[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 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 effectively solves 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, a relatively obvious shadow corresponding to the lamp arm will appear in the light spot area of ​​the lamp, the light spot quality is disturbed and discounted, and the lighting effect is affected.

[0040] In the present invention, unless otherwise clearly defined, the words "set", "install", "connect" and the like should be understood in a broad sense, for example, they can be directly connected or indirectly connected through an intermediate medium; they can be fixedly connected or detachably connected or integrally formed; they can be mechanically connected; they can be the internal connection of two elements or the interaction relationship between two elements. 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.

[0041] Reference Figures 1 to 11 The embodiment of the utility model is a reflective cup for a non-direct light emitting lamp, which includes a cup body 100. The cup body 100 has a reflective concave surface 110. The reflective concave surface 110 includes a first area 111 and a second area 112. The first area 111 is a bright surface for reflecting light, and the second area 112 is a light absorbing surface. The second area 112 extends from the cup mouth of the cup body 100 to the cup bottom.

[0042] Through the above structure, the reflective concave surface 110 of the reflective cup is set to include a first area 111 and a second area 112, the first area 111 is a bright surface for reflecting light, the second area 112 is a light absorbing surface, and the second area 112 extends from the cup mouth of the reflective cup to the bottom of the cup, so that when the reflective cup is used in a non-direct light emitting lamp, a part of the light emitted by the light source 400 is irradiated to the first area 111 and is reflected to form a light spot, while the light irradiated to the second area 112 is partially or completely absorbed. In the existing reflective cup structure without a light absorbing surface, In the embodiment, the light emitted from the lamp source 400 to the second area 112 is originally reflected and then emitted to the lamp arm 300, so that the outline shadow of the lamp arm 300 becomes obvious on the light spot. However, in this embodiment, the light emitted to the second area 112 eliminates or greatly reduces the reflected light emitted to the lamp arm 300 due to the light absorption effect of the light absorption surface, so that the lamp arm 300 is weakened or will not be illuminated by the reflected light to form a shadow outline, which can greatly improve the quality of the light spot and the lighting effect. The embodiment of the utility model has a simple and compact structure, and is easy to produce and implement with low cost.

[0043] In this embodiment, refer to Figure 1 , Figure 5 ,as well as Fig.10 The second region 112 is in a long strip shape and is a continuous single-piece region.

[0044] It can be understood that when the reflective cup is installed on the lamp and the lamp arm 300 of the lamp is in a strip structure, the long continuous second area 112 and the lamp arm 300 can be set correspondingly. In other words, the axial downward projection of the lamp arm 300 along the cup body 100 at least partially overlaps with the second area 112, so as to further eliminate or greatly reduce the reflected light directed to the lamp arm 300, so that the lamp arm 300 is weakened or will not be illuminated by the reflected light to form a shadow outline, thereby better improving the quality of the light spot and the lighting effect.

[0045] In some embodiments, the specific shape of the second region 112 can be set correspondingly according to the shape of the lamp arm 300. For example, if the lamp arm 300 is C-shaped, the second region 112 can also be designed to be C-shaped.

[0046] In some embodiments, reference Figure 2 The number of second regions 112 is two, and there is a gap between the two second regions 112 .

[0047] It can be understood that when the reflective cup is installed on a lamp and the lamp arm 300 of the lamp is in a strip-shaped structure, the two second areas 112 are respectively arranged corresponding to the contours on both sides of the lamp arm 300, that is, the projections of the contours on both sides of the lamp arm 300 along the axial direction of the cup body 100 fall on the two second areas 112 respectively.

[0048] It should be noted that in the indirect light emitting lamp structure using a reflective cup without a light absorbing surface, the lamp arm 300 is illuminated by the reflected light to form a shadow outline, wherein the edge line between the shadow outline and the bright area of ​​the light spot is actually the outline of the side of the lamp arm 300. Therefore, when the indirect light emitting lamp uses the above-mentioned reflective cup with two light absorbing surfaces, the two second areas 112 of the light absorbing surfaces are respectively arranged to correspond to the outlines on both sides of the lamp arm 300, so as to absorb light to eliminate or greatly reduce the reflected light directed to the outline of the lamp arm 300, thereby eliminating or greatly reducing the contrast between the shadow outline and the bright area of ​​the light spot.

