Laser Light buying tips

Release Date:2014-07-07 15:01:50    Click rate:
In addition to the professional stage lighting stage moving head lights, new LED stage lights, and timeless, with a stage laser lights. Stage laser light is a laser beam can be automatically played various laser pattern, laser writing laser products rhythm with the music, is to increase the stage, dance halls, bars, KTV, theater, television, concerts, family party atmosphere in common a new product.

When buying a laser light, you should note the following:

1, to be spotted buying power and spot diameter size

Laser light beam to the human eye has a fatal injury, the greater the power, the more dangerous! Spot diameter of less than 2mm, the stationary power greater than 100mW green laser beam, if directly hitting the skin, then within a few seconds on a burning feeling. When the same spot, power more than 300mW green laser beam shines directly on the clothes, within one minute, the clothes may be burn. So, absolutely not look stationary laser beam!

When laser show, laser beam is spread high-speed galvanometer scanning, although the laser power is relatively large, but after opening sweep of the laser power density per unit area has been very low, people usually do not cause irreversible eye damage . However, if the scanning galvanometer circuits or other faults caused by the laser beam in the normal scanning process suddenly stops moving, And this is just another incident laser beam in your eyes, then see how your luck. Light, your vision decreased, severe, immediate blindness!

Laser show good-looking, but very dangerous! To solve this problem, Europe and other developed countries have now developed a set of "laser scanning failsafe" technology, laser light with this technique, the laser beam stopped unexpectedly when scanning laser will automatically be turned off immediately. Therefore, in order to protect you and your customer's eyes, when you buy a laser presentation products must pay attention to whether the products are "laser scanning failsafe" function, and to verify this feature.

2, to see the classification of laser light

Currently available laser light from the scanning device classification of two groups. One is a simple beam scanning laser lights, laser lights using such low stepper motor scanning, the effect is only a few simple repetitive beam effects. Another is the galvanometer scanning laser lights, laser lights can usually put this kind of text and animation. Galvanometer scanning laser light, they can be divided into low-speed 10Kpps about text animation laser lights and ILDA standard> 30Kpps high-speed block text animation laser lights. Low-speed galvanometer scanning laser lights usually can not put text or a complex of high-quality animation, nor the "multiple patterns stunt" effect. Mao Cheng used> 30Kpps speed galvanometer development of high-grade text animation laser light, not only can put high-quality text and animation, you can also put "multiple patterns stunt" effect.

3, look at the actual effectiveness of the voice of

Now many laser lights have a "voice" function, the "voice" is actually a very simple laser trigger playback volume, the effect of simple, monotonous. The "laser sync music synthesizer player" is a play together after the laser effects associated rhythm data to synchronize data and music synthesis, so in the context of music with laser speed synchronous playback and orderly rhythm of the music, the effect is usually the "Voice" results can not be compared.

4, see text animation artistic effect

Many of the current market known as text animation laser lights are not "broken pen" effects, text animation art feeling poor. The so-called "broken pen" is that when put in writing, between strokes with a word, or there should be no connection between the two text laser. Typically, low-grade laser lights are not "broken pen" effect, large text or animated distortion of its launch.

5, to see whether they have "multiple laser pattern stunt."

If the laser light or performing system with "multiple patterns stunt" feature, so it can be put in effect is more abundant, can simply say that such a single head laser lights can be put in the equivalent of two ordinary single head laser light combination effect.

6, see "galvanometer" The performance of the merits

Galvanometer is put directly affect the pattern of the key components of quality usually good galvanometer fidelity in the same situation, I can put more text; or in the number of the same text, which put out a small distortion of the text. Able to put high-quality text galvanometer can also be put in high-quality, laser effects more effect pattern.

7, see "DMX512" smart or not

Many claimed that the market "DMX512 control" laser lights basically no programming function, simply call patterns, such as the effect of the laser light is usually rather monotonous. The "multi-functional intelligent programming DMX512," provides a powerful programming and pattern effects editing tools, with such features laser light can be directly edited by the laser scene effect and procedures DMX512 console, while the effect of the laser with the traditional stage scene scene lighting effects combine organic, in short, you can put this laser light with DMX512 control computer lights mixed use, laser effects can be achieved with the perfect combination of lighting effects.

8, to see whether the ILDA international standard indicators

If the manufacturer is not a member of ILDA laser light, then its products usually are not on the standard design, or to increase a lot of costs.

9, to see how the dust sealing measures

There are some internal optical laser lens reflex, if no internal dust sealing measures, the dust and smoke oil pollution will soon put the lens, so the reflection efficiency is reduced, laser lights need to be cleaned after a period of time, otherwise the brightness of become very dark. But regular cleaning, high-reflection film on the lens will be destroyed, reflecting lower efficiency. So there is no dust sealing measures laser light, although just think brightness can also be purchased, but before long, after 1-2 months may become very dark.

There is no judgment of a laser light dust control measures, as long as the laser's output to see if it there a dust-proof glass. If not, it is certainly the manufacturer in order to save costs, did not take dust control measures. Such a laser light, in fact, is very poor value for money, because it's real life is very short. So when choosing a laser light must note that there is no dust control measures, if you are a reseller or engineering, your customers because the laser brightness decreased within 1-2 months, you should replace the laser light, you feel very trouble?

10, to see whether the nominal power to detect true

Many domestic manufacturers of laser light may be due to a lack of laser expertise, often unintentionally using false (reported high) laser power to mislead customers, in order to achieve the purpose of promoting sales. Often 50mW laser nominal 100mW, 500mW green laser the nominal 1000mW. If there is no laser expertise, experience or measurement tools, identification of the actual power of the laser light is indeed difficult, if you actually have doubts about the power of laser light, the easiest way is to compare the two laser light spot, or ask laser aspects expert.

Laser light with bright colors, high brightness, good point, long range, easy to control, etc., look more magical fantastic feeling, it is generally used in buildings, parks, plazas, theaters, a variety of performances, mainly using no divergence of the laser beam, can attract a few kilometers away to people's eyes, issuing point has become the focus of attention from the laser. If the laser light placed in tall buildings or Peak Scenic Area, beam fired from afar, the air appeared a bunch of bright green, very bright beam can swing up and down within a radius of several kilometers can appreciate its amazing gorgeous face .

If used outdoors, such as laser light emitted by a laser fired water curtain, such as buildings or walls, moving quickly under the control of the laser scanning system, the formation of text, graphics, etc. for viewing.

As for indoor viewing, such as laser lights installed in theaters, nightclubs, dance halls and other places of. With some dry ice smoke, fumes and fired a laser beam scanning, also form text, graphics, animation effects. Music can also be played with intense laser light show, and that gorgeous bright colors intoxicating linger! Of course, under normal circumstances most commonly used laser light nightclubs, dance halls, a variety of performances, theaters, outdoor advertising and landmarks, etc.
