Abstract
The invention relates to a total internal reflection micro lens array for a wide-angle lighting system. The micro lens array includes a plurality of Fresnel lens structures formed on a same optical incidence surface. Each of the Fresnel lens structure includes a plurality of grooves, each having a reflecting surface and a refractive surface. Incoming radiation incident through the incidence surface of the lens structure is internally totally reflected by the reflecting surface, refracted by the refractive surface and exits the lens structure.
