Title (EN) LIGHT SOURCE FOR A PROJECTION SYSTEM HAVING A LIGHT ABSORPTION LAYER
(FR) SOURCE LUMINEUSE POUR SYSTEME DE PROJECTION A COUCHE D'ABSORPTION DE LUMIERE
Abstract: front page image
(EN)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).
(FR)Un réflecteur (20) utilisé dans un système de projection (10) comprend un substrat métallique anodisé (22) pourvu d'une couche d'oxyde métallique (40). La couche d'oxyde métallique (40) comporte une pluralité de pores (42). Un pigment absorbeur de lumière (44) est déposé dans chaque pore (42) de sorte que le pigment absorbeur de lumière (44) et la couche d'oxyde métallique (40) forment ensemble une couche d'absorption de lumière (24) sur le substrat métallique (22).
