<P>PROBLEM TO BE SOLVED: To provide more sufficient control of a light output from a panel assembly and more efficient use of light, so as to be adapted for specific applications. <P>SOLUTION: A light-emitting panel assembly includes a light-emitting panel member 22 having a uniform or variable pattern of light-extracting deformities 109 of well-defined shapes in or on one or more surfaces of the light-emitting panel 22. The size and shape as well as the depth and angular orientation and position or location of the light emission of the light-extracting deformities 109 may vary along a length and/or a width of a panel surface area to obtain a desired light output distribution from the panel surface area. A focused light source 3 may be insert molded or cast within a light transition area of the light-emitting panel to focus the light on an input surface of the light transition area with predetermined ray angles to fit a particular application. Therefore, the assembly can be used for a backlight of a liquid crystal display (LCD) or other indicators or all types of illumination, lighting for decoration and exhibition, lighting for vehicles, lighting for dentistries, lighting for phototherapy and other medical uses, membrane switch lighting, as well as lighting for sporting goods and clothing. <P>COPYRIGHT: (C)2010,JPO&INPIT |
