Laser technology, with its intricate specifications and attributes, can be bewildering for those looking to purchase laser light projector. To aid you in your quest for understanding these critical details while shopping, this article aims to elucidate common laser terminology using straightforward language and real-world examples.
Wavelength and Color
One of the fundamental characteristics of lasers is their wavelength, quantified in nanometers (nm), which also dictates their color. Various wavelengths manifest as distinct visible colors:
- 405nm – Violet
- 532nm – Green
- 638nm – Red
- 445nm – Royal Blue
- 650nm – Deep Red
For laser light projector with multiple colors, dj laser lights amalgamate diverse wavelengths such as red, green, and blue into a single unit or employ wavelength mixing to create a spectrum from a solitary laser diode.
Scan Rate (KPS)
Scan rate, often referred to as KPS, denotes a laser's scanning speed, measured in kilo scans per second. It determines how swiftly the device can project animations and graphics with precision:
- Low-speed lasers below 4KPS are suitable for uncomplicated beam effects.
- High-speed lasers with a rating of 12KPS or more are ideal for club environments featuring intricate graphics.
- A scan rate of 20KPS supports highly intricate animations, including detailed logos or text.
Diode Type
Laser diodes are responsible for generating the laser beam. Notable diode types encompass:
- IR Diodes, producing infrared wavelength beams that are invisible to the naked eye.
- RGB Diodes, emitting red, green, and blue visible laser beams.
- Laser Modules, integrating multiple diodes and optics into a singular unit.
Optimal efficiency and brightness are assured with high-quality diodes from reputable brands like Osram.
Scanner Type
The scanner serves as the mechanism for directing and controlling laser beam movement through mirrors:
- Galvo Scanners facilitate swift beam steering through micro-mirror movement, primarily employed for graphic displays.
- Polygon Scanners utilize rotating optics, enabling faster and more complex laser effects.
- Hybrid Scanners amalgamate the attributes of both types for enhanced versatility.
Superior mirror quality results in higher scan rates and greater accuracy.
Optical Power
Optical power quantifies the output of the laser diode, measured in milliwatts (mW). Increased power translates to a brighter projection:
- Low power lasers, emitting less than 100 mW, fall into Class 3R.
- Mid-power lasers range between 100 and 499 mW, categorized as Class 3B.
- High-power lasers emit 500mW or more and belong to Class 4.
The ideal power requirement depends on the venue size and ambient lighting conditions.
Beam Count
Incorporating multiple laser diodes can result in the simultaneous projection of laser beams of different colors. Beam count signifies how many beams are produced by a single unit. For instance, a laser with three beams emits separate red, green, and blue lasers.
Greater beam counts allow for more vivid and intricate effects but typically entail a higher cost. For most DJs, lasers with three or five beams provide a good balance.
Control and Programming
In addition to manual control knobs, common laser programming options include:
- DMX Control: Enables the connection of lighting consoles to choreograph laser shows, synchronize motions with music, and integrate with tv star shower laser lights.
- ILDA: Employs PC-driven laser show control software to project graphics, text, and animations. - Standalone: Incorporates built-in show modes like sound activation and automatic patterns.
The choice of programming should consider your specific needs and technical proficiency.
Key Takeaways
While laser terminology may seem intricate initially, understanding fundamental specifications such as wavelength, scan rate, power output, and control modes provides a clear picture of a laser light projector's capabilities. This knowledge is instrumental in selecting the perfect laser to meet your DJing requirements.
We trust that this breakdown has demystified laser terminology and will assist you in making well-informed decisions. If you need help choosing a professional laser projector to enhance your event, feel free to ask NEWFEEL laser.
