Solar 'Day Lamp' Also Powers FM Receiver

摘要

A SOLAR-POWERED. DAYTIME-ONLY LAMP without a battery for energy storage may seem to be a marginally useful device, but many areas in homes and offices are relatively dark, even during the daytime. This "day lamp" provides light throughout the day from a nearby solar panel, and supplies regulated auxiliary power of 0.5 W for a small load (such as an FM receiver) at very small incremental cost.
