Example 1

In the present embodiment, the light source module 12 includes a light source assembly 121 and a light distribution member 122. Further, the light source assembly 121 includes a first light source assembly and a second light source assembly, one of which is disposed at the top wall 111 and the other of which is disposed at the bottom wall 112. The light distribution piece 122 includes a first light distribution piece and a second light distribution piece, which are respectively covered on the first light source assembly and the second light source assembly.

Specifically, the first light source assembly is mounted on the top wall 111, and the first light distributing member 1 is a reflector, specifically a reflective cup. After the light emitted by the first light source component is refracted by the reflecting cup, part of the light is emitted to the light emitting piece 13, part of the light is emitted to the direction of the frame 113, the reflecting piece 14 is arranged on the frame 113 so as to reflect the light emitted to the part, and the light reflected by the reflecting piece 14 is emitted to the direction of the light emitting piece 13. Specifically, the reflecting member 14 is disposed at a side of the frame 113 facing the first light outlet 114, and after the light emitted by the light source assembly 121 is acted by the light distribution member 122, part of the light is directly emitted through the first light outlet 114, and after part of the light is emitted toward the frame 113, the part of the light is reflected by the reflecting member 14 and then emitted from the first light outlet 114. In other embodiments, the reflective member 14 may be a reflective film, i.e., a highly reflective material is sprayed on the bezel 113. And is not limited herein.

The light reflecting cup comprises a small opening covered on the first light source component and a large opening far away from the first light source component, and the small opening can effectively collect light rays emitted by the first light source component. Due to the focusing effect of the small opening on the light rays, the light rays are concentrated before being emitted, so that the utilization rate of the light rays is improved, and the waste of light energy is reduced. The design ensures that the lamp can emit brighter and more concentrated light under the same power, thereby improving the lighting effect. The large opening of the reflecting cup is responsible for reflecting light and increasing the light emitting angle. The design of the large opening enables light rays to be emitted at a wider angle after being reflected, so that the illumination range is enlarged, and the shadow area is reduced. The design makes the lighting effect of the lamp 200 more uniform, and avoids the dead angle of illumination caused by uneven light distribution. The light condensation and reflection effects of the reflecting cup are combined, so that the light distribution and projection effects can be optimized. By adjusting the shape, the material and the surface treatment of the reflecting cup, the light direction can be precisely controlled, so that the light can be emitted according to a preset path and an angle, and different lighting requirements are met. In this embodiment, the end of the reflective cup far away from the first light source assembly is covered with a prism sheet, and the prism sheet is configured to refract a portion of the light emitted from the light emitting element 1212 that is not refracted by the reflective cup, so that the portion of the light is refracted by the prism sheet and then emitted toward the light emitting element 13 or emitted toward the reflecting element 14 on the frame 113, thereby improving the utilization rate of the light emitted from the light source module 12.

The second light source assembly is mounted on the bottom wall 112, and the second light distributing member 2 is a lens. The lens is connected with the inner side of the light source substrate 1211 and covers the light emitting element 1212, the light emitted by the light emitting element 1212 is incident on the light incident surface of the lens, is refracted on the light incident surface, enters the lens under the condition of meeting the Snell's law, is refracted on the light emergent surface, and is emitted from the lens and then passes through the light emitting element 13 to realize uniform emission of the light.

One of the first light source assembly and the second light source assembly is disposed at the top wall 111 or the bottom wall 112, and the other is disposed at the bezel 113.
