Abstract
A light guide includes a light input surface which has two first edges, an output surface parallel to and larger than the input surface, and two connecting surfaces, each of which interconnects the light input surface and said light input surface and has an inclined segment. Relationships of θ<θand L>(AD)/(tan θ) are satisfied, where θ is an included angle defined between extensions of the inclined segments of the connecting surfaces, θis a critical angle for total internal reflection associated with the light guide, (L) is a distance between the light input and output surfaces, and (AD) is a distance between a location of incidence of a light beam on the light input surface and one of the first edges.
