A novel system mainly consisting of multipath controllable constant current source
UV LED spatial array and optical system for UV curing source with LED array was presented.Among them
UV LED spatial array is used to increase the radiation and uniformity of the source. Based on analyzing the UV curing source structure
an optical system was designed. The design method and several design cases
and simulations for optical system with the Light Tools software were also presented. Experimental results show that UV irradiance of the LED spatial array source designed by this method can reach 200 mW/cm
2
and the radiation in the radiating area maintains even and stable
which can meet the needs for source in UV curing process.
