摘要: A LED package includes an LED that emits excitation light and an optically transparent body. A layer of phosphor material is positioned to receive the excitation light and is disposed on or in the optically transparent body. The phosphor material emits visible light when illuminated with the excitation light. A reflective polarizer layer is disposed on or in the optically transparent body and is positioned to receive the emitted visible light.

摘要: An optical film is provided which comprises a disperse phase of polymeric particles disposed within a continuous birefringent matrix. The film is oriented, typically by stretching, in one or more directions. The size and shape of the disperse phase particles, the volume fraction of the disperse phase, the film thickness, and the amount of orientation are chosen to attain a desired degree of diffuse reflection and total transmission of electromagnetic radiation of a desired wavelength in the resulting film.

摘要: A transflector is described which increases efficiency and brightness under both ambient and supplemental lighting conditions in visual display applications. In one embodiment, the transflector includes a reflective polarizing element that reflects one polarization of light and transmits the other. In an alternate embodiment, the transflector includes a reflective polarizing element and a diffusing element such that the transflector diffusely reflects light of one polarization and transmits the other. The transflector is useful for both reflective and transflective liquid crystal displays.

摘要: Hand-holdable toy light tube comprising a handle, a light source and a tube of color shifting film. The light source is preferably disposed within an end of the handle. The tube of color shifting film extends from the end of the handle. During use, light from the light source interacts with the tube of color shifting film, producing a brilliant colored effect. Movement of the handle and thus of the tube of color shifting film produces multiple colors.
