    摘要

  • 与汞灯相比，紫外LED波长单一，不能与现有紫外油墨的光引发剂完全兼容，难以实现汞灯的固化效果。本文给出了一种多波长均匀混合的紫外LED油墨固化系统设计方法。将三种波长的紫外LED在弧面上排成阵列，采用光学自由曲面，使每颗LED灯珠均匀照射固化区域，结合照明角度倾斜变化，解决了波长均匀混合与照度均匀技术难题。光线追迹仿真结果表明，在距光源600 mm的目标面上得到了波长混合均匀，平均照度为110.7 mW/cm2，照度均匀性为0.82的照明光斑，该设计有望模拟汞灯的多光谱照明效果，促进紫外LED在油墨固化中的应用。

    Compared with mercury-vapor lamp, ultraviolet (UV) LED suffers from the disadvantage of having a single wavelength, which is not fully compatible with the existing photoinitiator of ultraviolet ink. It is difficult using UVLEDs to achieve the curing effect comparable to what mercury-vapor lamp can do. This article presents a design of UVLED ink curing system that provides evenly mixed light with multiple wavelengths. We put a UVLED array with three wavelengths on a cambered surface and achieved uniform illumination in ink curing area by using optical freeform surface. By adding the adjusting of the tilt angle, we solved the dilemma of uniform wavelength mixing and uniform illumination. The ray tracing simulation results show that an illumination spot with uniform wavelength mixing, an average illumination of 110.7 mW/cm2, and an illuminance uniformity of 0.82 is obtained on a target surface 600 mm away from the light source. This design is expected to simulate the multi-spectral illumination effect of mercury-vapor lamps, which can promote the application of UVLEDs in ink curing.

    • Overview

  • Overview: Ultraviolet light emitting diode (UV-LED) with the advantages of small volume, high luminous efficiency and long life, shows a good prospect in replacing the traditional mercury lamp for the ink curing. At present, there have been many researches on UV-LED light source array, which mainly focus on how to improve the uniformity and illuminance of the spot formed by LED array on the target surface, and use secondary light distribution design to optimize. However, these researches are all aimed at UV-LED of single wavelength, and obtain curing spot that meets demand by theoretically calculating the arrangement spacing and number of LEDs. The ink for traditional UV curing is all matched with the spectrum of mercury lamp, but the curing effect of UV-LED with single wavelength and narrow spectrum is often different from mercury lamp, so the curing effect is unsatisfactory, which block the spread of UV-LED in ink curing. In present, the central wavelength of commercial UV-LED covers the main UV spectra of mercury lamp. The wavelength range is from 250 nm to 435 nm, and the absorption bandwidth of the photoinitiator is large. In theory, combining UV-LEDs of multiple wavelengths is a feasible way to solve the problem of unsatisfactory single-wavelength UV-LED curing effect. Based on this idea, this paper presents a design method of arrayed multi-wavelength UV LED ink curing system and applies it to the design of three-wavelength UV LED ink curing system. A freeform lens is used to even the light of the LED, and the technical problems of uniform wavelength mixing and uniform illumination are solved by the design of freeform lens and its tilt. The designing steps are as follows: firstly, a freeform lens should be designed to form uniform illuminance distribution for single LED, and then the total number of demanded LEDs is determined according to the required illuminance. Finally, each LED and its homogenization lens are arrayed on the curved substrate. The final entity is shown in the figure. The ray tracing simulation results show that an average illuminance of 110.7 mW/cm2 and an illuminance uniformity of 0.82 are obtained on a target surface 600 mm away from the light source. This method is not limited to the use of three wavelengths and is expected to solve the problem that UV-LED in ink curing cannot be fully compatible with existing photoinitiators of UV inks. It is also expected to promote the application of UVLEDs in ink curing by this study.
