Abstract
A light-emitting diode light bar includes a printed circuit board and a light-emitting diode. The printed circuit board has a protective layer, a first signal line, and a first extension line. The LED is disposed on the first signal line and the first extension line. The protective layer is formed above the first signal line and the first extension line, and has an opening that exposes a portion of the first signal line, and a portion of the extension line, such that a first exposed length of the first signal line is substantially equal to a second exposed length of the first extension line.
