1, I am from begin one's study LED encapsulation and LED uses, done first Technology Park solar LED street lamp in China, using the LED process of calendar year 2001, successively solved led chip, LED angle, change from small to big, LED constant power controller, LED angle lens, LED colour temperature, 2:LED light decay be serious, lifetime is short, have a strong impact on LED use value.The 3:LED heat abstractor directly influences LED life-span and light decay.4:LED is integrated in light decay in the same lamp holder, and is serious as the light, and 5: my witness illumination utilizes the LED first generation ten generation product quality processes " this ten generation product is all in my design office's display " till now.Therefore: a, invention LED heat radiation module have " forming module separately for 3568 10 ", b, LED medium circulation heat conduction method, c, the cold and hot liquid gas circulation of LED medium method, D, LED air-flow cooling method.

Three: summary of the invention: 1, goal of the invention: solved the LED heat dissipation problem; Solved LED light decay problem; Solved the LED life problems; Solved the integrated integrity problem of LED modularity; Solved that LED is high-power to be made up of modularization.Ever-changing of many uses.

2, the composition of technical solution of the present invention, structure and relation each other, (1), fin, (2), chip, (3), colloid, (4), plastics pvc, (5), plastic lens, (6), negative plate, (7), cooling tube, (8), cooling medium, (9), circulation pipe, (10), heat-conducting copper pipe, (11) fin, (12), led light source, (13), reflector, (14) and coupling head 1, (15) and coupling head 2

A, the thermoelectric separate package of LED at first; → module copper pipe casting (A---A) section; → polishing → typing → LED heating place and heat conduction place of module copper pipe are joined and the source of welding current (12), → the LED secondary light-distribution lens install (5), → the IP65 water-proofing treatment, → module copper pipe two layer medium inject (7), (9), (10), → medium injects three times of quantity Dayu heats, media expansion space, module heat-conducting circulating system Dayu (9), → injected media cooling layer (8).→ sealing, → the polishing moulding, → test entirely, → the finished product packing, → warehouse-in.

The composition of b, invention technical scheme, structure and each other relation are: (8) two layers of (heat-conducting layer and cooling layer) heat-conducting layer inside pipe walls circulation of dress R22 medium (9), (10) in the copper pipe material thermal conductivity is strong,, the cooling layer inwall purpose that main cooling medium gaseous state links to each other with outer wall fin (11) and allow the Nature air-flow dispel the heat for liquid (7) of not conducting heat that do not circulate.Solved the LED heat dissipation problem; Solved LED light decay problem; Solved the LED life problems; Solved the integrated integrity problem of LED modularity; Solved that LED is high-power to be made up of modularization.Ever-changing of many uses.

Useful effect: 1, a, LED characteristic are spot light (12), b, LED specific currents voltage, and c, LED characteristic beard and hair thermal conductance go out, and the illumination of d, LED characteristic need the orientation.2, follow characteristic: invented " LED medium strong heat-conducting circulating system module " and solved the characteristic deficiency effectively, reached the scientific module of LED, LED practicality module according to LED, LED stability module, LED longevity module, LED associativity module, the best module of LED heat conduction.
