A logo gobo, also known as a custom gobo, is a lighting accessory that is used in theatrical, architectural, and event lighting to project a specific image or design. Gobo is short for "go between" or "goes before optics", and refers to a thin metal or glass plate with a specific design or pattern that is placed in front of a light source to project that image onto a surface.

A logo gobo is created by etching a design or logo onto a thin metal or glass plate, which is then inserted into a lighting fixture, such as a profile spotlight or an ellipsoidal reflector spotlight, to project the image onto a surface. The projected image can be used to highlight a company logo, brand name, or other specific design element as part of an event, exhibition, or architectural lighting display.

Logo gobos are commonly used in a variety of settings, including corporate events, trade shows, weddings, concerts, and theater productions. They are a versatile lighting tool that can be used to create a variety of effects, from projecting a simple logo onto a wall, to creating a dynamic pattern or texture that moves across a surface.

Overall, logo gobos are an effective way to add visual interest and branding to a lighting design, and can help create a memorable and impactful event or display.
