Dimmer shutter
JALOUSIE2 enables to control the light intensity of discharge fresnel luminaires by a
mechanical system. The rotating blades in front of the lighting unit stop an increasing among
of light coming from the lamp.
When JALOUSIE2 is powered up, motor reset procedure is done.
The position of the blade goes from 0% (blades closed
– no light output) to 100% (blades
open
– maximum light output).
Control of the aperture can be done locally through the display and optional potentiometer or
remotely by using USITT DMX 512 protocol. Choice of LTP or HTP merger is possible in
setup menu.
Dimming curves can be selected in setup menu:
o
LM: Linear Motor
o
LL: Linear Light
Mounting a mechanical shutter on a spotlight will affect the apparent output of the
luminaire so it is strongly recommended that all precautions be taken during the design
of the light plot. ROBERT JULIAT shall not be responsible for reduced lighting levels
and aperture that may result from the use of a JALOUSIE2 shutters.
