Abstract
A light gathering module (10) has a body (12) with a first end (14) comprising a single light transmitting surface (16) and a second end (18) having a plurality of arms (20), each arm (20) having an independent light gathering terminus (22) that is rectangular. In a preferred embodiment of the invention, the first end (14) of the body also is rectangular. The light gathering module (10) can be fabricated from acrylic, plastic, glass or other suitable material and preferably has no cladding so that light output I maximized. When combined in a housing (32) with a projector lens (34) the light gathering module (10) provides a vehicle headlamp (30).
