Description

Technical Field

[0001] This utility model relates to non-direct lighting fixtures, specifically a reflector assembly and a non-direct lighting fixture. Background Technology

[0002] Non-direct lighting fixtures refer to lighting fixtures where the light emitted by the light source first shines on the reflector, and after being reflected by the reflector, it is emitted outward, making the emitted light of the fixture more uniform and less dazzling, and having a good anti-glare effect.

[0003] Existing indirect lighting fixtures contain a reflector cup with a concave interior. The reflector cup has a wall that extends above this concave surface, and the lamp panel is positioned above this wall. The wall maintains a certain distance between the light source on the lamp panel and the concave surface, ensuring the light source is above the concave surface to meet optical requirements. The wall is integrally formed with the main body, and the reflector cup is typically made of silver material to improve reflectivity. However, this structure presents the following problems:

[0004] Because the light source is positioned above the concave reflector, some of the light emitted by the light source hits the reflector wall (since the light emitted by the light source is not entirely vertically downward, but diffused at a certain angle, such as 120° towards the reflector). The reflector wall reflects this portion of the light, and since the reflector wall is not optically designed, the reflected light is uncontrollable, resulting in many uncontrollable stray lights on the light spot emitted by the lamp, affecting the quality and aesthetics of the light spot. To solve this problem, a black rubber ring could be placed on the reflector wall to block the silver reflector wall and prevent reflections. However, the black rubber ring is simply placed on the reflector wall with an interference fit. When the lamp is working, the temperature at the reflector area is very high, and the black rubber ring is prone to deformation or detachment after prolonged use, affecting the lifespan of the indirect light fixture. Furthermore, when the lamp has multiple reflectors, the black rubber ring needs to be installed one by one, affecting assembly efficiency. Moreover, the use of black rubber rings increases the number of parts, making the reflector cup assembly, which already has a reflective concave surface and cup wall, require an additional black rubber ring, which is obviously not conducive to reducing costs.

[0005] Therefore, it is necessary to improve and optimize existing non-direct lighting fixtures. Utility Model Content

[0006] The present invention aims to solve at least one of the problems of the prior art. To this end, the present invention provides a reflector cup assembly and a non-direct light fixture, which avoids or reduces stray light and helps to improve the quality of the light spot.

[0007] The technical solution adopted by this utility model to solve its technical problem is:

[0008] In a first aspect, this utility model provides a reflector cup assembly, including a reflector cup with a reflective concave surface inside, and a light-absorbing element disposed on the reflector cup. The light-absorbing element has a light-transmitting hole disposed on the light-absorbing element, the light-transmitting hole surrounding the reflective concave surface, and the hole wall forming a cup wall higher than the reflective concave surface. The light-absorbing element is separately disposed from the reflector cup, and the light-absorbing element is fixed to the reflector cup by a connecting structure.

[0009] Optionally, the reflector cup has a single reflective concave surface, and the reflector cup is a single reflector cup; or, the reflector cup has multiple reflective concave surfaces, and the reflector cup is an integrated reflector cup. Correspondingly, the light-absorbing element has multiple light-transmitting holes, forming an integrated light-absorbing element.

[0010] Optionally, the connection structure includes an inverted buckle disposed on the light-absorbing element, the inverted buckle being fastened to the reflector cup.

[0011] Optionally, the reflector is a one-piece reflector, and there are multiple inverted buckles that are staggered on the light-absorbing component.

[0012] Optionally, the light-absorbing element is a black plastic part.

[0013] Optionally, the reflector and the light-absorbing component are provided with mounting holes for mounting the light source board.

[0014] Secondly, this utility model provides a non-direct lighting fixture, including a heat sink and a reflector assembly as described in any of the embodiments of the first aspect above, wherein the reflector assembly is disposed in the heat sink.

[0015] Optionally, the heat sink has a front panel integrally formed with the heat sink, and the front panel has a light outlet corresponding to the reflector cup. A lamp arm is provided in the light outlet, and the reflector cup assembly is installed into the heat sink from the back. It also includes a back cover, which is connected to the back of the heat sink.

[0016] Optionally, the rear cover is provided with mounting holes and also includes a pressure plate. The pressure plate is provided with an elastic buckle, which passes through the mounting holes and engages with the radiator.

[0017] This utility model has at least one of the following beneficial effects: In this embodiment, a light-absorbing component is provided on the reflector cup, and a light-transmitting hole is provided on the light-absorbing component. The light-transmitting hole surrounds the reflective concave surface, and the hole wall forms a cup wall higher than the reflective concave surface. The light-absorbing component and the reflector cup are separately arranged, and the light-absorbing component is fixed to the reflector cup by a connecting structure. This eliminates the existing structure where the cup wall and the reflector cup are integrally formed, allowing the reflector cup and the light-absorbing component to be made of two different materials. This allows the light-absorbing component to use a light-absorbing material, thereby effectively solving the problem of cup wall reflection. Because the cup wall is non-reflective or reflects very little light, stray light on the light spot emitted by non-direct light fixtures can be controlled, and the quality of the light spot is significantly improved. Furthermore, this utility model also eliminates the use of a black rubber ring structure, avoiding the aging and detachment problems of the black rubber ring and reducing the number of parts.

[0018] In particular, for integrated reflective cups with multiple reflective concave surfaces, corresponding integrated light-absorbing components can be selected. Multiple cup walls can be formed in one installation to avoid or reduce cup wall reflection problems. Compared with the method of installing black rubber rings one by one, the assembly efficiency is greatly improved. Attached Figure Description

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described below can be arbitrarily combined with each other.

