OLEDs, or Organic Light Emitting Diodes, are made from flexible organic materials that can be placed in almost anything. However, this technology is still in the early stages of development. Currently OLEDs are more prevalent in technological applications, such as flexible screens and TVs, but goes comes without question the future is bright for this technology.
For obvious reasons, natural daylight is the greenest way to illuminate any space. For most people this can be achieved through strategically placed windows and skylights, but not every space has the same direct access to the sun. Fortunately, there are several different technologies that do not require direct sunlight to function, but still remove electricity from the picture. Light transmitting systems place a light gathering receptacle on your roof which uses fiber optics to redirect the natural sunlight into your home or other spaces.
Increased natural daylight can also be achieved with mirrored devices (also known as heliostats) that redirect the sun’s rays from your lawn or garden into your home. A single heliostat directed through a window or skylight can deliver the equivalent of 40 100-watt incandescent bulbs. Both of these options are a great way to add light to any dark room, but as you can imagine, neither option works after the sun goes down.
