摘要： A light source having a flexible light-generating module that includes a flexible circuit carrier, a plurality of light emitting dies, and a cover layer is disclosed. The flexible circuit carrier includes a sheet of flexible material having electrically conducting traces. The light emitting dies are electrically connected to the electrically conducting traces. The cover layer is constructed from a transparent, flexible material and covers the light emitting dies. The light-generating module can be attached to various surfaces to provide a light source that is non-planar as well as to surfaces that are piecewise planar. These more complex light sources can include garments that generate complex light patterns to call attention to the wearer and three-dimensional light sources. The light sources also provide improved heat-conduction and can be used to create non-rectangular back lights for displays.

摘要： An encoder having a carrier that passes through an opening in a mounting body is disclosed. The carrier includes an encoding region having a plurality of clear and opaque regions, the carrier having first and second surfaces. The clear and opaque regions of the carrier pass through the opening in the mounting body when the carrier moves relative to the mounting body. A light emitter generates a light signal that passes through the carrier, the light emitter being located adjacent to the first side of the carrier and separated therefrom. A light reflector is attached to the mounting body at a position such that the light reflector directs the light signal through the second surface of the carrier where a photodetector measures light leaving the first surface of the carrier when one of the clear regions passes through the light signal.
