Understanding Laser Light Show Equipment:
The equipment essential for creating mesmerizing laser show lights can be categorized into various key groups:
Laser Show Lights/Display Systems (Laser Light Show Projectors): These devices are purpose-built to project dynamic, scanned laser beams, aerial laser light effects, and captivating laser light graphics such as text, logos, and animations.
While entry-level laser light "toys" can be found for just a few euros, professional-grade indoor and outdoor laser light projectors are significantly more expensive. It's important to note that the highest price tag doesn't always guarantee the best quality.
Large-scale outdoor laser displays are achieved using powerful laser projectors. These projectors, commonly known as laser beamers, beam bars, or static beams, are primarily designed to emit stationary laser beams, either individually or simultaneously from multiple outputs. While these laser show lights may incorporate additional effects like diffraction gratings to create movement or alter the appearance of the laser beam, they do not belong to the category of laser light show projectors since they do not utilize scanners to generate scanned effects.
What is commonly known as laser show lighting is actually a sophisticated laser display projector or system used by professionals. These laser show lights emit laser beams within the visible spectrum of light and are typically utilized in conjunction with various beam effects.
There is a wide variety of laser show lights available in the market, ranging from those suitable for small private parties, home celebrations, and discotheques to those specifically designed for professional use at concerts, tours, TV shows, and other public events. However, only a few manufacturers produce high-quality laser show light projectors that meet the standards required for professional applications. Despite the progress made by some manufacturers in the Far East through reverse engineering, European manufacturers still maintain an edge in terms of laser beam quality, control systems, scanners, and critical safety features.
Laser display control systems typically come as a package that includes an interface and compatible laser control software. These systems facilitate communication and data exchange between a control computer and the laser show projector. A recent trend in the Laser Display Industry is the integration of the control interface within the laser projector itself, eliminating the need for heavy ILDA cables that would traditionally connect the control interface and the projector.
Hazers and smoke generators play a vital role in laser shows, as they create an environment where the laser light becomes visible to the human eye. Laser light reflects off particles present in haze, smoke, mist, fog, rain, dust, or snow, enabling us to perceive the lasers. Hazers are often preferred over fog machines, as they produce a lighter and finer haze with longer dispersion times. Fog from foggers tends to be denser, descends rapidly, and leaves a sticky residue on surrounding surfaces, including sensitive laser show equipment.
When projecting laser graphic images, text, or animations in a laser light show, a suitable projection surface becomes essential. While a wall is commonly used as the projection surface, more elaborate and specialized mediums may be employed depending on the specific requirements of the event.
