Abstract
The present invention is an alternative lighting technology to form light emitting diode (LED) light tube. The tubular or circular LED tube is formed by transparent plastic and a metal heat sink that includes LEDs soldered onto a metal core printed circuit board with a special arrangement to achieve greater brightness than an equal distance arrangement. All LEDs are directly inserted into the metal core printed circuit board with a unique insulation coating to allow the LED anode and cathode to be inserted into the metal core printed circuit board and soldered on the opposite side of the metal core printed circuit board. It can connect one or more control units to control intensity.
