stamping
Stamping is operated by large, heavy and
sophisticated machinery in a press shop, often
producing high levels of noise, heat, dirt and
even oil. Typical heights in a press shop are 15 to
18 meters, allowing overhead gantry cranes to
move above the presses to transport the heavy
press moulds.
Each press shop has a large workshop of equal
height. In the workshop, a relatively high
illuminance is needed to allow tool repairs to be
performed properly.

Luminaires installed in press shops must be
vibration-proof and made of oil-resistant material
to guarantee worker safety. Tall machinery
( 12 to 15m) causes shadows if luminaires are not
installed according to the layout. Deep light
penetration is needed to obtain the required
illuminance in between and under the metal
presses. To check the press process and to improve
safety, localized lighting must be installed onto the
machines. By arranging the luminaires properly and
by applying narrow beam reflectors, reasonable
uniformity and illuminance levels can be obtained.
Typical lighting installation
The great height in press shops makes the utilization
of high-bay luminaires ideal. If a fluorescent lighting
solution is preferred, extremely narrow-beam
continuous light lines can be utilized. Industrial
high-bay luminaires should be spaced closely to
prevent poor uniformity due to large obstructions.
Although twin mounting of industrial high-bay
luminaires is significantly cheaper than individual
mounting, the latter is preferred to ensure good
light uniformity. Where localized lighting is needed
inside the machinery, the color of the lamps should
be matched to that of the general lighting.
