A device for controlling operation of lamps is provided. The device includes a power outputting part to provide a power voltage to a lamp array having at least one lamp; a temperature sensing part to detect a temperature of the lamp and to generate a temperature signal; and a controlling part to compare the temperature of the lamp with a threshold temperature to generate a first switching signal, in response to the temperature signal, and to output the first switching signal to the power outputting part to feedback control the temperature of the lamp.
