The LED lamps and lanterns are the illumination diode for the photo source lamps and lanterns, it will have the huge quantity of heat in the shining process, conducted and radiates the LED lamps and lanterns' important question. Then, should the LED radiator in the selection process, what material quality select?
In fact, in the LED domain, did not recommend generally the iron takes the radiator, because the hard thermal conductivity is low, namely is bad for the capacity of heat transmission. But as a result of the market competition pressure high, is the compression cost, some factories will select the iron to take the radiator, certainly this will be a gain does not equal the loss.
The aluminum is the good radiation material which in the LED lamps and lanterns manufacture recognizes. On the one hand is its good coefficient of heat radiation, on the other hand is its price.
In high efficiency LED lamps and lanterns, if achieves the 250W above lamps and lanterns, will then add or all with the copper radiator, this will be because the copper will radiate is quicker.
The low power lamps and lanterns, compared with popular model alclad radiation processing, namely use heat conduction plastic and aluminum radiation union, on the one hand has achieved the radiation need, on the other hand has saved the cost, because the plastic must be cheaper than the aluminum.
Regarding the high efficiency LED lamps and lanterns, one method is inducts the heat conduction liquid in the aluminum radiator, through this liquid physical chemistry change, but achieves the good radiation.
