❚❘❘
In all cases, the Luminaire Properties dialog appears.
If you are working in a Lightscape Preparation stage,
the luminaire is placed in Isolate mode.
2. Do any of the following:
•
Set the source type
• Position the source in relationship to the luminaire
geometry
• Set the lamp color
• Set the intensity magnitude
• Set the intensity distribution.
3. Click OK or Apply to update the luminaire prop-
erties for the selected luminaire.
Specifying Source Types
The source type defines the general lighting character-
istics of a luminaire. Three types of light sources are
supported: point, linear, and area. By default, all newly
created luminaires are assigned a point source type.
Note: Source types are exclusive to luminaire defi-
nitions. They cannot be specified for single
instances of luminaires. You save source types only
in the Preparation stage.
Point Source
A point light source distributes energy from a single
point. An incandescent bulb and a halogen spotlight
are good examples of point sources.
Linear Source
A linear light source distributes energy along a
straight line segment. A single fluorescent tube is a
good example of a linear light source.
Area Source
An area light source distributes energy from a triangle
or convex quadrilateral surface. A typical area light is
a 2’ x 4’ fluorescent fixture that emits light evenly over
the entire surface of a diffuser panel.
