LED with heat abstractor
The present invention relates to lighting technical field, more particularly, to a kind of LED with heat abstractor.
LED=Light Emitting Diode, light emitting diode is a kind of can to convert electrical energy into consolidating for visible ray
The semiconductor devices of state, electricity directly can be converted into light by it.The room Design of Luminaires of 21 century is designed with led lighting bulbs
It is main flow, while energy-saving, health, art up and hommization illumination development trend are fully demonstrated, as room light text
That changes is leading.Conventional incandescent (tengsten lamp) power consumption is high, short life, gradually each under the nervous overall situation of global resources
Government of state forbids production, and substitute products are electronic energy-saving lamps therewith, and although electronic energy-saving lamp improves energy-saving effect, but due to making
With the heavy metal element of many pollution environment, the main trend of environmental protection is run counter to again.With the high speed development of LED technology
LED illumination is increasingly becoming the only choosing of novel green illumination.Because incandescent lamp and electronic energy-saving lamp are in the routine use of people
In still in occupation of ratio very high, in order to reduce waste, LED illumination manufacturer must develop and meet existing interface and people
The LED illumination product of use habit so that people can make in the case where that need not change former conventional lamp pedestal and circuit
With the LED illumination product of a new generation.Then LEDbulb lamp is just arisen at the historic moment.LEDbulb lamp employs existing interface mode,
That is screw socket (E26 E27 E14 etc.), socket mode (B22 etc.), or even imitated incandescent lamp to meet the use habit of people
The profile of bubble.Based on the principle of luminosity of LED one-way, designer has done change on fitting structure and has caused LEDbulb lamp
Spot light of the distribution curve flux substantially with incandescent lamp is convergent.
At present, LED illumination lamp is main or based on large power white light LED list lamp, because its caloric value is big, in order to avoid
Electronic component is burnt, typically all one piece of very big heat radiating metal can be set up in cap part, the LED bulb of part can also set scattered
Hot fin is improving radiating efficiency, or even fan cooling structure can be set up in lamp holder, and such as Chinese Patent Application No. is
CN201120240722.6, a kind of entitled radiator structure of LED lamp, including LED body and power supply, its feature exist
In：The lamp body is fixedly connected on fan set bottom, and the fan set is built-in with power supply and blower, and the top of fan set is provided with
Cover.The program is built between lamp socket and the lamp bead circuit board module of heating using aerofoil fan, and starting fan causes air
Upper and lower convection current, the heat inside accelerated release in vitro, in order that solving the low technical problem of prior art radiating efficiency.But, it is simultaneously
Ceiling light lighting use is cannot be used for, its reason is that the air of starting fan is upper and lower convection current, and the design of Ceiling light is day
Position more than card is typically all what sealing was set, usually no air flow, and radiating effect is inherently bad, if
LED lamp is in the form of lower air intake, then, heat will be taken to inside ceiling, cause temperature rapidly to rise, directly meeting
Other light fixtures are impacted；If LED lamp is in the form of upper air inlet, due to the rarefaction of air in ceiling, LED lamp
Fan work will damage for a period of time, it is impossible to implement refrigerating function, it is 60-70W's to be only suitable for using peak power at present
LED bulb.For this reason, it is necessary to develop a kind of more rational with fan heat structure and can be suitably used for various illuminations
LED illumination lamp.
