The paper deals with physical and chemical characteristics of a new reflector produced by physical vapor deposition method and highly efficient floodlights developed as an application of the new reflector.
The new reflector surface is composed of three layers; aluminum substrate is coated with special heat resistance resin to get the smooth surface, on which super pure aluminum (99. 99%) and silica glass are deposited in turn to get high reflectance and durability. It is found from the experiments that the new reflector takes some advantages over the conventional anodized aluminum reflector, especially in reflection properties and anticorrosion.
As a result, highly efficient floodlights for. 1, 000-watt HID lamps have been developed.
