A decorative lighting device that projects a gobo. Components from right to left are the lamp house, the gobo itself (in this case a grid made of wires), and the focusing lens. In a theatrical unit, all three would be in an enclosure to prevent light spillage. The insert at lower right shows the pattern this device projects.

Many "old-school" grips would say that any unnatural pattern used to create a shadow is a cookie. [citation needed] Cucolorises are sometimes thought of as a subset of the gobo category. Cucolorises differ from standard gobos in that they are used farther away from the lighting instrument, and therefore do not need to be as heat resistant.
By placing the pattern inside of the focal plane of a fixture adjustments to image (hard or soft edges) can easily be created. Larger pattern holders are also available designed to mount into the accessory slot on some fixtures, allowing for the use of larger gobos, or the projection of two overlapping patterns from a single fixture.
A light characteristic is all of the properties that make a particular somewhat navigational light identifiable. Graphical and textual descriptions of navigational light sequences and colours are displayed on nautical charts and in Light Lists with the chart symbol for a lighthouse, lightvessel, buoy or sea mark with a light on it. Different ...
Gobo (lighting), a template or pattern that controls the shape of the light from a projector or spotlight. Gobo (recording), a movable acoustic isolation panel; Gobo Fraggle, a character in the television series Fraggle Rock; GoboLinux, a Linux distribution; Gobo, a character in Bambi, a Life in the Woods
Lighting instruments (generally ellipsoidals) may also be used to project scenic effects on cycs and scrims, by using gobos, also known as templates or patterns. With an ellipsoidal reflector, the light source is positioned at one focal point of the three-dimensional ellipse, then the pattern - cut metal or glass or other heat-resistant ...
The pattern of light an instrument makes is largely determined by three factors. The first are the specifics of the lamp, reflector and lens assembly. Different mounting positions for the lamp (axial, base up, base down), different sizes and shapes of reflector and the nature of the lens (or lenses) being used can all affect the pattern of light.
