ABSTRACT:
A total internal reflection element having a plurality of total internal reflection faces and a plurality of exit faces which redirect light from a light source into a side direction. The total internal reflection element is manufactured by injection molding.The curved entry faces have the optical effect of concentrating incident light onto a center of the corresponding total internal reflection face. This allows light impinging on the total internal reflection face from a wider range of angles to be redirected for side projection through the desired exit face.The total internal reflection element is used in a signal. The signal has a housing and can be placed at a variety of heights.