[0049] In this embodiment, refer to Figure 1 and Figure 2 , the bottom of the reflective concave surface 110 is located in the first area 111 .

[0050] It can be understood that when the light source 400 is irradiated toward the reflective concave surface 110, the light reflected from the area close to the bottom of the reflective cup is away from the center of the light spot, forming the peripheral light of the light spot; the light reflected from the area close to the mouth of the reflective cup is close to the center of the light spot, forming the central light of the light spot. It can be seen that the light reflected from the bottom of the reflective concave surface 110 will form the peripheral light of the light spot and will not be reflected on the lamp arm 300. Therefore, the bottom of the reflective concave surface 110 is arranged in the first area 111, that is, the second area 112 which is the light absorbing surface does not need to be arranged at the bottom of the reflective concave surface 110. Therefore, the production cost of the reflective cup can be saved, and the integrity of the light spot cut-off line can be ensured.

[0051] In this embodiment, the light absorbing surface is black.

[0052] In some embodiments, if the light emitted by the lamp source 400 is blue light, the light absorbing surface can be set to orange to absorb blue light; if the light emitted by the lamp source 400 is red light, the light absorbing surface can be set to green to absorb red light.

[0053] In this embodiment, the light absorbing surface is an ink layer, and the ink layer is coated on the second area 112 manually or by equipment.

[0054] In some embodiments, the light absorbing surface is an electroplating layer, and the electroplating layer is attached to the second region 112 through an electroplating process.

[0055] The utility model also provides an indirect light emitting lamp, which comprises a lamp housing 200, a lamp arm 300, a lamp source 400 and the above-mentioned reflective cup for the indirect light emitting lamp.

[0056] Reference Figures 3 to 6 The lamp housing 200 is provided with a accommodating cavity 210 and a light outlet 220 connecting the accommodating cavity 210 with the outside, the lamp arm 300 is provided in the accommodating cavity 210, the light source 400 is provided in the lamp arm 300, and is located on the side of the lamp arm 300 away from the light outlet 220, the cup body 100 is provided in the accommodating cavity 210, the reflective concave surface 110 is arranged opposite to the light source 400, wherein the second area 112 is located below the lamp arm 300, and the downward projection of the lamp arm 300 along the axial direction of the cup body 100 overlaps with the second area 112.

[0057] Through the above structure, the light directed to the second area 112 is eliminated or greatly reduced due to the light absorption effect of the light absorption surface, and the reflected light directed to the lamp arm 300 is thereby weakened or not illuminated by the reflected light to form a shadow outline on the lamp arm 300, thereby greatly improving the quality of the light spot and the lighting effect.

[0058] In some embodiments, a downward projection of the lamp arm 300 along the axial direction of the cup body 100 partially overlaps with the second area 112 .

[0059] In this embodiment, the indirect light emitting lamp is a spotlight.

[0060] In some embodiments, the indirect light emitting lamp is a downlight, specifically referring to 8 to Fig.11 shown.

[0061] In this embodiment, refer to Figure 3 and Figure 5 A light-transmissive dust cover 500 is disposed in the accommodating cavity 210 , and the dust cover 500 is located on a side of the lamp arm 300 close to the light outlet 220 .

[0062] Through the above structure, the dust cover 500 is provided, which covers the lamp arm 300 and the reflective cup, so as to reduce the damage or interference of external dust to the lamp arm 300 and the reflective cup.

[0063] In this embodiment, refer to Figure 3 , Figure 5 as well as Figure 7 The dust cover 500 is a convex lens protruding toward the light outlet 220 .

[0064] Through the above structure, the dust cover 500, which is a convex lens, can reduce the interference of external dust on the lamp arm 300 and the reflector cup, and can refract the reflected light to converge the light emitted from the light outlet 220, so as to further improve the quality of the light spot and the lighting effect. If the dust cover is a plane mirror, when the light reflected by the reflector cup passes through the dust cover, part of the light path is uncontrollable due to refraction and diffuses outward, so that stray light is generated around the light spot, affecting the neatness and lighting effect of the light spot.

[0065] In some embodiments, the dust cover 500 is a flat mirror made of glass.

[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.
