Lighting requirements for coal mine A good mine lighting, it should be under the condition of ensuring the safety of the, according to the requirements of ore production and livelihood of the workers, physiological health, technology, economic and reasonable and possible, lighting set-up for mines, safe and reliable, flexible and economic. In terms of quantity, the illumination level is suitable, which is easy to control and adjust to meet the needs of different places of production and the different time of the unified place. In terms of quality, the requirements of good uniformity of the lighting, brightness space distribution is reasonable, visual target and background (especially the brightness of the surface is appropriate, avoid glare, good color.
Coal mine lighting problems: at present some mine lighting is still in the primary stage, still using the first generation of lighting incandescent light source, the light emitting efficiency is low, high heating temperature, short life (average only 500h), infrared ingredient is high, vulnerable to vibration, low color temperature, with yellow, high energy consumption, is not conducive to energy conservation. This poor lighting environment is extremely detrimental to the production of workers:
(1) the underground light is too weak, the average illumination intensity is only 3.91x. Because the air quality is too poor, so that transparency is not good, the workers are not clear about the environment, the advent of the accident and the potential damage to turn a blind eye;
(2) the color selection of underground lighting is not properly. In the absence of natural light, pale yellow walls in incandescent dim light blurred, so that workers of potentially dangerous accident sources are observed not to, not by the naked eye of roof rock and the impending cave are identified, and then take effective measures to prevent and avoid; (3) underground lighting lamp power and the surrounding environment does not match, leading to falling rock and exposed rock roof or cracks criss cross the lack of careful observation and judgment;
(4) due to the underground environment visual difference, lack of accurate judgment for approximation of sports injury, visual distance difference, the static security trap without alert sense and awareness of prevention.
(5) underground space is very narrow, due to insufficient lighting, single headrest wears a miner's lamp, the beam only set shot in diameter less than 1m in circle, miner's lamp intense glare, affect each other, extremely unfavorable. (6) incandescent lighting efficiency is low, power consumption, short life, resulting in a huge waste of energy and money, the direct economic losses of up to several million per year. Therefore, in order to change the unfavorable situation, the high luminous efficiency, long service life, suitable for color, economy is durable and reliable source; requirements equipped with safe and convenient, effective and low price, reasonable light, good interchangeability and easy maintenance of LED lamps and lanterns.
Source: incandescent lamp is a kind of traditional light source, the average life expectancy of less than 500h, attenuation is very large, in the underground 24 hours uninterrupted lighting without a month, incandescent lamp luminous flux decays to less than half of the original, have a great impact on the lighting effect, the illuminance meter measured, in a mine roadway light source is below the surface measured illuminance only 3.91x. The environment is dark, can barely distinguish objects contour, in the yellow light, with a lot of mineral color is not correct recognition.
In order to change this situation, we will be the original 200W incandescent lamp for 50WLED industrial and mining lamps. This is the new fourth generation light source. It is relative to the incandescent lamp has the following aspects of improvement:
(1) saving 50% - 90%: the LED mining lamp adopts the light emitting electromagnetic induction with the IC control electronic rectifier, has the characteristics of high efficiency, high power factor and high power.
(2) long life: LED industrial and mining lamps are not easy to damage the electrode and the filament, the service life of the lamp depends on the rectifier components of the service life, the normal working life of 100000h, is 100 times of the incandescent lamp.
(3) can be a moment to start: LED industrial and mining lights can be instantly activated and hot start, start speed up to millisecond.
(4) no glare and stroboscopic, can protect eyesight: when the operating frequency of the light source is more than 40kHz, the eyes will not feel flicker. Electrodeless lamp working frequency of 210kHz, while the electrodeless lamp also has a wide range of color temperature 2700-6500K.
(5) excellent optical performance: LED light emitted by the industrial and mining light has a full spectrum, similar to the sun. High efficiency is more than 80lm/w. Constant luminous flux, luminous maintenance rate of 95% 2000h, 20000h luminous maintenance rate 84%, 100000h luminous maintenance rate 63%.
(6) good color reduction: in daily work and life, in addition to achieve the "bright" standard, in many applications should also achieve the "true" effect, that is, the color of the light source is high. (7) high luminous flux, with minimal power can be the biggest light effect.
The replacement of LED lighting effect is remarkable Through the improvement of the mine lighting, than the original lighting saving more than half of the electricity costs and working efficiency has been improved. Obviously, mine lighting is very important to improve the working efficiency of workers and reduce mine safety accidents. And in fact mine lighting long ignored by people, the old mining source, lighting method monotone, on the role of mine lighting the lack of research, these factors led to the mine safety accident prone, million people accident rate is high, the increasingly serious trend. Fully understand the importance of lighting to the mine safety, to carry out the research on the problems of mine lighting, determine the reasonable mine lighting system, can effectively eliminate the common mine safety accidents, improve the mine safety status, in this also for enterprises to bring huge economic and energy benefits.
The scheme can also be applied to the workshop, workshop, warehouse, highway toll stations, gas stations, large supermarkets, exhibition halls, stadiums, construction sites, mining areas and other places of lighting. Universal light is led lighting lamps professional manufacturers, home lighting and commercial lighting / engineering lighting solutions experts to solve, continue to flip consulting.
