LED light bars and beads.

at present, most advertising light boxes use LED light bars as the main light source, and the old-fashioned light tubes have been gradually eliminated, because the old-fashioned light tubes emit uneven light and are prone to ribs, which makes the advertising effect of light boxes discounted. At present, the light source of advertising light boxes mostly adopts LED light bars or LED light beads, which not only highlights but also saves energy. LED light bars are generally divided into LED backlight and LED side light sources according to different light boxes. And a good LED lamp must be inseparable from good chips, heat dissipation substrates and electronic components, because they will affect the light attenuation and life of LED lamps.

Single-sided light boxes generally use backlight, and the light bars or single light beads are fixed on the bottom plate of the light box at a certain distance, which is not affected by the size of the light box. It is also necessary to consider whether the light box is installed indoors or outdoors to choose whether the light bar is waterproof or not.

Extended information:

Double-sided light boxes generally use side light sources, and light bars or beads can be installed on the four sides of the aluminum frame of the light box at a certain distance, which can well evenly light the pictures of both light boxes. However, due to the influence of light box area, it is generally not recommended to use side light source for light boxes with too large area, for fear that uneven illumination will affect the publicity effect.

Therefore, if the light box is used for a long time, it is recommended to buy a light source with quality assurance when selecting the light, because the light source is also a part of the light box, which will affect the advertising effect of the light box at any time.
