LED lighting system
First Claim
1. An LED lighting system, comprising:
- a housing forming a channel and being heat conductive and rigid;
at least a first end of the housing having electrical connectors for connection to a power source;
an LED array extending along the housing within the channel, each LED in the LED array having a power rating of greater than 0.5 watts; and
onboard current control circuitry for the LED array, the onboard current control circuitry being carried by the housing and being in electrical communication with the electrical connectors.

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 or buildings with minimal modifications.
