Comparison of Illumination Survey Data of Field (Practical) with Developed MATLAB for Conventional and LED Lighting System in Both Open Cast and Underground Mines-A Case Study
The primary importance of this paper is to define the serious problems faced in mine lighting application and to provide guidance and solution of the problems. In lighting design, the primary goal is to cater a visual environment in which people may efficiently perform specific tasks and receive agreeable visual impressions. The process of design is a comparison of various alternative systems, trading off their benefits for their cost in accomplishing their goals. The Illuminating Engineering Society of North America (IESNA) has recommended some design practices for lighting. Although the eye is able to make use of wide range of light levels, there are certain conditions under which it works best. Good artificial lighting system influences the condition of seeing, which facilitates in reducing labours mental tiredness, protecting their health, eyes and nervous system, and reducing injury. These benefits tend to offset the cost economics of lighting or it may be many times greater than the cost of the lighting. A brief explanation of different LED product. By comparing the LED with Incandescent source for the distribution of luminous lux for the given area for lighting fixture at a tilt angle of 0? with the readings noted it is concluded that LED meets the required lux level in the surface mines as per the DGMS standards with the conservation of power. The present day LED has its features such as less power consumption, more lumen output, high efficacy and its life time is 100 times more as compared to incandescent and 10 times more as compared to CFL Light sources. Also the colour considerations for the LED gives the perfect visibility for the human eye gives the pleasant working environment with safety, increases production and reduces the accidents in the surface mines. To achieve the good requirement of illumination in mines, planed illumination is required to be enabled using suitable rules with guidelines so that effective decision can be considered in mines
