Thin-film light sources have been around for awhile, despite how futuristic they seem to be. Their adoption has been relatively slow for two reasons: First, they have fairly limited light ouput, which restricts them to mostly decorative applications. Second, they are more difficult to implement in architectural designs, usually requiring a lot of custom design. Not that that are difficult to use…they are just not as simple-minded and quick as copying yet another downlight symbol on a reflected ceiling plan. Lifetime varies, depending on how bright they are driven, which is another consideration.
Yet still, the opportunity for creative new explorations of lighting is obvious, such as our previous post on a concept for light emitting wallpaper.
