Abstract
A heat sink for use in a lamp assembly comprising a body having a first portion that lies in a first imaginary plane and that is adapted to receive at least one light source for emitting light rays and a shield that extends from the first portion. The shield blocks at least a portion of the light rays to facilitate reducing or eliminating glare or back dazzle. The shield is integrally or monolithically formed in the body and lies in a second imaginary plane that is generally orthogonal to the first imaginary plane.
