  • Patent number: 5013972
    Abstract: An eternal symbolic/religious memorial light having a flickering-candle appearance generated electronically by at least a pair of lamps and operated by a rechargeable battery charged/recharged by a solar cell unit, or by the solar cell unit itself. In an alternative embodiment, a light-dependent resistor (LDR) is incorporated to automatically adjust the current to the lamps in accordance with the background lighting conditions. Thus, the flickering appearance is made brighter during daylight when this is required in order to see the candle, and at nightfall, the brightness is diminished as the candle is more easily visible. In another alternative embodiment, the solar cells continuously run a user-programmed calendar/timer to turn on the lamp units only on specified memorial/anniversity days.
