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.
