Industrial plant lighting design based on LED lighting (Figure)

This design workshop is machined and assembled.

The evaluation of lighting quality mainly includes evaluation standards such as illumination level, illumination uniformity, glare interference and color rendering. The following four aspects of LED light source are analyzed in depth.

Architectural lighting specifications require that the design illuminance value be compared with the illuminance standard value, which may have a deviation of -10% to 10%. From the simulation illuminance diagram, it can be seen that the average illuminance of the scheme is 275lx, which is within the range of 270~330lx. 300lx standard. From the perspective of illumination level, the solution can meet the needs of production lighting.

The architectural lighting design standard requires that the general illumination illuminance uniformity in the industrial construction work area should not be less than 0.7, and the illumination uniformity around the work surface should not be less than 0. The average illuminance of the scheme is 0.72.5lx, from It can be seen from the illuminance diagram that the four corners are removed, and the illuminance of all the regions is above 210lx. It can be considered that the general illumination illuminance uniformity in the working area is greater than 0.7. Therefore, the scheme satisfies the specification illuminance uniformity requirement and is suitable for production work. Carry out.

The LED adopts direct current, the light source has simple light color, no ultraviolet light, no glare, and the long-term work has no stroboscopic effect on the human eye.

Color rendering refers to the characteristics of different colors when light sources of different spectra are illuminated on objects of the same color. The higher the color rendering index (圪) of the light source, the better the color rendering performance.

From the architectural lighting design standards, the color rendering index of the design industrial production plant was found to be 80. The LED color index of the LED mining lamp used in this design is more than 80, meeting the requirements of the specification.

It can be seen from the above various lighting quality evaluation standards that the scheme satisfies the specification requirements and is a reasonable design.

Assume that the working hours of the building lamps are 8h/day and work for 22 days per month. The annual electricity consumption of the two schemes is 690盏 if the NH004 metal halide lamps are used, and the power consumption per lamp is 420W. In contrast, in order to achieve the same illumination, LED mining lamps can save more than 50% compared to metal halide lamps.

The lamps are economically compared.

200 yuan, 600 yuan for a single metal halide lamp, the input cost of LED industrial and mining lamps and metal halide lamps are 1.265 million yuan and 414,000 yuan respectively.

h). The annual electricity bill for LED and metal halide lamps is 219,000 yuan and 490,000 yuan.

3) Replacement costs. The metal halide lamp has a service life of about 2000h, and needs to be replaced once a year. It is calculated according to a bulb of 150 yuan, and the annual cost is 103,500 yuan. The cost of replacing the light bulb personnel is 05,000 yuan per year.

No maintenance or replacement is required.

According to the five-year cost comparison. The cost of LED high bay light is (126.5+5x21.9) yuan = 2.36 million yuan. Metal halides are visible. Although LED primary and secondary lamps are more expensive than metal halide lamps, the overall cost of the five-year lamp is much lower than that of metal halide lamps. Since the LED lamp has a life of up to 50,000 hours, the normal service life is much longer. In 5 years, as the use of time increases, the benefits will become more apparent.

At present, the luminous efficacy of foreign LED lights can be achieved above 200 lm / W 5, I believe that after development, market and technology mature, the application prospects of LED industrial and mining lamps will be better.

Conclusion LED lighting has outstanding advantages in energy saving, environmental protection and economy. In line with the purpose of energy saving, this paper uses LED high-power industrial and mining lamps to design lighting for an industrial factory. The lighting data of the design working surface is obtained by DIALux software simulation. The analysis of quality, energy saving effect and economic data from various angles proves the rationality and economy of the lighting scheme.
