INTRODUCTION The primary objective of emergency lighting is the provision of visual conditions
10、that can alleviate panic and facilitate safer evacuation of buildings occupants during the failure of normal power supply/lighting, in clear (non-smoke) and smoke filled conditions. The emergency lighting scheme design should be based on worst conditions (e.g. minimum light output, maximum glare lim
11、its) of the luminaires during operating life and should be based only on direct light from luminaires. The contributions by room surface inter-reflections should be ignored. However, in lighting systems such as indirect luminaires or uplights (used in maintained/combined mode), where the luminaire w
12、orks in conjunction with a reflecting surface, the first reflection should be taken as direct light from the system and subsequent reflections should be ignored. The requirements given in this standard are a minimum for design purposes and are calculated for the full rated duration period and end of
13、 design life of the equipment. A special chapter for smoke is included. Safety signs may also fulfil further functions within maintained operation. In most countries, states or towns statutory regulations relating to emergency lighting already exist. For this reason, the appropriate authority should
14、 always be consulted before commencing the design of a specific emergency lighting system. It is hoped that by providing an international standard, lighting technical requirements in local statutory regulations will converge on that standard. 2. SCOPE This standard specifies the luminous requirement
15、s for emergency lighting systems installed in premises or locations where such systems are required. It is principally applicable to locations where the public or workers have access. 3.

ESCAPE LIGHTING To provide visibility for evacuati
28、on, lighting is required in the volume of the space. Safety signs that are provided at all exits intended to be used in an emergency and along escape routes shall be illuminated to indicate unambiguously the route of escape to a point of safety. Where direct sight of an emergency exit is not possibl
29、e, an illuminated safety sign (or series of signs) shall be provided to assist progression towards the emergency exit. An escape lighting luminaire complying with IEC 60598-2-22 shall be sited to provide appropriate illuminance near each exit door and at positions where it is necessary to emphasize
30、potential danger or the location of safety equipment. The places for which emphases shall be considered are listed as the following: a) at each exit door intended to be used in an emergency; b) at stairs so that each flight of stairs receives direct light including especially the top and the bottom
31、steps; c) at any other change in vertical level; d) at mandatory emergency exits and safety sign locations; e) at each change of direction; f) at each intersection of corridors; g) at each final exit; h) at each first aid post; i) at each piece of fire fighting equipment and call point; j) if smoke
32、is of prime concern, it is recommended to mount luminaires at least 0,5 m below the ceiling (see also Chapter 11). Positions denoted as b, c, h, and i, if not on the escape route nor in an open area shall be illuminated to 5 lx minimum at the floor. CIE S 020/E:2007 4 CIE, 2007 - All rights reserved
33、 6. ESCAPE ROUTE LIGHTING 6.1 For escape routes up to 2 m in width, the horizontal illuminance on the floor along the centre line of an escape route shall not be less than 1 lx and the central band consisting of not less than half of the width of the route shall be illuminated to a minimum of 50 % o
34、f that value. NOTE: Wider escape routes can be treated as a number of 2 m wide strips or be provided with open area (anti-panic) lighting. 6.2 The ratio of the maximum to the minimum illuminance along the centre line of the escape route shall not be greater than 40 : 1. NOTE: To prove the ratio a gr
35、id system should be used according to CIE S 015, chap. 4.3.3. 6.3 Disability glare shall be kept low by limiting the luminous intensity of each luminaire within the field of view during the maximum lumen output in emergency mode of operation. For horizontal escape routes, the luminous intensity of t
36、he luminaires shall not exceed the values in Table 1 within the zone 60 to 90 from the downward vertical at all angles of azimuth (see Fig. 2). For all other escape routes and areas, the limiting values shall not be exceeded at any angle (see Fig. 3). 1 = glare zone Fig. 2. Glare zone. 1 = glare zon

If the visual task, or the risk to people, requires a longer duration, 180 min is recommended. Response time: The emergency
40、 escape route lighting shall reach 50% of the required illuminance level within 20 s and full required illuminance within 60 s. If the visual task, or the risk to people, requires a shorter response time, for reaching the 50% level, a shortening of the response time to 5 s is recommended. 7. OPEN AR
41、EA (ANTI-PANIC) LIGHTING 7.1 The horizontal illuminance shall be not less than 0,5 lx at the floor level at each point of the empty core area which excludes a border of 0,5 m of the perimeter of the area. 7.2 The ratio of the maximum to the minimum anti-panic area lighting illuminance shall not be g
42、reater than 40 : 1. NOTE: To prove the ratio a grid system should be used according to CIE S 015, chap. 4.3.3. 7.3 Disability glare shall be kept low by limiting the luminous intensity of the luminaires within the field of view during the maximum lumen output in emergency mode of operation. These sh
43、all not exceed the values in Table 1 within the zone 60 to 90 from the downward vertical at all angles of azimuth (see Fig. 2). 7.4 In order to identify safety colours, the minimum value for the colour rendering index Rafrom a lamp shall be 40. The luminaire shall not substantially subtract from thi
44、s. 7.5 The duration and response time should conform to national requirements. NOTE: If these do not exist then the following minimum is recommended: Duration: 60 min. Response time: The open area (anti-panic) lighting shall reach 50% of the required illuminance level within 20 s and full required i
45、lluminance within 60 s. If the visual task, or the risk to people, requires a shorter response time, for reaching the 50% level, a shortening of the response time to 5 s is recommended. CIE S 020/E:2007 6 CIE, 2007 - All rights reserved 8. HIGH RISK TASK AREA LIGHTING 8.1 In areas of high risk, the
46、maintained illuminance on the reference plane shall be not less than 10 % of the required maintained illuminance for that task; however, it shall not be less than 15 lx. It shall be free of stroboscopic effects. NOTE: Some critical areas (e.g. medical operating rooms) may require up to 100 % of the
47、maintained illuminance of the specific task. For this purpose, the values in Table 1 do not apply. 8.2 The ratio of the maximum to the minimum of the high risk task area lighting illuminance shall not be greater than 10 : 1. 8.3 Disability glare shall be kept low by limiting the luminous intensity o
48、f the luminaires within the field of view during the maximum lumen output in emergency mode of operation; these shall not exceed the values in Table 1 within the zone 60 to 90 from the downward vertical at all angles of azimuth. 8.4 In order to identify safety colours, the minimum value for the colo
49、ur rendering index Ra of a lamp shall be 40. The luminaire shall not substantially subtract from this. 8.5 The duration and response time should conform to national requirements. NOTE: If these do not exist then the following minimum is recommended: Duration: 60 min. Response time: High risk task area lighting shall be the required full illuminance permanently or within 0,5 s depending upon the application. 9.
