Abstract:
1. A light guide system, comprising: a light guide comprising a first surface, a second surface, and a third surface, wherein light entering through the first surface propagates along the light guide by total internal reflection between the second surface and the third surface; and elements that are arranged with respect to the light guide to disrupt the total internal reflection of the propagating light, each element in physical contact with a respective portion of the second surface, each contact element configured such that a portion of the light that is incident thereon is transmitted therethrough; and a respective reflector positioned to receive the light transmitted through each element, the reflector having a curvature such that the light is reflected back into the light guide and exits the light guide through the third surface; wherein the elements each comprise a contact portion that physically contacts the second surface and the contact portion is small compared to the reflectors such that the elements function as quasi-point sources.
