In Colorado, LED lights are becoming more and more popular. Many people choose them as a solution of housing lighting. For decades, these energy saving lighting fixtures have been used in a wide range of applications, from Christmas tree decoration to alarm clock displays. As the LED technology fast development in recent years, they are now able to be used as regular light bulbs for domestic use, a good replacement of incandescent or halogen lights. More and more Householders tent to use them in order to reduce their power consumption, environment protection as well.
LED technology, which means light emitting diode, developed in the 1920’s by Russian scientist Oleg Losev, and largely ignored for the next 30 years. American scientists began to report on technology in mid-1950 and 1960 LED lights are being refined for consumer electronics. This illumination method has been modified in the coming decades, had their biggest gain in recent years with the development of white LEDs, enabling the technology to be used in home lighting.
LED work by making a charge through the semiconductor material that has been impregnated with impurities. The color of the LED light can be controlled by the materials used as impurities in the semiconductor material. The most common LED colors are red, blue, white and yellow.
Beyond home use, LEDs have many applications, including exit signs, light rail and traffic light sensor, the sources of light vision, flashlights, and photo therapy for skin diseases. LED is so versatile in part because its light spectrum can be controlled more accurately than other types of light.
The main drawback of LED lighting compared to other light sources, it is hard to handle. While high directivity is generally not required for domestic use, it is often necessary for industrial or commercial applications such as laser technology. The advantages of LED technology far outweigh the disadvantages, especially when considering energy efficiency. For homeowners, the LED option is too good to ignore.
