A, metal halide lamp glow metal halide lamp process within a small metal halide filling and gas, from normal to trigger to shine a more minutes and can be divided into three stages. 1. The trigger stage. 2. Fire stage. 3. Normal light stage.

Second, metal halide lamp emitting mechanism of metal halide lamp rely mainly on the metal halide as luminescence materials, metal halide lamps with solid form exists within.

Three, metal halide lamp the biggest advantage is particularly high luminous efficiency, photosynthetic efficiency is as high as 80 ~ 90 Lm/W, normal light at produce less heat, so is a kind of cold light source. Because of the metal halide lamp spectrum is in the continuous spectrum based on the superposition of line spectrum, so dense colour developing index is particularly high, color is very good, reducing can reach 90%. In addition, metal halide lamp colour temperature is high, can reach 5000 6000 K, special the projector lamp can reach 7000 8000 K. In the same brightness conditions, the color temperature is high, the more bright eye feel.

Metal halide lamp with its high luminous efficiency, small volume and the widespread attention.
