  • Publication number: 20180133629
    Abstract: A filtrating module has a reservoir and a plurality of nozzles. The reservoir has an inlet opening, an outlet opening, a plurality of partitions, and a plurality of chambers. The chambers are respectively formed between each two adjacent ones of the partitions. Lower parts of the chambers communicate with each other but upper parts of the chambers are isolated from each other. The nozzles are respectively mounted under the inlet opening of the reservoir and in the upper parts of the chambers. Openings of the nozzles face downward and are inclined toward the next chamber, but the nozzle in the last chamber is inclined toward the outlet opening. A filtrating device includes the filtrating modules connected to each other. Therefore, the working fluid can be jetted downward and inclined to the liquid level of the working fluid, and thus contaminants in air can be dissolved in the working fluid.

  • Patent number: 9504102
    Abstract: The present invention provides a light emitting device driver circuit and a control circuit and a control method thereof. The light emitting device driver circuit includes a power stage circuit, a feedback circuit, and a control circuit. The control circuit includes a comparison circuit, a hysteresis control circuit, and a bleeder circuit. The control circuit generates an analog control signal according to a rectified dimmer signal and an output signal, for controlling the power stage circuit to regulate an output current, which is supplied to a light emitting device circuit to determine its brightness. When the analog control signal decreases to a predetermined hysteresis low level, the light emitting device driver circuit operates in a cut-off mode wherein the bleeder circuit consumes a bleeder current so as to maintain the output current at a zero current, for keeping the light emitting device circuit OFF.
