Light source method for electric light source illumination

A power source that uses visible energy to generate visible light is called an electric light source (long-side illumination). Lighting with electric light source, called electric lighting:

According to the different methods of illuminating, electric lighting can be divided into four categories: resistance illuminating, arc illuminating, gas illuminating and phosphor illuminating; according to the properties of Ming, it can be divided into general lighting, local lighting and decorative lighting.

Light source method of electric light source

1. Resistive luminescence, which is a method of illuminating by the use of the inherent resistance of the conductor itself to generate a thermal effect to achieve a hot level. Such as commonly used incandescent lamps, iodine tungsten lamps.

2. Arc illuminating, which is a force method that uses a discharge of two electrodes to generate a high thermal arc and emit light. Such as carbon lamps.

3. Gas luminescence, which is a method of injecting a rare gas and a metal vapor into a transparent glass tube, and using a two-pole discharge to cause the gas to heat up and emit light. Such as sodium lamps, xenon lamps, etc.

4. Fluorescent luminescence, which is a kind of injecting a thin gas or a trace of metal into a transparent glass tube, and coating a phosphor on the inner wall of the glass tube. After the discharge of the two poles, the luminescence of the gas is used to absorb the phosphor and then emit another A method of light, such as fluorescent lamps.
