Description

Technical Field

[0001] The invention relates to an indirect lighting fixture, in particular to a reflector cup assembly and an indirect lighting fixture. Background Art

[0002] Indirect lighting refers to a light source that emits light that first goes toward the reflector cup, is reflected by the reflector cup, and then goes outward, making the output light of the lamp more uniform and less dazzling, with a good anti-glare effect.

[0003] The existing non-direct lighting fixtures have a reflective cup inside, which includes a reflective cup, a reflective concave surface inside the reflective cup, a cup wall higher than the reflective concave surface on the reflective cup, and a lamp panel located above the cup wall. The cup wall is used to keep a certain distance between the light source on the lamp panel and the reflective concave surface, so that the light source is higher than the reflective concave surface to meet the optical requirements. The cup wall is integrally formed with the body, and the reflective cup is generally made of silver material to improve the reflectivity in order to achieve good reflection. However, this structure will bring the following problems:

[0004] Since the light source is higher than the reflective concave surface, part of the light emitted by the light source will hit the cup wall (because the light emitted by the light source is not all vertically downward, but diffused at a certain angle, such as 120° toward the reflective cup), and the cup wall will reflect this part of the light. However, the cup wall is not optically designed, making the light reflected by the cup wall uncontrollable, resulting in a lot of uncontrollable stray light on the light spot emitted by the lamp, affecting the quality and aesthetics of the light spot. To solve this problem, it is possible to consider placing a black rubber ring on the cup wall of the reflective cup, using the black rubber ring to block the silver cup wall to avoid reflection at the cup wall. However, the black rubber ring is only placed on the cup wall by interference fit. When the lamp is working, the temperature at the reflective cup position is very high. The black rubber ring is prone to deformation or falling off after long-term use, affecting the service life of the non-direct lamp; and when there are multiple reflective cups on the lamp, the black rubber rings need to be installed one by one, affecting the assembly efficiency. Moreover, the use of the black rubber ring increases the number of spare parts, so that the reflective cup assembly has an additional black rubber ring on the basis of the reflective concave surface and cup wall, which is obviously not conducive to reducing costs.

[0005] Therefore, it is necessary to improve and optimize the existing non-direct lighting fixtures. Summary of the invention

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

[0007] The technical solution adopted by the present invention to solve the technical problem is:

[0008] In a first aspect, an embodiment of the present invention provides a reflective cup assembly, comprising a reflective cup having a reflective concave surface therein, and a light absorbing member, wherein the light absorbing member is arranged on the reflective cup, and a light-transmitting hole is arranged on the light absorbing member, and the light-transmitting hole is arranged around the reflective concave surface, and the hole wall of the light-transmitting hole forms a cup wall higher than the reflective concave surface, the light absorbing member and the reflective cup are arranged separately, and the light absorbing member is fixed to the reflective cup through a connecting structure.

[0009] Optionally, the reflective cup has a single reflective concave surface, and the reflective cup is a single reflective cup; or, the reflective cup has multiple reflective concave surfaces, and the reflective cup is a connected reflective cup, and correspondingly, the light absorbing member has multiple light-transmitting holes to form a connected light absorbing member.

[0017] The present invention has at least one of the following beneficial effects: in the embodiment of the present invention, a light absorbing member is arranged on the reflective cup, a light-transmitting hole is arranged on the light absorbing member, the light-transmitting hole is arranged around the reflective concave surface, the hole wall of the light-transmitting hole forms a cup wall higher than the reflective concave surface, the light absorbing member and the reflective cup are arranged separately, and the light absorbing member is fixed to the reflective cup through a connecting structure, thereby abandoning the structure in which the cup wall and the reflective cup are integrally formed in the prior art, so that the reflective cup and the light absorbing member can be made of two materials, thereby allowing the light absorbing member to use a light-absorbing material, thereby effectively solving the problem of cup wall reflection, because the cup wall does not reflect light or reflects less light, so that the stray light on the light spot emitted by the non-direct lamp can be controlled, and the quality of the light spot is significantly improved; in addition, the embodiment of the present invention also abandons the use of a black rubber ring structure, avoids the aging and falling off problems of the black rubber ring, and reduces the number of parts.

[0018] In particular, for a one-piece reflective cup with multiple reflective concave surfaces, a corresponding one-piece light absorbing component can be selected, and multiple cup walls can be formed by one installation to avoid or reduce the problem of cup wall reflection. Compared with the one-by-one installation of black rubber rings, the assembly efficiency is greatly improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] To make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments described below can be combined with each other arbitrarily without conflict.

[0031] Many different implementations or examples are provided below for implementing the structure of the present invention.

