Under the national energy conservation and emission reduction policy, the promotion of energy-efficient and efficient light sources has become the main line of lighting applications in various industries. In the field of industrial lighting, the use of energy-saving green lighting equipment to replace traditional light sources has also become the consensus of enterprises. However, the use of energy-saving lighting also needs to pay attention to distinguish the lighting environment. According to different enterprise processes and the environmental characteristics of these processes, the most suitable lighting products are used to achieve their respective advantages, in order to achieve the best lighting effect and optimization. energy saving effect.
In the field of industrial lighting, the environment for industrial production is more complicated. The height is three to five meters, which is called the low ceiling. If the height is more than ten meters, it is called the high ceiling. Depending on the height, the illuminance and luminous efficacy of the required light source in the industrial production area are also different. The appropriate light source can be used to meet the needs of production, to bring a comfortable and pleasant working environment for workers, and to reduce the error rate, thereby improving production. effectiveness. At present, many users use one of the hottest light sources (QL electromagnetic induction lamp) in various lighting environments, and regard it as a universal light source that can replace various lightings, although the electrodeless lamp is a good kind. The light source, but it is not a panacea, there are specific occasions for its application. Philips Lighting, which has sufficient research and understanding of industrial lighting, recommends that quality lighting solutions be tailored to the actual production conditions and use different energy-efficient lighting products to meet the needs of different industrial production environments.
In the high ceiling lighting environment, such as the tall main building, because of the large space span, the illumination of the light source is required to be high, and the light efficiency is high, so as to ensure sufficient light in the production, and the number of lighting products required in the high ceiling lighting environment is huge. Therefore, the energy saving of the light source is very important. To measure whether a light source is energy-saving depends first on the light efficiency (Lm/w) of the light source, and secondly on whether the size and shape of the light source can be more effectively utilized by the luminaire. Which of the metal halide lamps and electrodeless lamps in the high ceiling environment is more energy-efficient? Metal halide lamp has excellent luminous efficiency, the luminous efficiency is about 75-106lm/w, the light source life is 80,00-20,000 hours, the reflection efficiency of the lamp can reach 80%, and the color rendering is good, ensuring the lighting environment is bright enough. Light, the owner saves a lot of electricity costs, so it is the first choice for high ceiling lighting. The electrodeless lamp is a body (surface) light source with a maximum luminous efficiency of 80-90 lm/w and a light source life of 60,000 hours. Due to its large light-emitting area and dispersion, it is difficult for the lamp to have accurate light distribution, and the reflection efficiency is only 70%. In fact, in the practical application of tall buildings, it is not energy-saving, and it is not the best choice for high ceiling lighting.
In the field of low ceilings, light sources with good color rendering and avoiding glare and high uniformity can enable workers to concentrate, even if they work for a long time without fatigue, reducing the error rate and accident rate. Fluorescent lamps are not only efficient, but also have a long service life, good color rendering, good color and comfort, can effectively avoid glare, and bring bright and even comfort light. It is the main lighting solution for low ceiling lighting environment, which can be used in control room. Office and other areas. Fluorescent tubes with super-lifetime have been available on the market. In contrast, the electrodeless lamps have a long life, but the price is relatively high and the cost performance is relatively low.
In addition, electromagnetic interference is also a factor that owners can't ignore when choosing lighting equipment. Electromagnetic wave interference may affect the normal operation of equipment, affect the accuracy of data transmission, and form a safety hazard. Since the electrodeless lamp is composed of a bulb, a coupling, and a high-frequency power source, no filament is illuminated by a magnetic field. If a large amount of use is likely to cause electromagnetic interference, an undetermined interference is formed to the electronic device, the power grid, and the control device. For example, the cargo warehouse of Shenzhen Baoan Airport used the induction lamp, but the electromagnetic interference was serious, which affected the navigation equipment. Finally, all the metal halide lamps were replaced. Different energy-saving lighting products have their own unique advantages and play their role in a specific lighting environment. The electrodeless lamp also has its specific application, because it has a long life, no stroboscopic, and the light output is stable and is not affected by the voltage condition. Therefore, the electrodeless lamp is suitable for general lighting in the room, can be used to install a place with a low height, and the temperature is constant, especially in a place where the light is not turned off.
High-quality lighting solutions can open up and reduce expenditures for enterprises, improve the working environment of employees, and improve work efficiency. It is the invisible green production power of enterprises. According to the specific lighting environment, the lighting solution can be selected correctly, and the advantages of lighting can be fully utilized.
