Abstract: A lens includes an optical axis, a light source recess arranged through the optical axis, a reflection surface crossing through the optical axis, and a critical reflection surface which is arranged in a spaced relationship with the optical axis. The critical reflection surface is arranged between the light source recess and the reflection surface and receives the light from the light source recess and the reflection surface and reflects the light from the light source recess and the reflection surface towards the reflection surface. The emission light of the lens is light emitted forward of the light emitting surface which is reflected via the reflection surface and the critical reflection surface. Therefore, people cannot receive directly light emitted forward of the LED after it cross through the lens. In result, high luminance light from the LED is prevented from ripping into eyes, which achieve the aim of anti-glare.
