Inorganic-packaged self-focusing integrated UVLED module

Abstract

The invention discloses an inorganic-packaged self-focusing integrated UVLED module, which comprises a UVLED lamp component, a UVLED chip, an optical light guide plate, quartz glass and a front cover, wherein the UVLED lamp component comprises a copper-based circuit board; the copper-based circuit board is provided with a die bonding region; the UVLED chip is fixed at the middle part of the die bonding region; the optical light guide plate is used for reflecting light of the side surface of the UVLED chip and then ejecting the light through a normal direction of the UVLED chip; the front cover comprises a cover board with a groove structure; a notch of the groove structure is toward one side of the copper-based circuit board; the bottom of the groove structure is the front end surface; a light outlet window is formed in the front end surface; the quartz glass is bonded to the bottom of the groove structure by a sealant and covers the light outlet window; the rear end surface of the front cover is fixedly connected with the copper-based circuit board; a cavity is formed between the groove structure of the front cover and the copper-based circuit board; and the cavity is filled with a protective gas.

Description

technical field [0001] The invention relates to a UVLED lighting module, which is specifically used in the field of ultraviolet lighting. Background technique [0002] At present, LED packaging mostly uses organic materials such as silica gel and epoxy resin to package chips. The device fails, so organic materials are not conducive to encapsulating high-UV LEDs. Therefore, it is very necessary to seek an anti-ultraviolet aging simple inorganic packaging process and its supporting components. [0003] In addition, UV LEDs in industrial applications, that is, ultraviolet LEDs, in order to increase the ultraviolet energy to achieve application effects, the method of splicing lamp beads and the method of UVLED matrix are often used to increase its irradiation energy and irradiation area. The light emitting angle of the lamp bead is generally 120 degrees, and the angle of the LED matrix is ​​generally 140 degrees, so when the light output is relatively scattered, only part of t...

AI Technical Summary

Problems solved by technology

The light emitting angle of the lamp bead is generally 120 degrees, and the angle of the LED matrix is ​​generally 140 degrees, so when the light output is relatively scattered, only part of the ultraviolet light is irradiated in the effective area, and in some working environments with high requirements on the optical path, it may be damaged Other components are affected and cannot meet the requirements of practical applications
