Abstract

The invention discloses an LED lamp bulb. The LED lamp bulb comprises a lamp holder (2), a radiator (4) and a lampshade (6). The lamp holder (2) is located at the top of the radiator (4). The lampshade (6) is located at the bottom of the radiator (4). A round PCB (8) is arranged on the bottom wall of the radiator (4). A plurality of LED wafers are arranged on the PCB (8) at equal intervals. The LED lamp bulb is characterized in that the lampshade (6) and the radiator (4) are in threaded fit connection; a circle of protrusion (10) is arranged on the inner wall of the lampshade (6) in a surrounding manner, and the outer diameter of the protrusion (10) is the same as the diameter of the PCB (8); and after the lampshade (6) is connected with the radiator, the protrusion (10) can press the PCB (8) on the bottom wall of the radiator (4) in an abutting manner. The LED lamp bulb has the beneficial effects of being convenient to maintain and assemble.

Description

technical field [0001] The invention relates to a light bulb, in particular to an LED light bulb. Background technique [0002] At present, as a home lighting fixture used to replace tungsten lamps and fluorescent lamps, LED lamps have the advantages of low energy consumption, high light efficiency, no mercury, no radiation pollution, and renewable materials. Today, it is becoming more and more popular with consumers. As a kind of LED lamp, LED light bulb usually includes a lamp cap, a radiator and a lampshade, wherein the lamp cap is located on the top of the radiator, the lampshade is located on the bottom of the radiator, and the lampshade is often fixedly connected to the radiator by glue, although, This method of using glue to paste the radiator and the lampshade has the advantage of being simple to manufacture. However, when a certain LED light source inside the lampshade needs to be replaced or repaired, the lampshade can only be removed by destroying the lampshade. ...
