Abstract

A lighting system includes a remotely controllable step dimmer for controlling one or more fluorescent light fixtures with a fixed or transportable light controller with a wireless signal transmitter and at least a first control input or switch configured for manual actuation by a lighting system user. The light controller transmitter is configured to wirelessly transmit one of a plurality of uniquely encoded or modulated lighting control signals to at least a first light fixture'"'"'s wireless receiver.

Claims

1. A lighting system including a remotely controllable step dimmer for controlling one or more fluorescent light fixtures, comprising:

at least one light fixture including a wireless receiver configured to receive and demodulate lighting control signals transmitted from a remotely located light controller;

a light controller having a wireless signal transmitter and at least a first control input or switch configured for manual actuation by a lighting system user;

said light controller transmitter being configured to wirelessly transmit a selectable one of a plurality of uniquely encoded or modulated lighting control signals to said at least one light fixture wireless receiver; and

circuitry in said wireless receiver for generating a light fixture ballast control signal in response to demodulated lighting control signals.

2. The lighting system of claim 1, wherein said at least one light fixture also includes a first multi-level fluorescent lamp ballast configured to sense and respond to said light fixture ballast control signal and having first and second ballast outputs;

said at least one light fixture having a lamp socket adapted to receive at least one fluorescent lamp having first and second contacts, whereby said first contact is connected to said first ballast output and said second contact is connected to said second ballast output; and

wherein said light controller senses a user'"'"'s actuation of said control input and, in response, transmits light control signal selected from said plurality of uniquely encoded or modulated lighting control signals, and said receiver controls said first lamp in response thereto.

3. The lighting system of claim 2, wherein said control input for said light controller comprises multiple manually operable switches connected to said transmitter for selecting one of said plurality of uniquely encoded or modulated lighting control signals.

4. The lighting system of claim 3, wherein said transmitter is a radio frequency transmitter and said receiver is a wireless frequency receiver.

5. The lighting system of claim 4, wherein said circuitry in said wireless receiver for generating a light fixture ballast control signal in response to demodulated lighting control signals comprises relays connected to said receiver to produce selected first and second ballast outputs.

6. The lighting system of claim 5, wherein said fluorescent lamp is a fluorescent linear bulb or tube having first and second contacts.

7. A method for remotely controlling luminous intensity generated by one or more fluorescent light fixtures, comprising:

incorporating in at least one light fixture a wireless receiver configured to receive and demodulate lighting control signals transmitted from a remotely located light controller;

providing, in a light controller, a wireless signal transmitter and at least a first control input configured for manual actuation by a lighting system user;

incorporating in said transmitter circuitry for generating a plurality of uniquely encoded lighting control signals, and configuring said light controller transmitter to wirelessly transmit a selected one of said plurality of uniquely encoded lighting control signals to said wireless receiver in said at least one light fixture; and

receiving and demodulating in said wireless receiver said selected wirelessly transmitted lighting control signal.

8. The method for remotely controlling luminous intensity generated by one or more fluorescent light fixtures of claim 7, further comprising:

generating in said receiver a light fixture ballast control signal in response to said demodulated lighting control signals;

providing in said first light fixture a first multi-level fluorescent lamp ballast configured to sense and respond to said light fixture ballast control signal and having first and second ballast outputs;

providing in said first light fixture a lamp socket adapted to receive at least one fluorescent lamp having first and second contacts, whereby said first contact is connected to said first ballast output and said second contact is connected to said second ballast output;

sensing a user'"'"'s actuation of said light controller'"'"'s control input and, in response, transmitting a light control signal selected from said plurality of uniquely encoded lighting control signals, and

wherein said first fixture receiver controls a florescent lamp connected in said lamp socket in response to actuation of said lighting system controller by a user.

9. A remotely controllable light fixture including a step dimmer for controlling one or more step dimmable lamps, comprising:

a light fixture housing a wireless receiver configured to receive and demodulate lighting control signals transmitted from a remotely located light controller;

said light controller having a wireless signal transmitter and at least a first control input or switch configured for manual actuation by a lighting system user;

said light controller transmitter being configured to wirelessly transmit a selectable one of a plurality of uniquely encoded or modulated lighting control signals to said light fixture wireless receiver; and

circuitry in said wireless receiver for generating a light fixture control signal in response to demodulated lighting control signals.

10. The lighting system of claim 9, wherein said light fixture also includes a first multi-level fluorescent lamp ballast configured to sense and respond to said light fixture control signal by changing a first or second ballast outputs;

said at light fixture having a lamp socket adapted to receive at least one fluorescent lamp having first and second contacts, whereby said first contact is connected to said first ballast output and said second contact is connected to said second ballast output; and

wherein said light controller senses a user'"'"'s actuation of said control input and, in response, transmits light control signal selected from said plurality of uniquely encoded or modulated lighting control signals, and said receiver controls said first lamp in response thereto.

11. The lighting system of claim 10, wherein said control input for said light controller comprises multiple manually operable switches connected to said transmitter for selecting one of said plurality of uniquely encoded or modulated lighting control signals.

12. The lighting system of claim 11, wherein said transmitter is a radio frequency transmitter and said receiver is a wireless frequency receiver.

13. The lighting system of claim 12, wherein said circuitry in said wireless receiver for generating a light fixture ballast control signal in response to demodulated lighting control signals comprises relays connected to said receiver to produce selected first and second ballast outputs.

14. The lighting system of claim 13, wherein said fluorescent lamp is a fluorescent linear bulb or tube having first and second contacts.
