світлодіодне та світлодіодне неонове світло. У чому різниця?
Why say LED Lantern Festival can? What’s the difference between it and neon? What’s wrong with LED lights?
Neon lights and ordinary energy-saving lamps are gaseous discharge luminescence principle. Neon lights are produced by the use of high pressure ionized gas at cold poles, and they give out different colors because of the gas filled in the tube. Ordinary energy-saving lamp is by the filament heating electrons free impact mercury atoms emit ULTRAVIOLET light and then stimulate the phosphor to transform color, emit visible light.
Using different phosphors produces different colors. Therefore, neon lights and ordinary energy-saving lamps are linear tube, large volume, especially neon tubes will have transport problems.
In terms of luminous efficiency, each lamp has different luminous efficiency in different colors. Until now, the gap between the efficiency of LED white light and that of conventional CFLS was relatively small. But after that, LED white light will surpass ordinary energy-saving lamps and gradually widen the gap. The overall light efficiency of red LED light is higher than that of neon light, while the overall light efficiency of neon light is higher than that of green LED light. LED lights in the market of commercial signs can only be dominant in a small space environment, larger sign advertising, neon lights as a whole cost-effective.
The main shortcomings of LED lamps are light decay and heat dissipation problems, but these problems are constantly improving. The combination ability of LED lamp and digital technology and the mechanism of variable color are absolute advantages; In the future, production costs will continue to decrease, and LED power will come to the fore in the market competition.
The pros and cons of LED versus neon
Neon light is a very wide range of outdoor advertising forms.(1) Rich color, червоний, orange, yellow, зелений, зелений, блакитний, purple and other colors.
(2) High brightness, suitable for high-rise buildings.
(2) Built-in chip control, rich in dynamic, can achieve a variety of color, pattern change
(3) Moderate cost.(1) Because the neon light should be attached to the metal characters or metal plate surface, exposed to it, the line is also exposed, so the effect is poor during the day, not suitable for low-rise buildings or well-decorated facade.
(2) Neon lights use high voltage, high power consumption, according to one square meter of word work 8 години, the annual electricity consumption, in the power limit city, the use of neon lights approval and use process are very high restrictions.
(3) In low-rise buildings, the brightness is high, dazzling, and light pollution is serious.
(4) Neon lights do not have any protective ability, it is easy to be broken, incomplete, air leakage.
In addition to the advantages of no mercury, energy saving, material saving, no electromagnetic interference to the environment, no harmful rays and so on, LED light source has many outstanding advantages in the field of lighting, especially in landscape lighting. Such as:
(1) Low voltage power supply: no high voltage link, the cost of insulation is much smaller, high reliability; Also to one square meter of word work 8 години, the annual electricity consumption is only degrees.
(2) Simple accessories: no starter, ballast or ultra-high voltage transformer;
(3) Simple structure: has the biggest advantage of solid light source, no inflation, no glass shell, no gas sealing problem, impact resistance;
(4) Pure thick color: produced by the semiconductor PN junction itself color, pure, thick, soft and not dazzling;
(5) Rich color: three primary colors and digital technology, can evolve any color;
(6) Small size: large LED lamps can be regarded as composed of LED cells, the smallest LED is only square millimeter,
Order of magnitude to adapt to point, line, surface, ball, heteroform and any artistic modeling lighting sculpture lighting requirements;
(7) No maintenance: 100,000 hours of life, can be used for 50 років, greatly reducing the maintenance cost during the use;
(8) Can achieve jump, gradual change, synchronization and other color changes, through the program control to achieve text, pattern display. At present, the cost of LEDS is relatively high (2-3 times as much as neon lights). Проте, considering the cost of electricity and maintenance during use, using LED light sources is more suitable than neon lights. For detailed data comparison, please refer to our other article: LED light sources versus Neon lights.
Conclusion three:
Due to the high brightness led brightness rise and fall of prices, coupled with the long life, energy saving, simple drive and control and the neon lights, from the current use of super high brightness leds made monochrome, multicolor and even the color of light and other shape of lighting units to decorate the tall buildings, Bridges, landscape engineering, led used for landscape lighting is a trend.
