LIGHT SOURCE MODULE AND BACKLIGHT MODULE

摘要

Provided is a light source module (400), comprising at least one light source (610) and at least one secondary lens (620). The secondary lens (620) comprises an incident curved surface (622), an emergent curved surface (623) and a bottom surface (621). The incident curved surface (622) protrudes inwards to form an empty cavity (624). The light source (610) is disposed in the empty cavity (624). The bottom surface (621) comprises multiple prism micro-structures. Rays generated by the light source (610) are incident to the incident curved surface (622), and enter the secondary lens (620). The rays reaching the bottom surface (621) are emitted out from the emergent curved surface (622) after passing through the prism micro-structures. The light source module (400) may reflect the rays reflected by the emergent curved surface (623) back into the secondary lens (620) through the prism micro-structures. Therefore, the light source module (400) may reduce the total amount of ray dissipation, so the rays emitted by the light source (610) are used better.
