ASYMMETRICAL LIGHT DISTRIBUTION TOTAL INTERNAL REFLECTION LENS

摘要

An asymmetrical light distribution total internal reflection lens adapted to be disposed on a light source is provided. The asymmetrical light distribution total internal reflection lens includes a body, a light incident refraction part, a light emitting surface and a total reflection surface. The body has a center axis. The light incident refraction part is located on a bottom of the body, and the light incident refraction part is a notch, used to dispose the light source. The light emitting surface is located on a top of the body and has a first surface and a second surface which are connected and not parallel to each other. The total reflection surface is located on a side part of the body, and the total reflection surface is connected with the light incident refraction part and the light emitting surface.
