Abstract
A recessed LED light fixture without need for a bulky, finned, metal heat sink. The recessed LED light fixture includes a Metal Core Printed Circuit Board (MCPCB) holding an array of LEDs that are arrange at the center thereof, and mounted to the printed circuit board using patterns of electrical and thermal conductors used to conduct a current and radiate heat. A mounting bracket holds the entire assembly for the light fixture together while spacing the LED driver and printed circuit board apart for further cooling, and wherein the upper side of the printed circuit board is exposed to the ambient air inside the housing.
