[0001] This utility model relates to the field of lighting technology, and in particular to a lamp. Background Technology

[0002] LED lighting is characterized by low energy consumption, environmental friendliness, and long lifespan, making it the mainstream product in the current lighting industry. Currently, in indoor lighting scenarios, in addition to main lights such as ceiling lights and chandeliers, downlights and spotlights are often added as supplementary lighting. Downlights and spotlights are small in size and compact in structure, typically using COB (Chip On Board) light sources. COB is a packaging method that directly encapsulates multiple LED chips onto a metal-based printed circuit board.

[0003] Currently, the method for mounting and fixing COB light source substrates on lamp holders is through light source brackets. These brackets are secured to the lamp holders with screws, and the COB light source substrate is sandwiched between the lamp holder and the bracket. This screw connection method is cumbersome and inefficient. Furthermore, existing brackets are designed to be compatible with COB light source boards, making it impossible to effectively secure COB light source boards of different sizes. This necessitates the manufacture of brackets of varying sizes, resulting in a certain degree of resource waste. Utility Model Content

[0022] The lamp proposed in this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Figure 1 This is a schematic diagram of the external structure of a lamp fixture according to a preferred embodiment of this application. This embodiment is a track spotlight, including a lamp body 1 and a track connecting seat 8. In other preferred embodiments, the lamp fixture may also be a recessed spotlight, downlight, surface-mounted downlight, etc., and this application does not limit it to these types.

[0024] Figure 2 , Figure 3 They are respectively Figure 1 The exploded and cross-sectional views of the embodiment lighting fixture are shown in the figures. The fixture includes a lamp body 1, a light source 2, an adapter plate 3, and a light source bracket 4. The light source 2 is a COB light source. The lamp body 1 is as follows... Figure 4 As shown, it includes a bottom surface 101 and a side wall 102 extending upward around the bottom surface 101. The end of the side wall facing away from the bottom surface 101 is a light outlet 108. The light source 3 is disposed on the bottom surface 101 of the lamp body 1 and emits light towards the light outlet 108.

[0025] The function of adapter plate 3 is to provide electrical connection for light source 2. For example... Figure 6 As shown, the adapter plate 3 has two flexible arms 301, and conductive contacts 302 are provided on the free ends of the flexible arms 301. During installation, the electrical connection terminals on the light source 2 are soldered to the conductive contacts 302 on the adapter plate 3 via SMT wave soldering. The adapter plate 3 is also provided with an external connection terminal 303. After the power supply wire is soldered to the external connection terminal 303, it is connected to the drive power supply to realize the power supply of the light source 2.

[0026] The light source 2 is fixed to the bottom surface 101 by the light source bracket 4. The light source bracket 4 is as follows: Figure 5 As shown, the device includes a support plate 401. A recessed groove 403 is provided on the side of the support plate 401 facing the light source 2. The cavity formed by the recessed groove 403 is used to accommodate the adapter plate 3. The axial projection shape of the recessed groove 403 matches the adapter plate 3, allowing the adapter plate 3 to be precisely embedded in the recessed groove 403 for positioning. To fix the adapter plate 3, a latch 405 extending towards the inner side of the groove is provided at the opening of the recessed groove 403. In previous designs, a light source accommodating cavity was opened on the light source support to accommodate the light source, resulting in poor versatility of the light source support. When the light source needs to be replaced, a different light source support needs to be custom-made. This application adds an adapter plate 3, which mates with the light source support 4. The size of the adapter plate 3 is fixed, while the position of the conductive contact 302 can be designed according to different light sources 2, thus adapting to more models of COB light sources.

