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.
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, 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.
2. Look at the classification of laser lights
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.
3. Look at the actual effect of voice control
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.
4. Look at 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. 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.
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. See if the indicators meet the ILDA international standards
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.
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, 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.
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 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.
