Installing lit boxes inside the top canopy of wall display cases or in the bottom cabinet of jewelry showcases has primarily a promotional purpose. In both cases a cut off will be done on the front face of the cabinet. It will be covered with an acrylic sheet cut to size. On the acrylic sheet the logo, company name, collection name of the represented company will be silk screened or in printed. The look of the glass display showcase will be enhanced with the installation of light tubes inside the cabinet to brighten the representation on the acrylic sheet. Brands, corporations, convention centers, event planners will often order glass display cases with light boxes inserted from glass display cases manufacturers. It is a compact and effective way to advertise any new products, event or occasion.
