Lamp for producing light intensity uniformity |
摘要 |
A circular light emitting filament is positioned adjacent an annular light blocking lip extending from a bowl-shaped reflector. A substantially conical reflector portion extends from the cancer of the reflector and has an apex coincident with the lamp projection axis. The result is that all of the light is reflected before being projected from the lamp and good light intensity uniformity is attained at the illuminated scene.
