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] The 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 heat generation, long service life, impact resistance, small size, fast response speed, and stable wavelength of color light, they are often used in indicator lights, photoelectric appliances, and meters. The product's application light source and photoelectric communication field. [0003] Due to the high reliability of light emitting diodes and the high rate of light coupling into the fiber, it has become an important active component in optical fiber communication. In order...
