Individual EB for One Illuminant
By using electronic ballasts (EBs) for direct and alternating voltage for one
illuminant, mains and emergency power can be supplied via the same
circuit. No separate circuit is therefore needed for single-light luminaires.
Emergency and standard lighting are ensured through the same
illuminants. Switching takes place on site. Likewise both direct and
alternating voltage can be used.
Emergency Lighting Assembly with 3h Battery Set
An emergency lighting assembly with an individual battery is used for
networks without a central emergency power supply. In this case switching
from mains to emergency power is done through a monitoring chip
integrated in the emergency lighting assembly.
The lamp can be operated in standby or permanent connection mode.
If light switches are installed for mains operation in the permanent
connection mode, an additional wire is needed in the supply line with a
permanent phase for network monitoring and as battery charging voltage.
The price for a necessary individual EB is not included in the emergency
lighting assembly. Emergency lighting chips with an individual battery
must be checked for correct functioning at regular intervals. In this case
an LED showing the status of the emergency lighting chip can reduce the
expense of a check. PERFORMANCE IN LIGHTING supplies LEDs for status display
as accessories. These are normally delivered loose to be installed by the
client, but can also be pre-installed in the luminaire on request. There may
be various positions to choose from for installing the LED. If you have any
questions on this please contact the member of staff responsible for you in
the sales department.
PERFORMANCE IN LIGHTING supplies the luminaires for emergency lighting
in three designs as required:
Emergency Light Version E14
Switching from mains to emergency power and monitoring of the
connected luminaires is on-site. They can be optionally operated with
direct or alternating voltage.
For safety reasons emergency lighting according to DIN 5035 takes over
the necessary lighting of rooms when there is a power cut. A distinction
is made between safety lighting according to DIN EN 50172 and substi-
tute lighting. Depending on building type, the emergency lighting must
take over the artificial lighting within 0.5 to 15 seconds with a minimum
required illumination strength. See also adjoining table on this. The stipu-
lated illumination strengths are minimum requirements and must also be
guaranteed at the end of the nominal operation period.
This can be done through a central emergency power supply such as
central or group batteries for direct voltage supply or a power generator
for alternating voltage. The advantage in this is easy central function moni-
toring for equipment and connected luminaires. Alternatively, emergency
lighting can be guaranteed with individual batteries, which requires a
considerably lower installation expense and furthermore makes an easy
distribution over various phases and electrical circuits possible. Here too
central function monitoring for equipment and connected luminaires is
possible. It should be noted here that the relatively low installation expense
of individual battery systems contrasts with a considerably higher battery
maintenance expense. The following table shows the requirements for
safety lighting according to DIN EN 50172, Part 1.

*Only for all escape routes outside assembly rooms, stages and performance areas.
In the aforementioned spaces which are darkened during normal operation, doors, aisles and steps at
least must be discernible through safety lighting in permanent connection (PC).
In planning and designing lighting installations for emergency lighting, a light loss factor of generally
0.8 must be taken into account due to ageing and staining of the luminaires.
The values required in the table must then be fulfilled at the most unfavourable point, with a
uniformity of at least 1:40 being required.
Measurements for this are made in the middle of the escape route at a height of 0.2 m.
