LIGHT SOURCE FOR A PROJECTION SYSTEM HAVING A LIGHT ABSORPTION LAYER

摘要

A reflector (20) for use in a projection system (10) comprises an anodized metal substrate (22) having a metal oxide layer (40). The metal oxide layer (40) has a plurality of pores (42). A light absorbing pigment (44) is deposited into each of the pores (42) such that the light absorbing pigment (44) and the metal oxide layer (40) form a light absorbing layer (24) on the metal substrate (22).
