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 bulb

Technical field

The present invention relates to a kind of LED bulb.

Background technology

As everyone knows, the LED light-emitting component can produce a large amount of heats when work.The LED light-emitting component is applied to the bulb lighting field,, will has influence on the service life of LED bulb product widely as not solving the heat dissipation problem of LED light-emitting component.Because the normal working temperature of LED light-emitting component generally is about 50 degree, in the course of the work, every again intensification 10 degree of LED, will shorten 50% its service life.

Yet, the heat dissipation that present LED bulb product is habitual, mainly contain two kinds: a kind of is thermal convection current formula radiator structure, promptly adopts a miniature radiator fan is set on the LED bulb, by the air flow property in the radiator fan quickening LED bulb, reach the purpose of cooling.The structure of this radiating mode is comparatively complicated, limit morely, and ten minutes is unfavorable for the design of LED bulb aspect style and the control of volume aspect; And equal about 5,000 to 10,000 hours of the electrical machinery life of radiator fan, and about about 100,000 hours of the life-span of LED light-emitting component is very asymmetric, is seriously restricting the true lifetime of LED bulb.Thereby affect applying of LED bulb to a great extent, general less using.Another kind is hot conduction-type radiator structure, promptly adopts the aluminium alloy radiator structure is set on the lamp bracket of LED light-emitting component, conducts by the heat that aluminium alloy is accelerated between LED light-emitting component and the outside air, reaches the effect of cooling.This mode is the main radiating mode of current LED bulb, compare with employing thermal convection current formula radiator structure, though reducing aspect structural complexity and the volume, popularize popular, small and exquisite, the reliable quality advantage of volume but can't reach the simple in structure, with low cost, easy of conventional bulb, thereby still greatly affect applying of LED bulb product.

Summary of the invention

The objective of the invention is to solve above-mentioned deficiency, a kind of perfect heat-dissipating, simple in structure is provided, without any influence, help bulb-shaped and structural design to the structure of bulb and volume, and be beneficial to and reduce the LED bulb that cost of goods manufactured and product promotion are used.

Technical scheme of the present invention is achieved in that

A kind of LED bulb, comprise lamp holder, cell-shell, lamp bracket and be installed on LED light-emitting component on the lamp bracket, its characteristics are that the surface of described lamp bracket is provided with the reactive metal zirconium coating, this reactive metal zirconium coating work adstante febre gives out the cation hot gas, be filled with the anion nitrogen in the described cell-shell, chemical neutralization reaction takes place by the cation hot gas with the generation of reactive metal zirconium coating and realizes whole bulb cooling effect in this anion nitrogen.

Above-mentioned lamp bracket is made of multilayer square front lamp frame component closed assembly, and the side is separately installed with the LED light-emitting component around the end face of this lamp bracket and each the lamp bracket assembly.

Above-mentioned lamp bracket is fixed on the glass stem that is provided with in the cell-shell, and this glass stem is affixed with the cell-shell seat that the cell-shell bottom is provided with; And also be respectively equipped with resistive element at the left and right side that is positioned at glass stem, wherein an end of a resistive element is electrically connected by the wherein wiring pin that lead and LED light-emitting component are provided with, and the other end of this resistive element is connected on the wherein conductive electrode that lamp holder is provided with by lead; One end of another resistive element is electrically connected by another wiring pin that lead and LED light-emitting component are provided with, and the other end of this another resistive element is connected on another conductive electrode that lamp holder is provided with by lead.

Technical characterstic of the present invention:

Be provided with the work adstante febre by the lamp bracket surface in cell-shell and can produce the reactive metal zirconium coating of cation hot gas and the mode that in cell-shell, is filled with the high-pressure anionic nitrogen, make LED bulb product when work, the work calories that the LED light-emitting component produces, pass to lamp bracket, activate the reactive metal zirconium coating on lamp bracket surface by the lamp bracket heating, radiation gives out the hot gas of positive charged ions in the atom, chemical neutralization reaction just in time takes place with the high-pressure anionic nitrogen that fills in cell-shell in this hot gas, balance out the heat that the LED light-emitting component produces, thereby realize the effect of LED bulb cooling, play the reliability of assurance LED bulb and the effect in service life.And, owing to lower the temperature by the chemical neutralization reaction mode of this cation hot gas, anion nitrogen, can not constitute any restriction to bulb-shaped, volume and structure, thereby can make things convenient for the design and the making of LED bulb widely, help reducing the manufacturing cost of LED bulb and applying of this series products.

The present invention is further illustrated below in conjunction with accompanying drawing:
