LED (light-emitting diode) light bulb

Abstract

The invention relates to an LED (light-emitting diode) light bulb which comprises a light source module, a power module, a radiator, an insulating sleeve, a lamp hood and a lamp holder, wherein the insulating sleeve is an irregular round pipe; an annular flange is arranged on the outer surface of the insulating sleeve; the power module is arranged inside a center hole of the insulating sleeve; the lamp holder is fixed at the lower part of the flange on the outer surface of the insulating sleeve while the radiator is fixed at the upper part of the flange on the outer surface of the insulating sleeve; the light source module is arranged on a disc plane formed by the upper end of the radiator sinking inwards; and the light source module and an insulating element are fixed and locked while the lamp hood is locked inside a radial annular groove at the upper brim of the radiator. The LED (light-emitting diode) light bulb is simple in structure, convenient to install, and good in radiating effect, the service life of the bulb is greatly prolonged, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a high-performance LED light bulb with a special structure, belonging to the technical field of semiconductor lighting. Background technique [0002] LED bulbs, also known as LED ball bulbs, are the most produced and exported LED lighting products in my country's LED lights. The structure and shape of LED light bulbs are basically similar to domestic and foreign products, and their appearance is similar to ordinary lighting incandescent lamps. However, the structure of LED bulbs is much more complicated than that of ordinary lighting incandescent lamps. It is mainly composed of light source modules, power modules, radiators (also known as lamp bodies), insulating sleeves (body), lampshades, lamp holders, connectors and other components. At present, although the main parts (modules and assemblies) of LED bulbs in my country have been professionally produced by enterprises, a complete industrial chain has been formed. However, ...

AI Technical Summary

Problems solved by technology

However, since the lampshade is sealed and connected with the lamp body by glue, neither convective heat transfer can be formed, so the heat dissipation effect is poor.

[0008] 2. Large light decay and short actual life

[0009] Due to the high operating temperature of LED lights, the aging of phosphor powder is accelerated, the light decay is increased, and the life is shortened. The actual life of LED bulbs is far lower than its theoretical life.

[0010] 3. There are many interfaces, and the assembly and connection are cumbersome

The interface is not uniform, not interchangeable, and the connection is cumbersome

[0012] 4. Low labor productivity and high cost

[0013] Due to manual assembly and crowd tactics, the production efficiency is low

LED lights need a good heat dissipation system, so the cost is high

[0014] 5. At present, the structure of LED lights is difficult to realize automatic production
