Rapid development in technology today, LED technology has begun to rise in the audiovisual field, this new light source has many benefits and advantages, will become the projection light source is also the main force.
With LED technology continues to apply and improve, not only in the industry launched a massive visual revolution, but in the end market boom triggered a sustained attention. LED technology with its Environmental protection , Energy saving, long life and many other advantages, quick access to public view, fully capture the public visual window. Including LED TV , LED Projector , LED LCD, LED Electronic Books, etc., all kinds of LED products, a very strong development momentum.
LED semiconductor light-emitting principle is to use the combination of electrons and holes sent photon, unlike the light bulb in the high temperature of 3,000 degrees or more operations need not be used as the fluorescent excitation of high-voltage electron beam, LED, and general electronic components the same, only 2 to 4 volts (V) voltage, at room temperature can be normal operation, so the life is more longer than traditional light sources, up to 100,000 hours or more (up to the present industrialization abroad 3 ~ 50,000 hours).
Luminous efficiency of incandescent 8-15 lm / W or so, ordinary T-8 fluorescent lighting efficiency halogen up to 40lm / W, T-5 high efficiency fluorescent lamps can reach 80lm / W, LED luminous efficiency can reach 200lm / w , LED also millisecond off time, which is the general application of light can not be achieved.
LED colors issued, mainly depends on the combination of electrons and holes release energy level, which is used by the band gap semiconductor material is determined. The wavelength of the same material are the same, so each one LED light colors are pure, mixed with traditional light sources are compared to a variety of colors, LED can be a digital source.
LED chip size can be cut arbitrarily for purposes, commonly used size 0.3 ~ 1mm or so, with the traditional light bulb or fluorescent light compared to a much smaller volume. For ease of use, LED normally use resin packaging, made of 5mm or so of various shapes, very strong seismic.
LED projection industry many advantages to have their blessing, the people familiar with the DLP big screen splicing, the loss marked a big disadvantage, let LCD splicing pressing harder and harder, Domination of the crisis the industry's position, but the LED light source in DLP industrial applications, for DLP big screen to take the initiative to re-splicing, the big screen in the future in industry, already have the ability to fight LCD splicing chamber.
With the Earth's environment deteriorated, the survival of the human damage caused by the growing, more and more attention to environmental problems that people, energy saving, environmental protection, these advantages not only affect the projection industry, also affect all of humanity future. It can be said, LED light source applications is not only an innovation in projection technology, it is more suitable for a technology the future of mankind.
