发明名称 COMPONENTS AND METHODS FOR MANUFACTURING HOLLOW INTEGRATORS AND ANGLE CONVERTERS
摘要 The present invention describes an "L"-shaped sub-component (12) for a hollow reflective tube (8) used as an integrator and/or angle converter for an illumination system. Furthermore, this invention details methods of manufacturing such hollow reflective tubes (8) comprising (1) the steps of forming "L"-shaped sub-components substrates with or without self-alignment (11) and/or mounting features, (2) applying a reflective coating (40, 76) to the inside of said sub-components (3) and assembling said sub-components into hollow tubes (8). Preferably both sides of the "L"-shaped sub-components (12) have identical spectral and angular dependent coating performance. A particularly suitable method for manufacturing these sub-components (12) substrates is molding them in plastic and overcoating them with a base coating layer to enhance their specular reflectivity. One of the preferred methods of applying a highly reflective, environmentally stable enhanced Ag multi-layer stack is an ion assisted e-beam deposition process with the substrates oriented symmetrically towards the effective thin film material emission source. The high index layer material is preferably a metal oxide or ZnS and the low index material is preferably an oxide or a fluoride material.
