Problems solved by technology

In other words, due to the fact that the length l1 of the base S1 is too short, the conventional LED chip D will not be able to obtain effective heat dissipation, and the LED chip D will burn out due to overheating.
[0005] Therefore, it can be seen from the above that the current packaging methods and packaging structures of light-emitting diodes obviously have inconveniences and shortcomings, and those that need to be improved

Abstract

The invention relates to a light-emitting diode chip packaging structure with high-efficiency lateral lighting effect. The structure comprises a base plate unit, a light-emitting unit, a package colloid unit and a frame unit, wherein, the light-emitting unit comprises a plurality of light-emitting diode chips which are electrically arranged on the base plate unit. The package colloid unit comprises a stripe package colloid covering the light-emitting diode chips, wherein, a colloid arc surface and a colloid light-exiting surface are arranged on the upper surface and the front surface of the stripe package colloid respectively. The frame unit adopts a frame layer covering the base plate unit and coating the stripe package colloid, and only the colloid light-exiting surface is exposed.

Description

technical field [0001] The present invention relates to a packaging method of a light-emitting diode chip and its packaging structure, in particular to a packaging method of a light-emitting diode chip with a high-efficiency lateral light-emitting effect (high-efficiency lateral light-emitting effect) and its packaging structure. Background technique [0002] see figure 1 As shown in FIG. 1 , it is a flow chart of an existing packaging method for light emitting diodes. It can be known from the flow chart that the steps of the existing LED packaging method include: firstly, providing several packaged LEDs (packaged LED) (S800); then, providing a stripped substrate body, on which There is a positive electrode trace (positive electrode trace) and a negative electrode trace (negative electrode trace) (S802); finally, each packaged light-emitting diode (packaged LED) is arranged on the strip substrate body in sequence, and The positive and negative terminals of each packaged LE...
