LED Light Box light guide principle
 LED Light Box is how to achieve it? So thin a light box, but able to complete the thickness of up to dozens of cm light box to complete the light, and even the thinnest LED Light Box thinest 1cm, really can not be negotiated, how is this done?
At present the widely used light guide plate its design principle using the principle of spectral analysis and laser engraving or digital printing technology, with ultra-thin super bright, light guide uniform, energy saving, no dark area, simple and quick installation and maintenance of distinctive features. The maximum area of the current light guide plate 150 * 300 square centimeters, while the thinnest thickness of 0.2cm long. The larger the size, in order to ensure the brightness, the thickness should be a corresponding increase, and the effect of the corresponding light guide, the thickest light guide plate is not more than 2cm.
LED Light Box astigmatism principle: mainly through the light guide plate, the use of injection molding method of acrylic pressed into a smooth surface of the plate, and then in the acrylic plate with non-absorbable high reflectivity material, in the bottom of the plate with screen printing printed on a round Or square diffusion points, in order to diffuse the light. When the light hit the diffusion point, the light will be reflected in all directions, and then destroy the reflection conditions from the light guide plate positive injection. In order to make uniform light, you must use a variety of density, different sizes of diffusion points. The purpose of the reflector in the light guide plate is to reflect the light exposed from the bottom surface into the light guide plate in order to increase the use of light to increase the brightness.
In fact the market because of the size of LED Light Box is too large, there is no corresponding light guide plate to achieve the role of light guide, in order to solve this problem, LED Light Box was born.
The light emitted by the LED passes through the light guide plate through the optical action to form the surface light source, and then in the diffusion plate, the bright film emits a bright spot with uniform brightness. However, due to the use of diffusion plates and optical film will make the cost is too high, and excessive use will lead to increased wear and tear of the light, so basically through the optical design of the light guide - side of the backlight design to increase light guide plate uniformity The
Do light propagation, first of all have a light guide plate structure design. The light guide plate through the use of laser uniform point of the method, in the panel of the scattering network to change the side of the direction of light into the side, and then the formation of surface light source, but the need for acrylic material light guide plate, relative to other materials, light guide plate is difficult to achieve best effect. For this light guide plate design, brightness and uniformity are sufficient to meet the current application requirements, the obvious advantages.
 LED Light Box is the absolute leader in the market light box, as if the advent of plastic light boxes, LED Light Boxes not only solve the problem of large LED Light Boxes, and the success of the LED Light Box from the indoor to the outdoors, these two points is unparalleled, The following is its own advantages:
Superiority: is the primary condition for any product to capture the market.
1, ultra-thin beautiful: LED Light Box. Using light technology, frame reasonable structure, combined with energy-saving lamp, professional design is only 5-12CM thickness of light boxes, cost savings, simplified installation, the space requirements of the public channel, shopping , Supermarkets, airports, subway areas are widely used.
2, bright uniform light: no shadow brightness uniformity. Completely put an end to the traditional light box light and shade.
3, energy efficient: with the same area of the traditional light box than energy-saving more than 70%, only the year's electricity can be recovered light box investment.
4, long life: the average life expectancy of more than 50,000 hours, greatly saving maintenance costs. Company for three years
5, low temperature: ordinary lamp surface temperature is high, easy to produce indoor temperature rise, the surface temperature is only 38 degrees, will not burn the screen, maintaining a comfortable indoor temperature.
