Tips For Buying High-Quality Laser Light - NFL Laser

by Newfeel Ho on Dec 07, 2022

With the continuous progress of laser technology, stage laser light products are also used in a wider range of fields, such as scenic laser lights, landmark laser lights on outdoor roofs, theater laser lights in entertainment venues, bar laser lights, KTV private room laser lights, etc. . NF-LASER is a professional manufacturer of various laser light equipment.
What kind of laser light to choose, it depends on your needs and where it is used to choose laser light with different functions, such as laser light power, laser effect, laser color, laser control method, etc.
1. For outdoor rooftop lasers, landmark lasers need to be selected. This product is characterized by high brightness, long range, strong visual impact, rich program changes (with viewing), and laser effects can be seen in different areas of the city, so that it has advertising effects. Landmark laser light requires high-power laser light, 360-degree shaking head, can scan to any position, and can also scan directionally; flexible program changes (programs can be updated), convenient and simple operation, automatic control, etc. (time switch, constant temperature control).
2. There are a wide range of choices for theater laser lights and bar laser lights . The main products with relatively high power, generally have more products above the watt level. There are high-power color lasers, high-power green lasers, laser platforms, laser rain products, etc. The characteristics of this type of product are strong editability, high laser power, strong visual impact, and cheerful rhythm.

3. For KTV private room lasers, you need to choose the Starry Star series laser and small laser. The private room has a small space, and the music changes in a variety of ways, so the patterns need to be rich in changes, and the program can be flexibly changed with the music. The private room laser is mainly based on the gypsophila laser. Since 2005, with the rapid development of the grating technology, the gypsophila laser has increased the variety of the gypsophila laser, and the variety of this series is dazzling. In terms of effect, it is mainly divided into firefly laser, bubble laser, small magic flower laser, pattern laser (4 patterns, 6 patterns, 8 patterns, 20 patterns, etc.), galvanometer gypsophila, three-dimensional gypsophila, Gypsophila and LED combination and so on. There are also single-color, double-color, three-color, and color according to color; some small and medium-sized laser lights such as beam-type laser lights and animation-type laser lights are also used in some private rooms. The selection of lamps and lanterns in such places is mostly linked to price. High-end places use laser gypsophila with novel effects and many patterns, and some VIP private rooms also have color laser lights, which can make laser lights with effects such as KTV LOGO; ordinary places are affected by investment and use gypsophila at cheaper prices.

In addition to professional computer moving head lights and new LED stage lights, stage lighting also has timeless and magical stage laser lights. Many light groups create a dreamy effect, whether it is a large indoor studio or a large outdoor square, it has such a feeling.
When buying a laser light, you should pay attention to the following points:

1. Look at the power and spot diameter when purchasing

The beam of the laser light is fatal to human eyes, 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 will feel a burning pain within a few seconds if it directly hits the human skin. 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 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 lamp is equipped with this technology, when the laser beam stops scanning unexpectedly, the laser will be automatically turned off 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.

2. Look at the classification of laser lights

There are two types of laser lights on the market at present. 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.

3. Look at the actual effect of voice control

Many laser lights now 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.

4. See the artistic effect of text animation

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.

5. See if it has "multiple laser pattern stunts"

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.

6. Look at the pros and cons of the performance of the "galvanometer"

The galvanometer is a key component that directly affects the quality of pattern delivery. Generally, 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 less. The galvanometer that can put high-quality text can also put high-quality, more effective laser effect patterns.

7. Check the intelligence of "DMX512"

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.

8. Check whether the indicators meet the ILDA international standards

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

9. See how the dustproof sealing measures are

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, if it is cleaned frequently, the high 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 I think the brightness is OK when I first buy it, but it will become very dark after 1-2 months.
To judge whether a laser light has dustproof measures, just check whether the output port of the laser has a dustproof glass. 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 the brightness of the laser decreases. Do you feel very uncomfortable? trouble?

10. See if the detection power rating is true

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 emitted by the laser light is directed to the water curtain, building or wall, etc., the laser moves rapidly under the control of the scanning system, forming 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.
