.NET Framework Class Library
Light Class

Model3D object that represents lighting applied to a 3-D scene.

Namespace:  System.Windows.Media.Media3D
Assembly:  PresentationCore (in PresentationCore.dll)
Syntax
Visual Basic (Declaration) 
Public MustInherit Class Light _
    Inherits Model3D
Visual Basic (Usage) 
Dim instance As Light
C# 
public abstract class Light : Model3D
Visual C++ 
public ref class Light abstract : public Model3D
JScript 
public abstract class Light extends Model3D
XAML 
This class is abstract; see Inheritance Hierarchy for derived non-abstract classes usable in XAML.
Remarks

Because lights are models themselves, you can apply transformations and animations to them, just as with other models.
Examples

The following excerpts show examples of two Light types, DirectionalLight and AmbientLight.
