Abstract

A method of controlling an LED system with a control signal having a first control scheme may include providing a lighting module including a control module, an LED driver connected to the control module, and at least one LED connected to the LED driver; receiving, at the control module, the control signal having a first control scheme; comparing the first control scheme to a predetermined second control scheme; when the comparing determines that the first control scheme is the same as the predetermined second control scheme, transmitting to the LED driver a driver control signal including the predetermined second control scheme; and when the comparing determines that the first control scheme is different from the predetermined second control scheme, translating, with the control module, the first control scheme into the predetermined second control scheme and then transmitting to the LED driver a driver control signal including the predetermined second control scheme.

First claim

What is claimed is:

1. A method of controlling an LED system with a workpiece control signal having a first control scheme, the method comprising:
providing a lighting module comprising a control module, an LED driver connected to said control module, and at least one LED connected to said LED driver;
receiving, at said control module, the workpiece control signal having a first control scheme;
comparing the first control scheme to a predetermined second control scheme;
when said comparing determines that the first control scheme is the same as said predetermined second control scheme, transmitting to said LED driver a driver control signal comprising said predetermined second control scheme; and
when said comparing determines that the first control scheme is different from said predetermined second control scheme, translating, with said control module, the first control scheme into said predetermined second control scheme and then transmitting to said LED driver a driver control signal comprising said predetermined second control scheme.

2. The method of claim 1 , further comprising receiving said driver control signal at said LED driver after said transmitting, and
in response to said receiving, generating an LED driver output.

3. The method of claim 2 , wherein said LED driver operates in a current control mode, and wherein said generating comprises producing a constant-current output.

4. The method of claim 2 , further comprising receiving said LED driver output at said one or more LEDs, and dimming at least one said LED in response to said receiving.

5. The method of claim 2 , further comprising receiving said LED driver output at said one or more LEDs, and changing the CCT of light output by said lighting module in response to said receiving.

6. The method of claim 1 , wherein said LED driver comprises at least one channel, and further comprising performing, for each channel:
said receiving and said comparing; and
when said comparing determines that the first control scheme is the same as said predetermined second control scheme, transmitting to said LED driver a driver control signal comprising said predetermined second control scheme;
when said comparing determines that the first control scheme is different from said predetermined second control scheme, translating, with said control module, the first control scheme into said predetermined second control scheme and then transmitting to said LED driver a driver control signal comprising said predetermined second control scheme.

7. The method of claim 6 , wherein said driver controls a plurality of first LEDs through a first channel and a plurality of LEDs through a second channel.

8. The method of claim 7 , wherein said driver controls at least one property of light emitted by the lighting module by differentially controlling first LEDs and second LEDs.

9. The method of claim 7 , wherein said at least one property of light emitted by the lighting module is brightness.

10. The method of claim 7 , wherein said at least one property of light emitted by the lighting module is CCT.

11. The method of claim 1 , wherein said driver control signal is an analog signal.

12. A method of controlling an LED system with a workpiece control signal having a first control scheme, the method comprising the steps of:
providing a lighting module comprising a control module, an LED driver connected to the control module, said LED driver comprising at least one channel, and at least one LED connected to said LED driver;
receiving, at said control module, the workpiece control signal having a first control scheme;
converting, at said control module, the first control scheme into a predetermined second control scheme, when the first control scheme is different from said predetermined second control scheme;
generating, at said control module, an identity voltage associated with the first control scheme;
transmitting to said LED driver said identity voltage and a driver control signal comprising said predetermined second control scheme.

13. The method of claim 12 , further comprising generating an LED driver output based on said identity voltage and said driver control signal.

14. The method of claim 12 , wherein said driver control signal is a digital signal.

15. The method of claim 12 , wherein said driver control signal is an analog signal having a voltage X, wherein 0 V≤X≤10 V.

16. The method of claim 12 , wherein said identity voltage is generated within one of a plurality of different voltage ranges, and wherein each said voltage range is associated with a different said first control scheme.

17. A lighting module that receives a control signal having a first control scheme, comprising:
a driver;
a control module connected to said driver, said control module comprising
a transceiver,
an antenna connected to said transceiver, said antenna configured to receive the control signal, and
controller logic connected to said transceiver;

wherein said controller logic translates the received first control scheme into a predetermined second control scheme, when the first control scheme is different from said predetermined second control scheme;
wherein said controller logic generates an identity voltage correlated with the received first control scheme; and
wherein said controller logic outputs to said driver
a driver control signal comprising said predetermined second control scheme, and
said identity voltage.

18. The lighting module of claim 17 , wherein said driver is a multi-channel driver.

19. The lighting module of claim 17 , wherein said controller logic comprises a micro control unit.

20. The lighting module of claim 17 , wherein said control module is connected to said driver by a wired connection.
