Laser stage light introduction How to choose laser stage light?
Professionally speaking, the stage laser light is a laser product that can automatically produce various laser beams, laser patterns, and laser texts according to the rhythm of the music. I believe many people who have been to bars and dance halls should have seen it, but Maybe you don’t know much, but it’s okay. Below, BENWEI LIGHTING will explain the laser stage lights for everyone, and see how to buy laser stage lights? Let's take a look.
Laser stage light
Laser stage light introduction:
Stage laser lights include monochromatic laser lights and full-color laser lights, which are usually divided into high-power stage laser lights and low-power laser lights according to their power.
Low power laser light
A laser product that can automatically produce various laser beams, laser patterns, and laser texts according to the rhythm of the music. It is a new product commonly used in stages, dance halls, bars, KTVs, family parties... to increase the atmosphere. The specific models are: monochromatic laser light, two-color/three-color/full-color laser light, gypsophila laser light, firefly laser light, animation laser light, the following are the relevant parameters of gypsophila laser light for reference.
Model: xl-09, red and green two-color laser fireworks, gypsophila
Features: Red and green double-color laser fireworks, laser spot beams and fireworks effects, matrix distribution of light points, the number of light points is greater than 1000, the scattering angle is greater than 40 degrees, the position and brightness of the light points are evenly distributed, and the laser points are controlled by the movement trajectory and speed. The collision of dots and dots blooms countless star dots, achieving a firework-like demonstration effect, with effects such as rotation direction, rotation speed, strobe, and color control. Advanced algorithm program design, not only DMX512 signal control, but also stand-alone or self-online synchronization work. The voice control mode has the function of sound control and light-off.
Laser power is less than 1000mW: 50mW green laser (532nm), 100mW red laser (650nm)
Control mode: voice control, automatic, master-slave synchronization
Safety and intelligence: The voice-activated mode has the function of sound-controlled light-off; in the master-slave synchronous auto-on-line mode (up to dozens of slaves can be connected), the slave will automatically turn off the light when there is no signal. In accordance with the safety and reliability design, single-point lasers are avoided under any circumstances, which is safer for the human body and the environment.
Power supply: voltage 220V/110V, frequency 50-60HZ,
Application places: weddings, discos, dance halls, bars, KTV boxes, family parties...
High-power stage laser light
The power of high-power laser lights is mostly above 1W. There are 2W, 3W, 5W commonly used single green stage laser lights, and 6W, 10W, 15W lights RGB full-color stage laser lights. Generally, it is illuminated by DPSS and controlled by Pangolin and other control software. It can perform laser people, laser dances, laser shows, etc. Laser show technology is a technology that integrates sound, light, electricity and machine. Different methods can produce different effects and create a colorful atmosphere.

How to buy laser stage lights?
1. Pay attention to the power and spot diameter when purchasing
The beam of the laser light is fatal to human eyes. The greater the power, the more dangerous! A stationary green laser beam with a spot diameter of less than 2mm and a power greater than 100mW, if it directly hits the human skin, it will be destroyed in a few seconds. There is a burning sensation. When a green laser beam with a power greater than 300mW directly hits clothes with the same spot, the clothes may be burnt through within one minute. Therefore, never look directly at the stationary laser beam!
During a laser show, the laser beam is scanned and dispersed by a high-speed galvanometer. Although the power of the laser is relatively large, the laser power density per unit area after scanning is already very low, which usually does not cause irreversible damage to human eyes. . However, if the laser beam suddenly stops moving during normal scanning due to malfunctions of the circuit or the scanning galvanometer, and the laser beam just hits your eyes, then it depends on your luck. In the mild case, your vision will be significantly reduced, in the severe case, you will lose sight immediately!
Laser shows are beautiful, but dangerous! In order to solve this problem, developed countries such as Europe and the United States have developed a set of "laser scanning out-of-control protection" technology. After the laser light is equipped with this technology, when the laser beam stops scanning unexpectedly, the laser It will be closed immediately and automatically. Therefore, in order to protect the eyes of you and your customers, you must pay attention to whether the product has the "laser scanning out-of-control protection" function when purchasing a laser demonstration product, and verify this function.
2. Look at the classification of laser lights
Currently, there are two types of laser lights on the market from the scanning device. One type is a simple beam scanning laser light. This type of laser light uses a low-speed stepper motor to scan, and its effect is only some simple repetitive beam effects. The other type is galvanometer scanning laser light, usually this type of laser light can put text and animation. Galvo scanning laser lights can be divided into low-speed text animation laser lights of about 10Kpps and ILDA standard >30Kpps high-speed mid-to-high-speed text animation laser lights. Low-speed galvanometer scanning laser lights usually cannot deliver complex and high-quality text or animation, nor can they produce "multi-pattern special effects". Maocheng adopts >30Kpps high-speed galvanometer to develop medium and high-end text animation laser lights, which can not only display high-quality text and animation, but also display "multi-pattern special effects" effects.
3. Look at the actual effect of voice control
Nowadays, many laser lights have a "voice control" function, this "voice control" is actually a very simple volume trigger laser playback function, the effect is simple and monotonous. "Laser Music Synthesized Playback" is to synthesize the laser effect data and the music related rhythm data and play them together. In this way, with the cooperation of the background music, the laser is played quickly and orderly with the rhythm of the music, and the effect is normal. The "voice control" effect is incomparable.
4. Look at the artistic effects of text animation
At present, many so-called text animation laser lights on the market do not have a "broken pen" effect, and the artistic sense of text animation is very poor. The so-called "broken pen" means that there should be no laser connection between the strokes of the same character or between two characters when placing text. Generally, low-end laser lights do not have a "pen-breaking" effect, and the text or animations they cast are highly distorted.
5. See if you have "multiple laser pattern special effects"
If the laser light or performance system has the function of "multi-pattern special effects", the effects that can be put on will be more abundant. It can be simply said that such a single-head laser light can be used as a combination of two ordinary single-head laser lights. Effect.
6. Look at the pros and cons of the "galvanometer" performance
The galvanometer is a key component that directly affects the quality of the image delivery. Generally, a good galvanometer can deliver more text with the same fidelity; or under the same number of texts, the distortion of the text delivered by it is less. A galvanometer that can put high-quality text, can also put high-quality, more effective laser effect patterns.

7. Look at the intelligence of "DMX512"
Many laser lights on the market that claim "DMX512 control" basically don't have a programming function, but simply call patterns. Such laser lights usually have a monotonous effect. And "multifunctional DMX512 intelligent programming" provides powerful programming and pattern effect editing methods. The laser light with this function can directly edit the laser scene effects and programs through the DMX512 console, and at the same time, the laser effect scene can be compared with the traditional stage The lighting scene effects are organically combined. In short, you can mix such laser lights with DMX512-controlled computer lights to achieve a perfect combination of laser effects and lighting effects.
8. To see whether the indicator meets the ILDA international standard
If the manufacturer of the laser light is not a member of ILDA, then its products are usually not designed according to this standard, otherwise it will increase a lot of costs.
9. Look at the dust-proof sealing measures
There are some optical reflective lenses inside the laser lamp. If there is no dust-proof sealing measure inside, dust and smoke oil will quickly contaminate the lens, so the reflection efficiency will be reduced. The laser lamp needs to be cleaned after a period of use, otherwise the brightness will be reduced. It will become very dark. But if it is cleaned frequently, the highly reflective film on the lens will be destroyed and the reflection efficiency will be lower. Therefore, the laser light without dust-proof sealing measures, although the brightness is good when it was first purchased, it will not be long after use, and it may become very dark after 1-2 months.
