Abstract
A lighting apparatus is configured such that first luminous portions and second luminous portions having different light distribution characteristics are used, and respective luminous intensities of the first luminous portions and the second luminous portions are controlled by a control portion to change the amount of light in the wavelength range inhibiting melatonin secretion which is emitted in a predetermined direction from the first luminous portions and the second luminous portions. As a result, by changing the amount of light emitted in the direction (predetermined direction) toward the eyes of the user in a normal usage mode, the lighting apparatus regulates the amount of the light in the wavelength range inhibiting melatonin secretion which enters the eyes of the user to change the influence on the inhibition of melatonin secretion, and also perform adequate lighting in accordance with time or the lifestyle of the user.

9. A lighting apparatus comprising:
-
a plurality of luminous portions; and a control portion which controls turning-on of the plurality of luminous portions, wherein the control portion controls at least one of a luminous intensity and a color temperature of each of the plurality of luminous portions to regulate an amount of light in a wavelength range inhibiting melatonin secretion which is emitted in a predetermined direction. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
