When doing shopping mall lighting design, the first thing to consider is the illumination level, followed by the decoration and light color effects, as well as the contrast between light and dark and the emphasis on lighting. Design types generally fall into two categories: one is functional lighting, such as supermarkets, warehouse-style shopping mall lighting, etc., such lighting generally maintains the entire illumination area at a constant illumination level; the other is decorative lighting, which requires Distinctive personality and characteristics, such as specialty stores, jewelry store lighting, etc., the role of lighting is to attract customers to pay attention to shopping malls or goods, designers need to consider the following when planning or designing a commercial building lighting system Some questions: (1) Can you make the most of natural light (2) Illumination level and color effect in different places and different parts, whether the choice of light and dark contrast is appropriate (3) How to compare the contrast of building exterior lighting (4) Maintenance and testing Is it convenient (5) Is there enough reserved device for future expansion and expansion? (6) Is it in line with the national building lighting standards and safety standards? (7) Is there a convenient selection switch and dimming control system? 3 Domestic and foreign commercial buildings Lighting power consumption based on a sample survey of large commercial buildings in major cities across the country, China photo
Reasonable choice of light source electric light source is the core and main body of high-efficiency lighting. The correct choice of light source is very important. The most common way to choose energy-saving light source is to replace ordinary lighting incandescent lamp with halogen halogen lamp; replace incandescent lamp with compact fluorescent lamp; Tube-type fluorescent lamps replace the upgrade of incandescent lamps and straight-tube fluorescent lamps; vigorously promote high-pressure sodium lamps and metal halide lamps. 21 lists the technical characteristics and applicable occasions of different types of electric light source products, which can be used as a reference for selecting a light source. The illumination of the background illumination does not have to be higher than 500Lx per square meter. High-pressure sodium lamp or new sulfur lamp is used to enhance the color rendering, which not only increases the service life of the lamp, but also reduces the maintenance cost. The compact fluorescent lamp or metal halide lamp can be used as a local enhanced lighting shopping mall. External lighting should use efficient lighting as much as possible, such as the use of high pressure sodium lamps and time control switches or photosensitive switch lights.
Energy-efficient lamps, lamp electrical accessories and wiring equipment have been selected. With the continuous emergence and renewal of energy-saving light sources, new types of lighting fixtures and lighting equipment have also been born, and continue to develop into high-efficiency and diversity. The use of energy-efficient lighting fixtures not only saves energy, but also creates a new, high-quality lighting environment and effects. Good maintenance management The lighting system in use requires frequent maintenance management to maximize the efficiency of its work. First, keeping the light source and lamps clean can avoid a certain loss of luminous flux output. According to international definition, the entire lifetime of a light source generally refers to the time zone from when the light source is used until its light decays to 50% of the original light pass. The rate of light decay will increase or decrease depending on the type of lamp and the location of the installation. The length of life will also be affected by factors such as: overheating, frequent opening and voltage fluctuations, which are factors to be considered when maintaining the lighting system. In addition, in the initial stage of lighting design, the possibility and convenience of maintenance should be considered for the selection and location of the lamp. Maintenance work should also include proper disposal of used light sources, and pay sufficient attention to the environmental pollution caused by mercury and other chemicals. At present, the application of fiber optic cable and light guide technology has become a good way to solve the problems of efficiency and maintenance.
Conclusion From the actual lighting conditions of commercial buildings in China, the lighting and power saving levels of various shopping malls and facilities have yet to be further improved. With the proven high-efficiency lighting technology, it is expected that 20% of the energy saving potential in the mall can be tapped.
The latest Windows has multiple versions, including Basic, Home, and Ultimate. Windows has developed from a simple GUI to a typical operating system with its own file format and drivers, and has actually become the most user-friendly operating system. Windows has added the Multiple Desktops feature. This function allows users to use multiple desktop environments under the same operating system, that is, users can switch between different desktop environments according to their needs. It can be said that on the tablet platform, the Windows operating system has a good foundation.
