Abstract

The ocular movement characteristics to LED lights with high luminous intensity were explored when viewing such LED lights using a belt conveyer equipped with such LED light with high luminous intensity. The ocular movement characteristics such as blink duration, blink frequency, and PERCLOS70 were investigated as a function of LED color and luminous intensity. The blink duration consistently tended to increase with the increase of luminous intensity for all colors of LED. The blink frequency tended to increase under the high luminous intensity for both red and white LED which have higher wavelength. As for green LED, the blink frequency was not affected by the luminous intensity. Contrary to the case of red and white LED, the blink frequency of blue LED tended to decrease under the high luminous intensity. PERCLOS70 of red, white, and green LEDs tended to increase with the increase of luminous intensity. In this manner, the ocular movement characteristics of blue LED could be indicated.
