Abstract

The invention discloses an LED lamp bulb which comprises a lamp holder, an LED power source, an LED light source, a heat conduction device and a lamp cover. The heat conduction device is mounted in the lamp holder in an interference fit mode, the LED light source is mounted on the heat conduction device, the LED power source is electrically connected with the LED light source and the lamp holder respectively, and the lamp cover is fixedly connected to the lamp holder. The LED lamp bulb has the advantages of being simple and safe in structure, good in heat radiating effect, large in light-emitting area, good in illumination effect and the like.

Description

technical field [0001] The invention relates to a lighting fixture, in particular to an LED light bulb. Background technique [0002] Existing LED light bulbs are usually composed of a lamp holder, lamp holder, radiator, LED light source, LED power supply and lampshade, wherein the LED light source is installed on the top of the metal radiator, and the outer periphery of the metal radiator is wrapped with a plastic lamp holder for insulation. Function, the metal radiator and lampshade are installed on the plastic lamp holder, and the plastic lamp holder is installed on the lamp holder. However, due to the setting of the radiator and the lamp holder, the LED bulb has the defects of complex structure and large structure volume, and limited by the structure of the lamp holder, the lampshade is usually a hemispherical structure, and its light-emitting area is small, resulting in the LED bulb's lighting effect. not ideal. Contents of the invention [0003] Based on this, it i...
