Abstract

PROBLEM TO BE SOLVED: To reduce any possible occurrence of self on-and-off light function.
SOLUTION: This lighting device controls the light operation which detects brightness at the spot nearby the front side by using a brightness sensor 8 such as cds element designed and fitted at a certain wall side 1 facing oppositely to the counterpart side wall 7, controls to light on the light source 3 consisting of the chip-type LED during darkness in the surroundings and controls to light out the light source 3 during brightness. The light source 3 is fitted to face the irradiation direction right in front of the opposite side wall 7 in keeping the brightness sensor 8 and not receiving substantially the reflected light (the virtual dotted line in drawing 4) from the opposite wall 7 by using the lens 4 (the transparent light cover of almost flat face) fitted at the front side of the light source 3 in setting the irradiation direction substantially as non-frontal direction.
