不同調(diào)光方式LED照射下的人體非視覺效應
[Abstract]:Analog dimming and PWM dimming are used to realize LED light regulation respectively. Using physiological parameter method and taking college students as research objects, three kinds of color temperature (3 000 ~ 5 600 ~ 6 300500800 K) LED) light source were selected and 8 cases (5 males) were selected under three illuminance (300500800 lx) level. The pulse and pupil of the subjects were measured before and after the experiment. Using the same three color temperature LED light sources, the pulse and pupil of 12 subjects (8 males and 4 females) were measured before and after the experiment by adding blue light (464 nm ~ 20 lx) to realize the lighting environment of 300 lx. The results showed that there was no significant difference in the effect of LED light environment between the two dimming modes on the pulse rate and pupil contraction rate. Adding blue light to the test lighting environment can increase the pulse rate and pupil contraction rate, and increase the peak value by about 6% and 9%, respectively.
