Human Centric Light (HCL)

This invisible component is used for daylight simulation. This can also be used to set the corresponding color temperature for the course of the day.

 

Data points of the component

Name

Type

Function

Active Time [min]

Bidirectional

In "Free Period Selection" mode, the set active time is output here or can be adjusted here during runtime.

Current Position [s]

Bidirectional

Above this, in "Free period selection" mode, the output of the current simulation position within the period is displayed in seconds. Furthermore, the position can also be set manually to jump to a certain position within the period and continue from there.

Current State

Output

Output of the simulation status (0 = STOP, 1 = RUN, 2 = PAUSE)

Presence

Input

Via this data point, the component can be informed whether persons are present. If the presence evaluation is active, the outputs will be deactivated in case of absence (light switched off).

Use presence input

Bidirectional

This is used to output / set whether the presence is evaluated or not.

Debug [Text]

Output

Attention: Diagnostics or debug outputs are only intended for the case of an error. Please use only after consultation with the support team! These may significantly affect the performance of the service when used.

Data point for displaying / setting the endless repeat.

color temperature [K]

Output

Currently calculated color temperature

Manual color temperature [K]

Bidirectional

Value of the color temperature, which is set, if over the data point "Manual" a true is received (causes a temporary overwriting of the computed color temperature).

Manual brightness [%]

Bidirectional

Value of the brightness that is set when a true is received via the "Hand value" data point (causes a temporary overwriting of the calculated brightness).

Manual brightness [0-255]

Bidirectional

Value of the brightness that is set when a true is received via the "Manual value" data point (causes the calculated brightness to be temporarily overwritten).

Set Manual Value

Bidirectional

Input to call the defined manual value manually (true) or delete it (false -> return to the current or last simulation value)

brightness (calculated)

Output

Calculated brightness value as a comma value

brightness (compensated)

Output

Brightness, compensated for current brightness with constant light control in%

brightness (regulated)

Output

Calculated brightness (incorporation of the lumen package and the correction factor), compensated for the current brightness with constant light control

brightness [%]

Output

Returns the current brightness in %.

brightness [0-255]

Output

Returns the current brightness in a range of 0-255.

Within active range

Output

Here you can see if the simulation is currently in the "active range of the curve" or not.

Constant Light Regulation

Bidirectional

This can be used to set whether the currently measured ambient light should be taken into account when calculating the dimmer values.

Meassured Light

Input

Input of measured light for constant light control

Lux Correction

Bidirectional

This factor is taken into account when calculating the value "brightness calculated".

Pause

Input

Start time (24h mode)

Bidirectional

Dynamic entry of the start time for the 24 hour mode. This represents the sunrise and can be taken over by the astro timer.

Stop

Input

Bidirectional

Driver on or off.

Type

Bidirectional

Data point for displaying / setting the progression type (0 = daylight, 1 = activate)

Mode

FreePeriod...

Setting for 24h mode or own period time, as well as endless repetition

Max colour temperature [K]

6500

Maximum value of the colour temperature in Kelvin for light source 1 (mixture with light source 2)

Min colour temperature [K]

3000

Minimum value of the colour temperature in Kelvin for light source 2 (mixture with light source 1)

Max brightness [%]

100

Maximum brightness in per cent

Min brightness [%]

40

Minimum brightness in per cent

Manual value Colour temperature [K]

4000

Manually set value of the colour temperature in Kelvin. This value is assumed if a true is received at the manual value data point.

Manual value brightness [%]

100

Manually set brightness value in per cent. This value is assumed if a true is received at the Manual value data point.

Type

Daylight curve

Type of colour temperature/brightness curve. There are currently 3 profiles available: Daylight curve, Activate curve and Manual curve (see below).

Manual curve

 

This option can be used to set your own curves for colour temperature and brightness.

Update interval [s]

30

Setting the intervals for updating the calculated colour temperature/brightness values.

Pause mode

Hold position

This can be used to set whether the simulation of the curve progressions should be continued or paused in the background during a pause (or during overwriting using a manual value).

Constant light control

 

This can be used to set whether the currently measured ambient light should be taken into account when calculating the dimming values. The current brightness of the curve is offset against the brightness actually measured by the sensor. The calculated value is output at the "Brightness (regulated)" data point.

External constant light control

 

If activated, the dimming values at the outputs are compensated according to the setpoint value of the external control.

Lumen package

1

The maximum brightness of the lamps used can be entered here. This value is multiplied by the calculated target brightness (in %) and the correction factor and output on the data point (brightness calculated).

Light correction factor

1

This factor is taken into account when calculating the "Brightness calculated" value.

Evaluate presence

 

If this option is set, presence evaluation is active

Upper threshold value for 0% hysteresis

5

If the brightness was at 0%, it must rise above this value before it is output again.

Autostart

 

This can be used to set whether the sequence should start automatically when the component is active.

Driver on/off

 

This can be used to set whether the component should be active when the system is started.

 

Below are the progressions of the brightness and color temperature of the two modes. The following values are set:

Color temperature = 3000K - 6500K;

Brightness = 40% - 100%;

Period: 2 minutes;

Active time: 1 minute;

Repeat: Active

 

Course of the brightness in the mode "daylight" (runs within the defined "active time" between color temperature min and color temperature max):

k1

 

 

Color temperature trend in "daylight" mode (runs within the defined "active time" between color temperature min and color temperature max):

k2

 

 

Color temperature trend in "Activate" mode (runs within the defined "Active time" between color temperature min and color temperature max):

k3

 

k4

 

Example:

Time lapse with a period of 2 minutes and an active time of 1 minute (continuous repetition), Type: Activate.
