  • Patent number: 10048425
    Abstract: The invention described herein is a very thin flat panel LED luminaire, including a flat baseboard, a flat reflection panel, a flat acrylic panel, a flat diffusion panel, LED bar, and aluminum encasement frame which combines with the baseboard to form the chassis for the luminaire. The LED bar is placed along either or both sides of the stack. The acrylic panel is printed with a mesh-like mask pattern of dots in a pattern in which the density of the pattern is decreases the farther away from the LED bar the pattern is, differentially coupling the light from the point source LED bar from the reflection panel into the flat acrylic panel so that illumination across the luminaire is substantially uniform.

  • Patent number: 8891268
    Abstract: One embodiment of the invention relates to a switching control system for controlling an isolated power supply. The system includes a pulse-width modulation (PWM) switching controller configured to generate at least one primary switching signal having a first duty-cycle for activating at least one primary-side switch of the isolated power supply. A synchronous rectifier (SR) switching controller is configured to generate at least one SR switching signal having a second duty-cycle for activating at least one SR switch of the isolated power supply to conduct an output current through a secondary winding of a transformer and an output inductor to generate an output voltage, the second duty-cycle being independent of the first duty-cycle in a soft-start mode.

  • Publication number: 20140130982
    Abstract: A thin film processing apparatus assembles a substrate and an auxiliary plate tightly and the substrate is coated with a thin film whereon the auxiliary plate is situated. Since the substrate or the auxiliary plate is transparent for thermal radiation, the thin film heated by thermal radiation symmetrically in thickness direction will be available. Consequentially debonding, warping and cracking of thin film are thus prevented and outgassing from thin film is eliminated as well.

  • Publication number: 20140033786
    Abstract: A method for fabricating a metallic member includes providing a pre-forging mould. The pre-forging mould comprises an upper mould and a lower mould. The lower mould defines a pre-forging chamber, and a die cavity defined in a bottom surface of the pre-forging chamber. A metallic stock is placed above the die cavity, and the upper mould is moved toward the lower mould to forge the metallic stock, thereby forming a pre-formed body comprising a forging portion and a pre-forged base; annealing the pre-formed body; providing a forging mould to forge the pre-formed body, thereby obtaining a forged-body with a forged base thinner than that of the pre-forged base. Then the forged-body is milled to a desired size, and sandblasted, thereby obtaining the metallic member.

  • Patent number: 8576596
    Abstract: Various embodiments of the present invention provide voltage converters and methods for using such. As one example, a voltage converter is disclosed that includes a transformer with a first winding and a second winding. A voltage is applied to the first winding for a period that is followed by an OFF time. The voltage converter further includes an OFF time controller that is operable to adjust the OFF time based at least in part on a load current traversing the second winding.
