The present invention relates to a socket, and more particularly, to a socket having an LED light emitting device that can be used by integrating and tightening a socket to which an LED light emitting device is coupled to an existing light housing installed on a ceiling or a wall, such as an incandescent lamp.

In general, a light is installed on a wall or a ceiling of an office or a home to create and decorate an indoor atmosphere. Such a light is installed on a wall or a ceiling, and a socket formed integrally with a light bulb is tightened and fastened inside the housing. Made of structure.

On the other hand, the light bulb is fastened to the light housing is mainly used incandescent bulbs, krypton bulbs, three-wavelength bulbs, incandescent bulbs are the most comfortable to emit light with the closest to the sun's rays, but there is a drawback of large power consumption.

In addition, it uses a krypton bulb that can be used in places where it is difficult to change the bulb frequently because it has a lifespan of 10 times longer than a normal bulb.

Or recently, three-wavelength lamps are mainly used, with a power of 20W watts, the brightness of 100 watts of incandescent bulbs, resulting in more than 80% energy savings, softer, more natural, and more expensive than residual wavelength fluorescent lamps. Considering the effect and the lifetime of up to 10,000 hours, it is rather economical.

On the other hand, in recent years, in order to solve the above problems, LEDs have been used a lot as a light source of a luminaire.

The light emitting diode (LED) is a light emitting diode that changes the electrical signal to infrared or light by using the characteristics of the compound semiconductor, and is widely used for display devices of various mechanical devices, lighting for entering the exterior of automobiles, internal devices, and electronic displays.
