Abstract

A solar-powered light assembly is sealed and has a battery integral therewith, thus does not require servicing and is not prone to vandalism. The light assembly comprises at least one light-emitting diode (LED) powered by a rechargeable battery integral with the assembly. A solar panel on the assembly recharges the battery, and power management circuitry activates the LED at low ambient light intensities to prevent excessive changing of the battery and to prevent excessive discharge of the battery when it is low.
