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.

Now, you can see the technical data of LED Cooler EtraLED- 7038 in below: 

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.

All Mingfa Tech’s clients enjoy 0-risk Guarantee during cooperation:

Mingfa Tech implements 100% refund policy on samples if unsatisfied by clients.
Mingfa Tech implements 100% free-recall policy for those defective parts if from bulk orders.
