摘要
瞳孔面积变化是人眼应对外界刺激的重要表现形式之一。目前,国内外相关道路照明设计标准中规定的路面亮度指标是客观(物理)亮度,但由于眩光的存在,相同客观路面亮度给予驾驶员的主观亮度感受并不一致。基于瞳孔面积变化与主观亮度之间的关系,通过实验揭示出瞳孔面积与眩光、客观路面亮度之间的数值关系,提出在保持驾驶员相同主观亮度的条件下,采用削减眩光、降低阈值增量,从而大幅度降低路面亮度设计值的方法,为道路照明节能提供了新的途径。
Pupil area change is one of the important manifestations of the human eyes’ response to external stimuli. At present, the road surface brightness index, specified in the CIE and CJJ 45 lighting design standards, is objective (physical) brightness. However, due to the glare of road lights, the driver’s subjective perceived brightness is inconsistent under the same objective road surface brightness. On the basis of the relationship between pupil area change and subjective brightness, the numerical relationship among pupil area, glare and objective road surface brightness is revealed after the experiments. It is proposed to greatly reduce the design value of the road surface brightness by reducing the glare and the TI value under the condition of the same subjective brightness of the driver, which provides a new way for road lighting energy saving.
