Embodiment Construction

[0016] figure 1 A side perspective view of a preferred embodiment of the HID reflector lamp 10 is shown. HID reflector lamp assembly 10 is made of reflector 12 , lamp housing 14 , internal components such as inner cover 16 , circuit board 18 , heat sink 20 , outer cover 22 and threaded base 24 . A front cover lens may also be used to close the front end of the reflector 12 .

[0017] figure 2 A side perspective view of a preferred embodiment of the assembly of the integral HID light capsule 14, support ring 74, and contact clip 52 is shown. The HID capsule 14 has a wall 26 defining an enclosed space 28 , and a sealed end 30 with at least two electrical connections, a first lead 32 and a second lead 34 . The preferred capsule 14 is a tubular lamp capsule with press-fit sealed ends 30 . The preferred lamp housing 14 includes ceramic lamps 36 such as Power Balls, but any similar small ceramic or quartz HID lamp configuration would also be suitable for use in the present HID ...

Abstract

An integral HID reflector lamp may be formed with an HID held in a reflector. An inner element is mechanically coupled to the reflector. The inner element is formed with a first mechanical coupling to mate with the reflector, a second mechanical coupling to mate with a circuit board, and an electrical coupling to at least electrically couple one of the leads to the circuit board. A circuit board has an edge mechanically coupled to the inner element and electrically connected to the leads by an electrical coupling on the inner element. A heat sink spans at least one side of the circuit board and forming an EMI shielding. An outer cover encloses the heat sink, circuit board, and inner element and coupled to the assembly of the reflector, HID lamp, inner element, and heat sink with each elements of the assembly clipped together.

Description

technical field [0001] The present invention relates to electric lamps and in particular to electric HID lamps. More specifically, the present invention relates to HID lamps with reflectors for use in threaded sockets. Background technique [0002] High intensity discharge (HID) lamps can be very efficient with a lumen / watt factor of 100 or higher. HID lamps also offer excellent color rendering. Previously, HID lamps required separate starting and ballasting equipment, and thus could not be used interchangeably with incandescent lamps in standard sockets. This limits their market use to professional applications and essentially shuts them out of the general public who could benefit from the technology. With the advent of miniaturized circuits, ballasts and starting circuits have become smaller, but their performance will be affected by the ambient operating temperature. It is well known that HID lamps emit a great deal of heat, and this and other factors often keep the s...
