Some luminaire manufacturers have weak technical strength, do not pay attention to standardized production, and the degree of standardization is not high. The design of luminaires is unreasonable = or by copying other people's products, the light distribution curve is unreasonable, the pursuit of lowering the production cost, the selection of materials is poor, and the reflectors are inferior. Aluminum plate or stainless steel, easy to oxidize, adsorb dust or rust, serious glare, low reflection efficiency, no power factor compensation, low power factor, poor quality. The use of such so-called high-quality light sources can not guarantee the expected lighting effect and energy-saving purposes. For indoor luminaires, the luminous flux that is directly reflected on the working surface and the total luminous flux emitted by the light source inside the luminaire Compared with the general luminaire manufacturer, after the luminaire test, the data is provided in this area. The accuracy of the utilization factor is large. The influence of the calculation result is very large. The influence factor has the following factors: the light distribution curve of the luminaire = the light of the luminaire Output ratio = indoor reflectivity å¤ ã€, wall, work surface Some manufacturers can not provide this data due to technical strength, equipment conditions, or provide a light distribution curve can not truly represent the actual production of the light distribution curve. In addition, in the current design manual, the light distribution curve and utilization coefficient data of the luminaire are basically still tested and calculated by some units of the commonly used lamps and light sources produced at the time in Beijing and Shanghai at the Institute of Physics of the State Construction Committee. The various lamps and lanterns made by the factory are a series of data to calculate charts and data, so it is far from meeting the calculation requirements of the current lamps and light sources. There are many factors affecting the accuracy of the utilization coefficient, and the calculation results have large errors. This method is generally only used for preliminary design to calculate the average illumination and determine the number of lamps.
In the design of lighting earthwork, some complex lighting calculations require technical support from the lighting manufacturer and research department. Because the optical characteristics of some special lamps are not easy to be fully understood and mastered by the engineering designers, it is necessary for the designers and the professional technicians of the lamps and lanterns to cooperate with each other to learn from each other and work together to make the lighting design. According to their own characteristics and advantages, the transformation pattern of multi-materials and multi-party cases has been increasing rapidly with the increase of sulfur production by oil and natural products. The world sulfur market has been showing a situation of oversupply, the price of sulfur in the international market. There is also a steady decline in the domestic production and commissioning of more than one large-scale pyrite sulphuric acid plant. The pyrite market is in a state of tight supply, declining grade, rising prices and difficult transportation. Therefore, the import of sulfur is actively and cautiously used as a supplement to China's sulfur resources. The small one can only alleviate the shortage of domestic sulfur resources, and it will bring good economic benefits and significant environmental benefits to the enterprise. The scale of the equipment after the transformation and the utilization mode of the old equipment were discussed, and the investment required for the unit output after the transformation was analyzed. 3 Relevant disciplines were strengthened and coordinated. Lighting design The design of electrical lighting designers began with the design. Architects and related professional designers will carry out architectural project demonstrations, deepen understanding of the use and function of buildings and facilities, listen to the opinions of architects and other professional design personnel, and explain what kind of lighting space the architect intends to have. It is only the functional environment that pays attention to the function, or the comfortable environment that emphasizes the three-dimensional sense. The space for the original atmosphere that the architect wants to create should also be well understood. At the same time, the electric lighting designers should also request in advance. Architects have a good understanding of lighting equipment, lighting, methods, etc., and technical design methods, as well as economics. The light environment of the building needs to be created by the architect and the electric lighting designer to jointly maintain the integrity and high quality of the space. In the lighting design of the Nanjing Lukou International Airport terminal, the electric lighting designer is according to the architect’s The concept of ubiquity and the use of functional requirements, according to the use of the building space environment, visual effects and artistic ideas to determine the lighting method, light source type, lighting and light distribution, the building, the use of functions, lighting organic Combine the ground and use it correctly. The hall and the departure hall are illuminated by the “upward†illumination of the lamps. The entire hall is bright and the light is soft. There is no glare and obvious shadows, creating a harmonious atmosphere and artistic conception of the architectural space environment, fully reflecting the modern terminal building. The style of the architectural space enhances the aesthetics of the architectural art and creates an ideal light environment.