[0027] The bracket plate 401, facing the light source, is also provided with multiple claws 406 extending towards the bottom surface 101. The bottom surface 101 of the lamp body 1 is provided with snap-fit ​​holes 103 that mate with the claws 406. During installation, the welded light source 2 and adapter plate 3 assemblies are snapped into the recessed groove 403 and secured by snap fasteners 405. Then, the light source 2, adapter plate 3, and light source bracket 4 are placed into the lamp body 1 together. The claws 406 pass through the snap-fit ​​holes 103 and snap-fit ​​with the bottom surface 101 of the lamp body 1 to complete the fixation. The light source 2 and adapter plate 3 are stacked and sandwiched between the bottom surface 101 of the lamp body 1 and the bracket plate 401 of the light source bracket 4. To prevent the claws 406 from coming out of the snap-fit ​​holes 103, anti-dislodgement ribs 104 are provided on the side of the snap-fit ​​holes 103 away from the light source 2. The anti-detachment rib 104 protrudes into the locking hole 103 from one side, and at least partially falls into the axial projection of the locking hole 103. The claw 406 includes an arm 4061 and a head 4062. The arm 4061 is elastic, with one end connected to the support plate 401 and the other end being a free end with a head 4062 protruding towards the anti-detachment rib 104. A slot 4063 is provided on the arm 4061. When the claw 406 is inserted into the locking hole 103, the anti-detachment rib 104 pushes the head 4062 away, and the arm 4061 elastically deforms. After the head 4062 has completely passed the anti-detachment rib 104, the arm 4061 springs back to its original position, and the anti-detachment rib 104 locks into the slot 4063 on the arm 4061 to achieve an anti-detachment and self-locking function.

[0028] The embodiment of the lamp includes a two-stage light distribution system. A light distribution element 5 is arranged in the light-emitting direction of the light source 2 to achieve primary light distribution. The light emitted from the light source 2 first passes through the light distribution element 5 and then passes through the reflector 6 for secondary light distribution. The small end of the reflector 6 is connected to the light-emitting surface of the light source 2 and the light distribution element, and the reflector 6 is close to the light outlet 108 of the lamp body 1. In this embodiment, the light distribution element 5 is a lens. In other preferred embodiments, the light distribution element 5 can also be an optical element such as a lens reflector or a light guide. This application does not limit this. There is a gap between the reflector 6 and the light outlet 108. Even if a total internal reflection lens or a lens reflector is used as the light distribution element 5 to reflect most of the light to the light outlet 108, the side of the lens will still be bright, and the bright side will cause light leakage between the reflector 6 and the light outlet 108. To avoid this situation, the light source bracket 4 in this embodiment also includes an isolation wall 402 that surrounds the outer periphery of the bracket plate 401 and extends away from the light source 2. The lens, which serves as the light distribution element 5, has its light-emitting surface covering the upper edge of the isolation wall 402. Besides blocking the lateral light emission from the lens, the isolation wall 402 also acts as a lens support, enabling the lens to be mounted and fixed, thus reducing the number of internal parts and simplifying the structure of the luminaire.

[0029] When the light source bracket 4 is installed into the lamp body 1, it needs to be pressed in forcefully to achieve a snap-fit ​​engagement. To prevent the clip 406 from breaking due to misalignment between the clip and the locking hole 103 during installation, alignment is necessary. Therefore, a positioning rib 105 is provided on the inner side of the side wall 102 of the lamp body 1, and a positioning groove 407 is provided on the outer side of the isolation wall 402. The positioning groove 407 and the positioning rib 105, when engaged, allow for alignment of the clip 406 and the locking hole 103.

[0030] While snap-fit ​​connections are simple to install, they are prone to breakage after disassembly. To reduce the scrap rate, the light source bracket 4 is also equipped with a screw post 408. The screw post 408 has a through threaded hole on its inner side, and the post body of the screw post 408 protrudes towards the light source. Correspondingly, the bottom surface 101 of the lamp body 1 is provided with a screw post cavity 106 to accommodate the screw post 408. A screw passes through the bottom surface 101 and connects with the screw post 408 to fix the light source bracket 4 to the bottom surface 101. This not only reduces the cost of replacing the bracket but also achieves effective contact between the light source 2 and the lamp body 1, resulting in good heat dissipation.

[0031] The description of the preferred embodiments of the present invention above is for illustrative purposes and is not intended to exhaustively describe or limit the present invention to the specific forms disclosed. Obviously, many modifications and variations may be made, which may be apparent to those skilled in the art and should be included within the scope of the present invention as defined by the appended claims.
