There are two types of laser lights, one is industrial laser light and the other is entertainment laser light. The laser light generates a light beam through a krypton lamp and a crystal rod, and after frequency conversion, it can form visible light. It can also use a computer to control the high-speed deflection of the galvanometer to form characters and patterns of various shapes. The characteristics of the laser light are many colors, strong brightness, good directivity, long-range, easy to operate, etc., a variety of effect changes looks gorgeous and colorful, and can be used in various places.
When buying a laser light, you should pay attention to the following points:
1. The size of power and spot diameter
The brightness of the laser light is very high. The greater the power, the stronger the light produced. Too strong beams are harmful to human eyes and skin. When a stationary green laser beam with a laser light spot diameter of less than 2mm and a power greater than 100mW hits the eyes or skin directly, human eyes and skin will be burned and damaged.
Avoid direct contact with the stationary laser beam.
When the laser light is performing, the laser beam is already scanned and dispersed, the power per unit area has been reduced, and the damage to human eyes has also been reduced. Although the power of the laser is relatively large, the laser power density per unit area after sweeping is already very low, and it usually does not cause irreversible damage to human eyes. However, if the circuit or the scanning galvanometer fails, the laser beam may stay still during the scanning process. If your eyes just touch the laser beam, it will cause your eyesight to decline or blindness. The effect produced by the laser light is particularly beautiful, and it is most suitable for performance, but there is a certain degree of danger. But now that the “laser scanning out of control protection” function is available, it is best to choose a laser light with this function when purchasing products. When the laser beam stops scanning unexpectedly during the normal scanning process, the laser light will turn on the protection system and immediately automatically shut down.
2. Types of laser lights
The types of laser lights can be divided into two types in terms of scanning. The first type is simple beam scanning laser lights, whose effects are only simple beam effects. The second is the galvanometer scanning laser light, which is a laser light with the artistic effects of text animation. The galvanometer scanning laser light can be divided into a low-speed galvanometer scanning laser light of about 10Kpps and a high-speed mid-to-high-speed text animation laser of >30Kpps. light.
3. The actual effect of voice control
Many lights now have a “voice control” function, as do laser lights. “Voice control” refers to a very simple volume that can trigger the play function of the light. Generally, the effect produced is very few and single.
4. Artistic effects of text animation
The text animation laser light should have the artistic effect of a “broken pen” so that when placing text, there is a laser connection between the strokes of the same word or two texts. There is no “broken pen” laserlys, and the animation art effect is basically absent, so the text or animation is very distorted.
5. “Multiple laser-pattern special effects”
If the laser light has “multi-pattern special effects”, the content it presents will be more perfect and exquisite, and it can cast a variety of rich combination effects.
6. “DMX512” intelligent programming
The laser light with “DMX512” intelligent programming has very rich effects and many patterns. It can combine the effect of the laser with the stage scene so that the laser light perfectly presents its lighting effects in each scene.
7. The degree of dust-proof sealing of the laser light
The optical reflective lens in the laser light affects its brightness and reflection efficiency. If it is not carefully packaged and dust-proof measures are not taken, it is easy to be contaminated by dust and oil, contaminate the lens, and finally reduce the reflection efficiency and brightness, and the effect is not good. obvious. Frequent cleaning of the lens will cause damage to the reflective film. Therefore, it is necessary to purchase a laser lamp with good dust-proof measures and observe whether there is a dust-proof glass in its laser output port when purchasing.
Also, pay attention to regular inspections.
