Par lamp with negative draft neck and method of assembling the lamp |
摘要 |
A tungsten-halogen or HID parabolic reflector lamp construction and assembly method is described that improves lamp performance by increasing the area of the parabolic reflective surface while reducing manufacturing cost by simplifying assembly. The reflector has a small opening just large enough to accommodate the light source capsule and a reverse draft angle in the neck. The capsule is attached directly or indirectly to a standard medium screw threaded base minimizing the number of separate lamp components and assembly operations.
