specifically to this problem, LED chip refers to the core component of LED, which is called light emitting diode in Chinese, and consists of a PN junction with corresponding electrodes and structural parts. But this chip can't be used directly, on the one hand, because it is very small, and on the other hand, because it can only emit light of several colors. Therefore, it is necessary to further process the LED chip, that is, LED packaging. Packaging is to fix the LED chip on a specific bracket, which can not only satisfy the heat dissipation of the chip, but also electrify the chip. In this way, the packaged LED can be directly powered on.
packaging will also involve many patent issues. for example, the blue chip excites yellow phosphor to produce white light, which is a patented technology of Japan Asia.
