Emergency Lighting Testing and Certification

With the development of LED technology, emergency functions have become one of the features of LED lighting products.

An emergency light is a battery-powered lighting device that automatically turns on in the event of a building power outage. Emergency lighting is a standard requirement for most building codes in new commercial and residential buildings as well as older buildings.

LED Emergency Lighting  

LED products offer bulb life advantages and energy savings to meet virtually all photometric parameters.

LEDs also help develop a new generation of more compact emergency luminaires while maintaining or improving the quality and distribution of light - a major advantage for architects and designers.

In addition to lamp life advantages and energy savings benefits, LED emergency luminaires gain further advantages in terms of lamp replacement costs, illumination of high-risk task areas using controlled light distribution, heat reduction, light quality and lamp source quality.  

Emergency Lighting Standards 

UL 924 Safety Standard - Emergency Lighting and Power Equipment

This scope applies to equipment used in unclassified locations and intended for connection to branch circuits of 600 volts or less. Such equipment is intended to automatically provide lighting or power, or both, to critical areas and equipment in the event of a failure of the normal power supply, in accordance with the National Electrical Code, NFPA 70, Life Safety Code, Article 700 or 701 of NFPA 101, Fire Code, NFPA 1, International Building Code, IBC and International Fire Code, IFC.

Examples of equipment include: 

Exit signs

Emergency luminaires

Unit equipment

Central station battery packs

Inverters

Automatic battery charging and control equipment

Automatic load control relays

Disturbance signaling equipment

IEC 60598-2-22 Special requirements - Emergency lighting luminaires

This scope specifies the requirements for emergency luminaires for use with electric lamps on emergency power supplies not exceeding 1000 V and does not include the effect of non-emergency voltage reduction on luminaires equipped with high voltage discharge lamps.

Example:

 ►Emergency lighting

For use in case of failure of the normal lighting supply

►Emergency escape lighting

For lighting for the safety of persons leaving the area or attempting to terminate a hazardous process before leaving the area

►Standby lighting

Enables normal activities to continue essentially unchanged

►High-risk work area lighting

Ensure the safety of personnel involved in potentially hazardous processes or situations and enable appropriate shutdown procedures to ensure the safety of operators and occupants of the premises
