  • Publication number: 20170310139
    Abstract: An integrated lighting system to efficiently manage battery life with indoor and outdoor modes by charging a battery during the day, turning on lights at peak night hours, and protecting the battery from overvoltage/leakage. The system comprises circuitry operable to connect to the battery and the LED light sources, the circuitry comprising a solar cell, a timer circuit, and a protection circuit. The solar cell charges the battery during daylight hours. The timer circuit regulates time periods during the day to turn on the LED light source. The overcharge circuit prevents damage from possible overcharge/leakage.

  • Patent number: 8201972
    Abstract: A decorative tree has a trunk, a plurality of double limbs and individual limbs connected to the trunk, and controlling electronics. Each double limb includes two individual limbs joined at a branch joint. Each individual limb has a plurality of flexible lamp stems and a molded branch formed around a structural rod. The lamp stem has two insulated wires, has a stiffening rod wrapped in a smooth sheath, and terminates in a molded lamp holder that supports an LED. Each lateral lamp stem connects to the molded branch at a molded branch fork and the tip lamp stem connects to an end of the stiffening rod. The controlling electronics provide an operating signal to the LED, which preferably causes the LED to sequentially emit more than one color in a repeated sequence.
