Description

LED with heat abstractor
Technical field
The present invention relates to lighting technical field, more particularly, to a kind of LED with heat abstractor.
Background technology
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.
The content of the invention
The purpose of the present invention is exactly that the one kind provided to solve the deficiency of prior art is not only simple in structure, Er Qieshe Meter is reasonable, good heat dissipation effect, the LED with heat abstractor of long service life.
The present invention is to realize above-mentioned purpose using following technical solution:A kind of LED with heat abstractor, it is special Levy and be, it includes cell-shell, cell-shell holder assembly, LED light source plate and lamp holder, and lamp holder and cell-shell are individually fixed in cell-shell holder assembly On, cell-shell holder assembly includes being fixedly connected the cell-shell seat outer cover of base and the base connection of cell-shell, cell-shell seat outer cover and base it Between be provided with the heat-dissipating cavity of accommodating radiator fan and power supply, LED light source plate is fixed on base, and air intake wind is set in heat-dissipating cavity Road and exhaust air flue, there is ventilating opening between wind inlet channel and exhaust air flue, radiator fan is arranged on ventilating opening, accelerate into and out of Gas flowing between wind air channel, in cell-shell seat outer cover towards cell-shell end, is provided with several air intakes corresponding with wind inlet channel Hole, exhaust vent corresponding with exhaust air flue makes exhausting to be carried out in the lower end of LED with exhaust, is not limited by installing.
Used as further illustrating for such scheme, the end of cell-shell seat outer cover is provided with end cap, fresh air inlet and exhaust vent point It is not arranged on end cap.
Further, the side of the end cap is provided with annular groove, and the side wall of annular groove is by being fixedly connected the bottom of cell-shell Seat is built-up;Separation baffles are provided with heat-dissipating cavity, gap is continued to employ between the separation baffles and base, form air channel, point The outer rim of baffles is connected and fixed in annular groove.
Further, ventilating opening is arranged on the middle part of separation baffles, and the foreign aid of ventilating opening is provided with fastener will radiate Fan is suspended in the middle part of heat-dissipating cavity.
Further, be provided with a plurality of slotted eye between cell-shell seat outer cover and lamp holder installation position, power supply be arranged on the slotted eye with Between radiator fan, slotted eye is mainly realizes auxiliary heat dissipation or air inlet function, the heat in heat-dissipating cavity is rapidly arranged The external world is put into, the stability of LED is improved.
Further, the exhaust air flue and wind inlet channel are in inside and outside setting, or exhaust air flue and wind inlet channel are in outer Interior setting.
Further, the cross section of the base for being fixedly connected cell-shell is U-shaped, and LED light source plate is fixed on U-shaped base Bottom.
It is of the invention to be using the above-mentioned technical solution beneficial effect to be reached:
The present invention in cell-shell installation end in the form of single-ended air inlet/outlet is realized so that the installation of LED bulb is without limitations; Also, heat-dissipating cavity is divided into and out of air channel with separation baffles so that air-flow can be fully contacted with cell-shell seat outer cover, greatly The big heat exchange area that increased air-flow and cell-shell seat outer cover, improves radiating efficiency;After tested, the LED bulb of more than 100W Can be as lamp affixed to the ceiling purposes.
