What determine the brightness of ultra slim light boxesThe brightness is one of main technical parameters for ultra slim light boxes. It is customers' main requirement too. Because the brightness of ultra slim light boxes should be suitable with its display environment, the ultra slim light boxes can achieve eye-catching effect.
What determine the brightness of ultra slim light boxes?
1. LED strip.
The ultra slim light boxes usually us LED strip as its edge lighting source. And the light guide panel diffuses the light from the edge LED strip. That achieves the LED face lighting successfully from the LED dot lighting. So the brightness of LED strip will influence the brightness of ultra slim light box greatly. But the brightness of led strip is determined by the type of LED chip and the number of LED per meter. The LED chip will determine the LED power and light efficiency. The number of LED per meter is more, the brightness is higher. Certainly, the power consumption of ultra slim light boxes will become higher accordingly.
2. Light guide panel
The light guide panel diffuses the light from the edge LED strip. So its diffusing effect will determine the brightness of ultra slim light box. But the diffusing effect depends on the panel material and engraving technology of light guide panel. The panel material will determine the transmittance and durability of light guide panel. The engraving technology of light guide panel will determine the diffusing effect and lighting symmetry.
