Abstract
The utility model discloses an LED lamp holder. The light-emitting efficiency of an LED is decreased along with the increase of the temperature of the LED, so that heat dissipation of the LED is quite important. If the generated heat can not be timely emitted, the temperature of the periphery of a light-emitting unit can rise, the aging of a chip and the aging of packaged resin are accelerated, a welding point may be molten, the chip loses efficacy, and therefore the service life and the light-emitting performance of the LED are directly affected. The LED lamp holder comprises a lampshade and a base. A cavity is formed inside the base. A boss is arranged on the top of the lampshade. A lead drilling hole is formed in the boss. The lampshade is fixedly connected with the base through the boss and enables the cavity to be closed. A main circuit board or a temperature-sensitive component can be placed inside the cavity and separated from a heating source, the main circuit board or the temperature-sensitive component is protected, and the service life of an LED lamp is prolonged.
