ABSTRACT:
A lamp assembly for providing light emission only over a selected portion of the visible spectrum which lamp assembly includes an electroluminescent means for emitting light over a predeterminable range of the visible spectrum which includes such selected portion. The lamp assembly further includes a first fluorescent means which absorbs light emitted by the electroluminescent means over another portion of the predeterminable range which does not include the selected portion thereof and emits the absorbed light over the desired selected portion. Additional light emitted by the electroluminescent means over still other portions of the visible spectrum can be prevented from emission from the lamp assembly by the use of a suitable filter therefor or by the use of an additional fluorescent means which absorbs such additional light and emits such absorbed light over the portion of the spectrum in which light is absorbed by the first fluorescent means.
