During the development phase the lighting
properties of all explosion-protected light fittings
are tested in the CEAG lighting laboratory.
In this way it is ensured that the reflectors,

succeeded in optimizing
both the illumination
of surfaces with
the largest possible light distribution and the
illumination of objects with the highest possible
axial light intensity. The polar curve of
each light fitting can be found in the technical
data and can be used together with the
other lighting values to calculate the illuminance.
INL-WIN CEAG, the design software
INL-WIN CEAG is a lighting calculation program
for the design of lighting requirements.
This program can be used with WINDOWSTM and is an excellent menu-driven aid for the
everyday work involved in the design and engineering
of explosion-protected lighting
equipment.
The lighting data of the CEAG light fittings is
stored in a data base and is used for the
light calculation. By entering a few details,
such as the height, width and length of the
room, the reflectance of the walls and the
desired illuminance, it is possible to make an
exact calculation of the number and distribu-
tion of the explosion-protected light fittings.
This simple, yet optimal calculation makes it
possible to minimize the number of light fittings
required.
If emergency lighting is required, the program
shows the exact number and positions of the
light fittings. Individual, customized lighting
arrangements can also be realized with this
program.
Electronic ballasts (EVG)
Nowadays it is not possible to imagine modern
light fittings for fluorescent lamps without
the EVG technology. Features such as
immediate starting, the absence of flickering
during operation or the minimal heat
rise are only possible with this technology.
With the EVG technology, fluorescent light
fittings for use in hazardous areas also provide
decisive advantages:
- possibility of a lamp-sparing cold start
- use of bi-pin lamps, Ø 26 mm
- use with various mains voltages
- regulation of lamp current with fluctuating
mains voltages
- safe lamp ignition at low and high ambient
temperatures
- service life of lamp is approx. 12.000
hours
- AC/DC operation possible
With the latest generation EVG 97, CEAG
provides a safe and reliable operation of
the explosion-protected eLLK 92 and the
eLLB 20 light fittings.
A possible hazard due to the so-called
”End of Life“-effect is according to experts
not very probable, so that no special maintanance
procedures are neccssary.
