On September 27, 2020, the European Union issued a new version of the emergency lighting standard: EN60598-2-22:2014/A1:2020. The old standard will expire on March 27, 2023.
EN60598-2-22 standard update content
Definition
Add the definition of practical emergency light source luminous flux (PELSF): the minimum luminous flux of the light source observed within the rated duration of the emergency mode.
Optical test requirements
1. The manufacturer shall provide the intensity distribution data required to calculate the emergency lighting device according to ISO 30061. The light intensity of the emergency mode can be expressed in cd or cd/1000lm. If it is expressed in cd, the manufacturer needs to provide the rated luminous flux derived from the light distribution curve table at the same time.
2. If the value is expressed in cd/1000 lm, the manufacturer should provide the reference luminous flux for emergency mode.
For lamps with tubular fluorescent lamps or other discharge lamps, the reference luminous flux is the actual emergency light source luminous flux PELF, multiplied by the EBLF of the relevant emergency ballast.
For lamps with LED light sources, the reference luminous flux is: actual emergency light source luminous flux PELSF, this value can be calculated as follows: LED module (LDL) under the reference conditions corresponding to the lamp (under the same TP) and rated current (normal Mode) multiply the luminous flux of the light source by the EOFI (emergency/abnormal mode) of the relevant emergency control device.
3. The emergency luminaire shall provide at least 50% of the luminosity data in the emergency mode declared by the manufacturer for 5 seconds after the normal power supply failure; and after 60 seconds, until the end of the rated duration of emergency operation, it shall provide 100% of the rated luminosity performance.
Emergency luminaires used for lighting in high-risk mission areas should provide 100% of the declared luminosity data within 0.5 seconds after the normal power supply failure, and continue until the end of the rated duration of the emergency operation.
