LEDsare seen as a potential solution for energy savings. If researchers arelooking to develop more efficient LEDs, then on the other hand,designers are preparing designs for LED lighting systems. An example ofthis blending can be given to “Light Spot” designed by German designerFelix Stark.
Thesystem is a sort of sticker that is totally made up of a foil composedof solar cells. It charges itself in the daytime when its button cellsare exposed to sunlight and at night it provides light using energyharnessed from sun. These units can be installed as flashlights toindicate exit or escape routes and fire exits etc.
