"Cooling Fan Manufacturer" of life has been extended, and even some manufacturers claimed the life of LED fan LED life much longer than that, but anyway, by mechanical contact with the cooling fan is not always reassuring to use in high reliability requirements of high-power LED lamps, adding an electric fan running condition monitoring circuit, in "Cooling Fan Manufacturer" appear automatically cut off when the main circuit fault stall, overheat protection LED Buzhi Yu damage assessment for this idea . Based on this idea has developed a fan detection circuit. LED life is inversely proportional to the temperature of the PN junction, and in the limited space in the high-power LED lamps, can not rely on the use of a greater volume of heat sinks to achieve the LED temperature control. Like on LED track lights, DC "Cooling Fan Manufacturer" forced cooling becomes a last resort option.
