摘要
2002年以前,人们曾经简单地利用直接光内光外透照明方式来装饰玻璃幕墙外立面,不可避免地产生了眩目和光污染。2002年以后,间接光内光外透照明方式成为一种玻璃幕墙外立面装饰照明的解决方案:当玻璃幕墙建筑物的外立面由玻璃幕墙和与其平行的内衬反光膜组成,在其间又配置照明装置时,照明装置既可以对反光膜平行投光,也可以对反光膜垂直投光,反光膜产生透射和漫反射,使玻璃幕墙外立面成为清晰、柔和的发光面,使玻璃幕墙建筑物成为不眩目、不产生光污染的发光体,实现绿色照明。当前,新出现一种玻璃幕墙大厦外立面上LED灯具外设、组成彩色图案并动态变化的装饰照明方式,让玻璃幕墙外立面变成巨型显示屏,在获得装饰照明效果的同时,又产生了眩目和光污染,影响人们的身心健康。
Before 2002,the facade of glass curtain wall was simply lighted by the directive lighting from interior lights,but it inevitably caused glare and light pollution. Since 2002,the indirect lighting from interior lights has become a green solution in decorative lighting of facades of glass curtain walls: When an internal membrane which has reflection functions and is parallel to the glass curtain wall,and there is some lighting device located between the membrane and the glass,the lighting device emits lights to the membrane in the direction of parallel or vertical,finally the light reflected from the membrane and runs out the glass curtain wall is indirect light without any glare and pollution. Recently,another decorative lighting method with colorful and exchangeable pictures on the glass curtain wall comes from linear LED luminaires located on the surface of the glass curtain wall. In fact,the method lets the fa? ade of glass curtain wall become a huge display screen,but inevitably causes glare and pollution again,and affects the health of human being.
