Abstract

A surface mounted LED light structure has a V-shaped channel with opposed legs and a flat central portion. A flat base strip is attached to each leg. The strips each have a pair of electrically conductive traces. A plurality of LEDs is arrayed along the base strips and electrically connected to the traces. A diffuser is disposed over the LEDs. A spacer sleeve holds the diffuser over the channel central portion. A driver is mounted adjacent the channel and is connected to the conductive traces and to the power source.

Claims

1. A surface mounted LED light structure, for use in connection with an electrical power source and a driver operatively electrically connected to the power source, the light structure comprising:

a channel having a trough-shaped cross section extending between opposite first and second ends along a central plane, the cross section having bilateral symmetry about the central plane, the cross section having a generally flat central portion generally perpendicular to the central plane, the cross section having opposite generally flat left and right legs extending outward on either side from the central portion, the left and right legs each having an outer surface facing away from the opposite leg and an inner surface facing toward the opposite leg;

a first base strip, the first base strip being generally flat and elongated, the first base strip being electrically nonconductive, the first base strip having a pair of electrically conductive traces operatively electrically connected to the driver, the first base strip being attached to the channel left leg;

a second base strip, the second base strip being generally flat and elongated, the second base strip being electrically nonconductive, the second base strip having a pair of electrically conductive traces operatively electrically connected to the driver, the second base strip being attached to the channel right leg;

a plurality of LEDs arrayed in a linearly spaced relation along the first and second base strips, the LEDs being operatively electrically connected to the conductive traces;

attaching means for attaching the first and second base strips to the channel;

a diffuser juxtaposed with, and spaced from, the channel and disposed over the LEDs for diffusing light emitted by the LEDs;

a plurality of spacer sleeves each having a central hole therethrough and disposed between the diffuser and the central portion, the spacer sleeves being located between, and spaced from, the first and second strips and being spaced along the length of the central portion; and

a plurality of threaded fasteners extending through the diffuser, through the spacer sleeve central holes, and through the central portion,

wherein, the diffuser is in pressing contact with the spacer sleeves and secured to the channel by the threaded fasteners, the diffuser being secured to the channel solely by the threaded fasteners.

2. The surface mounted LED light structure of claim 1, further comprising:

the first base strip and respective LEDs being attached to the channel left leg outer surface; and

the second base strip and respective LEDs being attached to the channel right leg outer surface.

3. The surface mounted LED light structure of claim 1, further comprising:

the first base strip and respective LEDs being attached to the channel left leg inner surface; and

the second base strip and respective LEDs being attached to the channel right leg inner surface.
