  • LED Lamp with Active Chamber Cooling
    Publication number: 20160305640
    Abstract: An LED lamp employing active cooling chambers is presented. The lamp features a housing having two active cooling chambers. One chamber, i.e. the first or cold chamber, contains an LED driver and one or more cooling fans, while the second chamber, i.e. the hot chamber, contains one or more LED modules secured to a heat sink. Fluid (air) communication between the two chambers is controlled by the one or more cooling fans. In operation, the fans draw ambient cooling air inside the cold chamber via air intake openings in the housing. The cooling air is then forced through a plurality of heat sink fins and heat transfer channels and exhausted from air exhaust openings in the housing.

  • Thin flat panel LED luminaire
    Patent number: 9470835
    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.

  • Low power bypass circuit for LED open circuit and reverse polarity protection
    Patent number: 9307610
    Abstract: A low power bypass circuit for use with a string of series-connected LEDs includes a semiconductor diode and resistor connected in series, which semiconductor diode and resistor combination become conductive upon the failure of an LED or upon the improper, reverse polarity connection of the string of series-connected LEDs to a power supply. When the semiconductor and resistor combination becomes conductive, a three-terminal gate-controlled semiconductor switching device becomes conductive, thereby bypassing the failed LED and protecting the integrity of the string of series-connected LEDs upon the improper reverse polarity connection of the string of series-connected LEDs to a power supply.
