The term “going green” has come to mean many things to different people in different industries. From small lifestyle changes to radical alterations in how companies configure their manufacturing lines, going green is evident in every aspect of daily life. Green initiatives have global visibility, global impact and make good business sense.
At Lumex, going green means advancing technologies and solutions that reduce, minimize or attempt to reverse the potential negative impact of technology on the planet. Even as user interfaces continually become more detailed and sophisticated, there are ways to ensure that we all play a role as responsible citizens. The LEDs, LCDs, back lights and light pipes that Lumex makes contribute to going green in several ways:
- Once designed in, they may never have to be replaced in the lifetime of the equipment, reducing maintenance and waste
- LEDs use 50% less energy than a traditional lighting source like incandescent or fluorescents
- Higher efficiency/higher brightness LED and LCD solutions means you can get more for less
- Lower power consumption means fewer greenhouse gas emissions
- Lower power consumption means greater battery life on portable and disposable equipment
- They contain no toxic mercury
- The vast majority are lead free
The best example of the positive impact LED technology can have on the environment in the short and long term is LED lighting. A 13 watt LED lamp produces 450 to 650 lumens which is equivalent to a standard 40 watt incandescent bulb. A standard 40 W incandescent bulb has an expected lifespan of 1,000 hours while an LED can continue to operate with reduced efficiency for more than 50,000 hours, 50 times longer than the incandescent bulb.
According to the US Department of Energy, a single kilowatt-hour of electricity will generate 1.34 pounds (610 g) of CO2 emissions. Assuming the average light bulb is on for 10 hours a day, a single 40-watt incandescent bulb will generate 196 pounds (89 kg) of CO2 every year. The 13-watt LED equivalent will only be responsible for 63 pounds (29 kg) of CO2 over the same time span. A building’s carbon footprint from lighting can be reduced by 68% in a single year by exchanging all incandescent bulbs for new LEDs. Over a 5 year period, the total carbon emissions removed from the environment would be greater than 665 pounds (301 kg) per building. In a city the size of Chicago, that could mean a reduction of up to 766,080,000 pounds (347,488,042 kg) of CO2 in five years. That is close to removing 63,840 cars from the road.
