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.

Abstract: A method of electrical insulation used in the high voltage (>60V) LED lighting system. The LED lighting system comprises the housing, end cap, lens and PCBs. The LEDs are mounted on the PCBs. The insulating housing or channel between the PCBs and the housing prevents the electrical shock and increase the clearance and creepage distance. The insulating housing or channel is made of materials with good heat conductivity and high insulation.
