Abstract
A colored lamp is emitting colored light of a given range of wavelengths and particularly useful for interior and exterior lighting, for luminous advertising, for street lighting, for signal lights and for decorations characterized by a source of light and an arrangement for absorbing a light wave spectrum which has a shorter wavelength than the given range and for emitting light with a longer wavelength due to photo-luminescence with the arrangements including at least one body provided with a luminescent substance for absorbing the light and emitting the luminescent light. The body may be formed by a container of liquid, a bundle of optical fibers or a solid member which acts as a light concentrator in such a manner that the incident light is collected and conducted by means of a photo-luminescent scattering and subsequent total reflection at the boundary surfaces of the body, with the luminescent light being emitted in specific output locations.
