Mounting assembly for high output electrodeless lamp
View Patent ↗A mounting assembly ( 10 ) for an electrodeless 1 amp ( 100 ). The mounting assembly ( 10 ) comprises a fixture housing ( 14 ) having an inner surface ( 16 ) and an outer surface ( 18 ). The fixture housing is preferably made from aluminum. Spaced-apart heat sinks ( 20, 21 ) are affixed to the inner surface ( 16 ) of the fixture housing ( 14 ). A reflector ( 22 ), which is preferably concave, as is the fixture housing, is positioned within the fixture housing ( 14 ). The reflector ( 22 ) contains two apertures ( 24, 26 ) that are aligned with the heat sinks ( 20, 21 ). Thermal insulators ( 28, 29 ) are positioned in the apertures and surround the heat sinks, thus thermally isolating the reflector from the heat sinks. The lamp ( 100 ) is mounted in the fixture housing by attaching brackets ( 40, 42 ), which surround the ferrite transformer cores of the lamp, directly to the top surfaces of the heat sinks ( 20, 21 ). Mounting is preferably accomplished by having threaded holes formed in the heat sinks and fixing the brackets in place via screws through the legs ( 44 ) and screw receiving slots ( 46 ).
1. A mounting assembly for a high output electrodeless lamp comprising;
a fixture housing having an inner surface and an outer surface;
a pair of spaced-apart heat sinks affixed to said inner surface of said fixture housing and extending therefrom:
a reflector positioned within said fixture housing, said reflector containing two apertures aligned with said heat sinks;
a thermal insulator surrounding each of said heat sinks in said apertures and thermally isolating said reflector from said heat sinks; and
an electrodeless lamp mounted to said heat sinks.
2. The mounting assembly of claim 1 wherein said heat sinks are formed integrally with said fixture housing.
3. The mounting assembly of claim 1 wherein said heat sinks are formed distinct from said fixture housing and are welded thereto.
4. The mounting assembly of claim 3 wherein said heat sinks are a different material than said fixture housing.
5. The mounting assembly of claim 1 wherein said fixture housing is concave.
6. The mounting assembly of claim 5 wherein said reflector is concave.
7. The mounting assembly of claim 1 wherein said thermal insulator is formed from a material selected from ceramic, silicon or rubber.
