摘要: An electric make-up mirror having light sources which provide substantially uniform energy output through most of the visible region, when used in conjunction with filters will simulate specific lighting conditions such as daylight, office (fluorescent), home and evening (incandescent). The are comprised special lamps a unique degree flexibility that various may be simulated minimal loss energy. is provided two matching sources, filter assemblies disposed on opposite sides mirror. adjusted by single control mounted for synchronous selection from each assemblies. assembly, interposed between user, selectively vary spectral distribution transmitted so to ordinary fluorescent incandescent light. allows user select illumination approximating type under expects seen.
