Influence of Different Wavelength Blue LED on Human Optical Biorhythm Effect
Human have different sensitivity under different wavelengths of light. By using dose work method
physiological parameter method and fatigue evaluation method
the human optical biorhythm effect of 30 students with normal vision was studied under the blue LED
whose peak wavelengths are 468
457
and 453 nm. In the dose work method
the influence of blue LED on the error rate
speed of work
and the brainwork efficiency is: 453 nm<457 nm<468 nm. In physiological parameter method
468 nm blue LED has the greatest impact on the changes of pulse
and insignificant on systolic/diastolic blood pressure. In fatigue evaluation method
effect of blue LED on human comfort is: 453 nm<457 nm<468 nm. In conclusion
468 nm blue LED has great influence on human optical biological rhythm.
