摘要： 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.

摘要翻译： 提供一种光纤光源，其中具有短波和窄波段波长的输入光被转换/变换成具有高强度输出功率的多波段可见白光。 新的光源包括至少一个均化光导元件和至少一个光致发光元件。 它也可以包括至少一个输入元件和光纤。 所有或一些元件可以被集成到光波导中。 在一些实施例中，所述至少一个输入元件增加从光源到光纤光源的至少一个均化光导元件部件的光传输效率。 该至少一个光致发光元件可以是像线或表面那样的点或扩展形式。 光纤光源输出光束也可以包含输入光线的波长，其又可以来自光纤激光器。 在操作中，输入射线穿过至少一个均化光导元件并且照射存在于装置的预选位置中的至少一个光致发光元件，以在期望的目标处引起大面积或宽敞的照明。 这个信息源可以作为一个信息来源，通过光线调制来传递信息，这对于肉眼来说并不明显。 信息从光源发送到信息接收器，技术设备如智能手机，电视显示器或其他设备，这些设备可以取代LAN或WL​​AN网络的常见用途。 这里可以使用已知的发光检测器来有效地收集其光学形式的信息并将其引导至合适的光电检测器。 这使得自由空间光信息传输成为可能，特别是在使用传输光纤的传统基础设施难以建立的地区。
