ABSTRACT:
A lens used for a light-emitting diode (LED) includes a body having an axis and a retaining part, wherein the body of the lens is symmetrical about the axis. The lens is mounted onto an LED and further includes a first lens part and a second lens part. When entering into the first lens part, light rays will be totally reflected through the first lens part and the light rays emitted from the first lens part will approximately parallel to the axis. When the light rays emitted from the first lens part enter into the second lens part, they will be totally reflected, and the light rays emitted from the second lens part will be approximately perpendicular to the axis. Thus, the lens has a structure that may control the emitting direction of light emitted from an LED.
