Abstract:
1. A light emitting diode (LED) module, illuminating under application of an electrical current for use in an electrical device as a light source, the LED module comprising: a heat dissipating substrate, having plural electrode sets, each of the electrode sets including an p-type electrode and an n-type electrode, the p-type electrodes electrically connecting to one another and extending to a first edge of the substrate to reach a p-type junction, the n-type electrodes connecting to one another and extending to a second edge of the substrate to reach an n-type junction; and a plurality of epitaxy chips, each having an upper illuminating surface, each of the electrode sets being attached to a lower surface of each of the epitaxy chips, the epitaxy chips electrically connecting to one another via the electrode sets to form a LED module which illuminates with a large illuminating area.
