    Abstract: The present invention relates to regulated power supplies or ballasts integrated with an LED light source. The invention provides a power factor correction scheme producing a greater circuit power factor and improved frequency spectrum characteristics, in which a voltage corresponding to the instantaneous inductor current is sampled and compared to a scaled sample of the rectified input AC line voltage. The line voltage sample modulates the inductor peak charge current in the envelope of the rectified AC voltage waveform. This drives the LED output voltage at a frequency of twice the input line voltage frequency, such that no flicker is perceived in the light output because the persistence in LED phosphor assists in averaging the flux output.

    Abstract: A window lighting system for a building structure curtain wall is provided with a housing sized to be received upon a structural member, with an opening facing the window. A refracting lens is mounted adjacent the opening. A plurality of longitudinally spaced discrete light sources are positioned in the housing, each oriented towards the refracting lens such that the light is conveyed to the refracting lens and subsequently out of the housing opening for illuminating the window. A lighting system is provided with the housing sized to extend along the window upon a cover of a structural member between a pair of sequential structure members. A lighting system cover is supported by the housing for concealing the light source and providing an ornamental appearance similar to that of the cover of the underlying structural member without obfuscating an ornamental appearance of the window and the structure members.

  • Publication number: 20100207543
    Abstract: A current-driven load such as LEDs or laser diodes is driven by a current driver having a two stages (or phases), the summed outputs of which have ripple which is forced to be out-of-phase with one another. In analog embodiments, an output (ripple or switching) of a master stage hysteresis controller is phase-shifted and scaled, and modulates the input of a slave stage hysteresis controller so that the slave stage pulls into a ripple-canceling phase. In a digital embodiment, a faster of the two phases is designated “master”, maximum and minimum thresholds are set, and the slave phase's on time is based on a previous cycle's slave phase ON time, the master stage OFF time and an offset. The slave controller preferentially “locks” to the anti-phase of the master stage (or phase) and the ripple current at the summed output substantially cancels.

    Abstract: A system and method for powering a light-emitting element in an illumination device includes a DC power supply with the light-emitting element coupled across a positive output terminal and a negative output terminal of the DC power supply. A switching element is coupled between the light-emitting element and the negative output terminal. An average current value across the light-emitting element is measured each time the switching element is turned on. A control circuit generates a PWM signal having a pulse width determined based on the calculated average current value and a predetermined target value, and applies the PWM signal to drive the switching element on and off in accordance with the determined pulse width, and a current is generated across the light-emitting element.

  • Publication number: 20100207549
    Abstract: Visible and infrared light sources on silicon that have several attractive properties with respect to integrated optics. First, the devices are operational at room temperature and strictly require no thermal processing in their synthesis (although low temperature annealing can be used to form Ohmic contacts). These devices could therefore be included at any stage of chip fabrication. The special ease of synthesis of these silicon LEDs enables simple fabrication of surface structures such as patterned emitters and photonic crystal surfaces that enhance light emission in the forward direction. The LEDs are color-switchable—by reversing the current one can switch from infrared emission to visible emission. The lifetime of the luminescence is much shorter than the standard carrier recombination time in silicon, suggesting direct modulation of the emitted light.

    Abstract: An energy recovery circuit for a plasma display panel (PDP) according to the present invention includes an energy recovery unit recovering and storing energy from the PDP; and a switching stabilizing unit electrically connected to the energy recovery unit to stabilize switching of a sustain discharge pulse applied to the PDP. The switching stabilization unit may include one diode, two switches and one capacitor for energy recovery, or include two switches and an external input voltage source that is an external voltage supply. According to the present invention, the difference of voltages applied to both drain and source terminals of a switch SW2 for applying a sustain discharge voltage Vsus is minimized at the time when the switch SW2 is switched, so that switching can be stabilized by preventing hard switching from being generated when the sustain discharge voltage is applied to a panel.
