Abstract
The invention discloses LED high brightness bulb, comprise lampshade, LED diode, wiring board, fin, back seat, the LED diode is welded on the described wiring board, and the fin rear portion is equipped with ventilating fan.The present invention is owing to adopt technique scheme, LED high brightness bulb is equipped with ventilating fan at the fin rear portion, and the heat of Chan Shenging can in time distribute in the course of the work, bulb temperature is remained on be no more than 40 ℃, improved its service life greatly, made product energy-saving durable more like this.
Description
Technical field
The present invention relates to LED high brightness bulb.
Background technology
The LED lamp is owing to its light efficiency height, and radiationless and low in power consumption more and more has been subjected to people's welcome since it comes out.Along with progress of science and technology, the LED lamp has also constantly obtained innovation and development, and its advantage of comparing other lighting systems is also more and more outstanding.Can predict that the spreading speed of LED lamp can constantly be accelerated.Yet the LED lamp but has a problem perplexing its producer and user in its evolution all the time, and that is exactly its heat dissipation problem.If untimely the distributing of heat that produces in the LED lamp course of work, its life-span can be subjected to very big influence.Existing LED heat radiation generally adopts the fin mode to dispel the heat.Though also can play certain thermolysis, its radiating effect is not ideal enough.
Summary of the invention
Technical problem to be solved by this invention provides a kind of LED high brightness bulb with excellent heat dispersion performance, can improve greatly its service life.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: LED high brightness bulb, comprise lampshade, LED diode, wiring board, fin, back seat, and described LED diode is welded on the described wiring board, and described fin rear portion is equipped with ventilating fan.
Described lampshade and described back seat clamping.
Described fin is an aluminum alloy heat sink.
The present invention is owing to adopt technique scheme, LED high brightness bulb is equipped with ventilating fan at the fin rear portion, and the heat of Chan Shenging can in time distribute in the course of the work, bulb temperature is remained on be no more than 40 ℃, improved its service life greatly, made product energy-saving durable more like this.
