[0002] Surface light source refers to the mode of light emission. When the light source is far away from the receiver and the received light is close to a parallel line, the light source can be called a surface light source. Compared with LED point light sources and ordinary lamp light sources, existing surface light sources such as flat panel light sources and LED surface light sources have the characteristics of soft light, no harm to the eyes, power saving, and natural light.

The inner walls on both sides of the left and right sides of the outer frame 1 are fixedly connected with limit blocks 4 for supporting the light guide plate 2, so that the limit blocks 4 are convenient for supporting the reflector 3 in the outer frame 1.

[0035] In this embodiment, the fixed structure includes a limit plate 301 fixedly connected to the bottom of the reflector 3, a movable plate 14 movably connected to the inside of the outer frame 1, a clamping block 1401 fixedly connected to the left side of the movable plate 14 and clamped to the limit plate 301, and a shifting component installed inside the outer frame 1 and used to adjust the position of the movable plate 14.

[0042] The working principle of the above embodiment is:

[0043] The assembly structure of the side-entry surface light source, when assembling, firstly needs to place the reflector 3, the light guide plate 2 and the diffuser 5 at the predetermined positions on the outer frame 1, and then drive the threaded sleeve 12 to rotate by turning the knob 13, so that the movable plate 14 can move in the outer frame 1 with the rotation of the threaded sleeve 12, until the clamping block 1401 uses the clamping groove 302 to extend into the limit plate 301, so as to limit the movement of the limit plate 301; at the same time, the set threaded rod 11 can drive the push rod 10 to move leftward with the rotation of the threaded sleeve 12, so that it is convenient for the push rod 10 to push the push block 8 to the left by using the push block 1001, so that the push block 8 drives the positioning rod 7 to move leftward, and the positioning rod 7 passes through the plug block 501 by using the positioning hole 502, so as to limit the movement of the plug block 501, thereby realizing the stable installation of the reflector 3, the light guide plate 2 and the diffuser 5, and completing the assembly of the surface light source module;

[0044] When in use, the optical refraction and diffuse reflection principles of the light guide plate 2 can be used to convert the light of the side-entry light source LED light strip 6 into a surface light source, which is emitted from the diffuser plate 5 to achieve a uniform light emission effect; in this process, the side edge line of the reflector 3 and the diffuser plate 5 that are separated corresponds to the edge line of the outer frame 1, which can ensure the flatness of the light-emitting surface of the surface light source module, not only improving the aesthetics of the surface light source module, but also preventing dust and liquid from falling into the outer frame 1 along the outer wall of the surface light source plate, thereby improving the protection effect of the light source in the outer frame 1.
