Environmental protection and safety -- Analysis of the development trend of LED luminous character industry
Adddate:2017-09-09 09:33????Hits:

  LED luminous character lighting conforms to energy conservation, emission reduction, green environment protection and safety. It will be the development direction of LED luminous character in the future. At present, most of the LED luminous characters adopt LED light source, especially developed cities have been more popular, and I believe that the future application will be more extensive. The following is the development direction of LED luminous character in LED luminescence:

First, high luminous efficiency
After several decades of technical improvement, the luminous efficiency of LED luminous light has been greatly improved. Incandescent lamp, halogen tungsten lamp, light efficiency of 12-24 lumens / watt, fluorescent lamp 50~70 lumens / tile, sodium lamp 90~140 lumens / tile, most of the power consumption into heat loss. The LED light effect will be up to 50~200 lumens / watt after improvement, and its light color is good and the spectrum is narrow. Without filtering, it can directly emit colored visible light. At present, all countries in the world are stepping up efforts to improve the LED light efficiency research, and in the near future, the luminous efficiency will be greater.
Two, less power consumption
LED luminous word single tube power of 0.03 to 0.06 watts, using DC drive, single tube drive voltage 1.5 ~ 3.5 volts, current 15~18 Ma, fast response, can be operated at high frequency. The same lighting effect, power consumption is 1/8 of incandescent bulbs, fluorescent tubes, 1/2 Japanese estimates, such as the use of incandescent lamp and fluorescent lamp fluorescent lamp with high light efficiency more than two times the LED replace half of japan. It can save up to 6 billion litres of crude oil a year. Bridge guardrail lamp, a fluorescent lamp of the same effect more than 40 watts, and the use of LED power each only 8 watts, and color change.
Three, long service life
LED light emitting words are used to radiate light by electron light field, and the filament is light emitting, easy to burn, heat deposited, light attenuated and so on. The LED light, small size, light weight, epoxy resin package, can withstand high mechanical impact and vibration, not easy to break. The average life span is 100 thousand hours. The service life of LED lamps can be up to 5~10 years, which can greatly reduce the maintenance cost of lamps and lanterns, and avoid the frequent change of lamps.
Four 、 safe and reliable
LED light emitting words have low calorific value, no heat radiation, and cold light source can be safely touched: the light type and luminous angle can be precisely controlled, the light color is soft, without glare, and the substances that do not contain mercury and sodium elements can be harmful to health. The built-in micro processing system can control the luminous intensity, adjust the light emitting mode, and realize the combination of light and art.
Five, conducive to environmental protection
LED light for all solid body, shock resistance, impact resistance is not easy broken, waste Recyclable, no pollution. The light source is small in size and can be assembled at will, and is easy to develop into light, thin, short and small-sized lighting products, and is easy to install and maintain.
LED luminous word has now been called "fourth generation light source". High power LED light has many advantages compared with traditional light source in outdoor lighting.
