The invention discloses a hybrid wavelength ultraviolet (UV) light-emitting diode (LED) light source device for solidifying traditional UV printing ink. The hybrid wavelength UV LED light source device comprises packaged hybrid wavelength UV LED modules which are arranged in a shell body and connected with a metal circuit board radiator. Each packaged hybrid wavelength UV LED module is formed by a substrate, wafers arranged on the substrate, and a primary light distribution lens for sealing the wafers. The packaged hybrid wavelength UV LED module further integrates and packages a secondary light distribution lens. Each hybrid wavelength UV LED module is formed by a UV-365NM wafer, a UV-385NM wafer and a UV-395NM wafer in an integrated and packaged mode according to the proportion of 1:1:2. A radiating cold plate is formed by a metal circuit board with heat dissipation fins and a cover plate in a press fit mode. Two coolant inlets and two coolant outlets are arranged in the cover plate. The hybrid wavelength UV LED light source device solves the problems of hybrid wavelength selecting and proportioning in solidifying the traditional UV printing ink, reduces thermal resistance from an LED module unit to the radiating cold plate, avoids the problems that light effects and service life of chips are unbalanced due to uneven junction temperature of LEDs, and improves temperature uniformity of the cold plate, uniformity of light spots of a light source and utilization rate of light energy in the radiating process.
Description
technical field [0001] The invention relates to an LED light source, more specifically, to a mixed-wavelength UV LED light source device for curing traditional UV inks. Background technique [0002] UV LED light source technology has gradually matured in the application of UV glue curing, among which many Chinese and foreign companies are developing and many products have come out. [0003] When the UV LED light source is curing the ink, the supporting ink must be a special ink for LED, and the traditional UV ink cannot be used. However, because the traditional UV ink is very mature, the traditional UV ink is cured by UV Lamp (mercury lamp). Therefore, how to use UV LEDs to replace traditional mercury lamps with a suitable ratio to achieve a good effect of curing traditional UV inks has become an important research topic for those skilled in the art. [0004] In the known general prior art, a single wavelength is mostly used: such as a single 365NM, or 385NM, or 395NM ligh...
