Emergency Lighting
Design Guide
The application of emergency lighting
This design guide will help you to plan and implement
an emergency lighting installation that satisfies all the
legal requirements and ensures safe evacuation in the
event an emergency.
What is emergency
lighting?
Emergency lighting operates
automatically when a lighting
circuit loses the mains
power supply.
Emergency lighting falls into
two categories:
Specific requirements for
emergency lighting are set out in

Performance, Efficiency,

All Thorn products are designed
to adhere to three core values:
performance, efficiency
and comfort. This is the PEC
programme, which delivers quality
in a lighting installation.

converted versions of standard
fittings for use in emergency
lighting schemes.
As a pioneer in the field of
emergency lighting, Thorn has
developed three different ways of

include one or more of the
following:

moving machinery or vehicles.
Example: an industrial lathe

What are the regulations

The regulations governing high

down in the lighting standard
EN1838. This states that
emergency lighting must meet the

ÃՈÌ>LiÊvœÀʅˆ}…ÊÀˆÃŽÊÌ>ÎÊ>Ài>ð
For example, in a workshop

If other lamp types are used

ensure that output and activation

ˆ“ˆÌʜvÊä°xÊÃiVœ˜`ð
In this case, to meet the
regulations, luminaires may need
to have more than one lamp that

These stringent requirements
mean that tungsten halogen
solutions are often used in these
applications. However, Thorn has
developed special emergency
“œ`ՏiÃÊ̅>ÌÊi˜>LiÊvˆÌ̈˜}Ã
with fluorescent lamps to meet
these regulations.
The lamp is lit again in less than
ä°ÓxÊÃiVœ˜`Ã]ÊVœ“«>Ài`Ê܈Ì
a typical 2 second restrike for a
standard emergency luminaire.
This solution is particularly
useful in applications such as
cleanrooms and kitchens, which
require fewer surfaces where
dust or particles may gather and
higher emergency light levels to
manage the safe shutdown
of equipment.
In a maintained fitting, when the
lamp is already lit, this module

the fittings into the emergency
