Projector Light Effects

Save

Projectors have progressed a long way from simple silhouette and still slide projectors. With the advent of digital projectors, users do not need to use slide pictures or film reel. Video can be stored digitally and streamed directly through the projector onto another surface. This allows advanced effects to be used that were too complicated for an analog projector to handle. The effects that can be created vary depending on the projector, the software used to create the effects and the surface to which it is being projected.

Rippling Lights

  • Rippling lights that move gracefully across the wall can be projected using a modern projector. The lights move in a set pattern to mimic many other effects such as fire and water. The user can select the colors to be used in displaying the effect and also the speed with which the light will ripple. The projector manages to create the effect by projecting light through two offset glass plates. These plates revolve at various speeds, giving the effect that the light is rippling across the surface on which it is being projected.

Walk on Water

  • Using projectors and special effects, it is possible to create a realistic pool of water on almost any surface. The projector can be used to project a large body of light onto the ground, upon which users may walk, giving the illusion that they are walking on water. The projector creates a pattern of white light, then projects ripples over this pattern to create an aquatic feel. Blue and green light can be added to create a more oceanic feel. The water effect can be projected onto a wall to create a window into an aquatic scene.

Running Directions

  • Rather than having static signposts, a projector can be used to project eye-catching directions. Running arrows, notices and even instructions can be projected onto the floor or walls to guide visitors to their destination. Some projectors are capable of moving, projecting the directions as though they are moving. Arrows can move ahead of walkers, guiding them along a pre-programmed path, telling them when to turn or stop.

Star Projector

  • Used for both enjoyment and education, star projectors can create the simulation of celestial bodies. Many projectors, such as the Laser Star Shower Projector by Edmund Scientific, do not create exact replicas of stars but merely create the illusion of stars passing overhead. With advanced programming skills, though, a user could make the projector project exact constellations onto a surface, which could then be used to teach astronomy.
