INSTRUCTIONS: [Technical Field] The present invention relates to the field of optical systems, and more particularly to an edge-lit light-emitting diode light source module. [Prior Art] At present, Light Emitting Diode (LED) has been widely used in many fields due to its low power consumption, long life, small size, and high brightness. A novel light-emitting diode can be found in Daniel A. Ref. Steigerwald et al., IEEE Journal on Selected Topics in Quantum Electronics, Vol. 8, No. 2, March/April 1102, Illumination With Solid State Lighting Technology. The diode light source module can be divided into a direct type and a side light type according to the distribution position of the semiconductor light emitting element LED. Due to the thicker mold set, it does not conform to the trend of light, thin and short. Therefore, at present, it is mainly based on the sidelight type. For the edge-lighting light-emitting diode light source module, the semiconductor light-emitting element LED is usually disposed on one side of the light-guiding plate, and the light-guiding plate breaks the reflection condition of the light through the diffusion point of the bottom surface, so that the light is emitted from the front surface of the light guide plate, so that the light is emitted from the front surface of the light guide plate. The light guide plate emits light uniformly. In order to cooperate with the edge-lit LED light source module, a microlens can be generally disposed above the LED, and the light emitted from the LED is guided to the light guide plate through the microlens to improve the light utilization rate, but the LED is easily emitted. The light is uneven. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a side light type light emitting diode light source module with uniform light output. 6 201009257 ‘It includes: : a first light-emitting diode
