The plasma source and the LED racing together bridle to bridle into competition

With the development of science and technology, foreign scientists after try, developed a new type of lighting source plasma lamp. Plasma lamp is the rise in the energy sector in recent years is a new electromagnetic wave excitation, non luminous matter electrode glass lamp inside the ball, so that the light emitting material for visible spectrum, and issued only trace UV and IR, is a kind of high efficient lighting system. In the 2010 stage of the performing arts equipment technology and stage art development forum, Professor Peng Miaoyan, director of the Institute of audio and video technology, Guangzhou University, Professor, the current LED lamp and plasma lamp has become a competitive relationship. LED lighting era known as the fourth generation of light emitting diode (LED) is currently the fastest growing, is considered to be the new light source has broad prospects. LED has many advantages: (1), long life, up to 100 thousand hours. Incandescent lamp is only 1000 hours or less (2), low power consumption, energy saving. (the above is the two most important advantages of LED) (3), solid structure. (4) short start time. (5) the illuminant is close to the electric light source, and the size is small. (6), can be made of thin lamps. LED currently used in the field of lighting is extensive, including the application of LED lighting technology mature signal lighting, landscape lighting and local lighting (such as lamps) and large screen video display etc.. And gradually into the field of stage lighting. LED developed rapidly, but there is also a need to overcome disadvantages: (1), a lack of brightness; (2), the price is too high; (3), single species: single plane arrangement mode, beam is not adjustable (spot not adjustable); (4), sensitive to temperature: the heat problem is difficulty. Then LED to enter the field of general lighting, need to solve the following problems: (1), sufficient luminous flux, kilolumen above; (2), close to the white color; (3), the color is better; (4), the right price; (5), as the art of lighting or signal lighting, direct viewing light emitted by the LED itself; and as a general lighting, is to watch the indirect objects illuminated by LED. Above, especially the 1,4,5 three, is still the weakness of LED, to be further solved.

The new light source plasma source LED competitor and new light source plasma light source, is now becoming a rival to the LED. The plasma lamp with its high luminous efficiency, long life, high color and is considered to be a promising fourth generation light source and LED competition. According to the information: LED current advantage is more suitable for low and medium intensity applications; plasma lamp is the highlight of the advantages of high intensity lighting field. Plasma lamps a lot of advantages. (1), LIFI lamp can achieve the luminous efficiency in the range of 60LM/W to 120LM/W. (2) the (LIFI) color rendering index (CRI) increased from 80 in recent years. (3), LIFI lamp color temperature is in the range of 6500K to 10000K. (4), LIFI lamp life of up to ten thousand hours or even longer, which means that every day to ignite the conditions of the next 8 hours, can work for 3 years and zero months. (5), LIFI lamps are particularly suitable for commercial lighting, street lighting, architectural lighting and entertainment lighting. One of the advantages of LIFI 1, you can quickly start LIFI, is a very high speed start function and LED. For ultra high pressure mercury lamps, it takes about 30 seconds to turn off the light, so it will give people a slower start to the product. The LIFI startup time takes only 1~2 seconds, almost the same as LED. 2, long service life. Mercury lamp system using time for thousands of hours, LIFI and LED have the same long life, exchange basically does not need lamps. In theory, the life span is 25000 hours, and the brightness of the screen is reduced by 80%, which basically has the same service life as liquid crystal TV and ion television. As a product, users do not need to exchange. , 3 color gamut widely comparable to LED from the spectrum, red and green color has gone beyond the LED, although in the light green on less than the former, but also beyond the mercury line. According to the performance of color gamut seen in TOTAL, reached 144% of sRGB, it is surprising. Has these advantages, after all is still in its action principle. LIFI still uses the shape of a spherical bulb, so it can't be changed to mercury. Inside the bulb into the compound and gas and metal halide, first to produce electric field inside, so that the internal gas ionization and ion, manufacturing. And then the gasification of the ionized gas and halogen. Let the two merge with each other to produce white light. According to the data: the advantage of LED is currently application, suitable for low illuminance. The advantage of plasma lamp is to focus on the field of high intensity lighting. The plasma lamp with its high luminous efficiency, long life, high color and is considered to be a promising fourth generation light source and LED competition.
