摘　　要：在户外投光广告照明中,均匀度和光能利用效率不高一直是困扰相关设计人员的一个问题。本文从配光曲线基本概念出发,根据光强与照度的基本关系,结合户外投光广告照明的特点,得出了一种实现投光广告均匀照明的方法。在保证足够均匀度的情况下,提高了光能利用率,并对减少光污染提出了一定的建议,对实现中高幅投光广告均匀照明有重要的参考价值。In outdoor urban cast lighting advertisement,uniformity of illuminance and coefficient of energy are the troubles to these persons who are engaged in lamp designing. With the concept of light distribution curve and the basic relationship of light intensity and illumination ,this paper discuss a method which achieves a uniform cast light advertising lighting. Under the condition of highly uiformity of illuminance, this measure can improve the the utilization of light energy ,and it also puts forward some suggestions that can reduce light pollution. Above these ,it has very important reference value to realize more uniform and higher cast lighting.
