Residential designers and builders agree that lighting is one of the most important elements in how homeowners feel in their space. Lighting technology has been evolving since the invention of the incandescent light bulb. With an eye toward sustainability and budget-friendly products, CFL (compact fluorescent lightbulbs) and then LED (light emitting diode) technologies took the lead in lighting for the home. And now there is a new player on the scene: OLED – Organic Light Emitting Diode.
LED lighting is still very popular and used in many lighting fixtures. Benefits of LED lighting include:
- Longevity – a longer lifespan than other bulbs so budget friendly, too
- Safety – cool to the touch and harder to break
- Environmentally friendly – using less energy than standard incandescent bulbs and easier to recycle, without the toxin mercury of CFLs
The colors offered by LED lighting are impressive, too. In lighting terminology this is called “temperature” and can range from warm to cool. Think of yellows and reds for warmth versus bright white and undertones of blue for cool. While incandescent bulbs are fairly limited in their temperature range, LEDs can cover the spectrum.
LEDs became popular in task lighting, especially under cabinet strip lighting for its brightness and clarity. OLED may well surpass LED lighting because it takes even less power to make brighter light, making it budget and environmentally friendly as well. It is thin and flexible so it can be used in many applications.
OLEDs are a diffuse-area light source produced in extremely thin sheets. A carbon-based semiconductor layer emits light when electricity is applied by adjacent electrodes. Electric current drives the light’s intensity. Color is determined by the emissive material used (e.g., red, green and blue emitters for white).
OLED technology is used currently in televisions, computers, smart phones and tablets. And now wonderfully innovative lighting fixtures in fabulous shapes are using OLED tech. We’ll be seeing more and more of this in the future.
Now that we’ve got you all excited about OLED, we have a bit of bad news. Currently, OLEDs are very expensive compared to LEDs. Plus, they don’t currently last as long as regular LEDs. However, as LED became the industry standard, the price for LEDs came down while efficiency increased – the same will hold true for OLED.
Stay tuned as we will have more to say about this emerging technology. There has never been a more exciting time to be in the home renovation business!
