Description

Lamp holder

Technical Field

The invention relates to the technical field of electrical components, in particular to a lamp holder.

Background

An electric bulb (or bulb), known by the precise technical name incandescent lamp, is a lamp that emits light by heating a filament (modern, usually tungsten filament) to incandescent by means of electrical resistance. The outer periphery of the electric bulb is made of glass, and the filament is kept under vacuum, or under inert gas at low pressure, and functions to prevent the filament from being oxidized at high temperature. With reference to incandescent lamps, electric lamps are generally considered to be invented by the american Thomas Edison. But given serious consideration, another american, henry, gobier than edison, invented the same principles and materials decades earlier. In 1801, a chemist in England electrified a platinum wire to emit light, and in 1810, the chemist invented a candle and illuminated by an arc between two carbon rods. In 1854, a carbonized bamboo filament was placed under a vacuum glass bottle and powered to emit light.

A bulb, an illumination source that emits light and heat by electric energy, was invented by henry gobier (edison actually found a suitable material, i.e., invented a highly practical incandescent lamp, and a bulb appeared as early as 1854). The most common function of a light bulb is illumination.

A lamp holder is a device that fixes the position of the lamp and connects the lamp contacts to the power supply. The lamp holder can not be detached and maintained after the existing lamp holder is installed, and meanwhile, after the bulb is installed on the lamp holder, due to the fact that the position of the bulb is high, the bulb is contaminated after long-term use, the bulb is not convenient to clean, dust is easily attached to the bulb, and the irradiation brightness of the bulb is affected.
