Description

Integral LED illumination phase transition of vacuum technology LED module
Technical field
The utility model relates to the LED module of lighting field.
Background technology
LED module forms a cell cube by radiator, LED light source, lens, black box, power supply etc., and LED illumination product adopts one or several module to make different products.
The module that current LED illumination adopts mainly contains two kinds of patterns, and one is the module adopting single 1W-3W LED light source, and because distribution of light sources area is comparatively large, basic employing aluminium section bar carrys out modularity as radiator and makes product, application relative maturity.But it is little to there is single module power, when making relatively high power lighting, the shortcomings such as light fixture is bulky, heavy.
Two is the modules adopting great power LED COB light source to make, and because the manufacture of great power LED COB light source is towards high-performance, integrated and miniaturization, the power density of its chip can reach hundreds of W/cm2.The electro-optical efficiency of great power LED is about 30%, and the electric energy of about 70% is converted to heat and distributes, and therefore the heat flow density at its chip place is high.
And the junction temperature rising of LED can cause luminous efficiency decline, the lost of life, luminescent spectrum to produce drift, serious also can burn chip, so heat radiation needs one of key problems-solving in great power LED illumination.
Now commercially the scheme of the radiator of most high-power LED illumination product is all adopt die casting aluminium or section bar aluminium to make, due to heat conductivility and the radiating efficiency problem of material, substantially all bulky, cost performance is low, and still cannot to deal with problems well.Super high power radiator (200W-500W) does not also have feasible product at present.
Summary of the invention
The utility model provides a kind of heat conduction, the rapid heat dissipation that realize great power LED COB light source, and volume is little, the LED illumination phase transition of vacuum technology LED module that cost is low.
The utility model is achieved by the following technical solution: a kind of integral LED illumination phase transition of vacuum technology LED module, comprise that LED light source is provided with radiator, radiator connects fin, its technical characteristics is that radiator establishes the base plate of vacuum cavity in being, vacuum chamber is filled with ultralow temperature medium; Be provided with narrow tube passage in vacuum chamber, narrow tube passage is the hollow tube around vacuum chamber surrounding; Vacuum chamber four perisporium is provided with microflute group structure, the slot line structure be namely linked to be by wavy slotted eye;
The boiling point of described ultralow temperature medium is 13 DEG C, and vacuum strength is greater than 10 -2holder.
This module adopts phase transition of vacuum technology, realizes the quick conductive of module, heat radiation thus realize the high life of light source module, the advantage of low cost.This module is not changing under the too many condition of module size, and the mounting means of the compatible all LED light sources of energy, is particularly suitable for great power LED COB light source to make LED illumination product.
This technology utilizes traditional aluminium section bar change structure, forms vacuum cavity, add ultralow temperature medium in cavity by solder technology, and boiling point 13 DEG C, is better than existing heat-conducting medium greatly.And heat conduction inner chamber is corrosion-free, substantially increase the heat transfer rate of phase transformation medium, achieve moment heat conduction and heat radiation, reduce temperature rise.Temperature rise 30 ° of about C are reduced than traditional heat sinks.
Simultaneously chamber wall increases microflute group structure in vacuo, increase the heat transfer of vacuum chamber, heating surface area, will have superiority many than other porous materials of traditional increase.Under ensureing inner vacuum state, ultralow temperature medium can better work, and at whole vacuum chamber in seal process, adds narrow tube passage, such energy ensures that inner ultralow temperature medium is at whole cavity internal circulation flow, thus makes whole radiator become a samming body.

Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of narrow tube passage in vacuum chamber;
Fig. 3 is the A-A sectional view of Fig. 2.
Detailed description of the invention:
As shown in Figure 1, Figure 2, Figure 3 shows, this LED illumination phase transition of vacuum technology LED module, comprises that LED light source 8 is provided with radiator 1, radiator connects fin 2, and the base plate 4 of vacuum cavity 3 established by radiator in being, vacuum chamber is filled with ultralow temperature medium 5; Be provided with narrow tube passage 6 in vacuum chamber, narrow tube passage is the hollow tube around vacuum chamber surrounding; Vacuum chamber four perisporium is provided with microflute group structure 7, the slot line structure be namely linked to be by wavy slotted eye 7-1;
The boiling point of described ultralow temperature medium is 13 DEG C, and vacuum strength is greater than 10 -2holder.
This module adopts phase transition of vacuum technology, realizes the quick conductive of module, heat radiation thus realize the high life of light source module, the advantage of low cost.This module is not changing under the too many condition of module size, and the mounting means of the compatible all LED light sources of energy, is particularly suitable for great power LED COB light source to make LED illumination product.
This technology utilizes traditional aluminium section bar change structure, forms vacuum cavity, add ultralow temperature medium in cavity by solder technology, and boiling point 13 DEG C, is better than existing heat-conducting medium greatly.And heat conduction inner chamber is corrosion-free, substantially increase the heat transfer rate of phase transformation medium, achieve moment heat conduction and heat radiation, reduce temperature rise.Temperature rise 30 ° of about C are reduced than traditional heat sinks.
