| Although the first incandescent lamps having reflector-shaped bulbs were created in the 1890s, the available technologies for the production of reflective coatings, as well as the understanding of optics and correct profiling of the reflector surface, made the early lamps quite ineffective and they were rarely used. The modern generation of reflector lamps did not emerge until the 1930s when a new technique for creating mirror coatings was developed, combined with the parallel introduction of scientifically-designed bulb shapes to optimise the optical performance. Later developments in glass forming processes enabled a significant performance increase with the introduction of pressing instead of blow-moulding techniques. Some of the key steps in the evolution of reflector incandescent lamps are featured on this page. |
