A fiber optic light source in which input light with short and narrow band wavelength is converted/transformed into multi-band visible white light with high intensity output power is provided. The new light source comprises at least one homogenizing light guide element, and at least one photoluminescence element. It may also comprise at least one input element and an optical fiber. All or some of the elements may be integrated into an optical waveguide. In some embodiments, the at least one input element increases light transfer efficiency from a ray source to the at least one homogenizing light guide element component of the fiber optic light source. The at least one photoluminescence element can be a point or an extended form like a line or surface. The fiber optic light source output beam may also contain the input ray wavelength, which in turn can be from a fiber optic laser. In operation, an input ray travels through at least one homogenizing light guide element and irradiates at least one photoluminescence element present in preselected positions of the device to cause large area or spacious illumination at a desired target. This source can be an information source to communicate information through light modulation not noticeable to the naked human eye. Information is sent from the optical light source to information receivers, technical devices like smart phones, TV-Displays, or other devices, which could replace the common use of LAN or WLAN networks. Here a known luminescent detector can be used to efficiently collect the information in its optical form and to lead it to a suitable photo detector. This enables free-space optical light information transfer especially in areas where traditional infrastructure using transmitting fibers is difficult to establish.
