Light emitting panel assemblies
EP 1163473 A1 (text from WO2000050807A1)
ABSTRACT
Light emitting panel assemblies include 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 emitting of the light extracting deformities (109) may vary along the length and/or 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. Molded supports may be provided on the panel member for supporting other parts or components in spaced relation therefrom.
