Introduction

The primary purpose of emergency lighting is to provide relief in clear (smoke-free) and smoky conditions when normal power/lighting fails

Visual conditions that panic and promote safer evacuation of people within a building.

The design of the emergency lighting solution is based on the worst conditions of the lamp during its service life (such as minimum light output, maximum glare limit), and only based on

Due to the direct light coming from the luminaire, the contribution of mutual reflections from the room surfaces is negligible. However, indirect luminaires or uplights (in continuous/combined

mode), the fixture works together with the reflective surface, and the first reflection is treated as direct light to the system, and subsequent reflected light is ignored.

The requirements given in this document are minimum required values for design purposes and are for the full rated duration and design of the equipment.

Calculated at the end of life. This document also has a dedicated chapter on smoke.
