With the different capabilities of the manufacturers, the LED industry is divided into high-tech standards, high gross profit, and general technical standards, low gross profit, and two modes. The controversial LED cooling technology , although many manufacturers of low-end LED products do not care, but the development of related technologies is changing with each passing day, in order to create high-margin, high value-added applications, but related The cost and difficulty of development are also one of the reasons why many manufacturers are deterred from choosing other products.
And what we are going to introduce this time is the new LED cooling technology IVC, which is the vacuum equalization plate structure. Its principle is very simple, that is, by extracting air, an internal hollow metal object is established, and then a hollow portion of the metal material is filled with a special medium and a saturated vapor substance of a homogenous material.
Such a structure is very similar to a water-cooled, liquid-cooled circulating pipeline system. As long as the high-power LED emits light, the heat generated by the LED will cause the liquid state material in the vacuum-averaged metal next to the LED to become vaporized. The heat-bearing gas will diffuse to the gas chamber on the other side of the vacuum equalization plate, and the heat will be released through this other heat-dissipating material in this area, and the cooled gas will be liquefied into a liquid due to temperature. The state material flows back into the vacuum tempering plate next to the original heating LED.
As long as the process of vaporization and liquefaction continues to circulate, the heat generated by the LED light source can be automatically taken out, thereby reducing the problem of brightness attenuation (light decay) of the LED light source, prolonging the life of the LED, and the manufacturer can further fully utilize the high power. The LED has a stronger luminous efficiency and achieves a higher brightness per lumen.
Since the vacuum tempering plate does not need to be powered by other heat-dissipating methods, it can be said to be a set of cooling system that operates in a completely passive state, which is very helpful for the development of LED heat-dissipation technology .
