Design challenges for solar-powered HB-LED lighting

摘要

Efficient power conversion is an important factor in typical HB-LED (high-brightness-light-emitting-diode) lighting applications-and especially in solar-powered applications. Designers of systems for these applications must not only maximize power from the solar panel but also condition it for maximum energy storage in the battery array and convert it for use in powering the HB LEDs (Figure 1).
