17、ses of this standard emergency lighting is regarded as a generic term of which there are a number of specific forms, as shown in Figure 1.Figure 1 Specific forms of emergency lightingThe overall objective of emergency escape lighting is to enable safe exit from a location in the event of failure of
18、the normal supply. The objective of each form within this category is as follows. The objective of escape route lighting is to assist the safe exit from a location for occupants by providing appropriate visual conditions and direction finding on escape routes and in special locations, and to ensure
19、that fire fighting and safety equipment can be readily located and used. The objective of emergency lighting of escape route safety signs is to provide appropriate visual conditions and direction finding to assist escape routes to be readily located and used. The objective of open area (anti-panic)
20、lighting is to reduce the likelihood of panic and to enable safe movement of occupants towards escape routes by providing appropriate visual conditions and direction finding. The flow of light for escape routes or open areas should be downward to the working plane but illumination should also be pro
21、vided to any obstruction up to 2 m height above that plane. The objective of high risk task area lighting is to contribute to the safety of people involved in a potentially dangerous process or situation and to assist proper shut down procedures to be carried out for the safety of other occupants of
22、 the location.There are techniques that may be used as a supplement and when applied to escape routes in addition to conventional emergency lighting luminaires can enhance their effectiveness in an emergency. These techniques are not included in this standard.Vision varies from person to person, bot
23、h by the amount of light required to perceive an object clearly and in the time taken to adapt to changes in the illuminance. In general, older people need more light and take a longer time to adapt to low illuminance on a hazard or escape route.Much anxiety and confusion can be alleviated by strate
24、gically placed signs indicating the way out of a location. It is very important that exits are clearly signposted and are visible, whenever the location is occupied.#BS EN 1838:2013EN 1838:2013 (E)8sz80gzOSBO0uo -P。JXojo Al-SJ 60-jd-XdoP3SU81 ScopeThis European Standard specifies the luminous requir

37、ntained in accordance with EN 60598-2-22, EN 50172 and EN 62034.The requirements given in this standard are maintained minimum values and are calculated for the full rated duration period at the end of the design life of the equipment and the inter-reflected light contribution shall be ignored.The e
38、mergency lighting scheme design should be based on worst conditions (e.g. minimum light output, maximum glare limits) 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 l
39、ighting systems such as indirect luminaires or uplights (used as an emergency Iuminaire in maintained mode) where the Iuminaire works in conjunction with a reflecting surface, the first reflection (based on the maintained reflectance) may be taken as direct light from the system and subsequent refle
40、ctions shall be ignored.To provide visibility for evacuation purposes lighting is required in the volume of the space. 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 place of saf
41、ety. In this standard the requirement is fulfilled by mounting the luminaires for lighting and the escape route safety signs at least 2 m above the floor.8sz80gzOSBO0uo -P。JXojo Al-SJ 60-jd-XdoP3SU8Where practical, for ease of seeing, the safety sign should be mounted not higher than 20 above the ho
42、rizontal view according to the maximum viewing distance of the sign.To ensure that emergency lighting operates when required it shall be installed, tested and maintained in accordance with EN 50172 and if automatic test facilities are installed they shall be in accordance with EN 62034.Where direct
43、sight of an emergency exit is not possible, an illuminated directional sign (or series of signs) shall be provided to assist progression towards the emergency exit.An escape lighting Iuminaire conforming to EN 60598-2-22 shall be sited to provide appropriate illuminance near each exit door and at po
44、sitions where it is necessary to emphasize potential danger or safety equipment. The positions to be emphasized shall include the following.4.1.2 Points of emphasisThe points of emphasis when placing lighting devices are:a) near (see NOTE 1) each exit door intended to be used in an emergency;b) near
45、 (see NOTE 1) stairs so that each flight of stairs receives direct light;c) near (see NOTE 1) any other change in level;d) Externally illuminated escape route safety signs, escape route direction signs and other safety signs needing to be illuminated under emergency lighting conditions;e) at each ch
46、ange of direction (see NOTE 2);f) at each intersection of corridors (see NOTE 2);g) near (see NOTE 1) to each final exit and outside the building to a place of safety;h) near (see NOTE 1) each first aid post; so that 5 Ix vertical illuminance shall be provided at the first aid box;i) near (see NOTE
47、1) each piece of fire fighting equipment and call point so that 5 Ix vertical illuminance shall be provided at the fire alarm call points, fire fighting equipment and panel.j) near (see NOTE 1) escape equipment provided for the disabled; andk) near (see NOTE 1) disabled refuges and call point. Also to include disabled refuge two way communication systems including disabled toilet alarm call position.NOTE 1For the purpose of this clause near is normally considered to be within 2 m measured horiz
