120 connecting the receiving cavity 110 with the outside, the lamp arm 200 is provided in the receiving cavity 110, the light source 300 is provided in the lamp arm 200 and is located on a side of the lamp arm 200 away from the light outlet 120, the reflective cup 400 is provided in the receiving cavity 110, and the reflective concave surface 410 of the reflective cup 400 is arranged opposite to the light source 300, and the reflective concave surface 410 includes a first area (not shown in the figure) and a second area The first area can reflect part of the light emitted by the light source 300 so that it is emitted toward the light outlet 120, and the second area can reflect part of the light emitted by the light source 300 so that it is emitted toward the lamp arm 200. The light shielding member 500 is provided on the light source 300. The light shielding member 500 can shield part of the light emitted by the light source 300 toward the second area, so as to prevent or reduce the light reflected by the reflective cup 400 and emitted to the lamp arm 200. The light source 300 includes a circuit board and an LED chip provided on the circuit board. The LED chip is a light emitting portion 310. The light emitting portion 310 can emit light toward the reflective concave surface 410.

[0040] It should be noted that the second area can be an area that can absorb light (specifically, it can be set as a blackened area). When part of the light emitted by the lamp source 300 is directed to the second area, the second area absorbs most of the above light and will reflect the small amount of light that is not absorbed toward the lamp arm 200.

[0041] According to the above structural analysis, when the lamp source 300 emits light toward the reflective concave surface 410 of the reflective cup 400, the first area on the reflective concave surface 410 reflects part of the light and makes it shoot toward the light outlet 120 to form a light spot, and the second area on the reflective concave surface 410 reflects part of the light and makes it shoot toward the lamp arm 200, so that the lamp arm 200 produces an obvious contour shadow on the above light spot. In this regard, the inventor designs a shading member 500, which is arranged on the lamp source 300 to block part of the light emitted by the lamp source 300 toward the second area, thereby eliminating or greatly reducing the light emitted by the lamp source 300 toward the second area, so as to eliminate or greatly reduce the reflected light emitted to the lamp arm 200, so that the lamp arm 200 is weakened or will not be illuminated by the reflected light to form a contour shadow. Therefore, the quality of the light spot and the lighting effect can be well improved. In addition, the structure of the embodiment described in the utility model is simple and compact, and the production and implementation are easy and the cost is low.

[0042] In this embodiment, the indirect light emitting lamp is a downlight.

[0043] In some embodiments, the indirect light emitting lamp is a spotlight, see Figures 6 to 10 shown.

[0044] In some embodiments, the shading member 500 is disposed on the lamp arm 200 to shield a portion of the light emitted by the lamp source 300 toward the second area.

[0045] The reflective concave surface 410 of the reflective cup 400 is arranged opposite to the light source 300. In this embodiment, the light emitting portion 310 of the light source 300 corresponds to the focal position of the reflective concave surface 410. For details, refer to Figure 3 Of course, in order to obtain a special light spot, in some embodiments, the user can set the focal position of the light emitting portion 310 of the light source 300 and the reflective concave surface 410 to be offset.

[0046] In this embodiment, refer to Figures 3 to 5 The lamp arm 200 is a straight cantilever beam structure, the fixed end of the lamp arm 200 is arranged on the cavity wall of the accommodating cavity 110, the light-emitting portion 310 of the lamp source 300 is located at the free end of the lamp arm 200, and the shading member 500 is provided with a shading portion 510 for blocking light, and the shading portion 510 is located on the side of the light-emitting portion 310 close to the fixed end.

[0047] It can be understood that the lamp arm 200 is a cantilever beam structure, one end of the lamp arm 200 is the above-mentioned fixed end, and the other end is the above-mentioned free end.

[0048] According to the above structure, the lamp arm 200 is a straight cantilever beam structure, and the light-emitting portion 310 is located at the free end of the lamp arm 200. It can be seen that the portion between the light-emitting portion 310 and the fixed end is the main portion that blocks and forms the outline shadow of the lamp arm 200 on the light spot. Therefore, most of the light emitted by the light-emitting portion 310 toward the second area must be emitted in a direction biased toward the fixed end, so that the light can be reflected by the second area and emitted toward the above-mentioned portion. Therefore, when the shading portion 510 is provided on the side of the light-emitting portion 310 close to the fixed end, the shading portion 510 can fully block the light emitted by the light-emitting portion 310 along the direction biased toward the fixed end. In other words, it can fully block the light emitted by the light-emitting portion 310 toward the second area. Therefore, it can fully eliminate or greatly reduce the light emitted to the second area, so as to fully eliminate or greatly reduce the reflected light emitted to the lamp arm 200, so that the lamp arm 200 is weakened or will not be irradiated by the reflected light to form an outline shadow.

