Abstract

A group of LED fixtures wherein power is delivered to each fixture in the group from central power unit thus eliminating the necessity of providing a separate power sauce to each fixture.

Claims

1. A LED fixture system comprising:

a plurality of LEDs, said LEDs connected in series as a plurality of arrays, said arrays being connected in parallel;

a printed circuit board, said plurality of LEDs being mounted to said printed circuit board, said printed circuit board being coupled to a bypass circuit wherein is one or more LEDs fail causing an open circuit, the remainder of the circuit will remain energized;

a plurality of LED fixtures, said printed circuit board being coupled to said fixtures;

a central power unit having an input and an output, said central power unit being coupled to said plurality of LED fixtures; and

a power source coupled to said central power unit, application of power to said central power unit causing said LEDs to generate light.

2. The system of claim 1 wherein the output of said central power unit is between 300 and 500 VDC.

3. The system of claim 2 wherein said central power unit provides a constant controlled current and delivers approximately between 3 and 200 amps.
