LED lighting, as mentioned many times before, has always been a part of our daily lives over the years, it was mainly due to the signal light electrical form or in a calculator or watch digital display. However, the recent Flexible LED strip, has become the most popular market for energy-saving products to promote not only environmental, but also organizations and our government. This undoubtedly shows that for the LED solutions, select worthwhile investment, and encourage manufacturers to put more emphasis on areas of research and effort.
When it comes to household use of LED bulbs, the main problem is clearly a cheaper and more in the form of bright white light in the traditional filament light bulb as the light of a similar size. The size of the bulb is limited, and for light intensity requirements are very high, researchers need to work together on problems in several areas. A single, white LED light intensity challenges and work every day. February, the United States to create a CREE LED can emit 208 lumens from a watt.
LED is a form of solid state lighting (SSL) and multi-photon production of casing be trapped. The way researchers try to create a more intensive one white LED in the tube by increasing the number of microscopic holes, so that photons. Some researchers in the University of Glasgow research team is looking for a cheaper production of such LED lights the way successful.
Another researcher at Cambridge University in England, but the increasing use of LED manufacturing GaN semiconductor materials, silicon base is also a cheaper way fixed light intensity. These lights will appear on the market by 2012.
Increase the intensity of the LED may have been available, a light bulb placed in the limited space that they are a difficulty. LEDs are very sensitive to heat, but lost its life and light intensity, as this is very easy. High-power light emitting diode to generate more heat than other technologies LED (because they emit more light too), so the bulb’s heat management is a key issue. LED lighting technology is another development direction of the growing intensity of the LED lamp designed thermal management problems.
Since entering the study, so the work in the field of LED lighting, increased product quality, the major development expected. LED in the near future will replace the light bulb or even more strength and life of incandescent 100W, up to 1 million hours long.
