Abstract

The high-brightness light-emittnig bipolar body includes one seat plate, one compound crystal light-emitting bipolar body crystallite with transparent base plate and one covering plate. The covering plate has one central hole with inclined side wall and the light-emitting bipolar body crystallite is held inside the hole. The seat plate is divided into two parts by one middle insulating area and the two parts are connected separately to two electrodes of the light-emitting bipolar body crystallite. The seat plate is made of matter with high heat conductivity and high electric conductivity for conducting great current and dissipating heat. The central hole is filled and the light-emitting bipolar body crystallite is packed with transparent resin or epoxy resin. The present invention can emit high-strength light.

Description

technical field

[0001] The invention relates to a light-emitting diode, in particular to a high-brightness light-emitting diode with flip-chip light-emitting diode grains. Background technique

[0002] Due to low power consumption, small size, and long service life, light-emitting diodes are currently widely used in home appliance audio indicator lights, mobile phone backlights, light-emitting diode signage, and third brake lights for cars. In recent years, due to the successful development of new light-emitting diode materials such as aluminum gallium indium phosphide (AlGaInP) and indium gallium aluminum nitride (AlGaInN), the brightness of light-emitting diodes can be further improved, so it can be used in many In application, light-emitting diodes are used to replace traditional incandescent bulbs. At present, visible light-emitting diodes are used in applications such as traffic lights, automobile tail lights, and direction lights. In the future, with the improvement ...
