Description
Technical field
The present invention relates to a kind of semiconductor illumination device, particularly a kind of high-power LED illuminating device with comprehensive heat sinking function.
Background technology
High-power LED illuminating device has good electricity-saving effect, existing countries in the world government all under vigorously promote the use the LED lighting device, but, core component as the LED lighting device, the LED luminescence chip, it is a kind of light emitting semiconductor device, environment temperature to its work is very responsive, high temperature is very big to luminous efficiency, service life, the reliability effect of LED luminescence chip, when being in unfavorable hot environment, the LED luminescence chip works, LED luminescence chip not only luminous efficiency significantly descends, and is easy to damage inefficacy.Therefore, the heat dissipation design of high-power LED illuminating device is very crucial for high-power LED illuminating device.
The radiating mode of traditional LED lighting device can be divided into two kinds substantially, and a kind of is active radiating mode and passive radiating mode.Active radiating mode is exactly the air-cooled radiator that utilizes as be with fan, liquid stream refrigeration radiator, the radiator that has a Pa Er card electron cooling element wait to be realized, this high-power LED illuminating device, since extra increase power unit, be used for dispelling the heat to the LED lighting device, make the electricity saving performance of LED lighting device have a greatly reduced quality, in addition, because the stability problem of the other heat-sink unit that increases, can not determine and the job stability that makes the LED lighting device becomes, therefore, only very necessary, active radiating mode does not generally adopt.Another kind is passive radiating mode, and it is to utilize the radiating element of the radiator of the groove have a series of different shapes or radiating fin as the LED lighting device, also is maximum radiating mode that existing LED lighting device adopts.Common passive heatsink is that the LED luminescence chip is distributed on the passive heatsink bottom surface mostly, is provided with groove or radiating fin on the bottom surface with respect to the side that the LED luminescence chip is set of passive heatsink, and whole passive heatsink all is made of metal.Described metal all is metals of high heat conductance, as aluminum or aluminum alloy, copper or copper alloy, copper core aluminium etc.There are two problems in this passive heatsink, and one is that this heatsink weight is heavy, and volume is big, and is relative with the incandescent lamp of traditional equal-wattage, and its volume is more than a times of incandescent lamp, and its weight is more than 10 times of incandescent lamp; The 2nd, when the LED lighting device was worked in static air, because the air in the groove is static basically between fin, its radiating effect was had a greatly reduced quality.
In order to solve above-mentioned two problems, it is moderate to seek a kind of weight and volume, and the LED lighting device that radiating effect is good, Chinese patent literature CN101788112 discloses a kind of three-dimensional heat dissipation high-power LED illumination device, it is more than one LED luminescence chip to be arranged on the bottom surface of passive heatsink of with groove or radiating fin constitute an independent illuminator, many outer independent luminaire spacing certain distances are fixedlyed connected with connecting plate by the other end of passive heatsink, but constitute the three-dimensional heat dissipation structure of a ventilation on all sides.This three-dimensional heat dissipation high-power LED illumination device and traditional passive radiating LED illuminating device are having bigger improvement really aspect weight, volume and the radiating effect, but this three-dimensional heat dissipation high-power LED illumination device is also having improvable aspect aspect weight, volume and the radiating effect.
Summary of the invention
Technical problem to be solved by this invention provides the high-power LED illuminating device of the comprehensive heat radiation that a kind of radiating effect is better, weight is lighter and volume is littler.
Basic ideas of the present invention are the strip LED fluorescent tubes that the LED lighting unit are designed to not have source heat-dissipating, the strip LED fluorescent tube of no source heat-dissipating is clipped in fixed disk and coils between the circumference admittedly down, and will go up fixed disk with screw rod and fixedly connected with lower fixed disk, like this, the strip LED fluorescent tube of several no source heat-dissipatings forms a circle and constitutes an air channel, heat when the generation of the strip LED of no source heat-dissipating fluorescent tube, heat is from bottom to top formed the runner of a nature from the air channel and is discharged from, like this, when the present invention had both made is to be in when using in the static air, the present invention itself also can form a heat loss through convection circulating current, reaches the better purpose of radiating effect; Because good heat dissipation effect, it is littler that passive heatsink of the present invention like this can be done, and volume of the present invention also can be done littler.
Concrete technical scheme of the present invention is: design a kind of high-power LED illuminating device of comprehensive heat radiation, comprise the upward cover and the led driver of band lamp holder; Also comprise fixed disk, on described the circumference of the bottom surface of fixed disk be provided with plural on locating hole, lower fixed disk, the circumference of the upper bottom surface of described lower fixed disk be provided with last fixed disk on the following locating hole that equates of the quantity of locating hole, be provided with the strip LED fluorescent tube of the no source heat-dissipating that equates with locating hole quantity on described between location-plate and the following location-plate, the strip LED fluorescent tube upper end of described no source heat-dissipating is inserted in described going up in the locating hole, its lower end is inserted in the described locating hole down, the described fixed disk of going up is fixedlyed connected by screw rod with described lower fixed disk, and the strip LED fluorescent tube that will not have a source heat-dissipating be clipped in described between fixed disk and the described lower fixed disk; The described fixed disk of going up is fixedly connected on described going up on the bottom surface of covering.
As improvement of the present invention, the strip LED fluorescent tube of described no source heat-dissipating comprises half slot shape translucent cover and semicircle strip radiator, described half slot shape translucent cover and semicircle strip radiator are cylindric by one of card article interlocking formation, be provided with plurality of LEDs lamp pearl on the inner plane of described semicircle strip radiator, described LED lamp pearl provides power supply by described led driver.
As to further improvement of the present invention, the described semicircle strip radiator back side is provided with groove or radiating fin.
As further improving of the present invention, described led driver is arranged on described going up in the cover.
As further improving to of the present invention, on the bottom surface of described lower fixed disk, also be provided with LED illuminated panel down, on the bottom surface of described LED illuminated panel down, be provided with several lower wall LED lamp pearls.
As further improving of the present invention, also fastening on described lower fixed disk has following translucent cover.
