Device for optimized use of light from gas lamps places a hollow body over a gas lamp to blank out undesirable rays of light and to generate a current with the help of a built-in photovoltaic

摘要

An adjustable opening allows a portion of light that escapes to be defined according to one's own estimation. A photo-current remaining in a hollow body like a folding box falls on photovoltaic modules that use captured light to generate current. Designed as a collapsible carrier for solar modules, the hollow body permits very flexible use. It is easy to fold up and carry away.
