In order to ensure electrical safety, all the parts of the lamps that are energized must be insulated with insulating materials. This measure of personal safety of the lamps is called protection against electric shock. According to the method of protection against electric shock, the lamps and lanterns can be divided into 0, I, II and III total 4 categories.

Category 0 protection depends on basic insulation, that is, where there is a high degree of safety in the accessible parts and insulation between the housing and the live parts, and the installation and maintenance of the lamps are convenient. Such as the air drying, dust, wooden floor and other conditions under the chandelier, ceiling lamps and so on.

In addition to the basic insulation, type I, the accessible part and the shell are grounded, and once the basic insulation fails, there is no danger.
For metal housing fixtures, such as floodlights, street lights, garden lights, etc., to improve safety.

Class II addition to basic insulation, supplemental insulation, double insulation or price reinforced insulation, improve safety,
With good insulation and high safety, it is suitable for lamps that are often in poor touch, such as lamps and portable lights.

Class III uses an extremely low safety voltage (AC rms < 50V) and no voltage above this value will be generated in the lamp.
Lamps have a high degree of safety and are used in harsh environments such as machine tool work lights and children's lights.

Auto Headlight Bulbs

Headlight is Powerful light at the front of a vehicle. One car usually needs a pair or two pair of bulbs. It is depend on the original car design. Driver need power light to illuminate the road in front of them to keep them safe, so the halogen bulbs are usually been used as headlight. Halogen bulb can generate more light and has better working life hours. The supply voltage of halogen lamp is usually divided into ac 220V and dc 12V and 24V. The halogen lamp is made of tungsten, but it is enclosed in a smaller quartz glass shell. Normally, the halogen bulb will create ultraviolet when light, so we must use quartz coating to prevent head lamp been damaged by the ultraviolet generated by halogen bulb. To generate more light, the filament be heated to the very high temperature, so halogen bulb is hotter than a normal bulb.
