Problems solved by technology
[0003] At present, the manufacturing process of matrix light-emitting diodes first sets a plurality of openings on a substrate, and then sets a light-emitting diode chip in each opening. The positive / negative poles of each light-emitting diode chip are wired. It is connected to the positive / negative electrodes set on the substrate. However, when setting the matrix light-emitting diodes to the control circuit board, for example: when using the matrix light-emitting diodes as lighting equipment, it must be soldered. The positive / negative poles of the matrix light-emitting diodes are electrically connected to the control circuit board. Because the welding method is time-consuming, it has the problem of low installation efficiency, and the conventional matrix light-emitting diodes are not easy to dissipate heat, so the matrix light-emitting diodes The high heat generated by the diodes during use is not easy to eliminate, which will easily lead to a reduction in the service life of the light-emitting diodes

Description
Technical field: [0001] The invention relates to a matrix light-emitting diode and a manufacturing method thereof, which are convenient for assembly and use and improve the efficiency of assembly and use. Background technique: [0002] Today, the electricity used for lighting in the world accounts for about 40% of the total electricity consumption, which shows people's demand for lighting. However, besides lighting, electricity still needs to be developed for other more important purposes. Therefore, how to develop economical, effective and environmentally friendly The power supply is a technology that the whole world is eager for; but before this technology has not broken through, I am afraid that only saving electricity is an important and effective measure of electricity consumption. In recent years, the technology of light-emitting diodes has advanced by leaps and bounds. It is not a dream to replace today's lighting equipment with light-emitting diodes in the future. At...
