  • Patent number: 7407617
    Abstract: A method of polymerizing by a free radical polymerization mechanism, product formed thereby, and apparatus for performing this method, are disclosed. The composition to be polymerized by the free radical polymerization mechanism is irradiated by a substantially constant radiation, the radiation being substantially without pulsation. The use of the substantially constant radiation without pulsation reduces premature termination of the polymerization. The substantially constant radiation can be the output of a lamp powered by a constant current, direct current power supply.

  • Publication number: 20040036423
    Abstract: A lamp assembly in accordance with the invention includes an electrodeless bulb (14) which is symmetrical about an axis (16) and which contains a light emissive fill which emits light when the bulb is excited by a RF electrical field coupled to the fill; an electrically conductive coupler (18) comprising a plurality of turns (20) which are symmetrical about an axis of the electrically conductive coupler, the turns defining a volume (19) that at least partially contains the bulb; and a conductor (26) connected to a center portion of the electrically conductive coupler with connection of the conductor to the electrically conductive coupler providing a fixing of the coupler relative to the bulb which, when the conductor is connected to a source of RF electrical potential, conducts a RF current producing a RF electrical potential on the electrically conductive coupler that produces the RF electrical field coupled to the light emissive fill.

  • Publication number: 20020079796
    Abstract: The invention is an optical device which reflects and absorbs light emitted from a light source with the reflected light being a selected wavelength range and the absorbed light being outside the selected wavelength range and a microwave excited discharge lamp. An optical device in accordance with the invention includes a light trap having a plurality of light absorbing surfaces, each light absorbing surface absorbing at least a part of incident light outside the selected wavelength range, the incident light striking an initial light absorbing area and being reflected from the initial light absorbing area to at least a secondary light absorbing area of one of the light absorbing surfaces, and a layer, fixed between the light trap and the light source, which passes the light outside the selected wavelength range to the light trap for absorption therein and which reflects the light within the selected wavelength range to a target area.
