ABSTRACT:
A device for controlling track lamps used to control the light-emitting order or brightness of the track lamps. The device includes: a low pass filter for obtaining a low-frequent signal from an input signal; a high pass filter for obtaining a high-frequent signal from the input signal; a microprocessor connected with the high pass filter to process the high-frequent signal; an Internet Protocol (IP) setting circuit connected with the microprocessor for providing a user to set the IP addresses of the track lamps; and pulse modulation processors for receiving the processed high-frequent signal sent from the microprocessor and modulating the pulse width of the processed high-frequent signal. Thereby, the light-emitting order, brightness or light-projecting angle can be controlled to enhance a presented light effect.
