Abstract

The invention discloses a deep-ultraviolet light source and an encapsulating method thereof. The deep-ultraviolet light source comprises a deep-ultraviolet light-emitting diode and a mounting bracket, wherein the deep-ultraviolet light-emitting diode is fixed on the mounting bracket; a transparent protective medium layer is arranged on the outer part of the deep-ultraviolet light-emitting diode; the transparent protective medium layer is formed with a bump structure on the end surface of the deep-ultraviolet light-emitting diode; the transparent protective medium layer is formed with a sunken structure on the end surface of the deep-ultraviolet light-emitting diode. The bump transparent protective medium layer is formed on the end surface of the deep-ultraviolet light-emitting diode, and the sunken transparent protective medium layer is formed on the end surface of the deep-ultraviolet light-emitting diode, so that deep-ultraviolet loss, caused by total reflection, of the side surface and the positive end surface can be effectively improved, the ultraviolet radiation dose is increased, and the light-transmitting efficiency of the deep-ultraviolet light source is improved. Besides, the transparent protective medium layers are adopted to protect the deep-ultraviolet light-emitting diode without adopting a quartz lens, so that the encapsulating cost is effectively reduced.

Description

technical field [0001] The invention relates to an ultraviolet light source, in particular to a deep ultraviolet light source and a packaging method thereof. Background technique [0002] The killing effect of external rays on bacteria and viruses is generally completed within a few seconds, while it takes more than 20 minutes for the traditional chlorine and ozone disinfection methods to achieve the effect of ultraviolet rays. Ultraviolet disinfection technology has the highest bactericidal broad-spectrum among all disinfection technologies, and it has a high-efficiency killing effect on almost all bacteria and viruses. However, the ultraviolet light source is very scarce, and the ultraviolet light source commonly used at present is mainly a mercury lamp. With the advancement of technology, deep ultraviolet light-emitting diodes have low power consumption, long life, and no pollution. Compared with mercury lamps, the wavelength of deep ultraviolet light-emitting diodes ca...
