Energy-saving light bulbs might get greener
As many American consumers know, the ban on incandescent light bulbs is set to take effect in 2012. Leaders in the lighting industry have been preparing for this with some improvements to their energy-saving light bulb lines, and CFLs, LEDs and halogen bulbs are quickly becoming more of the norm in business and home lighting solutions.
LEDs are deemed the most energy-saving lighting supplies on the market, cutting back more than 80 percent in energy consumption. The bulbs can last for $50,000 hours, reducing the need for recycling as well as consumers’ replacement costs. Plus, a report from Osram says the manufacture of the bulbs has also been efficient – LED bulbs need less than 2 percent of their overall energy consumption for their manufacture.
It’s hard to believe these light bulbs could get any greener, but it looks like they soon will.
According to a report from MIT’s Technology Review, a new approach to making LED light bulbs will increase their energy-efficiency by 20 percent. At the same time, this new method of manufacture could result in higher-quality light than conventional LEDs produce.
The National Renewable Energy Laboratory in Golden, Colorado has demonstrated a new way for making LEDs that will make it easier – and more efficient – to produce white light through the technology.
By changing the light emitting diodes’ semiconductors to yield a yellow-green color light and a blue-green light, the diodes can be combined to make white light. This gives a color rendering index above 90 – which is a good thing, compared to the CRI of around 70 most energy-saving light bulbs achieve.
Moreover, this new process eliminates a lot of inefficiencies in the process of making LEDs. (Though, at 2 percent of overall energy consumption, some might say this was a pretty efficient process to start.)
With this in mind, consumers might more carefully investigate their LED home lighting options. The new LED technology could save a ton in electric bills and the cost of replacement bulbs while simultaneously helping to save our planet.Related Posts
