With ReluxDesktop, it is possible to individually dim luminaires that have been placed in a scene. In other words, both the RGB colour value of a luminaire and its luminous flux can be adjusted. For luminaires with a separate white component, so-called RGBW luminaires, it is possible to adjust this component too. The dimming values are evaluated in all the calculation modes available in ReluxDesktop.
To ensure that the dimming function is available, it is necessary to go to the product selection and then the "Modify luminaire" dialogue and check that the "Dimming" option is activated for the luminaire type in question. This setting is activated by default.
Please note: It is always the case that, if dimming is activated at the same time as a lamp colour that differs from the colour white, the initial luminous flux of a luminaire placed in the scene will always be reduced. If the luminous flux is not to be reduced with an activated lamp colour, it is necessary to deactivate the "Dimming" option.
Luminaire type with activated dimming option.
As soon as the "Dimming" option is activated for a luminaire type, an additional "Dimming" tab appears in the property window of the positioned luminaires. In this tab, it is possible to set the RGB value and also the luminous flux via controllers as well as directly via input boxes. Colour values can also be adopted directly from a colour selection dialogue for the luminaire colour, or a dimming value already used in the scene can be allocated. Colour and dimming values can also be allocated via the "Pick colour…" and "Pick dimming value" buttons. The current colour value is then shown in a preview. The individual channels can be adjusted in the range [0...1].
All dimming and lamp colour combinations adjustable in the product selector are shown in the following table.
|Combination||Dimming||Lamp colour||Effects on luminous flux and luminance|
|a)||On||On||Luminous flux is reduced depending on chosen lamp colour. Only luminous flux can be further reduced in the dimming dialog while lamp colour is kept unchanged all the time.|
|b)||Off||On||Luminous flux remains unchanged and corresponds to the original value. Calculated luminance views consider the set lamp colour.|
|c)||On||Off||Luminous flux is reduced according to current R|G|B|PHI values in the dimming dialog. Calculated luminance views consider the set RGB value.|
|d)||Off||Off||Luminous flux remains unchanged and corresponds to the original value. Luminance views don’t consider any lamp colour deviating from pure White.|
Tabular overview of all possible dimming and lamp colour combinations

As soon as an RGB or luminous flux value of less than 1 has been set, the luminaire in the scene tree is marked with a controller symbol. This symbol indicates that the luminous flux of the luminaire differs from the original luminous flux.
Luminaire 2 with the controller symbol.
If several luminaires are selected in the scene tree that have different dimming values, this gives rise to a collision of the dimming values involved. In order to resolve this collision, a dialogue appears with various different options for allocating the same dimming value to all the selected luminaires.
With this dialogue, it is possible to allocate a colour value from a colour dialogue or a dimming value that is already available in the scene to all the selected luminaires. By activating the "Apply to selection" button, the value will be applied to all the selected luminaires.

The "Luminaires and room element" output zone sets out an overview of all the luminaires dimmed in the scene. This overview contains relevant information, such as the current luminous flux, the RGB colour value and, if possible, the colour temperature in Kelvin.

After an artificial light calculation with dimmed luminaires, the results overview for the evaluation range in question includes a note to the effect that the total luminous flux has been reduced.
