It gives criteria for appropriate lighting values only. The designer must take into account all the other
27、requirements of the authorities concerned. The objectives of lighting for exterior work areas are to ensure: - efficient working conditions, - safe movement and traffic, - safety and security of people and property. 2. Basic requirements 2.7 Illuminance and luminance Visual performance improves with
28、 an increase in the size of details examined, the luminance contrast between details and the adaptation level (.e. the average background luminance). Characteristics of the object examined can rarely be changed, but are worth considering, whenever possible. For example, larger signs, light colours a
29、gainst dark background or vice versa. The visual environment is generally too complex to allow a calculation of luminance. As luminance is defined as an effect of illuminance on a surface with certain reflection properties, illuminance is generally used as design criterion. Illuminance values in thi
30、s guide are generally considered as horizontal values at the height of the work task. If it is not known, use 1 m above ground level. For traffic areas all the values are speCmed at ground level. As visual tasks often rekr to planes other than horizontal, the typical elevation angle of the object ex
31、amined should be used. 2.2 Unifomiity of illuminance Since it takes time to adapt to low luminance levels, large luminance differences in the visual field reduce visibility, particularly by alternating bright and dark visual objects. Uniformity rau0 is generally defined as the ratio of minimum to av

34、GR, the better the glare restriction is. Further information can be found in Publication CIE 112-1994. The recommended glare limiting values GR for different visual and work tasks on exterior work areas are given in Table 3.1. For viewing tasks of decisive importance or long viewing periods in work
35、areas it is advisable to use glare rating values lower by 5 units than the GR, If observers positions are known, then the calculation should be made for those is the average luminance of the area observed (cdm); is the average reflectance of the area (usually 0,2); is the average horizontal illumina

If yi 70“ then d=h/3, if y7Oo then the mounting height is not higher than 15 metres; the luminaires are not inclined more than 5“ upwards from the horizontal.

39、ntal. The main viewing direction(s) of the specifc task should be chosen. If it is not known, all the eight directions should be calculated to identify the greatest glare. 2.4 Colour quality The colour quality of light sources is characterised by colour appearance and colour rendering. The colour ap
40、pearance of the light can be described by the correlated colour temperature (K). Colour rendering of lamps is often described by the general cobur rendering index (&=O to IOO), or by colour rendering classes (Class I to 4). Table 2.2 shows the colour rendering classes and typical applications. Data
41、for colour rendering of light sources should be sought from the manufacturers. 2.5 Maintenance The average illuminance should not fall below a value called maintained average illuminance. It is specified as an average illuminance at the time maintenance must be carried out. Maintenance factor is the
42、 ratio of the illuminance at the time maintenance must be carried out to the illuminance when the installation is new. All the illuminance values given in this report are maintained values, except those used for calculation of glare rating (Chapter 2.3.). 4 STD=CIE L29-ENGL 1998 900b145 0005954 767

Recommendations: Choose the most energy-efficient solution. Switch off lights when not
46、 required. Direct light below the horizontal, wherever possible to illuminate the object to be lit. If there is no alternative to up-lighting, then the use of shields and baies will help keep spill light to a minimum. Use specially designed lighting equipment that, once installed, minimise the sprea
47、d of light near to or above the horizontal. Do not over light. Keep to the Guide for lighting tasks. Pay special attention to recycling faulty light sources and other components to avoid environmental pollution. Search for and follow all the standards and recommendations on environmental protection
48、relevant to the area of lighting design. 5 CIE 129 - 1998 2.7 Design The point-by-point calcu!ation method should be used to obtain an average illuminance value and uniformity ratios. The calculation area should be divided into a rectangular grid. (Figure 4.) Grids approximating a square are preferr
49、ed, the ratio of length to width of a grid cell should be kept between 0,5 and 2. The maximum grid cell size ) should be and prlO where d is the width of the calculation area (in metres). p is the maximum grid cell size (in metres). The horizontal illuminance is calculated on the average height of the task. If no specific task is defined the calculation height is lm above ground level, for traffic areas on ground level. In the case of irr
