Kostengünstiger Reflektor mit ausgezeichneter Hitzebeständigkeit |
摘要 |
In a reflector (10) including a mirror base member (11) having a concave surface, a reflecting film (12) is formed on the concave surface. For preventing the fragments of the broken lamp from flying forward, a protective glass plate (13) is attached to the mirror base member. At least one of the mirror base member and the protective glass plate is made of a glass member whose mechanical strength is enhanced. The mechanical strength of the glass member may be enhanced by ion exchange. <IMAGE> |
