Problems solved by technology

However, this will increase the manufacturing process cost and difficulty of LED 1
During the encapsulation process of the photodiode 1, the photodiode 1 is generally pasted on the bracket through silica gel, and the light emitted by the light-emitting diode 1 is emitted through the light-transmitting protective layer 3 (usually a lens). Since the bracket is opaque, light is emitted from one side after packaging. The light-emitting angle of the light-emitting diode 1 is limited to about 110°, and it is impossible to perform full-angle 360° illumination

Abstract

The invention provides a light-emitting diode, a package substrate structure and a packaging method. The connection end of a P-type electrode of the light-emitting diode and the connection end of an N-type electrode of the light-emitting diode are installed at the same end. Meanwhile, a slot is formed in the package substrate structure, and connection metal is installed in the slot. When packaging is carried out, the end, provided with the connection ends, of the light-emitting diode is inserted in the slot in the package substrate structure, a routing process is omitted, and meanwhile 360-degree light emitting of the light-emitting diode can be achieved. No DBR structure is needed, and the process complexity is reduced.

Description

technical field [0001] The invention relates to the field of light-emitting diode manufacturing, in particular to a light-emitting diode, a packaging substrate structure and a packaging method. Background technique [0002] LED (Light-Emitting Diode, light-emitting diode) devices based on GaN (gallium nitride) materials have been widely used in production and daily life, and are mainly used to emit blue light and green light. LED devices based on GaN materials usually use N-type doped GaN, InGaN (indium gallium nitride) quantum wells and P-type doped GaN. After biasing at both ends, P-type doped GaN provides hole carriers. , N-type doped GaN provides electron carriers, electrons and holes flow in reverse, and recombination occurs in the InGaN quantum well, thereby emitting light of a certain wavelength. Among the many factors that affect the luminous efficiency of the device, the metal electrodes at both ends used for voltage application should form a good ohmic contact wit...
