Basic characteristics of industrial display (LED) light sources

1, high luminous efficiency

After decades of technological improvement, LED's luminous efficiency has been greatly improved. Incandescent lamps, halogen tungsten lamps have a luminous efficiency of 12-24 lumens/watt, fluorescent lamps 50-70 lumens/watt, and sodium lamps 90-140 lumens/watt. Most of the power consumption becomes heat loss. The improved LED light efficiency will reach 50-200 lumens/watt, and its light has good monochromaticity and narrow spectrum. It can directly emit colored visible light without filtering. At present, all countries in the world have stepped up research on LED light efficiency, and their luminous efficiency will be greatly improved in the near future.

2, low power consumption

LED single tube power 0.03 ~ 0.06 watts, using DC drive, single tube drive voltage 1.5 ~ 3.5 volts, current 15 ~ 18 mA, fast response, high frequency operation. In the same lighting effect, the power consumption is one-eighth of that of an incandescent light bulb. One-half of the fluorescent tube, Japan estimates that if the LED is twice as high as the fluorescent lamp, it replaces half of the Japanese incandescent lamp. Fluorescent light. It can save equivalent to 6 billion liters of crude oil per year. As for the bridge guardrail lamp, the same effect of a fluorescent lamp is more than 40 watts, and the power of each LED is only 8 watts, and can be changed in color.

3, long service life

The use of electronic light field radiation, the filament is easy to burn, thermal deposition, light attenuation and other shortcomings. The LED lamp is light in weight and light in epoxy resin package, and can withstand high-strength mechanical shock and vibration, and is not easily broken. The average life expectancy is 100,000 hours. The service life of LED lamps can reach 5 to 10 years, which can greatly reduce the maintenance cost of lamps and avoid the pain of frequent lamp replacement.

4, strong security and reliability

Low calorific value, no heat radiation, cold light source, can be safely resisted: it can precisely control the light type and illumination angle, soft light color, no glare; no mercury, sodium and other substances that may be harmful to health. The built-in micro-processing system can control the intensity of illumination and adjust the way of illumination to achieve a combination of light and art.

5, is conducive to environmental protection

LED is an all-solid illuminant, which is resistant to shock and impact, and can be recycled without waste. The light source is small in size and can be combined at will. It is easy to develop into a light, thin and short lighting product, and is also easy to install and maintain. Of course, energy saving is the most important reason for us to consider the use of LED light sources. Maybe LED light sources are more expensive than traditional light sources, but we can recover the investment of light sources with energy saving for one year, so we can get several times of energy saving net income every year for 4 to 9 years. .
