Abstract
The invention discloses a shadowless lighting display system, comprising an aluminum alloy bracket and a shadowless lighting installation frame. The aluminum alloy bracket and the shadowless lighting installation frame are connected to each other by screws. The four frames of the shadowless lighting installation frame are connected to each other by a 90 ° angle code to form a rectangular shape. A load-bearing plate is placed on the top of the inner side of the shadowless lighting installation frame. The structure of the invention is scientific and reasonable, and it is safe and convenient to use, After the LED light source is incident on the acrylic light guide plate, it refracts parallel rays into vertically upward and downward rays through densely arranged 90 ° light refraction points. The upward refracted rays are then reflected into vertically downward rays by the reflective film attached to the acrylic light guide plate, making all the original parallel rays shine vertically downward. Under the action of densely arranged 90 ° light refraction points, the shadowless lighting board forms multi-point illumination, thereby achieving shadowless lighting function.
