Environmental protection and safety LED luminous word industry development direction analysis

Click:1244 Time:2018-03-05 12:54:01

LED luminous word lighting in line with energy-saving emission reduction, environmental protection, safety, is the future development direction of LED luminous characters. Currently, LED light sources mostly use LED light sources, especially in developed cities, and it is believed that future applications will be more extensive. The following is the LED luminous characters in the development of LED light direction:

  First, high luminous efficiency

  After several decades of technical improvements, LED luminous characters have greatly improved luminous efficiency. Incandescent lamps and tungsten halogen lamps have a luminous efficiency of 12-24 lm/W, fluorescent lamps 50-70 lm/W, and sodium lamps 90-140 lm/W. Most of the power consumption becomes heat loss. LED light efficiency will be improved to reach 50 ~ 200 lumens / watt, and its light is a good monochromatic, narrow spectrum, without filtering can be issued directly colored visible light. At present, all countries in the world have stepped up efforts to increase the research on LED light efficiency, and their luminous efficiency will be greatly improved in the near future.

  Second, less power consumption

  LED luminous word single tube power 0.03 ~ 0.06 watts, using DC drive, single-tube drive voltage of 1.5 ~ 3.5 volts, current 15 ~ 18 mA, the reaction speed, can operate at high frequency. In the case of the same lighting effect, the power consumption is one-eighth that of incandescent light bulbs, and one-half of fluorescent tubes, Japan estimates, such as the adoption of light-efficient LEDs that are twice as high as those of fluorescent light bulbs instead of half of Japanese incandescent lamps and Fluorescent light. Each year can save the equivalent of 6 billion liters of crude oil. In the case of bridge parapet lights, the same effect of a fluorescent lamp is more than 40 watts, while the use of LED's power is only 8 watts each, and it can change colorfully.

  Third, long life

  LED luminous characters using electronic light field radiation, filament light easy to burn, heat deposition, light attenuation and other shortcomings. The use of LED lights small size, light weight, epoxy resin package, can withstand high-intensity mechanical shock and vibration, not broken. The average life expectancy reaches 100,000 hours. LED lamp life of up to 5 to 10 years, can greatly reduce the cost of maintenance lamps and lanterns, to avoid the frequent replacement of the pain.

  Fourth, safety and reliability

  LED luminous characters have low calorific value, no heat radiation, cold light source, and can be safely touched: can accurately control the light and light angle, soft light color, no glare; does not contain mercury, sodium and other substances that may endanger health. The built-in micro-processing system can control the luminous intensity, adjust the luminous mode, and realize the combination of light and art.

  Five, is conducive to environmental protection

  LED luminous characters for the all-solid-state light, seismic, impact resistance is not broken, waste recyclable, no pollution. Small light source, can be freely combined, easy to develop into light thin short lighting products, but also easy to install and maintain.

  LED luminous characters have now been called the fourth generation of light sources, high-power LED luminous characters in outdoor lighting compared with the traditional light source has many advantages.
