In this paper, a temperature control for LED (light emitting diode) lamp using a cooling fan is studied. An efficient temperature control scheme for the LED lamp using the fan wind at the lowest sound noise is studied. For the study, after measurement of the minimum sound noise of the fan and related temperature of the LED lamp through tests, experiments on temperature control of the LED lamp using the fan with various size of heat sinks was performed. To reduce the fan sound noise, a method of reducing the operation time with optimal size of the heat sink was studied. Also, a control of LED lamps using RF communication was studied.