[0049] Further, in this embodiment, the light shielding portion 510 is provided with a light shielding surface corresponding to the light emitting portion 310, and the light shielding surface is a bright surface, so as to be able to partially or completely reflect the light emitted from the light emitting portion 310 toward the light shielding surface to the first area on the reflective concave surface 410. The bright surface is a smooth reflective surface.

[0050] According to the above structural analysis, the shading portion 510 not only fully blocks the light emitting portion 310 from emitting light toward the second area, but also reflects part or all of the blocked light to the first area on the reflective concave surface 410, so that the light is reflected by the first area and then emitted toward the light outlet 120.

[0051] Through the above structure, on the one hand, the shading portion 510 has the function of blocking light and also has the function of reflecting the blocked light to the first area; on the other hand, the blocked light is reflected by the first area and then emitted toward the light outlet 120, so that the blocked light can be reused to improve the overall light output efficiency of the indirect light emitting lamp and reduce energy waste. In other words, under two indirect light emitting lamps with the same power, the indirect light emitting lamp equipped with the above shading member 500 has higher brightness than the indirect light emitting lamp not equipped with the above shading member 500.

[0052] In some embodiments, only a portion of the light-shielding surface is a bright surface.

[0053] In some embodiments, the bright surface is a reflective surface composed of a plurality of reflective flakes. The plurality of reflective flakes is at least two reflective flakes, and the reflective flake structure can be as follows: Figure 3 The reflective flake structure in the reflective concave surface 410 is shown in FIG.

[0054] In some embodiments, the lamp arm 200 is a C-shaped cantilever beam structure.

[0055] In this embodiment, refer to Figure 4 and Figure 5 The shading portion 510 is an arc-shaped plate structure, and the central angle of the shading portion 510 is β, β=125°.

[0056] It can be understood that all the light emitted by the light-emitting portion 310 forms a conical light beam. Then, through the above structure, the shading portion 510 with an arc-shaped plate structure can be arranged around the axis of the above light beam to be able to more fully block the light emitted by the light-emitting portion 310 along the direction close to the fixed end. In other words, it can more fully block the light emitted by the light-emitting portion 310 toward the second area.

[0057] It is understandable that the setting of the central angle β can be changed according to factors such as the specific usage requirements of the user, the width of the lamp arm 200, etc. Therefore, in some embodiments, β=135°.

[0058] In some embodiments, the shading portion 510 is in a straight plate-shaped structure, and the shading portion 510 is vertically disposed to the straight strip-shaped lamp arm 200 .

[0059] In order to facilitate the subsequent maintenance work on the shading member 500 , the shading member 500 is detachably connected to the light source 300 .

[0060] In some embodiments, the shading member 500 is detachably connected to the lamp arm 200 .

[0061] The shading member 500 is detachably connected to the light source 300. Specifically, the shading member 500, the light source 300 and the lamp arm 200 are stacked in sequence. The lamp arm 200 is provided with a first hole 210, the light source 300 is provided with a second hole 320, and the shading member 500 is provided with a third hole 520. The first hole 210, the second hole 320 and the third hole 520 are penetrated by fasteners (not shown in the figure). Among them, the first hole 210 is a screw hole, the second hole 320 and the third hole 530 are through holes, and the fastener is set as a bolt member. The rod of the fastener is penetrated in the third hole 520, the second hole 320 and the first hole 210 in sequence, and the head of the fastener is located on the side of the shading member 500 away from the light source 300.

[0062] Through the above structure, the connection between the shading member 500, the light source 300 and the lamp arm 200 can be achieved simultaneously only through the connection and cooperation of the third hole 520, the second hole 320, the first hole 210 and the fasteners. Therefore, the effect of saving connecting parts can be achieved, so as to reduce the production cost of the lamp.

[0063] In some embodiments, the first hole 210 , the second hole 320 , and the third hole 520 are all through holes, and the fastener is configured as a bar, and the fastener is tensionedly inserted through the third hole 520 , the second hole 320 , and the first hole 210 in sequence.

[0064] In some embodiments, the shading member 500 is disposed on the light source 300 via an adhesive layer. Of course, if the user wants to dispose the shading member 500 on the lamp arm 200, the shading member 500 can also be disposed on the lamp arm 200 via an adhesive layer.

[0065] In some embodiments, the light source 300 and the light shielding member 500 are integrally formed. Of course, if the user wants to set the light shielding member 500 on the lamp arm 200, the light shielding member 500 can also be integrally formed with the lamp arm 200.

[0066] Of course, the present invention is not limited to the above-mentioned embodiments, and technicians familiar with the field may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications and substitutions are all included in the scope defined by the claims of this application.
