Laser light to create a dreamy atmosphere buy bear in mind that the ten points 2011-11-14 08:01:12 source: hits: 19 stage light moving head lights in addition to the professional level, the new keychain lights
Light, there is never out of date, with the magical charm of laser light. Many lanterns to create a dreamy effect, whether it is a large square of a large indoor studio or outdoor, have so
The purchase of laser light, you should note the following:
1, the time of purchase, spotted the power and spot diameter
Laser light beam fatal injuries to the human eye, the power of bigger and more dangerous! Spot diameter of less than 2mm, power greater than 100mW green laser beam is stationary, if the person is directly hitting the
The skin, then there is the burning feeling within a few seconds. One minute when the same spot, the power is greater than 300mW green laser beam directly hitting the led key chains clothes may be burn. So
Must not look directly at the stationary laser beam!
Laser show, laser beam, diffuse high-speed optical scanner, laser power is relatively large, but the laser power density per unit area after sweeping open already low, usually not
Eye caused by irreversible damage. However, if the circuit or scanning galvanometer failure caused by the laser beam in the normal scanning process suddenly stops moving, and this laser beam has just launched into
Eyes, then see how your luck. Light, your visual acuity decreased significantly, severe, immediate blindness!
The laser show is good-looking, but very dangerous! To solve this problem, and now Europe and the United States and other developed countries has developed a laser scanning Fail Safe "technology, laser lights with this technology
When unexpected stop scanning laser beam, the laser will automatically and immediately be turned off. Therefore, in order to protect you and your customer's eyes, you buy a laser show products must take note of this product
Whether there is "out of control laser scanning protection" function, and to verify this feature.
Two, look at the classification of the laser light
Currently available laser light from the scanning device classification of two groups. One is the simple beam scanning laser light, this type of laser light using low-speed stepper motor scanning, the effect of only some of Jane
Single repeat of the beam effect. The other is the galvanometer scanning laser light, usually this type of laser light can be put in the text and animation. Galvanometer scanning the laser light, can be divided into text the slow 10Kpps about
The character animation laser light and the ILDA standard> 30Kpps high-speed, high block of text animation laser light. Low-speed galvanometer scanning laser light can not normally be put in the complex high-quality text or animation, can not be a "multi-
Pattern of special effects. Mao Cheng uses 30Kpps high-speed galvanometer developed high-grade text animation laser light, can not only put high-quality text and animation, you can also put multiple patterns stunt
3, to see the actual efficacy of voice
The laser light has a "voice" function, the "voice" is actually a very simple volume trigger the laser playback, simple and monotonous. Laser music synchronization with the
Into play, "play with the laser performance data and music rhythm data synchronization synthesis, so that the background music with the laser speed and orderly manner with the rhythm of the music synchronization broadcast
Put, the effect is usually the "voice" effect can not be compared.
4, to see the artistic effect of the text animation
Currently available in the market known as text animation laser light are not broken pen "effect, the poor of the artistic sense of the text animation. The so-called "off the pen" when placing text with a word of strokes
, Or between two text should be no laser connection. Typically, low laser light are not broken pen "effect, put text or animation distortion greatly.
5 to see if it has multiple laser patterns stunt
Laser light show system functionality with multiple patterns stunt, then it can be put in effect on richer, you can simply say, such a single-head laser light can be put
Equivalent to the combined effect of two common single-head laser light.
6, look at the pros and cons of the galvanometer performance
Galvanometer directly affect the pattern of placing on the quality of key components, usually good galvanometer in the case of the same fidelity, can put more text; or in the same amount of text, put out the text
Distortion of the word small. Galvanometer can put high-quality text, but also can put high-quality, the more the laser effect patterns.
"DMX512" The smart
The market claimed that "the DMX512 control laser light is basically no programming, just a simple pattern to call, so that the laser light is usually rather monotonous. The "multi-function
DMX512 intelligent programming, provides a powerful programming and editing means of pictorial effect, the laser light can have such a function directly through the DMX512 console to edit the laser scene effects and procedures, with
Laser effects scene with the traditional stage lighting scene effect organic combination of short, mixed with laser light with DMX512 control computer lights can
Laser effects and lighting effects a perfect combination.
8, look at the indicators in line with the ILDA international standard
If the manufacturer of the laser light is not ILDA members of its products do not usually designed according to this standard, or to add a lot of cost.
9, to see the dust sealing measures how
Laser light within the optical lens reflex, if the internal dust sealing measures, dust and smoke oil will soon lens contamination, so that the reflection efficiency is reduced, the laser light so that
Need to be cleaned after a period of time, otherwise the brightness becomes very dark. But regular cleaning, high reflective film on the lens will be destroyed, and the reflection efficiency is lower. So there is no dust sealing measures stimulated
Light, although at the purchase feel the brightness can also be, but does not take long, 1-2 months after becoming very dark.
To determine a laser light dust control measures, as long as the laser output port is no a dust-proof glass. If not, it is certainly the manufacturers in order to save costs, did not take the dust
Measures. Laser light, in fact, cost is very poor, because it's real life is very short. Must pay attention to dust control measures in the purchase of laser light, if you are a dealer
Or engineering, your customer within 1-2 months because the laser brightness down to you to replace the laser light, you are not a lot of trouble?
10, look at the detection power of the nominal is true
At present, many domestic manufacturers of laser light may be due to the lack of laser expertise, often intentionally or unintentionally false (reported high) laser power to mislead customers and promote sales in order to achieve
Purpose. Often 50mW of laser nominal 100mW, 500mW green laser nominal 1000mW. If there is no laser expertise, experience or measurement tools to identify the actual power of the laser light
Indeed difficult, if you have doubts about the actual power of the laser light, the easiest way is to two laser light spot contrast, or consult a laser expert.
Laser light with bright colors, high brightness, good point, long range, easy to control, etc., looks more magical fantastic feeling, it is generally used in buildings, parks, squares,
Theater, a variety of performances, mainly the use of laser beam divergence, and to attract to a few kilometers away people's eyes, issued from the laser point has become the focus of attention. If the laser light
Placed in high-rise or the Peak Scenic Area, the beam fired into the distance, the air a bunch of bright green, very bright beam can swing up and down, within a radius of several kilometers can enjoy it God
Odd gorgeous face.
If used outdoors, such as the laser light emitted laser fired water curtain, building or wall, laser scanning system is under the control of fast-moving form text, graphics, etc. for viewing. To
For indoor viewing, such as laser light is installed in theaters, nightclubs, dance halls and other places. With dry ice smoke, laser beam is fired at the smoke and scanned, and also the formation of the text,
Case, the animation effect. Intensity of the laser show can also be played with the music that gorgeous bright colors intoxicating linger, of course, under normal circumstances, the laser light is the most commonly used for nightclubs, dance halls, a variety of speech
Out activities, theaters, outdoor advertising and landmarks and so on.
