The gas discharge lamp is a lamp that emits light by discharge of a gas, metal vapor, or a mixture of several gases and metal vapor. An electric light source converts electric energy into light by means of a gas discharge. Gas discharges are of many types and most commonly used are glow discharges and arc discharges. Glow discharges are commonly used for neon and indicator lights. The arc discharge can have strong light output, and the lighting source adopts the arc discharge. Fluorescent lamps, high-pressure mercury lamps, sodium lamps and metal halide lamps are the most widely used gas discharge lamps for illumination. Gas discharge lamps are used in a very wide range of applications in the industrial, agricultural, medical and scientific research fields.

Various gas discharge lamps are composed of a bulb, electrodes and discharge gas, and the basic structures are different. The bulb shell and the electrode are sealed in a vacuum airtight mode, and discharge gas is filled in the bulb shell. The gas discharge lamp can not be connected into the circuit independently, and can be started and stably operated only by connecting the gas discharge lamp into the circuit together with auxiliary appliances such as a trigger, a ballast and the like. The discharge lamp is usually started by applying a voltage higher than the power supply voltage, sometimes up to several thousand volts or more. Therefore, there is a fatal danger to the human body when the human body contacts the lamp tube to change the lamp. High-pressure gas discharge lamps are a type of gas discharge lamp that produces intense light by an arc discharge in a lamp tube in combination with an inert gas or metal vapor filled in the lamp tube.

The high-pressure gas discharge lamp has a selective radiation spectrum. By selecting suitable luminescent substances, the radiation spectrum can be focused on the desired wavelength, or several luminescent substances can be used simultaneously in order to obtain an optimum combined spectrum. They have high efficiency and can convert 25-30% of input electric energy into light output. The service life is long. The usage time is up to 1 ten thousand hours or more than 2 ten thousand hours. The light output maintaining characteristic is good, and 60-80% of initial light output can be provided at the end of service life.

The high-pressure gas discharge lamp is classified into a high-pressure sodium lamp, a (fluorescent) high-pressure mercury lamp, a xenon lamp, a metal halide lamp, and the like.
