Abstract
A light emitting diode device is provided. The light emitting diode device comprises a composite substrate and a light emitting diode disposed on the composite substrate. The composite substrate comprises a first carbon fiber composite layer which is able to conduct heat rapidly in the direction of carbon fiber, such that the heat generated from the light emitting diode module can be dissipated rapidly.
