Patent ID: 8425085

Claim:
A light-emitting diode (“LED”) based retrofit apparatus for a light fixture, comprising: a bracket configured for attachment to the light fixture; electronics mounted with the bracket, for converting AC line voltage power to low voltage DC power; a first printed circuit board having one or more LEDs mounted thereon, the first printed circuit board mounting with the bracket such that when the first printed circuit board is supplied with the low voltage DC power, the LEDs mounted on the first printed circuit board primarily emit light upwardly into the light fixture, and the light reflects from one or more surfaces and exits the light fixture downwardly; a second printed circuit board having one or more LEDs mounted thereon, the second printed circuit board mounting with the bracket such that, when supplied with the low voltage DC power, the LEDs mounted on the second printed circuit board primarily emit light downwardly with respect to the light emitted from the LEDs mounted on the first printed circuit board; and a diffuser disposed beneath the second printed circuit board, such that light emitted from the LEDs mounted on the second printed circuit board passes through the diffuser, but the light reflecting from the one or more surfaces does not pass through the diffuser.
