Abstract
An exemplary lens for regulating light of an LED includes a light guiding portion and a latching portion extending downwardly from the light guiding portion. The light guiding portion includes a top surface and a bottom surface opposite to the top surface. A center of the bottom surface is depressed toward the top surface to form an optical concave. The latching portion is formed at the bottom surface and located around the optical concave surface. The latching portion defines an engaging hole to fittingly receive the LED therein. A light source module having the lens is also provided.
Claims16
A lens for regulating light of an LED (light emitting diode) package comprising:
- a light guiding portion comprising a top surface and a bottom surface opposite to the top surface, a center of the bottom surface being depressed toward the top surface to form an optical concave;
- and
- a latching portion extending downwardly from the bottom surface and located around the optical concave, the latching portion defining and surrounding an engaging hole, the engaging hole being configured to fittingly receive at least a top end of the LED package therein.
A light source module comprising:
- a substrate having a flat top surface;
- an LED package mounted on the substrate and electrically connecting with the substrate;
- and
- a lens disposed on the substrate, the lens comprising a light guiding portion and a latching portion extending downwardly from the light guiding portion, the light guiding portion comprising a top surface and a bottom surface opposite to the top surface, a center of the bottom surface being depressed toward the top surface to form an optical concave, a latching portion being formed at a bottom surface and located around the optical concave, the LED package being fittingly received in an engaging hole defined by the latching portion.
