LED lighting system
First Claim
1. An LED lighting system, comprising:
- a support structure spanning between a first end and a second end, the support structure being heat conductive and rigid;
at least the first end of the support structure carrying electrical connectors for connection to a power source;
at least one LED array extending along the support structure; and
power control circuitry for the at least one LED array, the power control circuitry being carried by the support structure and being in electrical communication with the electrical connectors,wherein;
the power control circuitry is configured to provide current control for the LED array;
the at least one LED array is supported by a circuit board and the corresponding power control circuitry is provided on the circuit board;
the at least one LED array is divided into sets of LEDs; and
the power control circuitry is formed of multiple current controllers, each current controller of the multiple current controllers providing current control for a corresponding set of LEDs in the LED array.

Abstract
A light emitting diode lighting device and system that can be used for illuminating the interior and/or exterior of vehicles, aircraft, watercraft, signage or buildings is provided. It includes a voltage feedback constant current power supply circuitry and high power LEDs. The printed circuit assemblies are firmly mounted onto a continuous or semi-continuous mounting channel case that also works as a heat sink. By this means, it not only increases the reliability of the LED lighting tube but also it provides sufficient heat dissipation capability for the heat generated by the LEDs. Since the operating temperature of the LEDs is controlled and stays in cool condition, it dramatically increases the LED'"'"'s lifetime and efficiency. The end caps of this LED lighting device are fully compatible with existing conventional fluorescent light fixtures and can directly replace those fluorescent lighting tubes in vehicles, mass-transit, watercrafts, aircrafts, signage, furniture, equipment or buildings with minimal modifications.
