  • Patent number: 4568868
    Abstract: An improved controller for an automatic seasonal adjusting solar powered light having a rechargeable battery, a solar array for charging the battery, and a lamp. A detector is connected to the solar array for activating a first timer, upon sunrise of a given day, to count down for approximately twenty-two hours and then, after countdown, for activating a second timer for turning the light on for approximately a two hour period just prior to the rising of the sun on the next given day. A third timer is activated upon the setting of the sun on the next given day to turn the lamp on for approximately four hours. The light is turned on only for a predetermined total amount of time during each given day even though the individual dawn and dusk times for the light being turned on can be selectively adjusted. A battery circuit is provided for deactivating the lamp activation circuit in the event of excessive drain on the battery or due to cloudy days.
