HID lamps produce different colors of light primarily through the use of various metal additives in the lamp's arc tube and the physics of the gas discharge process. [11] Metal Additives: HID lamps contain an arc tube filled with a mixture of gases, including a noble gas (like xenon). These metal additives are crucial for producing different ...
Like other gas-discharge lamps such as the very-similar mercury-vapor lamps, metal-halide lamps produce light by ionizing a mixture of gases in an electric arc.In a metal-halide lamp, the compact arc tube contains a mixture of argon or xenon, mercury, and a variety of metal halides, such as sodium iodide and scandium iodide. [7]
The lamp is powered by an electrical ballast, which regulates the current flow through the arc in the arctube, and an ignitor, to make the high voltage pulse that is necessary to start the arc in the arctube. Like all HID lamps, HQI lamps operate under high pressure and temperature, and require special light fixtures for safe use.
High-pressure lamps have a discharge that takes place in gas under slightly less to greater than atmospheric pressure. For example, a high pressure sodium lamp has an arc tube under 100 to 200 torr pressure, about 14% to 28% of atmospheric pressure; some automotive HID headlamps have up to 50 bar or fifty times atmospheric pressure.
The brilliance of a U-HID lamp can reach 80% in four seconds under normal temperature conditions, and can start working at 100% instantly after a re-ignition. Comparatively, the intensity of light from a U-HID lamp is at least three times stronger than a metal halide HID lamp in a color range of 4200K (cold light).
