Abstract: Alight source module includes a substrate, multiple light sources disposed on the substrate, and multiple three-dimensional optical control structures located above the light sources. Each optical control structure includes a top portion disposed corresponding to the light source and has multiple top light transmissive patterns, a first side portion, and a second side portion. A total area of top light transmissive patterns within a top region divided by an area of the top region is T. The first and second side portions are respectively connected to the top portion, and each has multiple side light transmissive patterns. A total area of multiple side light transmissive patterns within a side region divided by an area of the side region is S. The patterns satisfy: 0.3×(B/A)
