Problems solved by technology

[0003] In addition, LED bulbs are composed of many materials, such as aluminum and plastic. When they heat up and contract, their shrinkage rates are also different because of their different materials. A slight deformation will cause extrusion stress between the parts. , there is deformation and damage

Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] The up and down direction of the present invention is based on the placement state of the bulb during normal use, that is, the direction where the threaded head is located is up, and the direction where the bulb cover is located is down;

[0028] Such as Figure 1 to Figure 3 As shown, an LED light bulb includes a lampshade 3, a plastic shell 2 and a lamp cap 1. The lampshade 3 also includes a drive control board 5 and a light source board 4 disposed in a cavity formed by the lampshade 3 and the plastic shell 2. And the heat dissipation mechanism, the heat dissipation mechanism includes a heat dissipation element 6, the heat dissipation element 6 has a first connection part 61 and a second connection part 62 (thickness of the first connection part 61 and the second connection part 62 is 1.3 mm), the first connection part 61 It...

Abstract

The invention relates to an LED bulb. The bulb comprises a lampshade, a plastic shell and a lamp holder. The lampshade further comprises a drive control panel, a light source panel and a heat dissipation mechanism which are arranged in a cavity defined by the lampshade and the plastic shell. The heat dissipation mechanism comprises a heat dissipation piece. The heat dissipation piece is provided with a first connecting part and a second connecting part. The first connecting part is in an annular disc shape. The lower side face of the first connecting part is in butt joint with the light sourcepanel. The second connecting part is cylindrical. The outer circumferential face of the second connecting part is in butt joint with the plastic shell. The drive control panel is arranged on the inner circumferential side of the cylindrical second connecting part. According to the LED bulb, the LED bulb is novel in structural design. The structural design of the heat dissipation piece is simple and ingenious, and the heat dissipation effect of the heat dissipation piece is extremely good. In addition, through the arrangement of the overall structure of the LED bulb, the installation and assembly procedures (the heat dissipation piece and the plastic shell are integrally formed, installation is not needed) are reduced, and therefore the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to an LED light bulb. Background technique [0002] When working, poor heat dissipation will have a series of adverse effects on the use of LED lights. For example, LED light source converts electrical energy into light source, but not all electrical energy can be converted into light source, which must abide by the law of conservation. If it is excess electric energy, it may be converted into heat energy. For LED lights, heat dissipation is the most important thing. If the heat dissipation is not good, it will have a series of adverse effects on the use of LED lights. If the LED light source is overheated and the heat cannot be removed, these materials will be repeatedly oxidized by high temperature, resulting in a decrease in the quality of the LED light source. In addition, if the heat dissipation structure of LED lamps is not designed properly, it will not be able to quickly remove excess heat, and the temperature of the LED...
