With the emergence of high brightness white LED light source, it is possible to apply it in the lighting field. According to the prediction of international authoritative organizations, the 21st century will enter the era of new light sources represented by LED, that is, the fourth generation of new light sources. At present, lighting power consumption accounts for about 20% of the total power consumption, and greatly reducing lighting power consumption is an important way to save energy. In order to achieve this goal, the industry has developed a variety of energy-saving lighting appliances, and has achieved certain results. However, the requirements for "green lighting" are far from enough, and new light sources that are more efficient, reliable, safe and durable need to be developed and applied.

LED has attracted the attention of the world with its inherent advantages. According to the prediction of the United States Department of Energy, 55% of incandescent and fluorescent lamps in the United States will be replaced by LEDs by about 2010. LEDs can save 35 billion dollars of electricity annually, resulting in 50 billion dollars of electricity bills. USD industry. Japan proposed that LED would replace traditional incandescent lamps on a large scale in 2006. The development history of LED has been decades, but its application in the field of lighting is still a new technology. However, with the rapid development of LED technology and the gradual improvement of luminous efficiency, the application market of LED will be broader, especially when the global energy shortage is once again worrying. Against the rising background, the prospect of LED in the lighting market has attracted more global attention. This industry is considered to be a promising investment market in the next decade, and a new type of light source that may replace the traditional light source.

The service life of LED lamps is more than 5 to 10 times that of ordinary lamps, almost maintenance free, and there is no frequent replacement of light sources and ballasts. The green and environment-friendly semiconductor light source has soft light and pure spectrum, which is conducive to protecting workers' eyesight and health.

As the fourth generation light source, semiconductor light-emitting diodes (LEDs) have many advantages:

(1) High light efficiency: the spectrum is almost all concentrated on the visible light frequency, and the efficiency can reach 80% - 90%. The visible light efficiency of incandescent lamps with similar luminous efficiency is only 10% - 20%.

(2) High light quality: because there is no ultraviolet and infrared ray in the spectrum, there is no heat and radiation. This is a typical green light source.

(3) Long life: the standard life is 40000 hours when the luminous flux decays to 70%. LED lights can be used for 8 years under normal conditions.

(6) Green environmental protection: waste can be recycled, without pollution, and does not contain mercury like high-pressure mercury lamp.

(7) Very short response time: energy-saving ceiling lamp suitable for frequent switching and high-frequency operation

2. Characteristic comparison between traditional mining lamp and LED mining lamp

Traditional mining lamp

1. The traditional mining lamp is not allowed to be started frequently. Because the filament of the bulb will be affected by the high voltage every time the bulb is started, the starting current is 2 to 3 times of the current during normal ignition. Starting speeds up the consumption of electronic emission materials on the filament, and when the filament is powered on, when the electronic emission materials of the lamp are exhausted, the life of the lamp tube will end.

2. Short service life: the service life of the mining lamp is about 3000 hours; The current popular mining lamp has a service life of only 5000 hours;

3. It contains a large amount of mercury vapor. If it is decomposed, the mercury vapor will volatilize into the atmosphere;

4. Traditional industrial and mining lamps will generate a lot of heat energy, which is not environmentally friendly. In addition, they can also lead to the aging of lamp legs and the falling of ceiling lamps.

5. Noise generation;

6. AC power is used, so 100-120 stroboscopic flashes will be generated per second, which will affect vision;

7. It produces ultraviolet rays and attracts many mosquitoes to surround the light source.

LED mining lamp

1. LED lamps are energy-saving, low power consumption and high luminous efficiency. LED lamps have high luminous efficiency. The power of a single LED lamp is 0.06 to 1 watt, which is driven by DC. The drive voltage of the single tube is 1.5 to 3.5 volts, and the current is 15 to 18 mA. Fast reaction speed and can be operated at high frequency. Under the same lighting effect, the power consumption is one eighth of that of incandescent bulbs and half of that of ordinary ceiling lamps.

2. LED lamps are environmentally friendly and light is healthy: the light source used by LED lamps does not contain mercury, lead and other harmful elements, which is conducive to recycling and does not produce electromagnetic interference. Ordinary lamps contain harmful elements such as mercury and lead, and the ballast in ordinary ceiling lamps will cause electromagnetic interference. The Ra value of the LED light/color body is close to 100, the color temperature is 5000K, and the color temperature close to the sun is 5500K. It is natural light, stable lighting, DC drive, stroboscopic free, energy-saving, and eye protection. The ordinary lamp is driven by alternating current, which will inevitably produce stroboscopic. LED lamps do not contain ultraviolet and infrared rays, nor do they generate radiation. Ordinary lamps contain ultraviolet and infrared rays.

3. LED lamp safety: LED lamp is driven by low voltage inside, with small current, stable light emission, less heat, cold light source and safe touch. It is a typical green light source.

4. Long life: LED lamp is called long-life lamp. Its light source is a solid cold light source, which is encapsulated in epoxy resin. There is no loose part in the lamp body, no filament luminescence, flammability, hot deposition and other shortcomings. Its service life can reach 50000 to 80000 hours, more than 10 times the service life of traditional light sources.

5. No noise: LED light will not produce noise, which is the choice of using accurate electronic instruments. It is suitable for libraries and offices.

6. Don't blink and protect your eyes: The traditional ceiling lamp uses AC power, so it will generate 100-120 stroboscopic flashes per second. LED lights directly convert AC power to DC power without blinking and protecting eyes. 6000K cold light source gives people a sense of visual coolness, which helps to concentrate and improve efficiency.

7. No mosquito trouble: LED lights do not produce ultraviolet light, so unlike traditional lights, there are many mosquitoes around the light source. The interior will become more clean and tidy.

8. Wide voltage regulation range: 90V-265V traditional ceiling lamp is lit by the high voltage released by the rectifier, but cannot be lit when the voltage drops. LED lights can be lit within a certain voltage range, and the brightness can be adjusted.

9. LED lamps are easy to install and have a wide range of matching. At present, LED lights have a traditional appearance and are very easy to install. They can be cut into every lighting space in daily life at any time. In addition, LED lights are highly energy-saving, so they can be used together with solar energy and wind energy, which greatly reduces the cost of outdoor and indoor lighting, and reduces the power load of the country.

In conclusion, we can draw the following conclusions:

1. Compared with traditional lamps, LED lighting has obvious energy-saving advantages. Although the initial investment in replacing traditional lamps with LED lamps has increased, cost recovery can be achieved by saving electricity bills in a relatively short time. The earlier you replace it, the more you can enjoy the benefits of energy conservation.

2. The energy-saving performance of LED lighting is the choice to replace the traditional mining lamp. In the context of global energy contraction and the national conditions of governments at all levels to vigorously promote energy conservation and environmental protection, replacing traditional lamps and lanterns will become a major trend of LED lighting, There is a lot to do.
