Abstract
An apparatus includes a light emitting diode for at least illuminating a pathway. A rechargeable storage device provides a discharge current to the light emitting diode. A solar panel supplies a charging current to the rechargeable storage device during exposure of scattered light of at most 900 foot-candles. The ratio of the charging current to the discharge current is greater than 0.5. A safety device protects the rechargeable storage device from substantial overcharging during exposure of direct sunlight. A recharging switch supplies the charging current to the rechargeable storage device during a charging mode. A discharging switch supplies the discharge current to the light emitting diode during an illumination mode. A low light sensor effects a switching between the charging mode and the illumination mode.
