  • Patent number: 8733961
    Abstract: A light bar for illuminating a surface that is substantially perpendicular to the light bar includes an elongated housing extending along an edge of the surface to be illuminated. The housing has a wall adjacent the surface to be illuminated, and at least portions of that wall are transparent. A series of light emitting diodes (LEDs) are mounted within the housing and spaced along the length of the housing for illuminating the surface, and a connector couples the LEDs to an electrical power source for energizing the LEDs to produce light that illuminates the surface.

  • Patent number: 8729498
    Abstract: High throughput UV curing systems for mass curing of a plurality of articles without compromising product quality. The systems comprise a plurality of UV banks, each bank comprising a plurality of fluorescent UV lamps, thereby creating a consistent blanket of UV energy. A plurality of coated articles are positioned between pairs of banks such that the UV exposure or dosage is evenly distributed for each article. The fluorescent UV lamps use proportionally lower energy per unit and generate less heat than standard UV lamps, while sufficiently curing the coating on each article. Throughput is increased compared to currently available systems because the systems are easier to maintain requiring less downtime, can cure significantly more articles per cycle, and reduce the number of rejected products.

  • Patent number: 8702268
    Abstract: A recessed lighting fixture which utilizes a fluorescent light source. The fluorescent lights are shrouded by a diffuser lens basket so that light from the fluorescent bulbs shining through the diffuser is dispersed to reduce glare and visibility of the source of light. It is an object of the present invention to provide a fluorescent recessed lighting fixture which has the illumination from the fluorescent bulbs shining through a diffuser. It is also an object of the present invention to provide a single driver or ballast within the body of the fixture where access can only be gained from below the fixture.

  • Patent number: 8678611
    Abstract: A light emitting diode (LED) lamp includes a tube having a transparent first section and an opaque second section. An LED disposed inside of the tube. The second section is has an inner surface having a light diffusive surface so that the LED light is diffusively reflected. The LED is disposed so that a total amount of direct light from the LED to the first section is smaller than a total amount of indirect light that is incident on the first section as a result of being reflected by the second section (i.e., scattered or diffused light). The LED is disposed so that a light axis of the LED points toward the inner surface of the second section.
