Abstract

An LED cove light system having a wall piece mounted to a back surface of a cove, the wall piece having a top edge which is at the same height as a top surface of a front wall of the cove. A light fixture component is removably attachable at an angle to the wall piece and carries one or more LEDs positioned to project light from the cove out into an adjacent space of a room.

Claims

1. A method of illuminating a ceiling surface located above a cove comprising a rear cove wall and a front cove wall comprising:

constructing a wall piece and configuring the wall piece to be attachable to the rear cove wall;

positioning a plurality of LEDs on a circuit board beneath a light transmissive cover in a light fixture component;

constructing the wall piece and light fixture component to be removably attachable to one another and such that, when attached, the light fixture component and the wall piece interlock such that the circuit board is fixed in position to project light from the cove toward the ceiling surface at a pre-selected fixed angle; and

attaching the wall piece to the rear cove wall and behind the front cove wall at a position selected such that, when the light fixture component is attached to the wall piece, the LEDs of the light fixture component are not visible on a line of sight perpendicular to a vertical wall of a room from a point looking toward the front cove wall, the LEDs are positioned to illuminate the ceiling surface, and each of the LEDs is spaced at the same selected distance from the ceiling surface; and

attaching the light fixture component to the wall piece.

2. The method of claim 1 further comprising configuring and positioning the lamp fixture component such that 85% of the light generated by the LEDs exits the cove.

3. The method of claim 1 further comprising constructing the wall piece entirely out of a non-electrically conductive material.