[0032] See also Figure 1-Figure 9 The first aspect of the present invention provides a reflective cup assembly, including a reflective cup 1, wherein the reflective cup 1 has a reflective concave surface 11, and also includes a light absorbing member 2. In some embodiments of the present invention, the light absorbing member 2 is a black plastic member, which has low cost and good light absorption. It can be understood that the light absorbing member 2 is not limited to a plastic member. The light absorbing member 2 is arranged on the reflective cup 1, and a light-transmitting hole 21 is arranged on the light absorbing member 2. The light-transmitting hole 21 is arranged around the reflective concave surface 11, and the hole wall of the light-transmitting hole 21 forms a cup wall 22 higher than the reflective concave surface 11. In this embodiment, the cup wall 22 is a vertical cup wall. The light absorbing member 2 is arranged separately from the reflective cup 1, and the light absorbing member 2 is fixed to the reflective cup 1 through a connecting structure. This structure obviously abandons the structure in the prior art in which the cup wall and the reflective cup are integrally formed, so that the reflective cup and the light absorbing member can be made of two materials, thereby allowing the light absorbing member to be made of light absorbing material, thereby effectively solving the problem of cup wall reflection. Because the cup wall does not reflect light or reflects less light, the stray light on the light spot emitted by the non-direct lamp can be controlled, and the quality of the light spot is significantly improved. In addition, the embodiment of the present invention also abandons the use of a black rubber ring structure, avoids the aging and falling off problems of the black rubber ring, and reduces the number of parts.

[0033] In some embodiments of the present invention, the reflective cup 1 has a single reflective concave surface, and the reflective cup is a single reflective cup; or Figure 1-Figure 5 or Fig. 9 As shown, the reflective cup 1 has a plurality of reflective concave surfaces 11, and the reflective cup is a one-piece reflective cup. Correspondingly, the light absorbing member 2 has a plurality of light-transmitting holes 21 to form a one-piece light absorbing member. The one-piece structure allows a plurality of cup walls to be formed in one installation to avoid or reduce the problem of cup wall reflection. Compared with the one-by-one installation method of black rubber rings, the assembly efficiency is greatly improved.

[0034] In some embodiments of the present invention, the connection structure includes an undercut 23 provided on the light absorbing member 2, and the undercut 23 is buckled on the reflective cup 1. The undercut structure can be used to quickly install the light absorbing member 2 on the reflective cup 1, and the two are reliably connected.

[0035] See Figure 2 As shown, in some embodiments of the present invention, the reflective cup is a one-piece reflective cup, and there are multiple undercuts 23, which are staggered on the light absorbing member 2. This structure allows the light absorbing member 2 to be fixed on the reflective cup 1 through the undercuts 23. The staggered undercuts 23 are beneficial to the force balance of the light absorbing member 2, so that the light-transmitting hole 21 on the light absorbing member 2 can be better aligned with the reflective concave surface 11.

[0036] See Figure 1-Figure 2 As shown, in some embodiments of the present invention, mounting holes 3 are provided on the reflective cup 1 and the light absorbing member 2, and 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, so that the installation of the light source board 4 becomes easy and reliable.

[0037] See Figure 6-Figure 8 As shown, the second aspect of the present invention provides a non-direct lighting fixture, including a heat sink 5, and also including the reflector cup assembly described in any one of the embodiments of the first aspect, wherein the reflector cup assembly is arranged in the heat sink 5. In this embodiment, the non-direct lighting fixture is a spotlight, and it can be understood that the non-direct lighting fixture is not limited to a spotlight, and can also be a table lamp, a floor lamp, a ceiling lamp, etc.

[0038] In the prior art, the reflective cup is installed into the radiator from the front. Specifically, the reflective cup, the lamp board, and the lamp arm board are installed into the radiator from the front in sequence, and then the lamp arm board is covered by a cover plate, so that the other parts of the lamp arm board except the lamp arm are covered by the lamp arm board to improve the aesthetics of the lamp. Finally, the lamp arm board is crimped and fixed by a pressing plate. This structure has at least the following defects: a cover plate is provided on the lamp arm board, which affects the heat dissipation of the lamp; the pressing plate is located on the front of the lamp, which affects and limits the aesthetic design of the front of the lamp. For this purpose, please refer to Figure 6-Figure 8 As shown, in some embodiments of the present invention, the radiator 5 has a front panel 51, the front panel 51 is integrally formed with the radiator 5, and the front panel 51 has a light outlet 52 corresponding to the reflective cup 1, and a lamp arm 53 is arranged in the light outlet 52, and the lamp arm 53 and the radiator 5 are integrally formed of aluminum, and the reflective cup assembly is installed in the radiator 5 from the back; and also includes a back cover 6, and the back cover 6 is connected to the back of the radiator 5. The front panel 51 of this structure is a panel structure integrally formed with the radiator, and the surface is not covered by other components, which greatly improves the heat dissipation and the aesthetics of the lamp.

[0039] See Figure 7and Figure 8 As shown, in some embodiments of the present invention, the back cover 6 is provided with a mounting hole and also includes a pressing plate 7, on which an elastic buckle 71 is provided. The elastic buckle 71 passes through the mounting hole and is buckled with the radiator 5, so that the installation of the lamp becomes simple and reliable.
