A metal-halide lamp is an electrical lamp that produces light by an electric arc through a gaseous mixture of vaporized mercury and metal halides [ 1][ 2] (compounds of metals with bromine or iodine ). It is a type of high-intensity discharge (HID) gas discharge lamp. [ 1] Developed in the 1960s, they are similar to mercury vapor lamps, [ 1 ...
However, mercury-vapor lamps are falling out of favor and being replaced by sodium-vapor and metal-halide lamps. Metal-halide and ceramic metal-halide lamps can be made to give off neutral white light useful for applications where normal color appearance is critical, such as TV and movie production, indoor or nighttime sports games, automotive ...
The ceramic metal halide is a variation of the metal-halide lamp which is itself a variation of the old (high-pressure) mercury-vapor lamp. A CMH uses a ceramic arc tube instead of the fused quartz arc tube of a traditional metal halide lamp. Ceramic arc tubes allow higher arc tube temperatures, which some manufacturers claim results in better ...
Gas lamps gradually started replacing oil street lamps in the United States, beginning in the first quarter of the 19th century. [ 3] The first street in the world to be illuminated by gaslight was Pall Mall in London, starting in 1807. [ 1][ 5] The first US city to use gas street lights was Baltimore, starting in 1817. [ 4]
A sodium-vapor lamp is a gas-discharge lamp that uses sodium in an excited state to produce light at a characteristic wavelength near 589 nm . Two varieties of such lamps exist: low pressure and high pressure. Low-pressure sodium lamps are highly efficient electrical light sources, but their yellow light restricts applications to outdoor ...
Hydrargyrum medium-arc iodide ( HMI) is the trademark name of Osram 's brand of metal-halide gas discharge medium arc-length lamp, [1] made specifically for film and entertainment applications. Hydrargyrum comes from the Greek name for the element mercury . An HMI lamp uses mercury vapour mixed with metal halides in a quartz -glass envelope ...
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. Metal halide lamps produce almost white light, and attain 100 lumen per watt light output. Applications include indoor lighting of ...
