Embodiment Construction

[0043] Reference will now be made in detail to the embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numerals are used to refer to the same components or parts. For reference, Cartesian coordinates are shown in some of the drawings.

[0044] figure 1 is a top view of an example of an optically coupled optical system (referred to as "the system") 10 in accordance with the present invention. figure 2 yes figure 1 A perspective view of the light-coupling optical system. The system 10 generally includes a transparent plate 20, a light diffusing fiber 50 operatively disposed adjacent to the transparent plate, and a light source 100 optically coupled to the light diffusing fiber. In an example, light source 100 includes at least one light emitting diode (LED) or at least one diode laser. Light source 100 emits light 102, which in one example has a wavelength ranging from 350nm to 1000nm, and in a...

Abstract

Systems and methods for coupling light to a transparent plate. The system includes a light source and a light diffusing fiber optically coupled to the light source. A light diffusing optical fiber has an inner core, a cladding, and a length, at least a portion of the inner core including randomly arranged holes configured to provide a substantially continuous light emission.

Description

[0001] Cross-references to related applications [0002] This application claims the benefit of priority to the following patent applications: U.S. Application Serial No. 13 / 094,221, filed April 26, 2011, and U.S. Application Serial No. 13 / 269,733, filed October 10, 2011, herein relied on their contents and are incorporated by reference in their entirety. technical field [0003] The present invention relates generally to coupling light into optical media, and more particularly to systems and methods for coupling light into transparent plates. Background technique [0004] Various electronic devices using flat panel displays are increasing. Such devices can range from the largest flat-screen televisions to the smallest handheld devices such as cell phones. [0005] In some types of flat panel displays, a light source provides the light needed to view the display. For example, in one type of liquid crystal display, the addressable liquid crystal display structure is backl...
