LED lighting has taken huge strides over the past few years. Which leads us the question. What is the future for LED lamps now? Well, it seems Organic LEDs are now going to be the future of the lighting industry.
They are already being used in televisions due to their small size, but will this technology soon be available as an alternative to the LED lamps we know today? Thanks to an organic conductor, organic LEDs have the potential to be incorporated into lighting displays, furniture, buildings and eventually into more mainstream light sources such as modular panels and standard household lamps.
The incandescent lightbulb, synonymous with the inventions of Thomas Edison, has, until recently, been ever present since the late 19th century. In recent years such lightbulbs have been replaced gradually with the new energy saving technologies of LEDs. However, just as semiconductor LEDs are becoming mainstream, owing to them now being able to produce warm white light having a spectrum similar to the incandescent bulb, a new type of LED may take their place. Organic LEDs (OLEDs) contain a luminescent layer that is a film of an organic semiconductor compound that emits light in response to a current being passed through. As OLEDs can be manufactured with transparent electrodes, a whole panel can be manufactured that may then be illuminated to provide light over a large area. This contrasts with conventional lightbulbs whose light is emitted from a single location.
