[0056] Different from the prior art, the present invention improves the design of the light source housing 1 and the surface light source rear cover 2. Through the snap-fit between the two, after the surface light source housing 1 and the surface light source rear cover 2 are assembled and installed, the gap between the two can accommodate the light-emitting component, so that the light-emitting component can be clamped by the surface light source housing 1 and the surface light source rear cover 2, and there is no need for bonding between the light-emitting component, the surface light source housing 1 and the surface light source rear cover 2.

[0057] In some embodiments of the present utility model, the surface light source housing 1 includes a bottom surface and a side surface located on the circumference of the bottom surface. The surface light source housing 1 forms a notch groove 102, and the notch groove 102 is an opening formed on the bottom surface of the surface light source housing 1.

[0058] The structure of the light-emitting component is similar to that of the existing surface light source products, and includes a diffusion layer panel 3, a light guide layer panel 4 and a reflection layer panel 5. The diffusion layer panel 3, the light guide layer panel 4 and the reflection layer panel 5 are all arranged in the notch groove 102, and in the direction from the light source housing 1 to the surface light source rear cover 2, the diffusion layer panel 3, the light guide layer panel 4 and the reflection layer panel 5 are arranged in sequence. That is, the diffusion layer panel 3 is located at the bottom of the notch groove 102; the light guide layer panel 4 is located on the side closer to the surface light source rear cover 2 relative to the diffusion layer panel 1; the reflection layer panel 5 is located on the side closer to the surface light source rear cover 2 relative to the light guide layer panel 4. There is no need for bonding between the diffusion layer panel 3, the light guide layer panel 4 and the reflection layer panel 5.

[0059] The light-emitting component further includes an LED light bar 6, which is also arranged in the notch groove 101 and is located on the side surface in the thickness direction of the diffusion layer panel 3, the light guide layer panel 4 and the reflection layer panel 5. There is also no need for bonding between the LED light bar 6 and the diffusion layer panel 3, the light guide layer panel 4 and the reflection layer panel 5.

[0060] In some embodiments of the present utility model, the notch groove 101 includes a groove bottom surface 1011 and a groove side wall 1012.

[0061] In addition to the groove side wall 1012, the surface light source housing 1 further includes an outer side wall 105, and the outer side wall 105 is located outside the groove side wall 1012, and there is a gap between the two. The gap part forms a weight reduction groove 106, which can reduce the overall weight of the surface light source housing 1.

[0062] In some embodiments of the present utility model, the notch groove 101, the diffusion panel 2, the light guide panel 3, and the reflection panel 4 are all rectangular. The diffusion panel 2, the light guide panel 3, and the reflection panel 4 are attached to the three side walls of the notch groove 101, and a gap is formed between the diffusion panel 2, the light guide panel 3, the reflection panel 4 and one side wall of the notch groove 101. The LED light bar 6 is arranged in the gap. This structure can stably fix the LED light bar 6. Refer to Figure 8 , at the same time, for the convenience of automatic assembly, the width of the LED light bar can be made wider, which is convenient for the manipulator to assemble. However, the width of the LED light bar in the prior art is slightly larger than the width of the lamp beads, which is not convenient for automatic assembly.

[0063] The shapes of the notch groove 101, the diffusion panel 2, the light guide panel 3, and the reflection panel 4 are not limited to rectangles. In some embodiments, they can also be designed into square, diamond and other shapes according to design requirements. Correspondingly, the shape of the LED light bar 6 is adaptively designed.

[0064] In some embodiments of the present utility model, the size of the LED light bar 6 is configured to be able to fill the gap. This structure can make the light bar 6 just be stuck in the gap between each panel layer and the groove side wall 1012 to fix the LED light bar 6.

[0065] Refer to Figure 11 , in some embodiments of the present utility model, the surface light source rear cover block 201 is wedge-shaped and includes an inclined guiding surface 2011. When the surface light source rear cover 2 and the surface light source housing 1 are assembled, the inclined guiding surface 2011 faces the side of the surface light source housing 1, forming an inclination towards the outside of the surface light source rear cover 2. This structure enables the rear cover block 201 to be guided into the card slot 101 during the assembly of the surface light source rear cover 2 and the surface light source housing 1, facilitating the installation between the two.

[0066] In some embodiments of the present utility model, a wiring terminal 601 is arranged on the LED light bar 6, and a notch 202 is formed on the surface light source rear cover 2. After the surface light source rear cover 2 and the surface light source housing 1 are assembled, the wiring terminal 601 is located at the position where the notch 202 is located. In addition, an opening 203 is also formed in the main body part of the surface light source rear cover 2, which is a rectangular opening, and a weight reduction groove 204 is formed on the surface of the surface light source rear cover.

[0067] In some embodiments of the present utility model, at the side wall of the surface light source housing 1 where the card slot 101 is located, a guiding structure is formed from the notch of the card slot 101 towards the edge of the side wall of the light source housing. When the surface light source housing 1 is assembled with the surface light source rear cover, the guiding structure cooperates with the rear cover block 201.

[0068] Refer to Figure 7, in some embodiments of the present utility model, the guiding structure is a guiding groove 102. A gap is provided between the guiding groove 102 and the notch of the clamping groove 104. The guiding groove 102 is located closer to the notch of the side wall of the notch groove 101. The groove wall of the guiding groove 102 in contact with the rear cover clamping block 201 forms an inclined surface, which inclines towards the outside of the surface light source housing from the bottom of the guiding groove to the notch of the guiding groove. The inclined surface of the guiding groove 102 fits with the guiding surface of the rear cover clamping block 201, guiding each other and applying a force to complete the assembly of the surface light source housing 1 and the surface light source rear cover 2.

[0069] In some embodiments of the present utility model, a clamping pin 103 is provided on the end surface of the surface light source housing 1. In this embodiment, the clamping pin 103 is provided on the end surface of the notch of the notch groove 101 and has an L-shaped structure.
