Patent ID: 6895288

Claim:
A device for controlling track lamps comprising: a low pass filter for obtaining a low-frequency signal from an input signal; a high pass filter for obtaining a high-frequency signal from the input signal; a microprocessor connected with the high pass filter to process the high-frequency signal; an Internet Protocol (IP) setting circuit connected with the microprocessor for providing a user interface to set IP addresses of the track lamps, the IP setting circuit accepting an input of the IP addresses and an order of the track lamps from an external device selected from the group consisting of a computer, a cellular phone, a personal digital assistant (PDA) and a control panel; and a plurality of pulse modulation processors for receiving the processed high-frequency signal sent from the microprocessor and modulating a pulse width of the processed high-frequency signal; whereby the light-emitting order, the brightness and a light-projecting angle are controlled to enhance a presented light effect.
