Abstract
An LED package comprises a substrate, one or three terminals formed on a first side of the substrate, three terminals formed on a second side opposite to the first side, and two or three LEDs disposed on the substrate, one of the LEDS being electrically connected to one of the terminals formed on the first side while being electrically connected to one of the terminals formed on the second side, and other LEDS being electrically connected to two terminals formed on the first side or to two terminals formed on the second side. A light source comprises the LED packages having the structure as described above. Without being arranged in a line, the LEDs emitting the same color are differently arranged in every LED package, thereby solving the problem of non-uniform combination of the colors according to the positions of the LEDs on an LED package-mounting substrate.
