Abstract
One embodiment of a light emitting diode (LED) lighting device comprises multiple LED light sources disposed on multiple elongated circuit boards, with each LED light source being electrically connected to one of the circuit boards. The elongated circuit boards are electrically coupled using electrical passageways to provide power to the circuit boards at intervals along the length of the elongated circuit boards, and the light sources disposed on the circuit boards emit light in the same direction perpendicular to the elongated circuit boards. The electrical passageways can be wires or groups of wires.
