High-intensity discharge lamp

(redirected from HID lamp)

High-intensity discharge lamp

A lamp that produces light by passing an electrical current through a gas or vapor under high pressure. HID lamps have a long life and consume little energy to produce a great amount of light. However, they distort the color rendition of objects and are used mostly as ambient lighting for commercial interiors. Ballasts are required to start the lamp. Types include mercury vapor lamps, metal-halide lamps, and sodium vapor lamps. The different types contain different gases, which produce different colors of light.

high-intensity discharge lamp

One of a group of mercury, metal halide, or high-pressure sodium lamps.

But even after decades of research the understanding of the physics inside the lamp is still challenging [Araoud 2010, Brok 2006, Dabringhausen 2005, Dreeben 2011, Hartel 1999, Wei[beta] 2005], where the examination of a multi component plasma is a much more complex task compared to a 'simple' mercury HID lamp, which is the 'white mouse' of HID lamp research.

Remember that the increased directionality and control offered by today's LED fixtures over older HID lamp and optic combinations is part of what allows them to produce equal or better light using less total lumens, and significantly less energy.
