Led light frame system including change-out system for led removal and replacement

Abstract

An illumination system for creating a field of light with which the density, photometric angular distribution, of the projected light can be changed, including a series of light modules including at least one LED, a structural frame of structural rails having electrically insulating elements, within which electrical conductors pass. The structural rails are at least partially composed of a heat conductive material. There is a circuit board which has a heat conductive substrate having slots disposed about the circuit board, and including at least two electrical contact surfaces located along the slots on the circuit board. The LED is mounted to the circuit board which includes at least two electrical contact surfaces located along the slots. There are electrically conductive screws for electrically connecting the LED on the circuit board to the electrical conductors and constructed and arranged to simultaneously provide a thermal transfer from the heat conductive substrate to the structural rails. The screws have a threaded portion of such diameter that they fit within the slots of the circuit board and the heads of the screws have a larger diameter than the slots and make contact with the contact surfaces when the screws are tightened.
