Abstract:Optical lenses are used in signal lighting to control intensity distributions. Brightness and
viewing angle are two essential requirements that have to be considered in manufacturing a traffic
signal lamp. This paper discusses design considerations for microstructure optics designed for LED
traffic signal light, strategies for obtaining particular intensity distributions, optical functions of the
lens and matters concerning the manufacturing process. The mould inserts of the optical surfaces
were machined by C… Show more
