An application research on the high power 365nm UV LEDs widely used in the field of UV curing was performed,and a technical method using a two-dimensional array arrangement was suggested to realize the accumulation of their energy.The principle of optimum designing and an emulation software were provided.The emulating results exhibit the feasibility of the optical two-dimensional-array design scheme,which can reach many requirements in practical applications,including the irradiance intensity,the size and profile of spots,and the back-working distance.According to technical requirements occurred in a practical application case,the proposed system can provide a line-type irradiance spot of 50×10 mm2,a back working distance of more than 50mm,and an irradiance intensity of more than 1000 mW/cm2.And the proposed optical two-dimensional-array design scheme is convinced of an optimum designing in the configuration side of optical system.
