Ultra slim crystal light box is a high-tech products which is developed through light guide technology and nano materials, it is best to replace traditional LED light box products.
Compared with the traditional light box, ultra slim led light box has the following advantages:
* Ultra-thin and beautiful, exquisite appearance TAG Heuer;
* Energy efficient, safe and reliable circuit;
* Soft light, brightness uniformity pleasing;
* Simple installation and easy maintenance for painting;
* Light board durable, stable and reliable quality.
* Crystal Light Box uses side of the optical design, light uniformity;
The crystal light boxes has been adopted optical-grade acrylic material, so it has niceappearance, super thin. Its thickness is only 8mm-10mm
* More secure and energy saving, longer life, easy to change the picture and install
The main structure of crystal light boxes:
<1>The design principle of LGP (light guide platel):Currently, the widely used light guide panel is developed from the concept of our usual LCD display of laptop that we see. It adopt spectral theory and laser engraving or digital printing technology, produced at a constant temperature and humidity, dust-free environment conditions It has the features of ultra slim and super bright, optical uniformity, energy saving and environmental protection, no dark areas, and easy installation and maintenance. Currently the maximum width of the light guide plate up to 1500mm, length up to
3000mm, and the thickness of the thinnest long is 2mm.,
In order to ensure the brightness, the larger its size, the more thick it should increase At the same time the effect of guide light would become more poor. However ,the most thickness of the light guide plate is not more than 20mm
<2> The astigmatism principle of Light guide panel: the light guide panel is pressed into the surface of a smooth plate
Block by using propylene ,through the way of injection molding, and then covered with a high reflectivity material not absorbing the light. On the bottom surface of the acrylic panel, it would be printed with a round or square screen printing point, so that diffuse the light. When light shines diffusion point, the light will reflect in all directions, and then
After the destruction of positive reflection conditions emitted by the light guide plate. To make uniform light, you must use all kinds o diffusion points which has different density and sizes( The difference of density and sizes can ensure the reflected light the same reflect chance in all directions).
The use of reflective panel in the light guide panel can reflect the light on the bottom back to light guide plate, in order to improve light utilization and increase the brightness degree
Although the production process in many kinds of light guide plate is different, they are using the principle of reflection and scattering of light.
The using scope of crystal led light box:
* Wedding sand photography, home decorative painting;
* Indoor and outdoor signs;
* Large-scale exhibition project or activities exhibitions;
*hopping malls, banks, hotels, restaurants, and other wall decoration publicity;
*Airports, subways, railway stations, bus stations and other advertising media;
*Gifts and crafts
