Abstract
An LED device comprises a substrate, a circuit, two LED dies, a dam and a reflector. The dam divides the substrate into a first area and a second area, wherein one of the two LED dies is disposed on the first area and the other is disposed on the second area. The dam insulates radiant lights emitted from the two LED dies, whereby interference between the radiant lights can be prevented. Four separate electrodes are provided on the substrate, wherein one LED die is connected to two electrodes and the other LED die is electrically connected to the other two electrodes.
