The airflow heat dissipation type LED lamp has the beneficial effects that the structure is simple and the design is novel; the problem that the heat dissipation performance of the LED lamp is not good is solved well by the structure under the precondition of not influencing the illumination effect; the occurrence rate of an LED lamp burnout accident is reduced and the service life of the LED lamp is prolonged; the safety of a product is improved.

Description

Airflow radiating formula LED lamp
Technical field
The utility model relates to LED field of illumination lamp technology, specifically, is a kind of airflow radiating formula LED lamp.
Background technology
At present, the development of LED lighting engineering is maked rapid progress, and starts to develop into today from the eighties of last century sixties, pass through the change of several generations, LED illumination market of today has formed certain scale, from upstream product to downstream product, has formed streamlined industrial system.For the LED shot-light of illuminating product, due to advantages such as its energy-saving and environmental protection, accepted gradually by people, so be seen everywhere on the LED shot-light market of all size model.Along with the raising of people's living standard, what people pursued will be more extensive, and LED light fixture has become lighting future developing trend, in known LED technical field of lamps, LED Lamp cup is generally used for that lighting requirement is high, in the environment of high-power illumination, so often the caloric value of LED Lamp cup is large.
And two kinds of heat dissipating methods of the prior art all can not be good solution heat dissipation problem.The first: the outermost at lamp socket arranges fin, the region heat of middle LED fluorescent tube is difficult to distribute, and LED is at high temperature worked, and accelerates light decay, has shortened the service life of LED lamp; The second: on Vehicles Collected from Market, the general aluminium adopting of LED light fixture carries out the LED radiator of extrusion modling and die cast, and due to die-casting material radiator heat-dissipation weak effect, quality is large, and material cost is higher, and light fixture exists certain potential safety hazard; And in process, need to use greater energy consumption equipment, processing charges is high.
Utility model content
For the deficiencies in the prior art, it is good that the purpose of this utility model is to provide a kind of heat dispersion, conveniently installs and uses, and cost is low, the LED lamp of long service life.
For achieving the above object, the utility model is explained a kind of airflow radiating formula LED lamp, comprises the lampshade, Lamp cup, lamp socket and the lamp holder that connect successively, and described lamp cover is contained in described Lamp cup upper end, below described Lamp cup, be fixedly connected with lamp socket, at the described lamp socket lamp holder that has been threaded; Be provided with aluminium base and the driving power being positioned at below described aluminium base in described Lamp cup inside, its key is: be provided with multiple fin at described Lamp cup outer wall, between adjacent two these fin, form heat dissipation channel, this heat dissipation channel runs through the inside and outside wall of described Lamp cup.
A large amount of heat that above-mentioned LED lamp produces in the time of work, is transmitted to heat on fin by heat exchange pattern, and fin fully contacts with Lamp cup simultaneously, and heat is dispelled the heat by Lamp cup fin; Described LED Lamp cup makes thermal current and the outer cold airflow formation of Lamp cup main body convection circulation in Lamp cup, thereby structure, has just reached good radiating and cooling effect, accelerates the flowing velocity of air, improves radiating efficiency, improves LED service life.
One end of described fin is stretched in described Lamp cup, on each described fin, all offers radiating groove, and the air outlet of described radiating groove is positioned at Lamp cup.
The area that radiating groove structure can strengthen the air circulation duct of LED lamp is set, accelerates the exchange of heat, can reach radiating effect better.
The air outlet of described heat dissipation channel is lower than the air outlet of described radiating groove.
The air outlet of heat dissipation channel and radiating groove is set like this, makes cold air and internal heat air form convection current, accelerate the exchange heat of LED lamp inside, accelerated the reduction of temperature, strengthen radiating effect, effectively protected LED lamp and intraware.
Described fin is longitudinally arranged on the outer wall of described Lamp cup along even circumferential.
So more fin can be set and can strengthen the area of air circulation duct, accelerate the flow velocity of air, can reach radiating effect better, make the utlity model has outward appearance elegant in appearance simultaneously.
Described fin adopts aluminum material to make.
Aluminum material radiating effect is better, can protect better the LED lamp in Lamp cup.
Remarkable result of the present utility model is: simple in structure, novel in design, do not affecting illuminating effect, under the prerequisite of reduction Lamp cup material cost, directly well solve the not good problem of LED lamp heat dispersion by structure, reduce the incidence that LED lamp burns out accident, extend the service life of LED lamp, the security that has improved product.
