LOOPED FRAME ARC TUBE MOUNTING ASSEMBLY FOR METAL HALIDE LAMP |
摘要 |
An arc tube mounting assembly (1) for a metal halide arc lamp (10) includes frame members (8, 9) for supporting an arc tube (2). The arc tube (2) is supported from above by a looped frame member (8) having a loop (8A) which extends along opposing sides, and across top and base ends (2A, 2B) of the arc tube (2), thus evenly distributing the current to discharge electrode 7, thereby cancelling magnetic forces which could displace the arc from the center of the arc tube (2), resulting in improved lumen maintenance and extended life. A centering circle (8B) of the frame member (8) wraps around the lower ceramic end plug (4), providing coaxial alignment of the arc tube (2) and the tubular outer envelope (11). |
