A gas discharge lamp is a lamp that emits light by discharging a gas, a metal vapor, or a mixture of several gases and metal vapors. An electric light source converts electric energy into light by gas discharge. Many types of gas discharge are used, and glow discharge and arc discharge are used in many cases. Glow discharge is commonly used for neon and indicator lights. The arc discharge can have a strong light output, and the illumination 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 lighting. Gas discharge lamps are extremely widely used in industrial, agricultural, medical and scientific research fields.
Various gas discharge lamps are composed of a bulb, electrodes and a discharge gas, and the basic structures are different. The bulb shell is in vacuum airtight sealing connection with the electrode, and discharge gas is filled in the bulb shell. The gas discharge lamp cannot be connected to the circuit alone and must be connected to the circuit together with auxiliary appliances such as a trigger, a ballast, etc. to start and operate stably. The starting of discharge lamps usually applies voltages higher than the 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 produce a strong light by means of an arc discharge in the lamp vessel, in combination with an inert gas or metal vapor filling the lamp vessel.
The radiation spectrum of the high-pressure gas discharge lamp is selectable. By selecting a suitable luminescent substance, the radiation spectrum can be concentrated at the desired wavelength, or several luminescent substances can be used simultaneously in order to obtain an optimal combined spectrum. With high efficiency, they can convert 25-30% of the input electrical energy into light output. Long service life. Up to 1 ten thousand hours or more than 2 ten thousand hours. The light output maintenance characteristics are good and still provide 60-80% of the initial light output at the end of life.
The types of high-pressure gas discharge lamps include high-pressure sodium lamps, (fluorescent) high-pressure mercury lamps, xenon lamps, and metal halide lamps.
