Stage lighting In addition to professional-grade computer moving head lights, new LED stage lights, there are never outdated, magical stage laser light. Many lights create a fantastic effect, whether it is a large indoor studio or outdoor large square, have this feeling.

When buying laser light, should pay attention to the following points:

1, the purchase must see the power and spot diameter size

Laser beam of light on the human eye have fatal injuries, the more power the more dangerous! A stationary green laser beam with a spot diameter of less than 2 mm and a power greater than 100 mW will burn within seconds if illuminated directly to the human skin. When the same spot, the power of more than 300mW green laser beam directly onto the clothes, within a minute, the clothes may be burned through. So, absolutely can not look straight motionless laser beam!

Laser show, the laser beam is scattered by the high-speed galvanometer scanning, although the laser power is relatively large, but after the laser power density per unit area has been very low, usually does not cause irreversible damage to the human eye . However, if your laser beam abruptly stops during the normal scan due to a malfunction such as a circuit or a scanning mirror, and the laser beam is just getting in your eyes then look at your luck. Light, your vision decreased significantly, severe cases, immediately blind!

Laser show looks good, but very dangerous! In order to solve this problem, the developed countries such as Europe and the United States have now developed a set of technologies called "laser scanning runaway protection". After the laser is equipped with this technology, the laser will be automatically and immediately shut down when the laser beam stops scanning unexpectedly. Therefore, in order to protect the eyes of you and your customers, when you purchase the laser demo product, we must pay attention to whether the product has "laser scan out of control" function, and to verify this function.

2, look at the classification of laser light

Currently on the market of laser light, from the scanning device on the classification of two categories. One is the simple beam scanning laser light, such laser light scanning using low-speed stepper motor, the effect is only some simple repetitive beam effect. The other is the galvanometer scanning laser light, usually this type of laser light can put text and animation. Galvanometer scanning laser light, but also can be divided into low-speed 10Kpps text animation laser light and ILDA standard> 30Kpps high speed medium and high block text animation laser light. Low-speed galvanometer scan laser usually can not put complex high-quality text or animation, can not be a "multi-pattern effects" effect. Mao-Cheng> 30Kpps high-speed galvanometer developed by the high-grade text animation laser light, not only can put high-quality text and animation, you can also put "multi-pattern effects" effect.

3, to see the actual effect of voice control

Now many laser lights have "voice" function, the "voice" is actually a very simple volume-trigger laser playback, the effect is simple, monotonous. The "laser music sync synthetic playback" is the laser effect data and music related rhythm data synchronized with the synthesis of play, so with the background music, the laser light in an orderly manner and pace of music playback, the effect is usually The "voice" effect can not be compared.

4, look at the artistic effect of text animation

Currently on the market a lot of known text animation laser lights are not "broken pen" effect, the art of text animation is very poor. The so-called "broken pen" is when putting the text, the same word strokes, or between two words should be no laser connection. Normally, low-end lasers do not have a "broken pen" effect, which puts a great deal of text or animation in distortions.

5, to see if there is "multiple laser pattern stunt"

A laser or performance system can have a richer effect if it has the "Multi-Pattern Effect" feature, so simply put it, a single-head laser can deliver the equivalent of a combination of two ordinary single-head laser lights effect.

6, look at the "galvanometer" the pros and cons of performance

The galvanometer is a key component that directly affects the quality of the pattern. Generally, the good galvanometer can put more words under the same fidelity, or the text with less distortion in the same number of characters. High-quality text can be placed in the galvanometer, but also put high-quality, more effect laser effect pattern.

7, to see "DMX512" smart or not

Many on the market claim that the "DMX512 control" laser lights are basically no programming function, just a simple pattern call, such a laser light is usually more dull. The "multi-function DMX512 intelligent programming," provides a powerful programming and pattern effects editing tools, with such a function of the laser light can be directly through the DMX512 console to edit the laser scene effects and procedures, while the laser effects can be the scene with the traditional stage Light scene effects organic combination, in short, you can put such a laser light and DMX512 control computer lights mixed use, you can achieve the perfect combination of laser effects and lighting effects.

8, to see if the indicator is in line with ILDA international standards

If the manufacturer of the laser light is not a member of the ILDA, then its products are usually not designed to this standard, otherwise it will add a lot of cost.

9, to see how the dust seal

Laser light there are some internal optical reflex lenses, dust-proof seal if the internal measures, then the dust and tobacco will quickly pollute the lens, so the reflection efficiency will be reduced, the laser light used for some time after cleaning, or brightness Will become very dark. However, regular cleaning, high-reflective film on the lens will be destroyed, the reflection efficiency is lower. So there is no laser dust seal measures, although the brightness just bought can feel, but in less time, it may be 1-2 months after it becomes very dark.

Determine whether there is a laser light dust-proof measures, as long as it see the laser output is not a piece of dust-proof glass. If not, it is definitely the manufacturer in order to save costs, did not take dust-proof measures. Such a laser light, in fact, the price is very poor, because of its very short useful life. Therefore, the purchase of laser lights must pay attention to whether there are dust-proof measures, if you are a dealer or contractor, your customers within 1-2 months because the laser brightness decreased, you want to change the laser light, do you think it is trouble?

10, to see if the nominal power test is true

At present, many domestic manufacturers of laser lights may be due to the lack of laser expertise, often consciously or unconsciously using false (reported high) laser power to mislead customers, in order to achieve the purpose of promoting sales. Often the 50mW laser is nominally 100mW and the 500mW green laser is nominally 1000mW. Without laser expertise, experience, or measurement tools, it is really difficult to identify the actual power of a laser light. If you are suspicious of the actual power of a laser light, the easiest way is to compare the two laser lights in the field or ask for a laser Hipster.

Laser lights with bright colors, high brightness, good directivity, long range, easy to control, etc., looks more magical and fantastic feeling, it is generally used in buildings, parks, squares, theaters, various performances, mainly the use of The non-divergence of the laser beam can attract people's eyes as far as a few kilometers away from the point of laser emission has become the focus of attention. If the laser light placed in the high-rise or the Peak Scenic Area, the beam fired afar, a bright green light appears in the sky, very bright, the beam can be swung up and down, within a radius of a few kilometers can enjoy its magical gorgeous face .

If used outdoors, such as laser light emitted laser shooting water curtains, buildings or walls, etc., laser scanning system under the control of rapid movement, the formation of words, patterns, etc. for viewing. For indoor viewing, such as laser light installed in theaters, nightclubs, dance halls and other places. With a certain dry ice smoke, the laser beam is directed at the smoke and scanning, can also form a text, graphics, animation effects. Of course, laser light is most commonly used in nightclubs, song and dance halls, performances, theaters, outdoor advertising and landmarks, etc. Of course, laser light is most commonly used in nightclubs, dance halls, various performances, theaters, outdoor advertisements and landmarks.
