An integral lamp (84) for producing a spectral light distribution substantially identical in uniformity to the spectral light distribution of a desired daylight with a color temperature of from about 3250 to about 10,000 degrees Kelvin throughout the entire visible light spectrum from about 380 to about 780 nanometers. The lamp includes a coating on at least one of its surfaces having a transmittance level in substantial accordance with the formula D(L)=[O(L)-F(L)xS(L)]/[S(L)x{1-F(L)}], wherein: O(L) is the desired daylight spectral output, D(L) is the spectral transmission of the coating, S(L) is the spectral output of the source, and F(L) is the likelihood of the reflected wavelength of light missing the element, and F(L) defined by the equation F(L)=[-1.7333x10-4 - 9.3333x10-7K][L4xR]1 + [-4.7708x10-1 + 2.3167x10-5K[L4xR]2, wherein: L is wavelength in nanometers, R is a constant equal to 5595581692912, and K is the desired daylight color temperature in degrees Kelvin. |
