Abstract

The invention discloses an ultraviolet LED light source device. The ultraviolet LED light source device comprises an LED light source module and a heat dissipation module; the LED light source modulecomprises a substrate and an LED light source unit, wherein the LED light source is arranged on the substrate and is arranged in an array mode, and the substrate is arranged on the heat dissipation module; and the device further comprises an oxygen-free gas source, wherein the oxygen-free gas source is used for blowing oxygen-free gas to the irradiation surface of the LED light source module, andan oxygen-free environment is manufactured on the irradiation surface of the LED light source module. According to the ultraviolet LED light source device, due to the fact that the oxygen-free gas source is arranged, when ultraviolet light is irradiated, the oxygen-free gas source blows oxygen-free gas to the irradiation surface, the oxygen concentration in the upper space of the irradiation surface can be diluted, the oxygen concentration can be reduced to a very low degree through continuous blowing, and therefore the oxygen-free environment can be formed; and due to the fact that ultraviolet rays irradiate on the irradiation surface, ozone cannot be generated in the oxygen-free environment, so that the quality of ultraviolet irradiation curing is guaranteed.

Description

technical field [0001] The invention relates to an LED light source, in particular to an ultraviolet LED light source device. Background technique [0002] Ultraviolet light LED light source devices are mostly used in processes that adopt ultraviolet light irradiation and curing, such as photolithography curing and printing curing processes. [0003] Because ultraviolet rays can cause the ionization of oxygen in the air, ozone is produced. The activity of ozone is higher, and ozone will be generated in the area where the ultraviolet energy gathers, that is, the ultraviolet irradiation surface, and this is the area where the cured material is located. In some processes, such as printing processes, some printing materials will be oxidized by ozone, resulting in a lower printing pass rate. Ozone also absorbs and blocks UV rays, making UV energy exposure less effective. [0004] In addition, in the printing process, the ultraviolet LED light source usually needs to provide a ...
