Mingfa Tech is an LED thermal solution leading provider who was certified as LED cooling partner of top LED brands like Bridgelux, Xicato, LG, Seoul, Lumileds etc.
Mingfa Tech has established many distribution relationships around the world, more than 20 countries, such as UK, Germany, Italy, Netherlands, Belgium, Spain, Portugual, USA, Canada, etc., All of our distributors are quite famous, including Melchioni, Batenburg, Sutelco, AduraLED, and so on.
Mingfa Tech has designed and manufactured its own LED cooling products for top LED lighting manufacturers. Mingfa Tech owns the patent for EtraLED heat sink series, which are with self tapping holes for options. All kinds of brand COB leds can be directly mounted with by EtraLED coolers. This perfect solution did also help the client save much time and make it convenient.
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 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. The design of the heat sink 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 and thus the same surface area of circumference, the special design of the heat sink 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. Thus, the design of a heat sink has to fulfill two aims: good thermal conduction in the heat sink and good thermal convection on its surfaces.
Mingfa Tech’s LED thermal solution can solve the said above problem successfully, especially choosen Mingfa Tech’s EtraLED Heat sink series by clients. Mingfa Tech is always there to provide full technical support when clients need any help for their LED thermal management, with the detailed technical data sheets including but not limited to the following values:
1). The air temperature under which the LED will be lightened up
2). The total of all thermal resistances between the ambient air and the LED junction
3). Total heat that will dissipated in Watts
After having compiled the above mentioned data, the heat sink e-calculators can be used to find out the exact measure of thermal conductivity value of LED heat sink that will be ideal for the clients’ LED lighting system.
