Lighting circuit control apparatus
First Claim
1. A light circuit control apparatus for turning on and turning off a plurality of lighting circuits in a first and a second predetermined sequence, respectively, comprising:
- control means responsive to the intensity of ambient light in an area illuminated by said lighting circuits for turning on a succeeding one of said lighting circuits in said first predetermined sequence each time the intensity of the light in said area decreases to a first predetermined intensity and for turning off a succeeding one of said lighting circuits in said second predetermined sequence each time the intensity of the light in said area increases to a second predetermined intensity.

Abstract
A light circuit control apparatus for controlling the illumination of a predetermined area is described comprising a photocell coupled to a first comparator circuit for generating a "light-on" signal when the ambient light in the predetermined area decreases to a first predetermined intensity and a second comparator for generating a "light-off" signal when the ambient light in the predetermined area increases to a predetermined intensity, and logic circuits including flip-flops for turning on and turning off a plurality of lighting circuits in a predetermined sequence in response to the "light-on" and "light-off" signals generated by the comparator.
