Abstract

A daylight sensor having: a plurality of photoelectric detectors arranged in a manner that a certain number of photoelectric detectors (A) among them is or are disposed so as not to be exposed to direct sunlight and remaining number of photoelectric detectors (B) among them is or are disposed so as to be able to detect direct sunlight when there is direct sunlight and, in which the daylight sensor detects the presence or absence of direct sunlight on the basis of a difference between signals obtained from the photoelectric detectors.
