Abstract
A lamp assembly comprised of a waterproof casing, a lamp disposed within the casing, and a source of electrical current electrically connected to the lamp, from the source to the lamp. The lamp, when operated with a 12 volt power supply, consumes less than 40 watts The preferred lamp used in the assembly is described and claimed in U.S. Pat. No. 5,418,419.
Claims31
A lamp assembly comprised of a waterproof casing, a lamp disposed within said casing, and a source of electrical current electrically connected to said lamp, from said source to said lamp, wherein:
- (a) said lamp, when operate with a 12 volt power supply, consumes less than 40 watts,
- (b) said lamp is an integral lamp for producing a spectral light distribution which is substantially identical in uniformity to the spectral light distribution of a desired daylight throughout the entire visible light spectrum from about 400 to about 700 nanometers,
- (c) said lamp comprises a filament which, when excited by electrical energy, emits radiant energy throughout the entire visible spectrum with wavelengths (1) from about 400 to about 700 nanometers, at non-uniform levels of radiant energy across the visible spectrum,
- (d) said lamp is comprised a reflector body with a surface to intercept and reflect such visible spectrum radiant energy, said filament being positioned within said reflector so that at least 50 percent of sa d visible spectrum radiant energy is directed towards said reflector surface, and
- (e) said lamp is comprised of a filter coating on the surface of the reflector body, with a reflectance level to reflect radiation of every wavelength of the entire said visible spectrum radiant energy directed towards said reflector surface, and which when combined with the radiance of the visible spectrum radiant energy of the filament not directed towards said reflector surface produces a total usable visible light of relatively uniform radiance throughout every wavelength of the visible spectrum in substantial accordance with the formula:
- R(1)=[D(1)−[S(1)×(1−X)]]/[S(1)×X] wherein R(1) is the reflectance of the reflector coating for said wavelength, D(1) is the radiance of said wavelength for the daylight color temperature, S(1) is the total radiance of a d filament at said wavelength, and X is the percentage of visible spectrum radiant energy directed towards said reflector surface.
