Lightbox

A lightbox is a self-contained, illuminated display device, typically rectangular, used to backlight transparent or translucent materials for viewing or display. It provides uniform and even illumination across its surface, enhancing the clarity and vibrancy of the displayed content. Lightboxes are commonly used for viewing photographic slides, negatives, and x-rays, and also serve as display units for advertising, artwork, and graphic designs. They utilize various light sources, including fluorescent lamps, LEDs, and electroluminescent panels, to achieve optimal brightness and color rendering. Modern lightboxes often incorporate features like dimming controls and color temperature adjustments to customize the viewing experience. The construction typically consists of a light-diffusing panel, a light source, and a supporting frame.
