Description
Technical field
The utility model relates to a kind of LED illuminating lamp.
Background technology
Day by day deficient in current resource, under the environmental pollution serious situation, we advocate " low carbon emission reduction, green living ".Traditional illumination power consumption is big, the life-span short, pollution is arranged.Under these circumstances, traditional lighting just must be replaced by new light fixture, and the LED illumination just stands in the breach.LED throw light on changeable unreal, high energy-conservation, life-span length, environmental protection, technology novelty.What LED light fixture technology was just being maked rapid progress is improving, and its luminous efficiency is obtaining surprising breakthrough, and price is also in continuous reduction.A white light LEDs light fixture enters the epoch arrival rapidly of family.But want to replace the performance of conventional lamp high brightness.The LED lighting just must be resolved heat dissipation problem, light efficiency problem and life problems.
Comparing with conventional lamp, the LED lighting will be accomplished high-power, and subject matter is to resolve the heat radiation and the light decay of light source, problems such as dazzle, and this will set about on it is structural and functional.Make it become the cost performance height, the green illumination of a new generation.The energy of input LED, about 20% can convert luminous energy to, and remaining 80% all changes into heat energy, and producing heat is very serious problem, and at first, when temperature raise, luminous intensity can descend, and the life-span also can and then descend.Temperature raises and also can cause radiating wavelength shift, produces aberration, and follows conversion quantum efficiency to reduce, and causes luminous intensity to descend, and material can expand, and product reliability will reduce, and also can reduce service life.Therefore, the light fixture heat radiation is a urgent problem.
Heat radiation has 3 kinds of modes basically, and the one, conduction-type heat radiation, the 2nd, convection type heat radiation, the 3rd, radiant type heat radiation.By three's mathematical formulae as can be seen, dispel the heat main problem points just at area; And because of the heat loss through radiation amount is very little, so topmost radiating mode is aspect conduction and convection current two.So accomplish that high-power LED lighting fixture replaces the traditional lighting light fixture and solving on the heat dissipation problem and will have breakthrough.Among the illumination of LED large-power lamp, except the heat radiation aspect can influence LED the life-span, material of LED own and packing forms also can have influence on the LED life-span, and the thermal resistance after LED itself encapsulation just can have influence on the conduction of LED, could improve the life-span so will accomplish low thermal resistance.The characteristic of LED is directed luminous, and luminous intensity is concentrated, so need secondary optics to change optics, all there is the problem of dazzle in optics in the past in design, so will accomplish to reduce the pollution of dazzle.
The utility model content
At the problems referred to above, the utility model aims to provide a kind of good heat dissipation effect, LED illuminating lamp that volume is little.
For realizing this technical purpose, scheme of the present utility model is: a kind of LED illuminating lamp, comprise lamp holder, be built-in with power panel lampholder shell, be connected the lamp main body on this housing, described lamp main body includes the one group of LED light-emitting component, the aluminium base that light-emitting component is installed that are arranged in this lamp main body one side, is close to the groups of fins to chute gear piece structure of aluminium base, the convection device of the fin heat that can initiatively leave; Described convection device is assemblied in the centre of groups of fins, and the outside importing groups of fins of air from the lamp main body flowed out to the both ends of lamp main body again.
As further improvement, also dispose a radiator cover on the described lamp main body, this cover is provided with the air inlet position corresponding to the position of convection device.
As further improvement, described convection device can be fan.
As further improvement, the bottom opening of described lampholder shell does not have the position of part to cut out sky on the built-in power panel, and the air-flow conducting structure is adopted at the position that the lamp main body combines with lamp socket.
As further improvement, described lamp holder and lampholder shell connecting portion adopt the screw ways of connecting.
As further improvement, all be provided with spreadlight lens on the described LED light-emitting component.
As further improvement, the encapsulation of LED light-emitting component is adopted chip is bundled in structure on the aluminium base.
Technology in the past is unilaterally to dispel the heat by convection current, reaching the certain power area of dissipation needs very big, just volume is just big, so can be restricted when putting into the street lamp shell, weight does not reach the requirement of safety yet, also be subjected to a lot of restrictions in the use, the street lamp of some height just can not be done replacement.
The design of this programme can guarantee that size satisfies various street lamp shells and can use, power and luminous flux have been improved again, the heat radiation aspect has increased more than 5 times, adopt chip directly to be bundled in the pattern of aluminum-based circuit board, can reduce thermal resistance, reduce heat conducting interface, reduced the operating temperature of chip, can hang down more than 10 degree than traditional method led chip operating temperature.Present technique can ensure the feature of long life of LED light fixture, and is also very flexible in use, can be used in road lighting, the sub-district illumination, and industrial lights etc. need the place of highlighted illumination, have improved utilization rate greatly.
