Metal halide lamp is a new light source developed on the basis of high pressure mercury lamp to improve the light color. It has good light color and high luminous efficiency. The commonly used sodium, thallium and indium lamp is one of them. Its structural wiring is shown in the right figure below.

。

The working principle of 400W sodium thallium lamp is as follows: after power supply is switched on, current through heating coil and bimetal sheet makes bimetal sheet bent and separated from static contact, thus generating high-voltage pulse, which ignites the discharge of lamp tube.

After ignition, the heat of discharge keeps the bimetal sheet bent, separated from the static contact, and the sodium, thallium and indium lamp enters the stable working state. A special trigger is required for 1000W sodium, thallium and indium lamp.

When installing metal halide lamp, attention should be paid to: the temperature of the outer glass shell of the lamp is higher, the heat dissipation should be considered when matching the lamp, and the lamp tube must be used in conjunction with the corresponding ballast. Metal halide lamps without external glass shells should be covered with glass because of the strong ultraviolet radiation. If there is no glass cover, the suspension height of the lamp s
