They diffuse the lateral light output of the Sideview LED arranged in the double-sided light source assembly 12 and the single-sided light source assembly 21 into a uniform light source facing the light source, forming three sets of independently separable light output areas.

[0091] Specifically, each of the single-sided light source components 21 includes: a second PCBA board 211 and a plurality of third LEDs 212, wherein the plurality of third LEDs 212 are arranged in an array on the second PCBA board 211, and the lateral independent light source is provided through the third LEDs 212.
