Light-emitting diode (LED) lamp bulb

Abstract

The invention provides a light-emitting diode (LED) lamp bulb. The lamp bulb comprises a bulb holder, a lamp cup and a bulb shell, wherein the lamp cup is provided an inner step and a radiation device; the radiation device is composed of radiating holes; the bulb shell is fixed at one end of the lamp cup, and an insulation connecting piece is arranged between the other end of the lamp cup and thebulb holder; a vent hole is arranged in the center of the insulation connecting piece; and a tightening cap is arranged between the insulation connecting piece and the lamp cup. The LED lamp bulb further comprises an LED lamp board, a drive circuit component and fixing devices, wherein the drive circuit component is arranged between the LED lamp board and the insulation connecting piece; and the fixing devices are fixed between the LED lamp board and the drive circuit component and between the drive circuit component and the insulation connecting piece. The LED lamp bulb has the characteristics of safety, reliability, high stability, nice appearance and good radiation effect, and is suitable for general consumers.

Description

technical field [0001] The invention relates to an LED light bulb, in particular to an LED light bulb with safety, reliability, high stability and good heat dissipation effect. Background technique [0002] Traditional incandescent light bulbs have low illuminance, dim light, and are not energy efficient. After the incandescent light bulb, the fluorescent light bulb appeared. Although it is energy-saving and bright, it is not environmentally friendly due to the large amount of fluorescent powder used. At present, there are more energy-saving and environmentally friendly LED light sources, and LED light bulbs are produced thereupon. [0003] Existing LED light bulbs generally have complex structures, and the fixing of the LED light board and the driving power board is fixed by gluing with insulating tape. However, the LEDs fixed by gluing The lamp board and the driving power supply assembly are easy to loosen and are not fixed stably, so that the LED lamp board and the driv...

AI Technical Summary

Problems solved by technology

[0003] Existing LED light bulbs generally have complex structures, and the fixing of the LED light board and the driving power board is fixed by gluing with insulating tape. However, the LEDs fixed by gluing The lamp board and the driving power supply assembly are easy to loosen and are not fixed stably, so that the LED lamp board and the driving power board fall over and collide with the lamp cup, which is easy to damage the lamp cup, so there are the following defects: 1. The fixation between the LED bulb and the drive circuit assembly is unstable; 2. The lamp cup is made of glass or plastic, and the heat dissipation effect of glass and plastic is not good, which cannot meet the high heat dissipation of high-power LEDs. requirements, thus affecting the reliability of its use
