Light pollution is extremely difficult to avoid, but the LED Street Lamp concept takes a stab at it with a flat illuminating plane and edging that directs the beam downward. A number of features make this urban lighting concept a significant improvement upon the majority of existing systems.
Felix Runde's streetlight is high-efficiency and low-energy illumination that brightens the road below and not the entire neighborhood around it. It's characterized by elongated O-shaped lightbulbs attached to adjustable braces that allow the fixtures to be raised or lowered in optimization for the activity happening underneath.
Another great aspect of the LED Street Lamp proposal is the ease with which it can be maintained. Its convertibility makes it easier to repair and change a dimmed source.
