Problems solved by technology

[0002] When electronic products are in operation, the current in the circuit will generate unnecessary heat energy due to flowing through the impedance. If the heat energy cannot be effectively removed and accumulated on the electronic components inside the electronic product, the electronic components may be affected by the rising temperature. damage due to temperature
Therefore, the heat dissipation efficiency greatly affects the operation of electronic products.
Especially for light-emitting diodes, when the temperature of light-emitting diodes increases, the luminous efficiency of light-emitting diodes will decrease significantly, and the service life of light-emitting diodes will be shortened

Abstract

A package structure of light emitting diode includes a substrate and a light emitting diode die. The substrate has an upper surface and a lower surface opposite to each other. Two upper metal pads without mutual conduction are arranged on the upper surface. Two lower metal pads without mutual conduction are arranged on the lower surface. The light emitting diode die is disposed across the two upper metal pads. The light emitting diode die has a first electrode and a second electrode electrically connected to the two upper metal pads respectively. Wherein an orthographic projection area of one of the lower metal pads is greater than or equal to an orthographic projection area of the light emitting diode die, and the orthographic projection area of the light emitting diode die is totally located within the orthographic projection area of one of the lower metal pads.

Description

technical field [0001] The invention relates to a packaging structure of a light emitting diode, in particular to a packaging structure of a light emitting diode that can improve heat dissipation efficiency. Background technique [0002] When electronic products are in operation, the current in the circuit will generate unnecessary heat energy due to flowing through the impedance. If the heat energy cannot be effectively removed and accumulated on the electronic components inside the electronic product, the electronic components may be affected by the rising temperature. damage due to temperature. Therefore, the heat dissipation efficiency greatly affects the operation of electronic products. Especially for light-emitting diodes, when the temperature of the light-emitting diodes increases, the luminous efficiency of the light-emitting diodes will decrease significantly, and the service life of the light-emitting diodes will be shortened. As light-emitting diodes are gradua...
