摘　　要：为了将灯具罩上的印花变为可动态变化,引用建筑领域的电控调光玻璃幕材料。电控可调光玻璃幕两片玻璃里夹的是聚合物分散液晶(PDLC),通过夹胶复合在两片玻璃中间,利用液晶的特性,只需对电源进行电压控制,便可使玻璃由透明瞬间转成不透明或由不透明瞬间转成透明。实验通过利用PDLC材质的特性,再加上灯罩常用的PC印花灯罩,结合特殊电路与结构光学的设计,实现使用者可以感觉到灯具上的印花在动态变化。This paper mainly studies how to change the printing on the lamp cover into dynamic change,by citing the electrically controlled dimming glass curtain material in the field of architecture.In the electrically controlled dimming glass curtain,the polymer dispersed liquid crystal(PDLC)is sandwiched between two pieces of glass,by sandwich composite in the middle of two pieces of glass.By using the characteristics of liquid crystal,the glass can be changed from transparent to opaque or from opaque to transparent instantly by voltage control on the power supply.The experiment shows that by using the characteristics of PDLC material and PC printing lampshade commonly used,combined with the design of special circuit and structural optics,users can feel the printing on the lamp changing dynamically.
