Abstract
The invention discloses an LED lamp holder. The luminous efficiency of an LED reduces along with the increase of the temperature of the LED, and therefore the heat dissipation of the LED is quite important. If heat generated can not be dissipated in time, the temperature around a luminous unit will be increased, and therefore aging of a chip and packaging resin is accelerated, welding spot melting might be caused to further result in the invalidation of the chip, and then the service life and the luminous performance of the LED are affected. The LED lamp holder comprises a lampshade and a base, wherein a cavity is formed in the base, a boss is arranged on the top of the lampshade, a wire leading hole is formed in the boss, the lampshade is fixedly connected with the base through the boss and seals the cavity, a main circuit board or a thermosensitive component can be placed in the cavity to be separated from a heating source, and therefore the main circuit board or the thermosensitive component is protected, and the service life of an LED lamp is prolonged.
Description
[technical field]
The present invention relates to a kind of lamp holder, especially a kind of LED lamp holder.
[background technology]
