Extension to the DALI program<br />
Emanon Goborotator<br />
Through the use of independently<br />
controllable rotating gobos or<br />
fresnel lenses, the projection<br />
effects created can be fascinating.<br />
The character of these projections<br />
can range from slow moving,<br />
subtly atmospheric effects to<br />
stimulating, highly dynamic focal<br />
points. Controlling the direction<br />
and speed of rotation is particularly<br />
user-friendly with the Light<br />
System DALI and its integrated<br />
Light Studio software, which provides<br />
a tool especially for the<br />
operation of the Goborotator.<br />
The Light<br />
Studio software<br />
includes a tool<br />
to control all<br />
the Goborotator<br />
functions via<br />
Light System<br />
DALI.<br />
Master dimming action<br />
The master dimming function<br />
is used to increase or decrease<br />
the overall brightness of a zone<br />
using push-buttons or the Light<br />
Changer. To master special lighting<br />
tasks and take account of<br />
differences in the dimming function<br />
of the lamps, the master dimming<br />
action of each Light Client<br />
can now be controlled individually.<br />
The Light Book module of the<br />
Light Studio software provides<br />
the relevant tool.<br />
Dimmable Light Clients with<br />
LEDs, low-voltage halogen lamps<br />
or fluorescent lamps, for example,<br />
provide a choice of linear<br />
function and operation that prevents<br />
the Light Client from falling<br />
below a pre-defined limit or<br />
switches it off. Switchable Light<br />
Clients (DALI switching actuators,<br />
HIT luminaires) can be given<br />
individual switching thresholds.<br />

As an additional<br />
feature, each Light<br />
Client can now,<br />
depending on its<br />
dimming features,<br />
be defined individually<br />
in relation<br />
to the master<br />
dimmer.<br />

During master<br />
dimming, a<br />
dimmable Light<br />
Client normally<br />
follows a linear<br />
dimming curve.<br />
Even so, dimmable<br />
Light Clients<br />
can also have<br />
a limit below<br />
which they can-<br />
not fall when<br />
master dimming<br />
is used.<br />
As a default, the<br />
threshold level<br />
for switchable<br />
DALI Light Clients<br />
ranges between 0<br />
and 1%. Depend-<br />
ing on the light<br />
scene requirements,<br />
this<br />
threshold can<br />
now also be set<br />
individually.<br />
