Abstract: A light-emitting module structure includes a substrate, a plurality of light-emitting diodes (LEDs) disposed on the substrate, and a light-guiding layer covering the light-emitting diodes. The light-guiding layer has an upper surface, the upper surface has a plurality of recesses, and the recesses are above the light-emitting diodes or between the light-emitting diodes. This light-emitting module structure can improve the brightness and uniformity of the light-emitting module.
