Abstract: An LED lighting apparatus including an LED chip having at least one LED, a light reflector configured to direct light emitted by the LED at a predetermined direction and dispersion angle, a heat sink including a mounting base and cooling fins extending from a first side of the mounting base and with the LED chip secured to an opposite second side of the mounting base, a cooling fan attached to the heat sink adjacent distal ends of the plurality of fins, an electrical regulator electrically connected to the cooling fan to provide regulated power to the cooling fan, an LED driver electrically connected to the LED chip, and a thermal limit switch mounted to the heat sink and configured to cut off power to the LED chip if a sensed temperature of the heat sink exceeds a temperature set point to thereby provide thermal protection to the LED chip.
