摘要(Abstract):

依据CIE 150号出版物中的阈值增量(TI)的计算公式,推导了在理想道路和调光情况下不同人眼适应亮度时TI和光输出变化之间的关系。通过更改路灯配光文件中光输出系数,来模拟可调光路灯在空间各方向上光强均匀变化,运用道路模拟软件计算道路照明的阈值增量,验证推算结果。理论推导和模拟结果表明,在理想条件下灯具调光对阈值增量的影响由于受人眼适应亮度高低而不同,并不随着路灯光输出的改变而单调地改变。
According to the threshold increment(TI) formula in CIE 150 technical report, the relationship between TI and the change of light output is derived with different value of adaptation luminance under ideal road and dimming conditions. By changing the coefficient of light output in the light distribution file of a streetlight, we simulate an ideal dimming style characterized with proportional luminous intensity change in all directions. The threshold increment of road lighting is calculated by using road simulation software to verify the derived results. Theoretical derivation and simulation results show that under ideal conditions, the influence of dimming on threshold increment varies with the adaptation luminance, and does not change monotonously with the light output of streetlight.
