| 摘要 |
<p>The autonomous solid state lighting system (100) of the present invention has a charge mode which collects energy and produces electric power with a solid state energy source (110), converts the voltage of the electric power using a bi-directional power converter (130), and stores the power in an energy storage device (140), and has a discharge mode which draws electric power from the energy storage device (140), converts the voltage of the electric power using the bi-directional power converter (130), and produces light from a solid state light source (120). A controller (150) controls the charge and discharge modes. In one embodiment, the solid state energy source (110) can be a solar cell panel, the solid state light source (120) can be an LED module, and the energy storage device (140) can be a battery pack.</p> |
