Description

technical field [0001] The present invention relates to a light-emitting diode (Light-Emitting Diode; LED) and a manufacturing method thereof, in particular to a point-source light-emitting diode with improved crystal surface appearance and a manufacturing method thereof. Background technique [0002] A light-emitting diode is a p-n junction diode that can naturally emit light of different wavelengths. Because light-emitting diodes have good photoelectric characteristics such as low power consumption, low calorific value, long service life, impact resistance, small size, fast response speed, and can emit color light with stable wavelengths, they are often used in home appliances, indicator lights of instruments, photoelectric The application of the product is in the field of light source and optoelectronic communication. [0003] Due to the high reliability of light-emitting diodes and the large ratio of light coupling into fibers, they have become important active componen...
