Spot Lamp Tab
A spotlight emits light in a cone shape around the direction in which the fixture is pointed.
- Beam Angle
- This angle defines how wide the main, bright beam of light will be.
- See: Beam and Field Angles
- Field Angle
- This angle defines a cone of softer light outside the main beam.
- (Use 0 for the default of 180 degrees, unless you want a really tight light)
- Lamp Length -
- This is the length of the cone-shaped light source that will be visible in the rendering.
- Beam Length -
- This is the length of the semi-transparent aiming cone that is visible in SketchUp but not in the rendering, which makes the light fixture easier to aim and manipulate in SketchUp.
- Set this to 0 if you don't want to create a beam aiming cone.
- Glue to surfaces -
- If Glue to surfaces is checked, as the light fixture is placed in Sketchup it will automatically stick to the nearest surface and point itself away from that surface.
- Show Beam in SketchUp
- If checked, then the RPS Light Beam layer in SketchUp will be turned on
- Show Beam when rendering
- If checked, then the lamp beam is included in the rendering.
- This is one way to render visible light beams
- See: Visible Light Paths
- Make the bulb invisible when Rendering
- If checked, then the bulb itself will be invisible when rendering.
Common Settings
- Length, Width, or Diameter sets the size of the light.
- Settings, at the bottom of the dialog, are common to all types of light fixtures.
- Intensity
- The brightness of the lamp. Intensity can be specified in either Watts or Lumens. (A 100 watt incandescent lamp emits about 1700 lumens).
- (IRender uses the conversion factor of 100 watts --> 1700 lumens for all lamps.)
- Color
- Click this button to bring up a color picker dialog and change the color of light emitted by the light fixture.
- Component Placement Mode
- Single - place just one light fixture and then stop
- 'Multiple - place the same light fixture repeatedly until you activate a different SketchUp tool.
- Lighting Channel
- Lights are normally placed in a default Channel - 3 for ceiling Lights or 2 for other lights.
- Set the channel to a number from 1-7 to create a light and place it in a particular channel.
- See: Lighting Channels
- Create Lamp
- Press Create Lamp when you are ready to begin create the lamp component.
