[0029] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.
[0030] Combine the following Figures 1 to 3 , describing an embodiment of the utility model.
[0031] Please refer to Figure 1 As shown, the reflective cup module of the present application includes a reflective cup 1 and a light source bracket 2, the reflective cup 1 includes a main body 11 and a support member 12 that are connected to each other, the support member 12 is arranged along the outer circumferential surface of the main body 11; the support member 12 is fixed on the light source bracket 2, a heat dissipation channel is formed between the light source bracket 2, the main body 11 and the support member 12, the light source member 3 is arranged on the light source bracket 2, and the light source member 3 is located in the heat dissipation channel.
[0032] Specifically, the support member 12 is arranged around the outside of the body 11 and is distributed circumferentially along the outer circumferential surface of the body 11. The specific shape of the support member 12 is not limited. The support member 12 can be box-shaped, cylindrical, trumpet-shaped or other shapes. When the reflective cup 1 is fixed on the light source bracket 2, the support member 12 contacts with the light source bracket 2, which increases the contact area between the reflective cup 1 and the light source bracket 2, making the fixation of the reflective cup 1 more secure. At the same time, the support member 12 strengthens the body 11 of the reflective cup 1, making the reflective cup 1 not easily deformed. In addition, the support member 12 supports the body 11, so that the body 11 is suspended on the light source bracket 2, and a ventilation gap for air circulation is formed between the body 11 and the light source bracket 2. The ventilation gap is connected with the heat dissipation channel, and the light source 3 and the body 11 in the heat dissipation channel can be ventilated and cooled.
[0033] In one embodiment, Figure 1 As shown, the support member 12 has an extension wall 121, and the extension wall 121 extends toward the direction close to the light source bracket 2. Specifically, the extension wall 121 is fixed on the light source bracket 2, and a heat dissipation space is formed between the extension wall 121 and the light source bracket 2. The thickness of the extension wall 121 is not limited, and the thickness of the extension wall 121 can be set according to the actual needs of the lamp. In this embodiment, the reflective cup 1 adopts a thinner extension wall 121. The thinner extension wall 121 can reduce the space occupied by the extension wall 121 and increase the heat dissipation space between the extension wall 121 and the light source bracket 2, so as to improve the heat dissipation effect of the light source 3 and the reflective cup 1.
[0034] In some optional embodiments, the reflective cup 1 adopts a thicker extension wall 121 . The thicker extension wall 121 increases the contact area between the support member 12 and the light source bracket 2 , and the assembly of the reflective cup 1 is more stable.
[0035] In one embodiment, Figure 2 and Figure 3 As shown, a vent 122 is opened on the extension wall 121, and the vent 122 is connected with the heat dissipation channel. The vent 122 facilitates the heat dissipation channel to communicate with the outside air, thereby improving the air flow and heat dissipation effect in the heat dissipation channel. In this embodiment, the number, shape and size of the vent 122 are not limited. One or more vents 122 can be set. Preferably, the number of vents 122 is not less than two.

Specifically, the light inlet 112 and the light outlet 113 are respectively arranged at two ends of the reflection cavity 111, and the light emitted by the light source component 3 enters the reflection cavity 111 from the light inlet 112, and is then emitted from the light outlet 113 after being reflected by the reflection cavity 111.
[0037] In this embodiment, the main body 11 is spaced apart from the light source 3 , which, on the one hand, facilitates ventilation and heat dissipation between the light source 3 and the main body 11 , and on the other hand, prevents the main body 11 from touching the light source 3 , thereby improving the safety of the operation of the light source 3 .
[0038] In one embodiment, Figure 1 As shown, the support member 12 is arranged in a flared shape from the light outlet 113 toward the light inlet 112 , which can increase the stability of the installation of the support member 12 .

A positioning hole (not shown in the figure) is provided on the light source bracket 2, and the positioning member 13 is inserted into the positioning hole.
[0040] Specifically, when the reflective cup 1 is fixed to the light source bracket 2, the positioning member 13 is inserted into the positioning hole. The positioning member 13 plays a role of positioning and fixing. The specific position of the positioning member 13 is not limited. The positioning member 13 can be set on the support member 12 or on the main body 11. In the present embodiment, the positioning member 13 is set on the main body 11.
[0041] In this embodiment, the connection relationship between the support member 12, the main body 11 and the positioning member 13 is not limited. The support member 12, the main body 11 and the positioning member 13 can be connected by welding, riveting, fastener connection or one-piece molding. Preferably, the support member 12, the main body 11 and the positioning member 13 are connected by one-piece molding. The one-piece molding design makes the connection between the support member 12, the main body 11 and the positioning member 13 more secure and can simplify the installation process between the components.
[0042] In one embodiment, Figure 1 As shown, the light source bracket 2 has a surrounding wall 21 and a bottom plate 23 . The surrounding wall 21 is fixed on the bottom plate 23 . An installation cavity 22 for accommodating the light source component 3 is formed between the surrounding wall 21 and the bottom plate 23 . The support component 12 is fixed on the surrounding wall 21 , and the light source component 3 is located in the installation cavity 22 .
[0043] In this embodiment, the end of the main body 11 close to the light source 3 is the light input end, the extension wall 121 of the support member 12 is fixed on the surrounding wall 21, and a heat dissipation space connected to the heat dissipation channel is enclosed between the extension wall 121, the surrounding wall 21 and the bottom plate 23, and the light input end of the light source 3 and the main body 11 is located in the heat dissipation space.

[0046] Compared with the prior art, the lamp of the present application is provided with a support member 12 on the main body 11 of the reflective cup 1. The support member 12 can strengthen and support the main body 11, so that the installation of the reflective cup 1 is more secure and not easy to deform. At the same time, a heat dissipation channel is provided between the light source bracket 2, the main body 11 and the support member 12, which can ventilate and dissipate heat for the light source part 3 and the reflective cup 1, thereby improving the heat dissipation effect of the reflective cup 1 and the light source part 3.
