Mingfa Tech is a LED thermal solution leading provider who is certified as LED thermal solution partner of Bridgelux, Xicato, LG, Seoul, Lumileds etc...
Mingfa Tech has been focusing on LED thermal solution for over 6 years in LED industry. All Mingfa Tech’s designed LED coolers are compatible with branded LED modules / LED arrays / LED chip on boards and its clients are specialized in high-end solid state lighting for many years.
In order to let the clients have a good understanding of EtraLED-7038, the unique advantages for them are listed as below.
1. With diameters 2mm~4mm smaller than competitors' star heat sink (led cooler).
2. With around 10% more cooling surfaces than competitors' star heat sink (led cooler).
3. At least 2 or 4 fins for side mounting options, more flexible assembly than competitors' star heat sink (led cooler).
4. More optional self-tapping holes compatible with over 20 branded LEDs, such as Xicato, Bridgelux, Citizen, GE Infusion, Lumileds, Tridonic, Cree, Philips, Osram, ADURA, Lustrous, Sharp , Lumens, Edison Opto, Prolight Opto, Luminus, Nichia, Seoul Semiconductor, LG Innotek, Vossloh Schwabe, Samsung, Megaman, and so on.
Most properties of an LED depend on the temperature. Not only the luminous flux and therefore the efficiency but also the lifetime, wavelength and the chromaticity coordinates change with temperature. The higher the temperature, the more the properties are influenced negatively. In general, there are three physical mechanisms to transport heat: radiation, conduction and convection. The design of a heat sink (led cooler) has to consider these mechanisms to improve the thermal performance.
In comparison to traditional incandescent lamps the thermal power loss of the LED itself is not radiated and has to be dissipated by thermal conduction from the LED into the applied heat sink (led cooler). The design of the heat sink (led cooler) has to ensure that the heat is conducted through the material to the surfaces where it is transported to the environment by convection and radiation. Considering a given space available for a heat sink ( led cooler) and thus the same surface area of circumference, the special design of the heat sink ( led cooler) has a minor impact on the heat dissipation by radiation whereas the heat conduction and convection are effected by the material and the geometry of the heat sink ( led cooler). Thus, the design of a heat sink (led cooler) has to fulfil two aims: good thermal conduction in the heat sink (led cooler) and good thermal convection on its surfaces.
