When the LED lamp is used to throw light on,, be directly fixed on the LED lamp in the column type heat carrier, should between LED lamp and column type heat carrier, apply one deck heat-conducting silicone grease simultaneously, so be transmitted to the heat of LED wick sheet rapidly in the column type heat carrier in order to reduce one deck thermal resistance.Sometimes for the designing requirement and the structural rationalization of the different demands of LED illuminating product, first perforate (hollow) in the column type heat carrier, the LED lamp is fixed on the heat transfer core, fills up the heat transfer core in the column type heat carrier then.
In order to increase the surface area of this radiator, on heat transfer sheet one side, be connected with fin or extend into radiating shell to fin.Between a pair of heat transfer sheet, also can increase fin or not increase fin.In order to improve the smokestack suction effect, this radiating shell directly is connected with corresponding another radiating shell and has formed the enclosed type housing, can play the effect of convective cover.
The heat of column type heat carrier distributes in air through heat transfer sheet and the fin around it.When its fin was arranged with radiation mode, as if relatively shorter narrow near the fin of column type heat carrier and the distance between another fin, so the fin root produced hot short circuit phenomenon, promptly lose convection function.So, arrange with parallel mode at fin on heat transfer sheet one side and the fin on the column type heat carrier, improve radiating effect.Also can parallel or not parallel mode arrange with fin when as the case may be, fin becomes radiating shell.The arrangement of heat transfer sheet and fin is uneven.
In LED lamp diabatic process, in order to reduce thermal resistance, be secured in the heat transfer core in the column type heat carrier with screw thread or the rivet mode jam-pack that closely cooperates.
LED lamp specification kind of light fixture when practical application is a lot, so can do circular, square, polygonal or rectangle at the peripheral shape of LED lamp radiator, so that the light fixture of different size can be selected suitable shape for use, improves radiating effect.
The invention has the beneficial effects as follows; Owing on column type heat carrier outside, be provided with a pair of heat transfer sheet and radiating shell thereof, the heat in the column type heat carrier conducts rapidly through a pair of heat transfer sheet to be given on radiating shell or the fin, passes through cross-ventilation again; Be dispersed into heat in the air; Assurance LED lamp is worked in the temperature range that allows, and prevents light decay, prolongs the life-span of LED lamp.Secondly advantage is, LED lamp radiator is to adopt the good aluminium material of thermal conductivity, is integral with extrusion process; And can cut use, compact conformation reduces cost; Increase the specification kind, can satisfy multiple LED lightings such as exploitation shot-light, bulb lamp, ceiling embedded lamp, suspension lamp.
