Light-emitting diode light bar

Abstract

In a light-emitting diode light bar of a light-emitting device, a first lead and a second lead are juxtaposed with a distance. A light-emitting diode crystal has a first electrode and a second electrode. Then, the first electrode is electrically fixed to the first lead. The second electrode is electrically connected to the second lead via a metallic lead. A light-transmitting body is used to package the light-emitting diode crystal and the metallic lead. Finally, via a hot pressing process, an insulating layer covers the first lead and the second lead. In this way, a light-emitting diode light bar is formed.
