Abstract

There is provided a system comprising a driver and a control module, the control module capable of translating a received control signal having a first control scheme into a driver control signal having a predetermined second control scheme; and wherein the driver is configured for generating a driver output based on the identity of the first control scheme and the driver control signal. A driver, control module, and a method of controlling an LED system are also provided.

Claims (35)

1. A system that receives a control signal having a first control scheme, comprising:

a driver and a control module,

wherein the control module translates the received first control scheme into a predetermined second control scheme, when the first control scheme is different from the predetermined second control scheme;

wherein the control module generates an identity voltage associated with the first control scheme;

wherein the control module outputs to the driver

a driver control signal comprising the predetermined second control scheme, and

the identity voltage; and

wherein the driver generates a driver output based on the identity voltage and the driver control signal.

2. The system of claim 1 , wherein the control module comprises a micro control unit for identifying the first control scheme and outputting the identify voltage associated with the first control scheme.

3. The system of claim 1 , wherein the first control scheme is different from the predetermined second control scheme.

4. The system of claim 1 , wherein, when the first control scheme of the received control signal is the same as predetermined second controls scheme, the control module directly transmits the first control scheme to the driver.

5. The system of claim 1 , further comprising at least one external control device from which the received control signal is transmitted to the control module, wherein at least one external control device is selected from the group consisting of a PC, tablet, phone, Bluetooth or Wi-Fi wall switch, IoT enabled device, and remote control.

6. The system of claim 1 , wherein the driver comprises firmware that generates the driver output based on the identity voltage and the driver control signal received from the control module.

7. The system of claim 6 , wherein the firmware comprises a lookup table.

8. The system of claim 1 , wherein the driver and control module are physically located on separate circuit boards.

9. The system of claim 1 , wherein the predetermined second control scheme is Pulse Width Modulated.

10. The system of claim 1 , wherein the predetermined second control scheme is selected from the group consisting of 0-10V, DALI, Wi-Fi, Zigbee, Thread, DMX 512, and Bluetooth.

11. The system of claim 1 , wherein the driver and the control module are electrically connected by wires comprising a CAT5 cable.

12. The system of claim 11 , wherein the driver and the control module are electrically connected by cables terminating with RJ45 connectors.

13. The system of claim 1 , wherein the control module comprises firmware for translating the received control signal having a first control scheme into a driver control signal having a predetermined second control scheme.

14. The system of claim 1 , wherein the control module comprises firmware for identifying the first control scheme.

15. A system that receives a control signal having a first control scheme, comprising:

a driver and a control module,

wherein the control module translates the received first control scheme into a predetermined second control scheme, wherein the predetermined second control scheme is a pulse width modulated driver control signal, when the first control scheme is different from the pulse width modulated driver control signal;

wherein the control module generates an identity voltage associated with the first control scheme;

wherein the control module outputs to the driver

the pulse width modulated driver control signal, and

the identity voltage; and

wherein the driver generates a driver output based on the identity voltage of the first control scheme and the pulse width modulated driver control signal.

16. A method of controlling an LED system that receives a control signal, the method comprising the steps of:

providing a control module and LED driver,

translating the control signal having a first control scheme into a predetermined second control scheme, wherein the predetermined second control scheme is a pulse width modulated driver control signal, when the first control scheme is different from the pulse width modulated driver control signal, and wherein the translating is performed by the control module;

generating, with the control module, an identity voltage associated with the first control scheme;

transmitting the pulse width modulated driver control signal and the identity voltage to the LED driver; and

generating an LED driver output based on the identity voltage and the pulse width modulated driver control signal.
