Abstract
This invention is a compact and portable solar-powered camping light/lamp that utilizes recent advances in bulb and battery technology to produce high-intensity light continuously for up to 12 hours. It is well-suited for use during camping trips, in remote off-grid cabins, homes, and emergencies. The device incorporates a 12V solar panel that charges a standard 12V 12-18 Ah Li-ion (LiFePO4) or Lead-acid battery. The 12V DC battery current is then converted by an inverter to produce 120V AC, which is fed to a standard 120V 15 W LED bulb, producing 1500 lumens of high-intensity light continuously for 9-12 hours. The device is equipped with a cooling fan, can be conveniently carried by its handle, and can be charged using an automobile or other 12V source and also at home with a 120V AC to 12V DC step-down adapter.
