In essence, a laser lights is device designed for the purpose of projecting laser lights primarily for entertainment applications. Typically, these stage lights, also referred to as stage lights , are comprised of one or more laser sources (typically red, green, and blue), which are amalgamated using an optical scanning system, accompanied by various driving electronics, and then integrated within a laser housing.
This configuration enables the projection of 2D and 3D laser content and objects. The control of laser lights, as mentioned previously, can take various forms. However, the most common methods involve PC control, lighting control, or DMX console control. Additionally, laser lights can operate autonomously in "auto-mode" when directed by an FB4 hardware device.
The front and rear components of a laser lights
Here, you can observe the typical construction of the stage laser lights outdoor . The high-quality laser lights will typically feature a housing with an IP54, IP65, or IP67 rating. IP54 is suitable for both indoor and outdoor events and can endure mild weather conditions. IP65, on the other hand, is ideal for all outdoor events and provides complete water resistance. Finally, IP67 offers full weather and water-proofing capabilities.

The Rear Panel of a Laser lights
Stage lights come equipped with control inputs, along with various adjustment and safety features, typically located on the rear panel.
Advanced stage lights, especially the more recent models, have embraced the evolution of laser technology. They now incorporate network-based laser controllers such as FB4 directly within the projector itself. This innovation significantly streamlines the process of setting up a laser show and simplifies the management of multiple laser lights.
The industry has adopted "FB4" as the standard network-based laser control system. This hardware seamlessly integrates into the laser unit, offering a broader range of control capabilities.
Essentially, FB4 functions as a miniature computer within the laser unit, granting control over all projector parameters, including color, safety features, geometric correction, and more. Furthermore, it supports various laser and lighting protocols, such as network, DMX, ArtNet, ILDA, and auto-mode, facilitating seamless integration with other production equipment. Additionally, it boasts a full-color display and an onboard memory system complete with a real-time clock (RTC).
Inside the laser projector - How does a laser projector work?
Newer laser models on the market tend to adopt the design similar to the one depicted below.
A laser lights works by combining different laser sources (usually red, green, and blue) and using an optical scanning system to project images or patterns onto a surface.
Here's a breakdown of how it works:
1.**Laser Sources**:
Inside a laser lights, you have red, green, and blue laser sources. These lasers are responsible for emitting the respective colors used in the projection.
2.**Optical Scanning System**:
The optical scanning system is a crucial part of the laser light. It consists of mirrors or other optical elements that can rapidly move to direct the laser beams precisely onto the desired points on the projection surface. This movement is what creates the images and patterns.
3.**Dichroic Filters**:
Dichroic filters are used to separate and combine the laser beams. They allow the different color laser beams to overlap and produce a full spectrum of colors. These filters are essential for creating the wide range of colors in the projected image.
4.**Drive Electronics**:
Drive electronics control the laser sources and the scanning system. They manage the intensity and timing of the laser beams to create the desired images or animations. These electronics ensure precise synchronization and control.
5.**Protective Housing**:
The entire system is enclosed in a protective housing. This housing not only protects the delicate components from external elements but also ensures safety by preventing laser lights from escaping and potentially harming people.
What are laser modules, and laser diodes?
Now, let's talk about laser modules and laser diodes:
**Laser Modules**:
A laser module is the light source inside a laser lights, like the lightbulb in a lamp. It's the heart of the projector and where the laser beams originate. Laser modules are available in various types, including gas laser tubes, NEWFEEL (Diode-Pumped Solid State) lasers, and diode lasers.
**Laser Diodes**:
Laser diodes are a key component within laser modules. They are responsible for emitting the actual laser light. Laser diodes work by passing an electrical current through a semiconductor material, which stimulates the emission of coherent laser light. They are compact, efficient.
