Title: Energy-efficient incandescent lamp. Final report

Abstract

The status of the Energy Efficient Light Bulb (EELB) development at the beginning of the subcontract was characterized by a newly introduced lamp construction based on an optimum optical quality envelope consisting of two hemispheres or hemi-ellipsoids bonded together. Considerable progress was made concerning the output of the continuous process heat mirror coating machine, the reproducibility of the film characteristics, and the durability of the coating over long periods of lamp operation. The bonding assembly processes were improved to the point where they are suitable for full mechanization and high speed production. A new concept for dimensioning the required compact and mechanically stable filaments was introduced by using diodes in series that reduce the effective operating voltage to 83 volts. This has led to filament designs of greater stability and greater compactness than any obtained before. The efficacy and energy saving data of the prototype lamps delivered at the end of the subcontract were close to the target values established at the beginning.
