LED lamps, heat is directly related to the quality and life of the product. But because they were some businesses speculation, and the so-called experts misleading, there has been some misunderstanding. See if you do not be misled?
1. Superstition thermal conductivity material
Because the use of high-tech materials can dissipate the heat. In fact, ordinary aluminum heat after several tests, the temperature of the heat sink than just the bottom of the radiator is 3-5 degrees Celsius higher. That is, if true particularly preferably used up to a thermally conductive material,
LED Candle Bulb in the case of thermal resistance is zero, it can temperature was lowered to 3-5 degrees Celsius.
Superstition heat pipe
The heat pipe has a very good thermal conductivity, it is beyond doubt. From the export of thermal heat sink eventually need air convection tropical go. If there is no cooling fins, heat pipes soon reach thermal equilibrium temperature rise together with the heat sink. The increase in heat pipe cooling fins,
LED Spotlight eventually fin heat. And the point of contact of the fins and heat pipe, but not as good as the other way to reach. The result is the high cost, the cooling effect is not improved. However use led integrated heat pipe thermal conductivity or useful, but the structure is reasonable!
Superstition nm radiation material
The proportion of the radiation heat lighting temperature of around 50 degrees Celsius case can be ignored. Radiation coating manufacturers propaganda even as they promote as the good radiation effects,
LED Floodlight and even the ability to radiate blackbody radiation, but a few percent of the proportion of its heat. How meaning can also be considered and the coating itself will hinder the export of the heat, thus affecting the convection cooling.
