<p>A lamp (10) for producing a spectral distribution which is substantially identical to daylight color temperature. The lamp contains a filament (18) which, when excited by electrical energy, emits radiant energy at least within the visible spectrum with wavelengths from about 400 to about 700 nanometers, a reflector body (12) with a surface (20) to intercept and reflect the visible spectrum radiant energy which is positioned within the reflector so that at least 50 percent of the visible spectrum radiant energy is directed towards the reflector surface, and a coating (36) on the surface of the reflector body from which the reflected radiance of each wavelength of visible spectrum radiant energy directed towards the reflector surface when combined with the visible spectrum radiant energy not directed towards the reflector surface produces a total light output in substantial accordance with a specified formula.</p> |
