Abstract

The invention discloses an LED bulb. The LED bulb comprises an LED light source plate, and a bulb shell arranged above the LED light source plate, wherein a graphene layer is arranged on the inner wall of the bulb shell, and is thermally connected with the LED light source plate to transfer heat generated by the LED light source plate to other parts of the bulb shell. As the graphene layer is arranged on the inner wall of the bulb shell, and is thermally connected with the LED light source plate, the heat generated by the LED light source plate can be quickly dispersed to the external or transferred to other parts through the bulb shell. And as the bulb shell has a larger surface area, the heat dissipation speed is largely accelerated; and the LED bulb has the advantages of good heat dissipation effect and simple structure.

Description

technical field [0001] The invention relates to an LED lighting fixture, in particular to an LED light bulb. Background technique [0002] LED light sources have the advantages of high luminous efficiency, low heat generation, power saving and long life, so their applications are becoming more and more extensive. LED lamps will gradually replace traditional lighting fixtures such as incandescent lamps and halogen lamps. However, with the increase in the number of LEDs in the LED bulb lamp, as well as the increase in power and brightness, the heat generated by the LED lamp during operation has risen sharply. Therefore, how to improve the heat dissipation effect of the LED bulb lamp has become a major problem in the technology of the LED bulb lamp. Contents of the invention [0003] In view of this, it is necessary to provide an LED light bulb with good heat dissipation effect and simple structure. [0004] An LED light bulb, comprising an LED light source plate and a lig...
