LED bulb

Abstract

The invention relates to an LED bulb which comprises a lamp cap, a bulb shell, a lamp holder and an LED luminous element arranged on the lamp holder, and is characterized in that the surface of the lamp holder is provided with an active metal zirconium coating; when in heating, the active metal zirconium coating emits cation hot gas; anion nitrogen gas is fed into the bulb shell; and the anion nitrogen gas realizes the cooling effect of the whole bulb by having chemical neutralization reaction with the cation hot gas produced by the active metal zirconium coating. When the LED bulb works, the working heat produced by the LED luminous element is transmitted to the lamp holder, the lamp holder heats and activates the active metal zirconium coating on the surface of the lamp holder, and radiates and emits the hot gas with cation in atoms; the hot gas rightly has chemical neutralization reaction with the high-voltage anion nitrogen gas fed into the bulb shell, to offset the heat produced by the LED luminous element, realize the cooling effect of the LED bulb, and play the role of ensuring the reliability and the service life of the LED bulb.

Description

A kind of LED light bulb technical field The invention relates to an LED light bulb. Background technique As we all know, LED light-emitting components will generate a lot of heat when they work. Applying LED light-emitting elements to the field of light bulb lighting, if the heat dissipation problem of LED light-emitting elements is not solved, the service life of LED light bulb products will be greatly affected. Because the normal working temperature of LED light-emitting elements is generally about 50 degrees, during the working process, every time the LED heats up by 10 degrees, its service life will be shortened by 50%. However, there are two main heat dissipation methods commonly used in current LED light bulb products: one is the thermal convection heat dissipation structure, that is, a miniature heat dissipation fan is installed on the LED light bulb, and the air flow in the LED light bulb is accelerated through the heat dissipation fan. , to achieve the purpose...

AI Technical Summary

Problems solved by technology

This method is the main heat dissipation method of LED bulbs today. Compared with the heat convection heat dissipation structure, although the structure complexity and volume are reduced, it still cannot achieve the simple structure, low cost, and easy popularization of traditional light bulbs. The advantages of small size and reliable quality have greatly affected the promotion and application of LED bulb products.
