Christmas Day is coming, we see that many holiday tree is decorated entirely with LED lights instead of the old-fashioned incandescent lights, and about half of the city's other light displays have been converted, too. More over, with less electricity needed, many people are seizing the opportunity to indulge their holiday spirit in bigger LED displays.
The technology of LED, or light emitting diodes, has grown in popularity because it uses about 10% of the energy consumed by incandescent bulbs. Rather than heating a filament inside each bulb, LED lights use a chemical compound that requires much less electricity.
The newer lights also are more durable, lasting as much as 100,000 hours, compared with traditional bulbs that often burn out after just 1,000 hours.
I think most people of the world watched the broadcast of the opening ceremonies from the 2008 Olympic Games in Beijing, yeah? What a sight it was! Five thousand years of Chinese history flowed on a huge LED scroll that unrolled to chapters of China's 5,000-year civilization.
The old incandescent bulbs required so much power that the holiday display often blew out fuses. Along with such practical concerns, LED lights are helping the environment by conserving energy.
