What are the characteristics and applications of laser engraving machine in making ultra-thin light box?
Jan 09, 2019
The light guide plate ultra-thin light box is a kind of "energy saving, ultra-thin, convenient and safe" light box, which adopts the principle of spectral analysis and pulse laser engraving or digital printing technology to combine under the conditions of constant temperature, constant humidity and dust-free environment.
Features of laser engraving machine producing light guide plate:
1, save electricity,
More than 70% energy saving than traditional light box.
2. Low process cost
No screen version, no ink, no screen technology.
3. Easy operation
Any size of the light guide plate, just in the laser control system directly input the size can be one-time molding.
4. High brightness
The laser contactless production process is adopted to form a concave point (line) on the light guide material to destroy the direction of transmitted light on the light guide material, that is, the refracted light, while the silk screen light guide plate takes reflected light, so the laser light guide plate is brighter than the light guide plate in the general traditional silk screen manufacturing process.
5. Good uniformity
On the market at present most of the guide plate is not uniform, laser laser engraving machine of light guide plate in the control program to wring side method, so that it can be in the dark area to form the refraction point, obtain more refracted light, so that the plate overall brightness error is small, good uniformity. The direction of the light source for the surface light source, light more evenly, softer, more comfortable vision;
Long life
It is not affected by water and moisture, and its service life is 3.5 times. In general printing plate, as long as a touch of water will be dark, light attenuation is faster, some plate brightness will reduce about half a years. This is mainly printed board, is to rely on ink reflection, the ink in the light of high strength, will produce inevitable aging. The laser engraving is a molding of light guide plate, and no other chemical items on light material, so on to adapt to the environment was stronger than the traditional screen printing, longer service life.
