In the embodiment, the light source support 31 is annularly arranged inside the frame 10, and one end of the light source support 31 is connected to the first end 11 of the frame 10. Specifically, the first end 11 of the frame 10 is provided with an outwardly protruding mounting portion 111, and the light source support 31 is correspondingly provided with an outwardly protruding connecting portion 311. The connecting portion 311 is lapped on the mounting portion 111, and the base plate 21 is lapped on the connecting portion 311. The base plate 21, the light source support 31 and the frame 10 are fixed by screws through the reserved threaded holes. The side of the light source support 31 facing the frame 10 is recessed with a mounting space 312, and the line light source plate 32 is assembled to the mounting space 312 and emits light towards the second end 12 of the frame 10, i.e. towards the optical assembly 40.

The outer side of each lamp bead on the surface light source plate 22 is covered by a lens, which can mix the light emitted by the lamp beads on the surface light source plate 22, and then the mixed light is emitted through the optical assembly 40 to create a natural light like the blue sky.

[0038] As Figure 3 and Figure 5As shown, the optical assembly 40 comprises a light guide 41 and a diffusion member 42 located in the light emitting direction of the surface light source plate 22 and the linear light source plate 32. The light emitted by the surface light source plate 22 forms straight-down light emission after passing through the diffusion member 42, and the light emitted by the linear light source plate 32 forms lateral light emission after passing through the light guide 41. In the embodiment, the light guide 41 is annularly arranged. A gap is left between the diffusion member 42 and the frame 10, and the light guide 41 is annularly arranged inside the frame and is fitted in the gap. Preferably, the other end of the light source support 31 abuts against the diffusion member 42, and a space is left between the light source support 31 and the inner circumferential wall of the frame 10. The gap, the space and the mounting space 312 are communicated, and the light guide 41 extends into the mounting space 312 from the space, so that the light emitted by the linear light source plate 32 enters the inside of the light guide 41. That is, the light guide 41 is located on the light emitting side of the linear light source plate 32, and the linear light source plate 32 can emit light from the side of the light guide 41 towards the inside of the light guide 41.

The surface of the light guide 41 is provided with a light guide structure 411, and the light inside the light guide 41 is emitted to the diffusion member 42 after passing through the light guide structure 411. The light guide structure 411 is arranged close to the diffusion member 42. In combination with the fact that the light guide structure 411 is arranged on the portion of the surface of the light guide 41 facing the diffusion member 42, the light emitted by the linear light source plate 32 first undergoes total reflection in the light guide 41, so as to achieve the purpose of mixing the light in the light guide 41, and then part of the light is emitted from the inside of the light guide 41 to the diffusion member 42 under the action of the light guide structure 411, and is diffused after passing through the diffusion member 42. Figure 5 The light guide structure 411 is arranged on the portion of the surface of the light guide 41 facing the diffusion member 42. That is, the light guide structure 411 is arranged at the end of the light guide 41 far away from the linear light source plate 32, so that the light emitted by the linear light source plate 32 into the inside of the light guide 41 first undergoes total reflection, so as to achieve the purpose of mixing the light in the light guide 41, and then part of the light is emitted from the inside of the light guide 41 to the diffusion member 42 under the action of the light guide structure 411, and is diffused after passing through the diffusion member 42.

The light guide structure 411 is preferably a plurality of uniformly arranged grooves formed on the outer surface of the light guide 41 by laser, so as to change the reflection surface of the light guide 41, and further change the incident angle of the light, so that the light can be emitted from the inside of the light guide 41. Preferably, since the light inside the light guide 41 is refracted at the light guide structure 411 and causes light loss, a reflective paper can be attached to the outside of the light guide structure 411, so that the refracted light is reflected back into the light guide 41.

[0041] In other optional embodiments, the light guide structure 411 can also be a plurality of protruding and uniformly arranged protrusions, as long as it can change the reflection surface of the light guide 41. Meanwhile, the light guide structure 411 can be adaptively arranged on the inner surface of the light guide 41 or on both the outer surface and the inner surface, which is not limited.

In the present embodiment, the first diffusion portion 421 and the second diffusion portion 422 both comprise a diffusion layer and a transparent layer. Of course, in other optional embodiments, the second diffusion portion 422 can only comprise a diffusion layer. The transparent layer of the first diffusion portion 421 is used to reflect part of the light emitted through the diffusion layer and / or the transparent layer of the second diffusion portion 422 to form a virtual image of the second diffusion portion 422. In order to simulate the window shadow effect formed on the top of the sunroof when one side of the sunroof is illuminated by sunlight.

[0044] The second diffusion portion 422 extends towards the second end 12 of the frame 10 and is connected with the second end 12 of the frame 10. Specifically, the free end of the second diffusion portion 422 is provided with a protruding clamping table 4221. The second end 12 of the frame 10 is provided with an inwardly extending support portion 121, and the support portion 121 is provided with a receiving groove 1211 for accommodating the clamping table 4221 to limit the diffusion member 42, thereby achieving fixed installation of the light guide member 41.

The power module 50 is used to supply power to the surface light source panel 22 and the linear light source panel 32. The control module 60 is installed on the power module 50 and is used to control the light emission of the surface light source panel 22 and the linear light source panel 32. Through the SDL intelligent spectrum technology, the control module 60 can control the surface light source panel 22 to display different light colors according to different scenes when the surface light source panel 22 is lit, and also controls the on-off of the lamp beads on the linear light source panel 32 in different areas, restores the sunlight shining into the window, and the window shadow effect continuously changes with time.

[0046] The bottom plate 21 is further provided with a wire hiding groove 70 and a wire terminal 80 beside the power module 50. The wire light source plate 32 and the area light source plate 22 are connected with the power module 50 through wires. Preferably, the input end of the wire passes through the wire hiding groove 70 and is connected with the output end of the power module 50, so that the wire light source plate 32 and the area light source plate 22 are powered at the same time and the lamp 100 is kept clean and beautiful. The wire terminal 80 is connected with the input end of the power module 50 through a wire.
