New Design's Adaptability (image) The Optical Society Caption This is an example of the new design's adaptability: If an LED street lamp projected its light from the center of the street, the light pattern on the road would be a rectangle. If the lamp stands on the side of road, it projects its light at an angle, producing a trapezoidal light pattern. The new design includes alternative configurations that would maintain the light beam's rectangular shape for a lamp that must project its beam at an angle, ensuring an even illumination of the road.
