Light source size parameters
Light source objects have axes that allow you to align and lock them to
the fixture geometry or to a reference plane. If you place the light source
inside solid geometry, you receive a warning that no light will be emitted
when the family is in a rendered view. The light source can be located on
the face of your fixture geometry, or it can be located within a void inside
the geometry for a more realistic representation of the fixture.
Figure 20.15
shows a downlight family with a light source located inside the geometry of
the fixture. The light distribution that appears to pass through the sides of
the fixture will be blocked by the solid geometry when shown in a rendering.
A material can be applied to the geometry to affect how the light will be
reflected inside the fixture.
