Abstract

The invention provides a radiator for a super high power LED (light emitting diode) single light source illuminating light. In the radiator, a single-color or multi-color LED chip is used, the surface is sealed with silica through combination of serial connection and parallel connection, a metal substrate is used as a heat sink, and a condenser lens is added. The heat of a certain surface condensing point can be quickly conducted to the peripheral surface layer of a vacuum cavity at a conduction speed 100 times of that of pure copper by adding a proper amount of working liquid into the vacuum cavity, and the heat of the super high power LED single light source illuminating light can be quickly radiated by virtue of a plurality of heat-radiation fins on the peripheral surface layer of the vacuum cavity and the enough heat-radiating surface on the surface of the light, so that the aim of quick heat radiation can be achieved.

Description

The radiator of single light source of a kind of super-high-power LED

Technical field.

The present invention relates to the radiator of single light source of a kind of super-high-power LED, technical background

Light emitting diode, be called for short LED, it is little to have volume, energy consumption is low, high brightness, advantages such as low pressure operation, be widely used and all trades and professions field, adopt the LED semiconductor solid-state optical source to come replace incandescent and fluorescent lamp etc., become trend, but, LED is because of being subjected to the restriction of self-characteristic, the operating temperature height can cause the light sorrow to subtract seriously, influence service life, and the illuminating lamp of single super-high-power LED light source, more must have the better radiator of thermal diffusivity, the heat that is produced when promptly led chip being worked distributes, the radiator of existing single high-power combination LED illuminating lamp adopts usually several led chip connection in series-parallel combinations, dense arrangement light source together is fixed on the aluminium alloy plate again, and is by aluminium alloy plate natural heat dissipation, far relatively by led chip end-to-edge distance like this, because led chip is intensive more concentrated together, the heat that is gathered is difficult to quick derivation, and work can make the temperature of led chip surpass the interior temperature of its scope in service life for a long time, thereby has influenced the illuminating effect and the service life of led chip.

Summary of the invention

Problem to be solved by this invention is to overcome the above-mentioned defective of prior art, and the radiator of good single the light source of a kind of super-high-power LED of a kind of thermal diffusivity is provided.

The technical solution adopted in the present invention is

Aluminium alloy with perfect heat-dissipating is a raw material, through large-scale aluminium extrusion, by necessary requirement, be formulated to one and have vacuum cavity, the fin heat dissipation channel, the light fixture radiating surface is an one, and be provided with multi-faceted, the radiator of single the light source of a kind of super-high-power LED of diversified led light source pedestal row location, utilize and add an amount of working solution in the vacuum cavity, can conduct the principle of heat fast, heat on the described led light source pedestal row location of being set up on the vacuum cavity promptly is transmitted to the vacuum cavity surrounded surface has many fin, the radiating surface of heat dissipation channel and light fixture, the heat that is produced during the work of the heat sink upward led chip of pedestal promptly looses to derive led chip is remained in the safe and reliable heat rating, solves above many disadvantages.

The radiator of single light source of above-mentioned described a kind of super-high-power LED, wherein radiator is exactly a light fixture, add an amount of working solution in the vacuum cavity in the described radiator, the principle that can conduct heat fast is: a large amount of heat that produces was when led light source was worked on set position, when this end points is heated, this heat can be starting working about near 30 degree of the working solution fluid vaporization the body wall, the vapour pressure of heating end can raise and made steam move and produce steam flow toward the gas end that coagulates of the air pressure end of than this moment, steam borrows capillary force to be back to evaporation ends and to finish a circulation coagulating end cooling release heat and condensing into liquid.

Conduct heat by vacuum cavity, still do not alleviated the weight of light fixture self, the more important thing is promptly to shift the big calorimetric that an end points produces and be diffused on the whole vacuum cavity surface, its heat transfer rate will be 100 times of copper, 200 times of aluminium, like this can the heat on the led chip with the fastest VELOCITY DIFFUSION around the whole vacuum cavity on the outer surface, the radiator with this technology is made can reach very effective result to a kind of super-high-power LED light illumination lamp.

The radiator of single light illumination lamp of above-mentioned a kind of super-high-power LED, the described aluminium alloy extrusions of formulating by necessary requirement, it is a semicylinder, the baseplane pars intermedia is used for installing led light source, described circular arc type limit has become the radiating surface of light fixture, divide top split and following partly body in the semicolumn again, the centre of upper part body is provided with the round hole of the sheathed lamp stand head of an energy size, be used for installing and fixing entire radiator, be provided with the many fin that are connected with lower body around the circle hole, formed heat dissipation channel between fin and the fin.The radiator of single light illumination lamp of above-mentioned a kind of super-high-power LED wherein vacuum cavity is the important composition part of radiator, its height accounts for the sub-fraction of entire radiator height, length, width and radiator are basic identical, following part by radiator is formed, two connects sealing by aluminium sheet and forms a vacuum cavity, loads onto one and vacuumizes and inject working solution.The lower body part, just the vacuum cavity baseplane is provided with the exhaust position that can be hinged with several led light source pedestals of combination, is provided with many shorter fin around the led light source pedestal, helps the led chip heat radiation.

The outward appearance of described radiator can be determined design by demand attractive in appearance, and the big I of radiator press the watt level of led light source, decides by the calculation area of dissipation, can apply in a flexible way in a word, but not violate the spiritual scope of this area patent of the present invention.After adopting technique scheme, determined the heat radiation difficult problem that the heat of single light illumination lamp of a kind of super-high-power LED is concentrated, made led chip keep low-temperature condition to play conclusive effect service life prolonging LED.
