摘　　要：采用无极紫外灯作为光源设计了一种新型光敏固化灯具,它克服了传统固化灯具的缺点。光路部分,用机械设计和光学设计等软件对反射罩进行精确的设计和模拟,由紫外光光强分布图看出固化面上的光照均匀度得到很大提高;电路部分,精确设计了无极灯的驱动和控制电路,通过调节高频电路输出功率来改变辐射强度,用反馈装置实现了固化面上的紫外光强度恒定。A new kind of photosensitive curing appliance is designed which uses electrodeless lamp as the UV-light source. This curing appliance has overcome the shortcomings of traditional one. The mechanical design and optieal design software are used to design and simulate the reflector precisely. The simulated UV irradiance map shows the UV light uniformity on the curing surface is greatly improved. An accurate circuit is designed to drive and control eleetrodeless lamp. The UV radiation intensity can be changed by adjusting the output power of high frequency circuit. The feedback device is used to maintain the UV irradiance on the curing surfaee constant.
