Abstract

PURPOSE:To deliver signal in a desired range of time before and after the sunset and sunrise that change in accordance with season by measuring time of a set time with reference to sunrise and sunset by means of the output signal of a photo-electric conversion element and delivering timer output. CONSTITUTION:When light 1 from the surrounding is incident to a photo-electric conversion element E for a specified time after sunrise, a delay circuit D outputs signal to a first after-sunset timer T1 and a second after-sunset timer T2 to start time measurement by the timers T1 and T2, and output signal is delivered from the terminal O1 of a matrix circuit MX during the time measurement by the timer T1, and output signal is delivered from the terminal O2 from before the sunrise to sunset of the next day after the set time of the T2 has elapsed. At the time of sunset, first and second after-sunset timers T2 and T4 start time measurement in the same way. And signal is output from the terminal O3 from sunset during the time measurement by the timer T3, and from the terminal O4 signal is output from before sunrise to sunset in the next day.
