The Light source properties window is a tool to adjust the individual light settings of a light in your plan. This is helpful if you have a large amount of lights featured, and need to lower the light intensity for rendering.
- The properties can be accessed via the light's Object parameters by double-clicking on the light in Furnishing mode:
In the Parameters section, you can select Light source to be set to On or Off.
Setting the source to Off is helpful if you want the object in the room, but to have no affect on the lighting you have set up.
Setting the Light source to On will allow you to alter the Light source properties. To access, click the Light Setting button near the top of the window. - The properties are also accessed from Define light profiles in the Real-time and photo-realistic light settings section. In this option it will affect the lighting for all wall units or the insides of glass cabinets. See article Define light profiles for more information.
Light source properties
The window has three sections:
Light type
Intensity
Light colour
Light type
This section shows whether the object/ light source has been defined as Pointlight, Spotlight, LED strip or geometric. It also allows use of IES profiles.
- Use IES
IES Profiles are an industry standard method of diagramming the brightness and falloff of light.
Tick on the Use IES box to use an IES Profile.
Press Select... to open the IESProfiles file and select a profile:
See article What are IES-profiles? for more information. - Pointlight - This is highlighted if the object/ light source is defined as a point light. The light object cannot be altered.
- Spotlight - This field is highlighted if the object/light source is defined as a spotlight. The light object cannot be altered.
A spotlight will be in the form of a cone. This means that the light will end on a surface as a circle.
The concentration and sharpness of this light cone can be set by specifying the angle of the inner and outer circle, where the inner angle represents a stronger light than the outer, and the difference between the inner and the outer angle will therefore be affected by the sharpness of the light. - Hard light angle (A)
In this field you specify the angle of the innermost part of the light, i.e. that part of the circle with the hardest light intensity:
- Soft light angle (B)
In this field you specify the angle of the outermost part of the light, i.e. the part of the circle with the softest light intensity.
The value in the Soft light angle field must therefore be greater than the value in the Hard light angle field.
Intensity
In this group box you can adjust the intensity for the relevant light source.
- Use the slider to adjust the intensity from Off to Maximum.
- The default Lumen value will be in the Max strength: box. Change the value to adjust the intensity further.
Light colour
If all light sources are completely white, it may result in a sterile look. If you change the colour properties of the light sources you can give the plan a warmer, more natural look.
- Lamp type
Use the drop down to select lamp type. Each lamp type has a specific colour temperature. If you for instance change the lamp type to Halogen the colour temperature will be changed to 3100 Kelvin. - Colour temperature
The colour temperature (measured in Kelvins) is a common way of describing the warmness of a light. Typically fluorescent light and LEDs are perceived as cold (with a high colour temperature) and halogen (turned down) and candles are perceived as warm (with low colour temperatures). Use the slider to adjust. - Colour value
Click on the Select button and Winner Design will open the Select a colour window and you can change the colour value. After selecting the preview will show in the box.
