Multi-functional mini-reflector in a ceramic metal halide lamp

Номер: US20120119637A1
Автор: Lei Deng
Принадлежит: General Electric Co

A light assembly includes a metal halide light source having an arc tube with first and second legs extending from a discharge chamber. A light transmissive capsule surrounds the light source. A reflector is received in the capsule and has a large diameter, annular first portion that receives light from the discharge chamber and is dimensioned to operatively engage an inner surface of the capsule to mount the reflector assembly and light source relative to the capsule. In addition, a small diameter portion of the reflector assembly is received around the first leg. By electrically interconnecting the reflector with the second electrode assembly, namely the support leg, and positioning the small diameter portion closer to the first electrode assembly than the dimension between the electrode terminal ends allows the reflector to also serve as an ignition aid. The reflector is formed of a material that serves as a heat shield for the seal glass in the first leg and also serves as a heat shield for the capsule seal region.
