What is aGobo? A “Gobo” is a small stencilled circular disc, and found in lighting to create a projected image or pattern. The phrase Gobo is short for “Go Between Optics”, describing the location where it needs to be positioned in the light path of a gobo light. Whilst Gobo’s are not a new technology these are still being utilized on events around the world. In today’s event market they have taken on a far more creative role as technology advances enable more in depth and impressive shapes to be created.
Gobo’s are available in two main types; steel and glass. Steel gobos are extremely basic, usually have a quick lifespan and therefore are typically described as “black and white”. Glass gobo’s are definitely more detailed, usually have a long lifespan and they are typically identified as “coloured”. There is an emerging third kind of Gobo, that is designed especially for LED fixtures, and is made from plastic.
Gobo’s come in various diameters, ranging from approx 20mm to approx 150mm. The diameter of a gobo is dictated from the fixture, so it is very important to make sure you know what fixture the gobo needs to be used in before manufacture. If used in a static fixture, the projected image will likely be stationary, if however installed in an intelligent fixture the image may be moved anywhere across the event space.
What events are Gobo’s applied to? Events such as gala dinners, product launches, award ceremonies use gobo’s to back up the event branding and also to provide visual interest. A developing trend in weddings is always to to make use of ornate glass Gobo’s featuring the bride and grooms name or initials which can be presented as a keep sake through the event.
What exactly is needed for a customised Gobo? A couple of specific products are required for a highly effective gobo display:
Profile Fixture: a profile light which is designed to have a gobo in the gobo light projector is needed to focus and zoom the gobo.
Gobo Holder: a particular accessory that supports the gobo set up is required for insertion into the profile light.
Projection Surface: a devoted surface like a wall or drape upon which the gobo is projected upon is needed.
A Gobo is a physical template, most frequently on steel or glass, which is placed before an easy source to change the shape from the light onto a surface. Deriving its name from “Go Between” or “Goes Before Optics”, this part of metal or glass is used to bar areas of the lighting source. Bat-signal_1989_filmCustom gobos permit you to display words, logos, shapes, and patterns on a wall, floor, ceiling, or any other large flat space in your venue. These are usually used before a static light source rxziif as a leko and they are placed in a gobo holder to carry the gobo set up in the light.
A good demonstration of this sort of light projection is definitely the bat-signal shown inside the Batman films and comic books. The bat-signal includes a circular light shining within the sky having an opaque Batman logo preventing light from shining through it, resulting in a circular light inside the sky with the Batman logo cut out of it.
Why would you use a gobo? A gobo light is an excellent option to banners and signage on corporate events, providing something visually different for the audience to soak up. They can also be used to create patterns, imagery and shapes to support the event theme. Check out some images below of gobo’s of shapes and sizes.
