专利汇可以提供Composite light source专利检索，专利查询，专利分析的服务。并且A composite lamp having relatively high efficacy and improved color richness and warmth. The lamp is comprised of a mercury or a metal halide lamp and a tungsten halogen lamp which are located in a common housing. The mercury or metal halide lamp is of relatively high efficacy and relatively high lumen output whereas the tungsten halogen lamp is of relatively lower efficacy and lower lumen output and is used primarily to improve the warmth and richness of the light output of the composite lamp. The tungsten halogen lamp is mounted directly beneath the mercury lamp and is physically much smaller so that only a minimal amount of the lumen output of the mercury lamp is obscured.，下面是Composite light source专利的具体信息内容。

权利要求

1. A COLOR MODULATABLE COMPOSITE LIGHT SOURCE COMPRISING A MERCURY LAMP AND AN INHERENTLY LOWER EFFICACY TUNGSTEN HALOGEN LAMP HAVING A RATED BOLTAGE, A HOUSING IN WHICH SAID LAMPS ARE ENCLOSED AND WHICH INCLUDES AT LEAST A REFLECTOR FOR REFLECTING THE LIGHT EMITTED BY SAID LAMPS, SAID TUGSTEN HALOGEN LAMP BEING MOUNTED IN SAID HOUSING DIRECTLY BENEATH SAID MERCURY LAMP AND BEING SUBSTANTIALLY SMALLER IN PHYSICAL SIZE THAN SAID MERCURY LAMP SO THAT ITS OBSCURES ONLY A MINIMAL AMOUNT OF THE LUMEN OUTPUT OF SAID MERCURY LAMP, MEANS FOR SIMULTENEOUSLY SUPPLYING ELECTRICAL ENERGY TO SAID LAMPS IN RESPECTIVE AMOUNTS TO CAUSE SAID MERCURY LAMP TO HAVE A SUBSTANTIALLY GREATER LUMEN OUTPUT THAN SAID TUNGSTEN HALOGEN LAMP, AND COLOR MODULATOR MEANS COMPRISING A MANUALLY OPERABLE MEANS FOR VARYING THE AMOUNT OF ELECTRICAL ENERGY FED TO SAID TUNGSTEN HALOGEN LAMP TO VARY THE COLOR OUTPUT OF THE LIGHT SOURCE.

2. A color modulatable composite light source comprising a metal halide lamp and an inhereNtly lower efficacy tungsten halogen lamp having a rated voltage, a housing in which said lamps are enclosed and which includes at least a reflector for reflecting the light emitted by said lamps, said tungsten halogen lamp being mounted in said housing directly beneath said metal halide lamp and being substantially smaller in physical size than said metal halide lamp so that it obscures only a minimal amount of the lumen output of said metal halide lamp, means for simultaneously supplying electrical energy to said lamps in respective amounts to cause said metal halide lamp to have a substantially greater lumen output than said tungsten halogen lamp, and color modulator means comprising a manually operable means for varying the amount of electrical energy fed to said tungsten halogen lamp to vary the color output of the light source.
