LED lighting device and system

A lighting system for illuminating the interior of a vehicle, aircraft or building, the lighting system comprising:

• a plurality of lighting devices, the lighting devices comprising:
• a channel case made from a thermally conductive material, the channel case comprising:
• a bottom edge;
• and
• two opposed side edges;
• wherein the bottom edge and the two opposed side edges form an elongated box further forming an interior space;
• at least one circuit board disposed within the interior space of the channel case, wherein the at least one circuit board includes top and bottom sides and includes circuit traces;
• a heat transfer device coupled to the at least one circuit board and the channel case, the heat transfer device transferring heat to the channel case;
• a plurality of light emitting diodes (LEDs) mounted on the at least one circuit board and electrically connected to the circuit traces;
• a plurality of resistors mounted on the at least one circuit board and electrically connected to the circuit traces;
• a lens attached to the two opposed side edges of the channel case;
• end caps attached to both ends of the channel case;
• electrical connectors coupled to the circuit traces of each lighting device, the electrical connectors of the plurality of lighting devices fastening to the other electrical connectors of the plurality of lighting devices;
• and
• wherein the lens applies a force to the at least one circuit board, compressing the heat transfer device disposed between the at least one circuit board and the bottom edge of the channel case.
