  • A LENS PLATE AND A LIGHTING DEVICE HAVING THE LENS PLATE
    Publication number: 20230324028
    Abstract: A lens plate has an array of convex lenses each having a top portion which forms a light input surface for facing a light source and a base which forms a light exit surface. Each convex lens has a height H and a diameter D at the base, wherein H/D>0.85. The lens plate for example has a height from the base of the convex lenses to the top portions in the range 1.5 mm to 5 mm.

  • Electrical generation of return-to-zero (RZ) data pattern with flexible duty cycle adjustment for optical transmission
    Patent number: 7751719
    Abstract: An electrical return to zero (RZ) encoder converts non-return to zero (NRZ) data, into of RZ data patterns with a flexibility for duty cycle adjustment so that any RZ data pattern may be provided for a specific application's need. A duty cycle of>50% or<50% may be achieved by selecting between a clock signal or its complement and adjusting its delay.
