Laser Lights Shopping Guide——2023 NewFeel Laser

In addition to professional-grade computer moving head lights and new LED stage lights, stage lighting also has timeless and stage laser lights. The stage laser light is a laser product that can automatically print various laser beams, laser patterns and laser texts with the rhythm of music. a new product.

The beam of the laser light is fatal to human eyes, and the higher the power, the more dangerous it is! 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 disappear within a few seconds. There is a burning sensation. When the same spot, the green laser beam with power greater than 300mW directly hits the clothes, the clothes may be burnt through within a minute. Therefore, never look directly at a stationary laser beam!

During the laser show, the laser beam is scattered by the high-speed galvanometer scanning. Although the power of the laser is relatively high, the laser power density per unit area after sweeping is very low, which usually does not cause irreversible damage to human eyes. . However, if the laser beam suddenly stops during the normal scanning process due to a fault such as a circuit or a scanning galvanometer, and the laser beam just hits your eye, then it depends on your luck. In mild cases, your eyesight will be significantly reduced, in severe cases, you will be blinded immediately!

The laser show is beautiful, but it is very 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 will be automatically closed immediately. Therefore, in order to protect the eyes of you and your customers, when you purchase a laser demonstration product, you must pay attention to whether the product has the laser scanning out-of-control protection function, and verify this function.

At present, there are two types of laser lights on the market, which are classified from scanning devices. One is a simple beam scanning laser light, which uses a low-speed stepper motor to scan, and its effect is only some simple and repeated beam effects. The other type is the galvanometer scanning laser light, usually this kind of laser light can put text and animation. The galvanometer scanning laser light can be divided into a low-speed text animation laser light of about 10Kpps and an ILDA standard 30Kpps high-speed text animation laser light with high speed. Low-speed galvanometer-scanning lasers generally cannot deliver complex, high-quality text or animation, nor can they produce multi-pattern effects. Maocheng uses 30Kpps high-speed galvanometer to develop mid-to-high-end text animation laser lights, which can not only deliver high-quality text and animation, but also deliver multiple pattern special effects effects.

Nowadays, many laser lights have a voice control function. This voice control is actually a very simple volume-triggered laser playback function. The effect is simple and monotonous. And laser music synchronous synthesis and playback is to synchronously synthesize the laser effect data and the relevant rhythm data of the music and play them together. In this way, with the cooperation of the background music, the laser is played in an orderly and synchronous manner with the rhythm of the music, and the effect is usually The voice control effect is incomparable.

At present, many of the so-called text animation laser lights on the market do not have the 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 word or between two words when the text is placed. Usually, low-end laser lights do not have a broken pen effect, and the text or animation they deliver is highly distorted.

If the laser light or performance system has the function of multi-pattern special effects, then the effects that can be cast will be more abundant. It can be simply said that such a single-head laser light can be cast equivalent to the combination of two ordinary single-head laser lights effect.

The galvanometer is a key component that directly affects the quality of pattern delivery. Usually, a good galvanometer can deliver more text with the same fidelity; or under the same number of characters, the distortion of the text it delivers is smaller. The galvanometer that can put high-quality text can also put high-quality, more effective laser effect patterns.

Many laser lights on the market claiming DMX512 control basically have no programming function, just simple pattern calls. Such laser lights usually have a monotonous effect. The multi-functional DMX512 intelligent programming provides powerful programming and pattern effect editing methods. Laser lights with such functions can directly edit laser scene effects and programs through the DMX512 console. The scene effects of lighting are organically combined. In short, you can mix such laser lights with computer lights controlled by DMX512 to achieve the perfect combination of laser effects and lighting effects.

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 cost.

There are some optical reflective lenses inside the laser lamp. If there is no dust-proof sealing measure inside, the lens will be polluted by dust and e-liquid, which will reduce the reflection efficiency. The laser lamp needs to be cleaned after a period of use, otherwise the brightness will be reduced. will get very dark. However, with frequent cleaning, the high-reflection film on the lens will be destroyed and the reflection efficiency will be lower. Therefore, the laser light without dustproof sealing measures, although the brightness is acceptable when it is first purchased, it will become very dark after 1-2 months after a long time.

To judge whether a laser light has dust-proof measures, just look at whether there is a dust-proof glass at the output port of the laser. If not, it must be that the manufacturer has not taken dust-proof measures to save costs. Such a laser light is actually very cost-effective because its actual service life is very short. Therefore, when purchasing laser lights, you must pay attention to whether there are dust-proof measures. If you are a dealer or an engineering company, your customers want you to replace the laser lights within 1-2 months because of the decrease in the brightness of the laser light. Do you feel very uncomfortable trouble.

At present, many domestic laser lamp manufacturers, probably due to lack of laser expertise, often deliberately or unintentionally use false reports (higher) 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. If you don't have laser professional knowledge, experience or measuring tools, it is really difficult to identify the actual power of the laser light. If you have doubts about the actual power of the laser light, the easiest way is to compare the two laser lights on-site, or ask for laser advice. expert.

Laser light has the advantages of bright color, high brightness, good directivity, long range, easy control, etc. It looks more magical and dreamy, so it is generally used in buildings, parks, squares, theaters, various performances, etc. The non-divergence of the laser beam can attract the attention of people as far as several kilometers away, and the point from which the laser is emitted has also become the focus of attention. If the laser light is placed in a high-rise building or a mountain top scenic spot, the beam will be directed into the distance, and a bright green light will appear in the sky, which is very dazzling.

If it is used outdoors, for example, the laser light emitted by the laser light shoots towards the water curtain, building or wall, etc., the laser moves rapidly under the control of the scanning system to form characters, patterns, etc. for viewing.

As for indoor viewing, for example, laser lights are installed in theaters, nightclubs, dance halls and other places. With a certain amount of dry ice smoke, the laser beam is directed to the smoke and scanned, and text, patterns and animation effects can also be formed. You can also play an intense laser show with music, and the gorgeous and bright colors are intoxicating and lingering! Of course, in general, laser lights are most commonly used in nightclubs, dance halls, various performances, theaters, outdoor advertising, and landmarks.
