已经假设具有较高辐照度的脉冲蓝光的光具有比具有较低辐照度的稳定蓝光的光大得多的影响，尽管它们具有相同的辐照度和持续时间的倍增值。我们研究了蓝色脉冲光的非视觉生理效应，并确定它是否被视觉感知为蓝色。7名年轻男性志愿者参与了这项研究。我们在参与者面前放置了一个圆形屏幕（直径500 mm），并使用蓝色和/或白色发光二极管（LED）对其进行照射，我们使用卤素灯作为标准光源。我们应用了白色LED（F0）、蓝色LED +白色LED（F10）和蓝色LED（F100）的三种稳定光条件，以及脉冲宽度为100 μs、占空比为10%的蓝色脉冲光条件（P10）。在参与者眼睛水平的所有四种条件下的辐照度几乎相同，约为12 μW/cm 2。我们测量他们的瞳孔直径，记录脑电图读数和关西学院嗜睡量表评分，并收集主观评价。F100条件下的主观发蓝评分显著高于其他条件下的主观发蓝评分。即使在蓝色脉冲光占空比为10%的P10条件和F10条件下，参与者也没有感觉到光是蓝色的。P10脉冲光条件下的瞳孔光响应显著大于F10条件下的瞳孔光响应，即使这两种条件具有相等的蓝光分量。瞳孔在蓝色脉冲光条件下收缩，表明照明的非视觉效果，即使参与者没有感知到蓝色的光。
It has been assumed that light with a higher irradiance of pulsed blue light has a much greater influence than that of light with a lower irradiance of steady blue light, although they have the same multiplication value of irradiance and duration. We examined the non-visual physiological effects of blue pulsed light, and determined whether it is sensed visually as being blue. Seven young male volunteers participated in the study. We placed a circular screen (diameter 500 mm) in front of the participants and irradiated it using blue and/or white light-emitting diodes (LEDs), and we used halogen lamps as a standard illuminant. We applied three steady light conditions of white LED (F0), blue LED + white LED (F10), and blue LED (F100), and a blue pulsed light condition of a 100-μs pulse width with a 10% duty ratio (P10). The irradiance of all four conditions at the participant's eye level was almost the same, at around 12 μW/cm2. We measured their pupil diameter, recorded electroencephalogram readings and Kwansei Gakuin Sleepiness Scale score, and collected subjective evaluations. The subjective bluish score under the F100 condition was significantly higher than those under other conditions. Even under the P10 condition with a 10% duty ratio of blue pulsed light and the F10 condition, the participant did not perceive the light as bluish. Pupillary light response under the P10 pulsed light condition was significantly greater than under the F10 condition, even though the two conditions had equal blue light components. The pupil constricted under the blue pulsed light condition, indicating a non-visual effect of the lighting, even though the participants did not perceive the light as bluish.
