Abstract

A master lighting fixture and a satellite lighting fixture can each include an LED board including multiple LEDs that can emit visible light. A power supply and a LED regulator can be connected to the LED board in the master lighting fixture to provide power to operate the LED board. The LED board in the master lighting fixture can be connected to the LED board in the satellite lighting fixture to form a circuit to allow the power provided by the LED driver to be transmitted to the LED board in the satellite lighting fixture. A defect in the LED board in the master lighting fixture or the satellite lighting fixture can open the circuit, which can prevent power from being transmitted through the LED boards to enhance the performance of LEDs in the LED boards or reduce a risk of damage that can be caused by the LED boards.

First claim

What is claimed is:

1. A modular master lighting fixture, comprising:
an input for receiving a voltage;
a first light-emitting diode (“LED”) driver having a first output and a second output, the first LED driver configured to receive the voltage;
a first plurality of LEDs on a first LED board, wherein the first LED board has a first power connection point and a second power connection point; and
a second plurality of LEDs on a second LED board, wherein the second LED board has a first power connection point and a second power connection point,
wherein the first output of the first LED driver is connected to the first power connection point of the first LED board to power the first LED board and the second output of the first LED driver is connected to the second power connection point of the second LED board to power the second LED board, and
wherein the second power connection point of the first LED board is couplable to a first connection point on an external circuit and the first power connection point of the second LED board is couplable to a second connection point on the external circuit to power the external circuit when the second power connection point of the first LED board is coupled to the first connection point and the first power connection point of the second LED board is coupled to the second connection point; and
the external circuit, wherein the external circuit has a first power connection point and a second power connection point,
wherein a connection between the second power connection point of the first LED board of the modular master lighting fixture and the first power connection point of the external circuit bypasses the second LED board, and a connection between the first power connection point of the second LED board of the modular master lighting fixture and the second power connection point of the external circuit bypasses the first LED board.

2. The modular master lighting fixture of claim 1 , wherein the external circuit is a satellite lighting fixture, the first power connection point of the external circuit corresponds to a first power connection point of the satellite lighting fixture and the second power connection point of the external circuit corresponds to a second power connection point of the satellite lighting fixture, comprising:
a third plurality of LEDs on a first LED board in the satellite lighting fixture, wherein the first LED board in the satellite lighting fixture has a first power connection point and a second power connection point; and
a fourth plurality of LEDs on a second LED board in the satellite lighting fixture, wherein the second LED board in the satellite lighting fixture has a first power connection point and a second power connection point,
wherein the first power connection point of the satellite lighting fixture is connected to the first power connection point of the first LED board in the satellite lighting fixture and the second power connection point of the satellite lighting fixture is connected to the second power connection point of the second LED board in the satellite lighting fixture to power the satellite lighting fixture.

3. The modular master lighting fixture of claim 2 , wherein the second power connection point of the first LED board in the satellite lighting fixture connects to the first power connection point of the second LED board in the satellite lighting fixture to form a circuit between the modular master lighting fixture and the external circuit to allow the first LED driver to power the first LED board in the modular master lighting fixture, the second LED board in the modular master lighting fixture, the first LED board in the satellite lighting fixture, and the second LED board in the satellite lighting fixture.

4. The modular master lighting fixture of claim 3 , wherein a failure of the first LED board in the modular master lighting fixture, the second LED board in the modular master lighting fixture, the first LED board in the satellite lighting fixture, or the second LED board in the satellite lighting fixture causes an open circuit condition between the modular master lighting fixture and the external circuit, the open circuit condition preventing the first LED board in the modular master lighting fixture, the second LED board in the modular master lighting fixture, the first LED board in the satellite lighting fixture, and the second LED board in the satellite lighting fixture from receiving power from the first LED driver.

5. The modular master lighting fixture of claim 4 , wherein the failure includes an electrical failure in the first LED board in the modular master lighting fixture, the second LED board in the modular master lighting fixture, the first LED board in the satellite lighting fixture, or the second LED board in the satellite lighting fixture.

6. The modular master lighting fixture of claim 3 , wherein the power provided to each of the first and second LED boards in the modular master lighting fixture and the first and second LED boards in the satellite lighting fixture is approximately the same.

7. The modular master lighting fixture of claim 6 , wherein an open circuit is formed between the modular master lighting fixture and the external circuit in response to the first LED board in the modular master lighting fixture, the second LED board in the modular master lighting fixture, the first LED board in the satellite lighting fixture, or the second LED board in the satellite lighting fixture receiving a voltage above or below a power threshold, the open circuit preventing the first LED board in the modular master lighting fixture, the second LED board in the modular master lighting fixture, the first LED board in the satellite lighting fixture, and the second LED board in the satellite lighting fixture from receiving power from the first LED driver.

8. The modular master lighting fixture of claim 1 , wherein the modular master lighting fixture further comprises a second LED driver, the second LED driver having a third output and a fourth output, the second LED driver configured to receive the voltage, comprising:
a third plurality of LEDs on a first LED board in a satellite lighting fixture, wherein the first LED board in the satellite lighting fixture has a first power connection point and a second power connection point; and
a fourth plurality of LEDs on a second LED board in the satellite lighting fixture, wherein the second LED board in the satellite lighting fixture has a first power connection point and a second power connection point,
wherein the third output of the second LED driver is connected to the first power connection point of the first LED board of the satellite lighting fixture and the fourth output of the second LED driver is connected to the second power connection point of the second LED board in the satellite lighting fixture, and
wherein the second power connection point of the first LED board of the satellite lighting fixture connects to the first power connection point of the second LED board of the satellite lighting fixture to form a circuit between the modular master lighting fixture and the satellite lighting fixture to allow the first LED driver to provide power to the first LED board in the modular master lighting fixture and the second LED board in the modular master lighting fixture and to allow the second LED driver to provide power to the first LED board in the satellite lighting fixture and the second LED board in the satellite lighting fixture.
