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.

Claims

1. 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.

2. The device as claimed in the claim 1, wherein the input signal, which is an electric control signal, comprises a low-frequency electric power signal and a high-frequency control signal.

3. The device as claimed in the claim 1, wherein the low pass filter is connected with a rectifier for rectifying the low-frequency signal.

4. The device as claimed in the claim 3, wherein the rectifier is connected with the track lamps to provide the track lamps electricity.

5. The device as claimed in the claim 4, wherein the track lamps are light emitting diodes (LEDs).

6. A track lamp control module comprising:

a control device for providing a man-machine interface;

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 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.

7. The track lamp control module as claimed in the claim 6, wherein the input signal, which is an electric control signal, comprises a low-frequency electric power signal and a high-frequency control signal.

8. The track lamp control module as claimed in the claim 6, wherein the low pass filter is connected with a rectifier for rectifying the low-frequency signal.
