  • High-Brightness LED Lamp With Battery Conservation
    Publication number: 20100327782
    Abstract: A high-brightness LED lamp with battery conservation and solar charging features. The portable, self-contained lamp utilizes one or more high-brightness LEDs to provide area or decorative illumination. A solar cell charging device maintains the rechargeable batteries during the daytime with available ambient light. An electronic control circuit conserves battery power by limiting the period of time that the LEDs are energized during nighttime hours when ambient lighting conditions cannot support the recharging function. A photodetector device allows the control circuit to make this determination.