[0031] The following provides many different implementation methods or examples for realizing the structure of this utility model.

[0032] See Figures 1-9 The first aspect of this utility model provides a reflector cup assembly, including a reflector cup 1 with a reflective concave surface 11 and a light-absorbing component 2. In some embodiments of this utility model, the light-absorbing component 2 is a black plastic component, which is low in cost and has good light absorption. It is understood that the light-absorbing component 2 is not limited to plastic components. The light-absorbing component 2 is disposed on the reflector cup 1 and has a light-transmitting hole 21. The light-transmitting hole 21 surrounds the reflective concave surface 11, and the hole wall of the light-transmitting hole 21 forms a cup wall 22 that is higher than the reflective concave surface 11. In this embodiment, the cup wall 22 is a vertical cup wall. The light-absorbing component 2 and the reflector cup 1 are separately disposed, and the light-absorbing component 2 is fixed to the reflector cup 1 by a connecting structure. This structure clearly abandons the existing technology's one-piece molding of the cup wall and reflector cup, allowing the reflector cup and light-absorbing component to be made of two different materials. This allows the light-absorbing component to use a light-absorbing material, thereby effectively solving the problem of cup wall reflection. Because the cup wall is non-reflective or reflects very little light, stray light on the light spot emitted by non-direct light fixtures can be controlled, and the quality of the light spot is significantly improved. In addition, this embodiment of the utility model also abandons the use of the black rubber ring structure, avoiding the aging and falling off problems of the black rubber ring and reducing the number of parts.

[0033] In some embodiments of this utility model, the reflector cup 1 has a single reflective concave surface, and the reflector cup is a single reflector cup; or, as... Figures 1-5 or Figure 9As shown, the reflector cup 1 has multiple reflective concave surfaces 11, and the reflector cup is a one-piece reflector cup. Correspondingly, the light-absorbing component 2 has multiple light-transmitting holes 21, forming a one-piece light-absorbing component. This one-piece structure allows multiple cup walls to be formed in one installation to avoid or reduce cup wall reflection problems. Compared with the individual installation method of black rubber rings, it greatly improves assembly efficiency.

[0034] In some embodiments of this utility model, the connecting structure includes an inverted buckle 23 disposed on the light-absorbing component 2. The inverted buckle 23 is fastened to the reflector cup 1. Using the inverted buckle structure, the light-absorbing component 2 can be quickly installed on the reflector cup 1, and the connection between the two is reliable.

[0035] See details Figure 2 As shown, in some embodiments of this utility model, the reflector cup is a one-piece reflector cup, and there are multiple inverted buckles 23, which are staggered on the light-absorbing component 2. This structure allows the light-absorbing component 2 to be fixed on the reflector cup 1 by the inverted buckles 23. The staggered inverted buckles 23 are conducive to the force balance of the light-absorbing component 2, so that the light-transmitting hole 21 on the light-absorbing component 2 can be better aligned with the reflective concave surface 11.

[0036] See details Figures 1-2 As shown, in some embodiments of this utility model, the reflector cup 1 and the light absorber 2 are provided with mounting holes 3. The mounting holes 3 are used to install the light source board 4. The light source board 4 can be locked by passing screws through the mounting holes 3, making the installation of the light source board 4 easy and reliable.

[0037] See details Figures 6-8 As shown, a second aspect of this utility model provides a non-direct-light lamp, including a heat sink 5 and a reflector assembly as described in any of the first aspects of the present invention, wherein the reflector assembly is disposed in the heat sink 5. In this embodiment, the non-direct-light lamp is a spotlight. It is understood that the non-direct-light lamp is not limited to spotlights, but can also be a table lamp, floor lamp, ceiling lamp, etc.

[0038] In existing technology, the reflector cup is installed into the heat sink from the front. Specifically, the reflector cup, lamp panel, and lamp arm plate are installed into the heat sink sequentially from the front. Then, a cover plate is used to cover the lamp arm plate, obscuring all parts of the lamp arm plate except the lamp arm itself, thus improving the aesthetics of the lamp. Finally, a pressure plate is used to press and fix the lamp arm plate. This structure has at least the following drawbacks: the cover plate on the lamp arm plate affects the heat dissipation of the lamp; the pressure plate is located on the front of the lamp, affecting and limiting the aesthetic design of the front of the lamp. Therefore, see [link to relevant documentation]. Figures 6-8As shown, in some embodiments of this utility model, the heat sink 5 has a front panel 51, which is integrally formed with the heat sink 5. The front panel 51 has a light outlet 52 corresponding to the reflector cup 1, and a lamp arm 53 is disposed in the light outlet 52. The lamp arm 53 is integrally formed with the heat sink 5 and made of aluminum material. The reflector cup assembly is installed into the heat sink 5 from the back. It also includes a rear cover 6, which is connected to the back of the heat sink 5. This structure has a front panel 51 that is integrally formed with the heat sink, and the surface is not covered by other parts, which greatly improves heat dissipation and also improves the aesthetics of the lamp.

[0039] See details Figure 7 and Figure 8 As shown, in some embodiments of this utility model, the rear cover 6 is provided with mounting holes and also includes a pressure plate 7. The pressure plate 7 is provided with an elastic buckle 71. The elastic buckle 71 passes through the mounting holes and is fastened to the heat sink 5, making the installation of the lamp simple and reliable.

[0040] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
