  • Patent number: 7278775
    Abstract: A light guide containing substantially aligned non-spherical particles provides more efficient control of light scattering. One or more regions containing ellipsoidal particles may be used and the particle sizes may vary between 2 and 100 microns in the smaller dimension. The light scattering regions may be substantially orthogonal in their axis of alignment. Alternatively, one or more asymmetrically scattering films can be used in combination with a backlight light guide and a reflector to produce an efficient backlight system. The light guides may be manufactured by embossing, stamping, or compression molding a light guide in a suitable light guide material containing asymmetric particles substantially aligned in one direction. The light scattering light guide or non-scattering light guide may be used with one or more light sources, collimating films or symmetric or asymmetric scattering films.

  • Patent number: 7213942
    Abstract: A single-chip integrated LED particularly adapted for direct use with a high voltage AC power comprises a plurality of series-connected LEDs arranged in two arrays and flip chip bonded to a transparent substrate. The opposite polarities of the arrays are connected together and then connected to the AC power source. During the positive half of the AC cycle, one array of LEDs is forward biased and energized, while the other array is reverse biased. During the negative half of the AC cycle, the other array of LEDs is forward biased and thus energized, while the first array is reverse biased and thus not energized. The arrays are alternately energized and de-energized at the frequency of the AC power source, and thus the single-chip integrated LED always appears to be energized.
