Abstract

The present invention provides a deep ultraviolet light-emitting device, which relates to the technical field of LEDs. The deep ultraviolet light-emitting device includes a substrate, an optical lens, a sealing gasket, a light-transmitting cover, and at least one deep ultraviolet LED chip, wherein the deep ultraviolet LED chip is welded on the substrate On the first surface, the sealing gasket is arranged on the first surface and surrounds the periphery of the deep ultraviolet LED chip; the optical lens abuts on the side of the sealing gasket away from the substrate; the light-transmitting cover is arranged above the optical lens and abuts against the optical lens , the light-transmitting cover is connected to the substrate, the light-transmitting cover is provided with a light-transmitting part, and the light-transmitting part is aligned with the optical lens. The deep ultraviolet light-emitting device provided by the present invention has a simple structure and tight packaging, and the ultraviolet light emitted by the deep ultraviolet LED chip only needs to pass through the optical lens, so the extraction efficiency of ultraviolet light is high, and the complex structure of the deep ultraviolet LED light-emitting device and the problem of ultraviolet light extraction are solved. The problem of low efficiency.

Description

technical field [0001] The invention relates to the technical field of LEDs, in particular to a deep ultraviolet light emitting device. Background technique [0002] Light Emitting Diode (hereinafter referred to as LED) includes ultraviolet LEDs. Ultraviolet LEDs generally refer to LEDs with a central wavelength of light emission below 400nm. When the light emission wavelength is greater than 380nm, it is called near ultraviolet LED. Ultraviolet light-emitting LEDs have broad application prospects in the fields of sterilization and disinfection, polymer curing, biochemical detection, non-line-of-sight communication, and special lighting. Compared with the traditional ultraviolet light source mercury lamp, deep ultraviolet light-emitting diodes have many advantages such as environmental protection, small and portable, low power consumption, etc., and have received more and more attention and attention. [0003] In a traditional deep ultraviolet light-emitting device, the dee...
