In the use of electric energy, lighting power accounts for a considerable proportion. The fluorescent lamps and energy-saving lamps that we use nowadays have greatly improved the luminous efficiency compared with the earlier ordinary incandescent lamps, and have obtained a wide range of application. As the level of manufacturing technology continues to increase, LEDs (light-emitting diodes) are also widely used in various lighting fields.
LEDs have higher luminous efficiency, lower power consumption and longer service life, and have achieved very good results in urban lighting projects and home lighting. In the current energy shortage environment, LED energy-saving technology will become a very important development direction. Our country has launched the “Semiconductor Lighting†project to develop and promote it as a new generation of green lighting sources.
First, the advantages of LED lighting
1. High luminous efficiency
After decades of technological improvements, LEDs have greatly improved their luminous efficiency. The incandescent lamp and halogen tungsten have a luminous efficiency of 12~24 lumens/watt, a fluorescent lamp of 50~70 lumens/watt, and a sodium lamp of 90~140 lumens/watt. Most of the power consumption becomes heat loss. After the LED light effect is improved, it 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 are doing research on improving LED light efficiency, and their luminous efficiency will be greatly improved in the near future when they assemble LED lighting.
2. Low power consumption
The LED is driven by DC. The single-tube driving voltage is 1.5~3.5V, the current is 10~18mA, the reaction speed is fast, and it can work at higher frequency.
In the case of the same lighting effect, the power consumption is about one tenth of that of an incandescent bulb, which is about one third of a fluorescent tube. Take the bridge guardrail lamp as an example. The same effect of a fluorescent lamp with ballast loss consumes more than 40 watts of power, and the power of each LED is only 10~15W, no ballast is needed, and it can change colorfully.
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 small in size, light in weight and epoxy resin package, and can withstand high-strength mechanical shock and vibration, and is not easily broken. LEDs have an average life of 100,000 hours. The ordinary white LED used for illumination has an effective service life of more than 20,000 hours, and the special illumination LED known as zero light decay has a longer life. The service life of LED lamps can reach 5~10 years, which can greatly reduce the maintenance cost of lamps and avoid the pain of frequent lamp replacement.
4. Strong safety and reliability
Low calorific value, no heat radiation, cold light source, can control light type and illuminating angle, soft light color, no glare; no mercury, sodium and other substances that may be harmful to health.
5. Conducive to environmental protection
The 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 source with energy saving for one year, so we can get several times of energy saving net income every year for 4~9 years. .
