DINEN 12464-2:2014-05EN 12464-2:2014 (E) 4Introduction To enable people to perform outdoor visual tasks efficiently and accurately, especially during the night, adequate and appropriate lighting should be provided. Th

28、e degree of visibility and comfort required in a wide range of outdoor work places is governed by the type and duration of activity. This standard specifies requirements for lighting of tasks in most outdoor work places and their associated areas in terms of quantity and quality of illumination. In

29、addition recommendations are given for good lighting practice. It is important that all clauses of the standard are followed although the specific requirements are tabulated in the schedule of lighting requirements (see Clause 5). DIN EN 12464-2:2014-05 EN 12464-2:2014 (E) 5 1 Scope This European St

30、andard specifies lighting requirements for outdoor work places, which meet the needs for visual comfort and performance. All usual visual tasks are considered. This European Standard is not applicable for emergency lighting; see EN 1838 and EN 13032-3. This European Standard does not specify lightin

31、g requirements with respect to the safety and health of workers at work and has not been prepared in the field of application of Article 153 of the EC treaty, although the lighting requirements, as specified in this standard, usually fulfil safety needs. Lighting requirements with respect to the saf

32、ety and health of workers at work may be contained in Directives based on Article 153 of the EC treaty, in national legislation of member states implementing these directives or in other national legislation of member states. This European Standard neither provides specific solutions, nor restricts

33、the designers freedom from exploring new techniques nor restricts the use of innovative equipment. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

36、ia 4.1 Luminous environment For good lighting practice it is essential that, in addition to the required illuminance, other qualitative and quantitative needs are satisfied. Lighting requirements are determined by the satisfaction of three basic human needs: visual comfort, where the workers have a

37、feeling of well-being; in an indirect way also contributing to a high productivity level, visual performance, where the workers are able to perform their visual tasks, even under difficult circumstances and during longer periods, safety. Main parameters determining the luminous environment are: lumi

38、nance distribution,DIN EN 12464-2:2014-05 EN 12464-2:2014(E)6 illuminance, glare, directionality of light, colour rendering and colour appearance of the light, flicker. Values for illuminance and its uniformity, discomfort glare and colour rendering index are given in Clause 5; other parameters are

39、described in Clause 4. NOTE Intentionally improved and designed luminous environment, glare-free illumination, good colour rendering, high contrast markings and optical and tactile guiding systems can improve visibility and sense of direction and locality. See CIE 196:2011. In addition to the lighti

40、ng, there are other visual ergonomic parameters which influence visual performance, such as: the intrinsic task properties (size, shape, position, colour and reflectance properties of detail and background), ophthalmic capacity of the person (visual acuity, depth perception, colour perception), Atte

41、ntion to these factors can enhance visual performance without the need for higher illuminance. 4.2 Luminance distribution The luminance distribution in the visual field controls the adaptation level of the eyes, which affects task visibility. A well balanced luminance distribution is needed to incre

42、ase: visual acuity (sharpness of vision), contrast sensitivity (discrimination of small relative luminance differences), efficiency of the ocular functions (such as accommodation, convergence, pupillary contraction, eye movements). The luminance distribution in the visual field also affects visual c

43、omfort. Sudden changes in luminance should be avoided. 4.3 Illuminance 4.3.1 General The illuminance and its distribution on the task area and the surrounding area have a great impact on how quickly, safely and comfortably a person perceives and carries out the visual task. All values of illuminance

44、s specified in this standard are maintained illuminances and will provide for visual comfort, visual performance and safety needs. All illuminance average and uniformity values are dependent upon the grid definition (see 4.3.4). 4.3.2 Illuminance on the task area The values given in Clause 5 are mai

45、ntained illuminances over the task area on the reference surface, which may be horizontal, vertical or inclined. The average illuminance for each task shall not fall below the value given in Clause 5, regardless of the age and condition of the installation. DINEN 12464-2:2014-05EN 12464-2:2014 (E) 7

46、 The values are valid for normal visual conditions and take into account the following factors: psycho-physiological aspects such as visual comfort and well-being, requirements for visual tasks, visual ergonomics, practical experience, safety, economy. The value of illuminance may be adjusted by at

47、least one step in the scale of illuminances (see below), if the visual conditions differ from the normal assumptions. A factor of approximately 1,5 represents the smallest significant difference in subjective effect of illuminance. The recommended scale of illuminance (in lx) is: 5 10 15 20 30 50 75

48、 100 150 200 300 500 750 1 000 1 500 2 000 The required maintained illuminance should be increased, when: visual work is critical, visual task or worker is moving, errors are costly to rectify, accuracy or higher productivity is of great importance, the visual capacity of the worker is below normal, task details are of unusually small size or low contrast, the task is undertaken for an unusually long time. The required maintained illuminance may be d
