Pudong International Airport Hall Lighting Design and Energy Saving
Indoors, the light that enables the hall to achieve the purpose of saving electricity during the day is not only the effect of supplementing the indoor cloud. The main hall in the evening is manually divided, that is, the group is used: the abdomen is illuminated, and it is shot on the zenith. In reflecting this effect: Editor's note: At present, many hotels, conference halls, no matter the sun outside the window, but the curtains are covered, a large number of artificial lighting, which is a waste of the board, the magazine published in the 11th to 12th issue of 1999 Introducing the foreign new wave using natural light; today, the editor of the special Pudong International Airport lighting designer Shao Minjie wrote an article introducing the successful experience of using natural light. The site is the largest and most advanced passenger airport built in China. The interior design, architectural form, structural layout, lighting design, color layout and lighting effects of the airport terminal are all fixed. The huge skylighting window makes the 761-deep and 4021-wide main halls white, and the deep blue ceiling looks like a blue sky under natural lighting. There are 704 white steel steel bars under the canopy in the hall. The force piece has a cylindrical shape and introduces the light of the upper square lighting hole to make use of the outdoor natural light. At the same time, the light from the top can also be used to appreciate the blue sky and white lighting design. The purpose and effect are ten [with 704 white steel under the ceiling) Limit the blue light of the illumination as much as possible, just like the blue stalks in the evening, just like the stars, and let the average illuminance of the hall floor be no less than 200LX, and the limitation of glare and ground illumination. The uniformity has certain requirements. The purpose of the hall lighting system is to show the above effects. Realize design ideas and requirements, achieve good realistic results, and pay attention to saving lighting energy. The skylight is a dark blue lead corrugated board. Its light and light rate is white steel and steel. The bottom of the steel belly is connected by rows with steel cables. There are rows at intervals of 91. The zenith of the 3 halls is curved and both sides are off the ground. The ping height is designed by indirect direct mixed lighting, and the hall lighting is divided into main lighting and auxiliary lighting. The main body illumination provides the necessary illumination level for various activities that can be carried out in the building but does not include the local area illumination of the hall. The average illumination value is not less than 200LX and the uniformity of the minimum and maximum illumination ratios should be less than. 4, to ensure a good uniformity of the hall lighting. Auxiliary lighting is mainly used to illuminate the steel web under the ceiling, which fully reflects the architectural effect. As the effect of the building requires that the auxiliary lighting can only illuminate the steel web and should not be too high, the choice of 7 has a metal shading lamp with a light-shielding illumination against the steel web; and as far as possible the vertical of the fixture The diffusion angle is limited to 15. In the 402-wide hall, every 9 sets of lighting installation nodes, there are 90 points on both sides of the high and low sides, each node on the East China Architectural Design and Research Institute, the Minjiejie National Rat II, each set up 5 sets of lights, each The lamp capacity of each node is controlled within 5KW on the high side and 4KW on the low side. Due to the large space and large area, in order to achieve the required illumination and architectural effects, the required lamp power will be larger. For this reason, the choice of the type of illumination source in the hall should fully consider its energy-saving and comfortable lighting environment. The metal toothed lamp "has its characteristics of light efficiency, high brightness, 篼 color rendering, multi-tone, long life, not only becomes the most ideal energy-saving light source, but the county is also a multi-functional and well-developed light source. In addition, Jinzhan Inorganic Lamps have been formed from 7 small powers to high power, low color temperature to high color temperature, from color development to high color rendering, and high-efficiency, long-life and other unique specifications and varieties. A metal factor light source is used in the selection of a large light illumination source. For the high-side node, two sets of 1000W light-type metallized lamps are used for downward illumination, and a set of 400W metallized lamps is used directly as a supplement to the edge side illumination deficiency; two sets of 400-color light are used on the low side. The metallized lamp is used as a downward illumination, and a set of 400W smart metal surface lamps is used to supplement the edge side illumination. In order to meet the building effect, two sets of lOOW suitable metallized lamps are used to illuminate the steel webs at the high and low side nodes, respectively. Since the illuminating light that hits the steel web at the side of the stern side produces a partial downward glare, a patch is added in front of the two sets of lamps to "block the downward glare. The selected metallized lamp has a color temperature of 4000 to 4300K ​​and a color rendering index of R.65. It can be seen that the color rendering of the light is also ideal. According to the above scheme and the arrangement of the lamps, the computer illumination calculation program is available. The illuminance calculation value of the typical plane is calculated. The maintenance coefficient of the luminaire is 0.66. The calculated average illuminance value and the correct control method of the lighting control are effective means to achieve the comfort of the lighting environment, and it is an effective measure for energy saving. For this reason, the main lighting and auxiliary lighting of the entire hall adopt intelligent mode automatic and manual manual control. Intelligent mode control not only uses the light sensor switch to control according to the set illuminance but also according to the progress of the evening flight flow to determine the number of switches and the number of lighting in the hall, so as to maximize the use of natural lighting, Reach the required illumination requirements in the hall and the architectural lighting effect, while saving a lot of power. Fourth, the small space and large space lighting design is different from ordinary lighting. It not only needs to complete the requirements of illumination and brightness in a large space, but also can show the artistic effect of novel, chic and infinite imagination. Therefore, its conception, design, lighting arrangement, and choice of light source will be the key to achieving. In addition, large space lighting as an energy project, its implementation should also proceed from the actual, vary from place to place, fully and effectively use solar energy, correctly and rationally select high-efficiency energy-saving light source, improve the utilization rate of lighting electricity, and obtain a larger period Social and economic benefits, the lighting design of the waiting hall is based on this concept and concept.
