Embodiment

[0057] Data preparation: Take the east reading room on the second floor of a university library as an example. The building specifications of the reading room are 30m long, 22.5m wide, and 4m high. The height of the working surface is 0.75m. %, the reflectivity of the floor is 15%, and there are 65 grid lamps installed in this reading room. Each grid lamp has 4 lamp tubes with a power of 36W. The model of the lamp tubes is YZ36RN25, and the luminous flux of each lamp tube is 2500lm . The utilization coefficient is 0.42, and the maintenance coefficient is 0.62. According to the national standard, the illumination requirement of the library reading room is 150-300lx, and the average illumination of the library is set at 250lx.

[0058] According to the calculation of the lighting design software MatLP5 of Panasonic Company, 9 lights should be laid in the long direction and 6 lights should be laid in the wide direction. The average illuminance in this lighting design scheme is 26...

Abstract

The invention discloses an overall-optimization lighting source arranging method which includes the following steps. Firstly, minimum intervals among adjacent light sources are calculated out according to four light source lighting models and based on the minimum intervals , a first light source is located and a step size of variation of light source intervals is determined in a lighting space; secondly, according to the step size, the intervals among adjacent light sources are changed and whether an illuminance value of a lighting spatial point corresponding to each installation interval meets lighting design standards of a building or not is determined. If yes, the scheme is judged to be reasonable and changing the intervals among adjacent light sources continues, whether an arrangement scheme of a next installation interval is reasonable or not is determined and eventually the maximum interval value which meets the lighting design standards of the building is selected as the maximum arrangement scheme. Thirdly, a plane graph of the maximum arrangement scheme is drawn and maximum illuminance, minimum illuminance, illuminance uniformity and needed electric energy of the scheme are calculated out. The overall-optimization lighting source arranging method has the advantages of being little affected by subjective factors and taking both a spatial overall situation and partial lighting conditions into consideration and being accurate in calculation.

Description

technical field [0001] The invention relates to a method for arranging globally optimized lighting sources, and belongs to the field of lighting design and optimization theory. Background technique [0002] With the improvement of awareness of energy saving and environmental protection, the issue of building energy saving has attracted more and more attention from the society. Behind the huge energy consumption of large-scale building lighting design is the reality of high-density installation of lamps and lanterns. Most of the existing energy-saving technologies start from the transformation of lamps and the introduction of large-scale equipment, which have the disadvantages of complex methods and high cost, and seldom solve the phenomenon of power waste from the perspective of optimizing the layout of space lamps. [0003] At present, the main calculation theoretical basis of indoor lighting design includes point-by-point calculation method, utilization coefficient method...
