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, laser lights can often create a magical and dreamy atmosphere. When purchasing 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!when you purchase a laser demonstration product, you must pay attention to whether this 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 medium-high-speed text animation laser light.
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. The effect is usually The "voice control" effect is incomparable.
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 area, etc., the beam is directed into the distance, and a bright green light appears in the air, which is very dazzling. The beam can swing up and down, left and right, and its magical and gorgeous face can be enjoyed within a radius of several kilometers.
