DJ Laser Light Specific models have
Stage laser light is a music rhythm can automatically play with a variety of laser beam, laser pattern, laser text laser products, is the stage, dance halls, bars, KTV, home party commonly used to increase the atmosphere of a new product, the specific model There are: monochromatic laser light, two-color / three-color / full-color laser light, gypsum laser light, firefly laser light, animated laser light, the number of laser head can also be divided into: single-shot laser, Cast / four cast / five cast laser light. Laser power also the size of the power, the greater the power, laser effects can take care of the larger space, the price is more expensive.
The material used to make the model with a laser lamp is a liquid photosensitive resin which, after absorbing the energy of the laser light in the ultraviolet band, solidifies and changes into a solid material. Make the model to be made into a program and enter it into a computer. The laser light beam from the laser light is controlled by a computer to control the optical path system, so that it scans on the model material, where the laser beam is, and the original material is solidified. Laser light beam in the computer under the command of the scoring scoring, the photosensitive polymer material layer by layer curing, accurate accumulation into the sample, to create a model. So, with this approach to create a model, fast, made out of the model and refined. The technology has been widely used in aerospace, electronics, automotive and other industrial fields. Laser light machine is a laser to scan the film to produce graphics, and its principle as the TV picture tube in the electron gun scanning the same fluorescent material on the screen. First, the printed circuit board is mapped to a large memory array, and then the laser beam is opened or closed (modulated) according to the value of the corresponding cell in the memory array to obtain the desired process film.
Laser light machine with laser light source, easy to focus, energy concentration, etc., on the instant fast film exposure is very favorable, drawing the film edge neat, contrast, not virtual light. Exposure with scanning, no matter how much density, can be completed in the shortest time exposure, drawing a film just a few minutes. So become the mainstream of today's light painting industry.
The laser light of the laser light machine uses gas lasers such as argon, helium and neon. Gas lasers light source strength but life is limited, about 6000 ~ 10000h, so use more than a year need to replace the light source. Now some manufacturers of light-painted machine using a semiconductor laser as a light source, but the production of high-power semiconductor lasers is not very mature. According to the structure of laser light machine, can be divided into internal cylinder (Internal Drum) and external drum (External Drum).
(1) within the cylinder laser light to the United States Gerber company developed crescent series of laser light machine as the representative of the film by vacuum adsorption in a drum-shaped wall. Argon hydrogen lasers emit blue lasers, optically selected by the electronic shutter and beam intensifier, and then by two 45. The reflector is reflected to the high-speed rotation (200r / s) of the diagonal mirror, and then reflected to the film. Due to the high speed rotation of the oblique mirror, the light spot reflected on the backsheet forms a continuous line. The mirror is rotated at a high speed and moved horizontally and horizontally at a speed of 12 cm / ml n with its base "Spinning Miiror". Therefore, the spacing between each light is only 10btm, the formation of strip scanning exposure. At the same time, this laser light in the 200 million times per second under the electronic shutter control, open and close the action to complete the negative and positive exposure.
