Document Type and Number:
Japanese Patent JPH1012010
Kind Code:
A
Abstract:
To reduce the amount of illumination light projected onto a computer display.
A computing part 11 built into a computer 1 computes the intensities L1, L2 of projected light on the basis of the brightness W1, W2 of luminaires 2, 3, the incidence angle of light on a display 13, and a material covering the tube surface of the display 13, and a control part 12 compares the L1, L2 with a preset threshold and issues a control signal based on their difference to control volumes 6, 7 to adjust the brightness of the luminaires 2, 3.
