Application of European standard metal halide lamp system in industrial lighting

Abstract This paper mainly introduces the application of the European standard metal halide lamp system in industrial lighting. It improves the production efficiency and greatly reduces the total cost of the owner while improving the lighting environment. The product and its application have been deeply explored from the introduction of the characteristics of the lighting system.

The task of factory lighting is to ensure good visibility in the work environment. Outstanding lighting makes work safer and easier, reducing accidents, reducing the level of faults and substandard products, and increasing productivity. In addition, the pleasant working environment created by good lighting motivates employees to improve product quality and yield. (plus energy saving content)
The European standard metal halide lamp in the high-intensity gas discharge lamp series has a strong vitality with high luminous flux, high efficiency, long life and small illuminant, and has made an important and positive contribution to high-quality industrial lighting.

Product description of metal halide lamps, mercury lamp ballasts and sodium lamp ballasts

Metal halide lamps are based on high pressure mercury lamps, adding some metal halides (such as antimony, indium, etc.) to the arc tube. These halides are involved in discharge luminescence during operation. By blending the composition and ratio of the metal halide, various full-spectrum (white light) light sources can be obtained. Philips Euro-standard metal halide lamp HPI BU Plus is suitable for both mercury lamp line and sodium lamp line. It is very convenient to replace, completely eliminating the trouble and extra cost of modifying the line. Moreover, it not only has a long life of 20,000 hours, but also has high luminous efficiency and good lumen maintenance, which can greatly save power consumption and maintenance costs. (See Table 1 for related parameters)

Philips Metal Halide Ballasts BHL and BSN are particularly suitable for the Chinese market, with low noise, over-pressure and high temperature resistance. All models have a slightly curved base to ensure a strong and shock-proof two-point installation; The surrounding micro-protrusions ensure good contact of the ballast when it is screwed to the conductive plate, eliminating the need to install a separate ground wire; the design is compact and simple, leaving no trace of decoration.

Advantages of the European standard metal halide lamp (HPI-BU Plus 250W) system in practical applications:
Suppose a factory originally used a sodium lamp line, installed 500 watts of 1000 watt spotlights, local industrial lighting power of 0.7 yuan / kWh, a day of lighting time of 8 hours, then a monthly electricity bill of 84,000 yuan . After using the Philips European standard metal halide lamp system, 500 watts of European standard metal halide lamp with a power of 250 watts was installed on the basis of the original sodium lamp line. The monthly electricity bill was 21,000 yuan. One month's electricity consumption is only a quarter of the original, and the service life is 2-3 times higher than the original, reaching 20,000 hours. In this way, the factory can recover the investment cost of the initial purchase of these lamps by saving electricity and reducing maintenance costs in a short time.
System application of Philips flagship product HPI-BU Plus250W European standard metal halide lamp: the light output on the mercury lamp line is increased by 50%, and the sodium lamp line is increased by 100%. The huge improvement of color rendering increases the visual comfort of industrial lighting. If it is installed on the existing foundation, the lighting level can be increased at the lowest cost; for the new system installation, only a small number of lamps can achieve the specified illumination level, which greatly reduces the installation and maintenance costs. At the same time, the unique low-pulse trigger technology is used, which greatly increases the safety factor used in the factory; the simple design makes installation and maintenance easier, increases production efficiency, and correspondingly reduces the overall investment cost. Just like the basic connotation of green lighting engineering: energy saving, high efficiency, comfort, safety and environmental protection.
Before the renovation of the Taiyuan Iron and Steel Plant, the architectural lighting design standards of the 1970s were used. In addition, the company pays insufficient attention to the lighting of the factory, and most of them use self-ballasted mercury lamps, incandescent lamps and mixed lights. Lighting technical parameters such as color rendering and color temperature of the light source are basically not considered. Just consider the convenience of self-ballasted mercury lamps and incandescent lamps for maintenance and replacement.
In addition to the cold rolling workshop, the whole working environment, such as hot rolling, steel making, blast furnace, sintering, etc., has large dust and high heat, which has high requirements for the protection performance of the lamps, and there are almost no self-ballasted mercury lamps and mixed lamps. Any protection, this has a very large impact on the service life of the luminaire. In addition, the reflection efficiency of the luminaire reflector is also a key factor in evaluating the quality of the luminaire. In the past, the reflector used in the luminaire was only a layer of iron, which was very inefficient.
After comparison, the engineers found that the luminous flux of the 250W self-ballasted mercury lamp is only 1/4 of that of the 250W HPI metal halide lamp under the same power. The color rendering index and the average life are not comparable.
After redesigned by lighting, Taiyuan Iron and Steel Plant refers to CIES008/E-2001 indoor workplace lighting standard, iron and steel industry indoor illumination 200Lux, selects MDK900 series high ceiling lamp with Philips protection grade IP65, with HPI metal halide lamp, the result is only A quarter of the original mercury lamp is required to meet the CIE standard.
Especially after the actual use of the hot rolling workshop with poor working environment, the on-site staff reflected that the workshop environment was more humane than the original, and felt that the workshop was brighter and the light was more natural and soft. At the same time, the working status and work efficiency of the staff Also improved. How much electricity savings did the engineering staff reflect? Installation and maintenance is more convenient? More worry?
