Abstract

PURPOSE:To develop a reflector without glaring by forming an org. polymer film on the surface of the reflector of a floodlight and then forming an Al vapor-deposited film and a protective film. CONSTITUTION:The surface of the reflector of a floodlight is cleaned, an org. polymer film of styrene or silicone is formed by thermally decomposing the raw gas. Al is then vapor-deposited on the surface of the film by vacuum deposition, sputtering, ion plating, etc., and then a thermosetting coating material or a UV-curing coating material is sprayed to form a protective film. The adhesion of the Al vapor-deposited film is improved as the reflector material, and an floodlight provided with a reflector with the glaring reduced is developed.
