LENS, LED LIGHT SOURCE UNIT HAVING THE LENS AND LED LIGHT SOURCE MODULE INCORPORATING THE UNIT

摘要

A lens includes a light incident face receiving light from an LED light source, a light exit face, and a connecting face interconnecting the light incident face and the light exit face. The light exit face is a convex face. The connecting face includes a plurality of inclined reflecting planes located at a circumferential periphery of the lens and extending downwardly and inwardly from a position near to an outer edge of the light exit face toward the light incident face. The inclined reflecting planes of the connecting face are positioned around an optical axis of the lens. An LED light source module includes a plurality of the lens each diverging light from a corresponding LED light source and a light diffuser having a plurality of light diffusing units each over a corresponding lens. Each light diffusing unit has a shape of the regular hexagon.
