Description

technical field

[0001] The invention relates to a light-emitting element, in particular to a light-emitting element with a metal matrix composite material carrier. Background technique

[0002] Light emitting devices are widely used, for example, in optical display devices, laser diodes, traffic signs, data storage devices, communication devices, lighting devices, and medical devices.

[0003] Traditional light-emitting elements are mainly made of semiconductors, which have poor thermal conductivity. When the light-emitting element is powered on, the light-emitting element emits light, which will generate heat. Since the light-emitting element is made of semiconductor material, the heat conduction is not good. If the heat cannot be removed properly, the light-emitting element will reduce the luminous efficiency due to heat. , For materials composed of AlGaInP, under the same current conditions, when the external temperature rises from 20°C to 80°C, the brightness will drop ...
