Problems solved by technology

With such a structural design, the LED packaging structure has a transparent layer, LED tube chip, rigid substrate and flexible substrate in the vertical direction. The heat generated by the LED chip needs to go through the two-layer structure of the rigid substrate and the flexible substrate. It can be transferred to the outside, and it is difficult to effectively conduct heat from the bottom of the LED packaging structure, resulting in poor heat dissipation efficiency

Description

technical field [0001] The invention relates to a light emitting diode packaging structure and a manufacturing method thereof, in particular to a flexible light emitting diode packaging structure and a manufacturing method thereof. Background technique [0002] Light-emitting diodes are energy-saving, environmentally friendly, and long-life solid-state light sources. Therefore, the research on light-emitting diode technology has been very active in the past ten years, and light-emitting diodes are gradually replacing traditional light sources such as fluorescent lamps and incandescent lamps. [0003] According to actual needs, flexible light-emitting diode packaging structures are often used in lighting products. In the existing flexible LED packaging structure, the LED chip with a rigid substrate is often covered by a flexible substrate, only the LED chip is exposed, and then the LED chip is covered by a transparent layer to achieve a flexible effect. With such a structura...
