Description

LED with heat abstractor
Technical field
Lighting technical field is the utility model is related to, more particularly, to a kind of LED with heat abstractor.
Background technology
LED=Light Emitting Diode, light emitting diode, it is that a kind of can 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 For main flow, while energy-saving, health, art up and hommization illumination development trend are fully demonstrated, turn into 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 producing, and substitute products are electronic energy-saving lamps therewith, 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 very high ratio, wasted to reduce, LED illumination manufacturer, which must develop, meets 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 Distribution curve flux is substantially convergent with the spot light of incandescent lamp.
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 can all set up one piece of very big heat radiating metal in cap part, the LED bulb of part can also set scattered Hot fin is to improve radiating efficiency, or even fan cooling structure can be set up in lamp holder, as Chinese Patent Application No. is CN201120240722.6, a kind of entitled radiator structure of LED lamp of utility model, including LED body and power supply, it is special Sign is:The lamp body is fixedly connected on fan set bottom, and the fan set is built-in with power supply and blower, the top of fan set 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 convection current up and down, the heat inside accelerated release in vitro, in order that solving the low technical problem of prior art radiating efficiency.But It can not be used for Ceiling light lighting use, and its reason is that the air of starting fan is upper and lower convection current, and the design of Ceiling light It is that more than ceiling position is typically all sealed set, usually no air flow, radiating effect is inherently bad, If LED lamp uses the form of lower air intake, then, heat will be taken to inside ceiling, cause temperature rapidly to rise, directly Other light fixtures can be impacted;If LED lamp uses the form of upper air inlet, due to the rarefaction of air in ceiling, LED The fan work of tool will damage for a period of time, can not implement refrigerating function, be only suitable for using peak power at present as 60-70W 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 photographs Bright LED illumination lamp.
