Claims
- 1. A light source apparatus that emits a visible light having a plurality of colors comprising:a light source emitting a visible light; a transparent envelope having an exterior surface and an interior surface enclosing said light source; at least one dichroic filter partially carried on said envelope surface wherein said dichroic filter is characterized as a reflector for reflecting a desired band of wavelengths of visible light and to transmit all other wavelengths; said desired band of wavelengths reflected from said dichroic filter exit via said transparent envelope while transmitting all said other wavelengths through said transparent envelope via said dichroic filter whereby the total amount of visible light is emitted as separate colors.
- 2. The light source apparatus defined in claim 1 including:a light reflector disposed on said envelope surface in spaced-apart relationship with respect to said dichroic filter for reflecting visible light of all bands of wavelengths; and said light source separating said reflector and said dichroic filter.
- 3. The light source apparatus defined in claim 2 wherein:said dichroic filter is linear having a plurality of portions side-by-side wherein each portion is capable of transmitting and/or reflecting bands of wavelengths therethrough.
- 4. The light source apparatus defined in claim 1 wherein:multiple dichroic filters are enclosed by said envelope; and a light reflector carried in said envelope separated from said dichroic filters by said light source.
- 5. The light source apparatus defined in claim 4 wherein:each of said multiple dichroic filters passes a different color band of wavelengths; and said multiple dichroic filters being arranged in a side-by-side series so as to receive visible light from said light source and from said light reflector.
- 6. The light source apparatus defined in claim 4 including:a second envelope enclosing said light source; said multiple dichroic filters being carried on said second envelope; and said reflector carried on said surface of said first mentioned envelope.
