  • Display backlight with improved light coupling and mixing
    Publication number: 20070081360
    Abstract: A display backlight assembly providing improved optical coupling between a solid state light source and a display optical light guide. The assembly includes an optical coupler to couple the solid state light source and display optical light guide together. In addition, the optical coupler may include a light mixing element for improved mixing of the multi-colored or mono-chromatic light produced by the solid state light source.

  • Solid state LED bridge rectifier light engine
    Publication number: 20070069663
    Abstract: A solid-state light engine comprised of light emitting diodes (LEDs) configured into a bridge rectifier with a current limiting module coupled to the LED bridge rectifier. The light engine may be packaged for high temperature operation. Optionally, the LEDs comprise wavelength-converting phosphors with a persistence that is a multiple of the peak to peak current period, to smooth and mask ripple frequency pulsation of emitted light.
