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 ).

Claims (7)

1. An automotive headlamp for forward road illumination comprising:

a housing;

a piano-convex projector lens in a front portion of said housing;

a light gathering module positioned in said housing, comprising:

a rigid body with a first end comprising a single light transmitting surface opposite a second end comprising a plurality of arms, each arm having an independent light gathering terminus that is rectangular and encompasses a plurality of light emitting diodes, said first end being operatively associated with said plane side of said plano-convex projector lens.

2. The automotive headlamp of claim 1 wherein said first end of said body is rectangular.
