Human Centric Lighting (HCL)

The following functions must be enabled in the settings under "HCL".

Up to 24 interpolation points are possible per day. Fixed times can be entered and in addition the calculated sunrise and sunset can be referred to for the color temperature adjustment. All interpolation points are driven to linearly in relation to the steps. The color temperature can be fixed via manual operation by means of a slider. The color temperature applies to all lamps (broadcast).

The times for this are calculated on the basis of the date and the specified longitudes and latitudes (see Settings). The currently set process, the current time and the calculated sun values are illustrated in the diagram.

With regard to the possible times for sunrise and sunset, try to enter season-independent values if possible in order to avoid ups and downs of the color temperature.

After closing the dialog box, the table sorts itself in chronological order.

The dimming position changes the output value of a group proportionately – provided it has "HCL dimming position" enabled. In the Fixed Control mode the set value is influenced and in the Daylight Control mode the setpoint is changed accordingly.

According to current studies, TunableWhite only becomes genuine Human Centric Lighting through the dimming position. The desired HCL effect is only made possible by the color temperature and the matching luminous intensity.

 

Human Centric Lighting (HCL) 1:

 

Time

End time when the color value should be reached. This is at the same time the start point for the next interpolation point.

Color value

2700 .. 6500 Kelvin

Dimming position

Reduces/increases the set value/setpoint of all groups. Provided "HCL dimming position" is enabled for each group.

Sunrise

Displays the currently calculated sunrise. The selection may only be made and activated once.

Sunset

Displays the currently calculated sunset. The selection may only be made and activated once.

Drive time

Determines the drive time (after sunrise/before sunset) to the desired color temperature. Can be used to artificially prolong the effect.

Enable

Enables the interpolation point. Disabled interpolation points are ignored and are invisible in the display.
