RETRO-REFLECTION SHEET CAPABLE OF ENHANCING A RETRO-REFLECTION RATE BY FORMING A REFLECTING PART FOR REFLECTING A LIGHT, A RETRO-REFLECTOR USING THE SAME, AND AN OUTDOOR DISPLAY DEVICE

摘要

PURPOSE: A retro-reflection sheet, a retro-reflector using the same, and an outdoor display device are provided to reflect a light coming to a reflector by arranging one reflector having a predetermined volume inside a bead.;CONSTITUTION: A retro-reflection sheet includes a base layer(30), a reflecting part, and a bead layer. A first glass bead layer(10) and a first reflecting part(20) are formed in one surface of the base layer. A second glass bead layer(10') and a second reflecting part(20') are formed in the other surface of the base layer. The retro-reflection sheet efficiently reflects the light. The bead layer is made of glass bead of a minute ball shape. The glass bead is laminated by a laminating unit like a roller. The reflecting part is formed by uniformly coating silver using an aluminum paste on a top part of the bead layer, and is coated as proper thickness according to a diameter of the bead. The base layer is formed by a synthetic resin like PVC(PolyVinyl Chloride), PU(PolyUretan), and PE(Polyethylene).;COPYRIGHT KIPO 2010
