For example, in order to display food, restaurants, hotels, bars, shopping malls, supermarkets, canteens and beverage bars are usually equipped with food refrigerated display cabinets, and a light box is set on the top of the front of the food refrigerated display cabinet. The light box is made of transparent or translucent material, and the surface of the light box is affixed with spray-painted advertising patterns or directly printed advertising patterns. Light tubes are installed in the light box. At night, the light box is directly illuminated by light, making the advertising patterns on the light box vivid.
