Abstract: An improved solar powered LED-based lighting fixture providing substantial increases in the apparent light output compared to prior art solar powered LED-based lighting fixtures. This improvement in preferred embodiments results from the addition of inexpensive spherical lenses that create a large number of images of LED light sources, each image having substantially reduced brightness as compared to the real LED light source. These images with substantially reduced brightness result in beautiful patterns, that still appear very bright to a night time observer, because the LED source itself is in fact too bright to look at directly. In a preferred embodiment ten plastic 0.5-inch spherical lenses are positioned along the bottom edge of the cone at the bottom of lamp. Each of these spherical lenses creates multiple images of the single source LED, all nearly as bright as the source itself. As a result the perceived delivery of light intensity to an observer is multiplied by a factor of approximately 10 times.
