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 consists of reflector 12 , lamp housing 14 , inner elements 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 off the front end of the reflector 12 .

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

Abstract

An integral HID reflector lamp may be formed with an HID (14) held in a reflector (12). An inner element (16) 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 (18), 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 (20) spans at least one side of the circuit board and forming an EMI shielding. An outer cover (22) 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, in particular to electric HID lamps. More particularly, the invention relates to high intensity discharge lamps with reflectors for screw sockets. Background technique [0002] High Intensity Discharge (HID) lamps are very efficient, with a lumen-per-watt factor of 100 or higher. HID lamps also provide excellent color reproduction. Existing HID lamps require separate starting and ballasting devices and therefore cannot be used interchangeably with incandescent lamps in standard sockets. This limits their market application in the professional world and makes them largely unavailable to the general public who might benefit from this technology. With the advent of circuit miniaturization, ballast and start-up circuits have become smaller, but their performance is affected by the outside operating temperature. HID lamps are known to generate significant amounts of heat, and this factor, among others, of...
