Research shows: switch to LED lighting can save $1 trillion and 800 billion

According to the Rensselaer Polytechnic Institute (RenssELaer Polytechnic, Institute, RPI) of LED lighting in the next ten years is expected to $1 trillion and 800 billion (trillion) of electricity, and coal-fired power plants to reduce the burning of 1 billion barrels of crude oil, and thus eliminate two of carbon dioxide emissions 10 billion tons.

Designed to replace the existing incandescent lamp (incandescent) and fluorescent lamp (fluorescent) LED solid-state lighting, has always been regarded as a significant power saving, environmental protection and less pollution of a new generation of lighting technology. RPI's wisdom lighting engineering resource center (Smart Lighting Engineering Resource Center Jong Kyu Kim) professor said, as long as the LED in the next ten years to replace the traditional lamp can reach 80%, the huge energy saving effect.

Kim also pointed out that, LED lighting can not only replace the traditional light bulb, but also is expected to control its spectrum (spectrum), space emission pattern (spectrum), light polarization (polarization) and temporary modulation (temporalmodulation), etc..

RPI intelligent lighting engineering resource center made by the National Science Foundation (NSF) recently offered a $185 million sponsorship, and Boston University (Boston University) and the University of New Mexico (University o fNewMexico) R & D cooperation in five years of innovative optical materials, new technology and new elements of smart lighting applications.

Kim pointed out that the traditional lighting technology for LED, like transistors in vacuum tube, transistor start simply vacuum tube become a substitute, but derived from the integrated circuit (IC) revolution; and LED is the same, the beginning is only the traditional light bulb replacement, lighting systems with different functions the future will be derived, integrated, like effect brought about by the IC transistor technology.

If only is simple to replace the traditional light bulb, energy saving efficiency of LED is 5 times, 20 times of incandescent bulbs with fluorescent lamps; and the current research of RPI is to develop applications for LED updates, including three main directions: first, according to the application of medical control LED spectrum technology; the second is Study on the control of the temporary variable, in order to realize the wireless optical network; the third is to control the LED light polarization, to enhance display technology.

In the part of the spectrum control, RPI says, it is possible to develop lighting that can change the color of the light during the day, to positively affect the mood of the workers, or to treat some of the medical problems caused by poor light. To the modulation technique for LED'm afraid I need some time to see, this technology can make the lighting equipment can also do for wireless internet access, direct links from different equipment data flow, do not like the RF wireless technology today that need all the devices share the same frequency band.

As far as controlling the polarization of the LED light, the LCD display can be exempted from the need of the filter, and the brightness of the display can be greatly increased while the power consumption is saved. Other smart lighting applications developed by RPI, including rapid cell identification, interactive roads, accelerate plant growth, and reduce the risk of certain cancers and other projects.
