[0009] As the utility model further improves, the recess is in the conical structure, and the recess gradually increases in diameter from top to bottom.

[0010] The utility model has the advantages of the following:

[0011] In this high beam module, the silicone lens is positioned on the circuit board via a bracket to cover the LED beads. The light emitted by the LED beads passes directly through the silicone lens and is emitted in parallel. The overall assembly structure is simple, and the light passes through less medium when it is emitted, which effectively reduces light attenuation and improves light utilization. The outer diameter of the silicone lens gradually narrows from the incident direction to the emission direction, which can control the emission angle of the light within a small range, resulting in good lighting effect.
