Curve
The dimming curve, commonly called curve, is the correlation between the change in the
value of the dimming control signal and the actual change in the fixture's brightness. Curve
is also the extent to which the fixture lags in its response time to the control signal in order
to facilitate smoothness in dimming.
Standard
Standard is a modest curve for intuitive brightness changes at both high and low ends of
the dimming range. Moderate lag in response for good smoothness. It allows quick jumps
in brightness. Suitable for most applications.
Incandescent
Exaggerated curve mimics the response of tungsten on a conventional dimmer. Lag is quite
pronounced and present even in full on or off bumps. Extreme smoothness with no instant
changes. Best when fixtures must operate in sync with incandescent sources.
N o t e :
All Output settings, if the fixture gets too warm and internal components approach
unsafe operating temperatures, the total power to the LED array is gradually reduced
and proportionate brightness levels between the various colors of LEDs are
maintained as much as possible in order to preserve the overall color mix; however,
some minor shifts in output may occur. Power continues to ramp down as much as
necessary until internal fixture components return to a safe temperature. The fixture
displays a warning message on the home screen indicating that power budgeting is
in place, showing the percent of total power that is currently used.
If the fixture exceeds its maximum internal temperature, the fixture enters a cool-
down state, stops responding to the control signal, and it shuts down most or all
power to the LED array and displays its over-temperature status according to its
setting for over-temperature warning.
