    • PROBLEM TO BE SOLVED: To provide a device and method for driving an LED lamp which dynamically adjusts the number of LEDs in an LED string on the basis of a rectified voltage and more closely matches the overall ON-state voltage of the LED string to the rectified voltage, thus increasing utilization efficiency of electric energy.SOLUTION: This invention is for adjusting the numbers of LEDs in an LED string on the basis of a rectified AC voltage. An embodiment comprises a power module, an LED string, a current source and a controller. The LED string has multiple LEDs connected in series that form one major segment and multiple minor segments. The controller is connected to the current source and the LED string, and selectively shorts the LEDs in the minor segments.
    • 要解决的问题:提供一种用于驱动LED灯的装置和方法,其基于整流电压动态地调节LED串中的LED的数量,并且将LED串的总导通状态电压更接近地匹配到 整流电压,从而提高电能的利用效率。解决方案:本发明用于基于整流的AC电压来调节LED串的LED数量。 实施例包括功率模块,LED串,电流源和控制器。 LED串具有串联连接的多个LED,其形成一个主要部分和多个次要部分。 控制器连接到电流源和LED串,并选择性地短路次级段中的LED。

    • A rotary toilet bowl is disclosed. The rotary toilet bowl includes a water supply unit provided in a washstand; an upper rotative shaft securely coupled to the upper surface of the toilet bowl and rotatably coupled to a lower end of the washstand; a water supply pipe connected to the water supply unit of the washstand and extending to both the water jet discharge channel and the water supply channel of the toilet bowl through the upper rotative shaft; a lower rotative shaft coupled to the lower surface of the toilet bowl and rotatably coupled to the floor of the room; a drain path extending from the interior of the toilet bowl to a waste pipe installed under the floor through the lower rotative shaft; and a plurality of rollers each having a stopper and provided on the lower surface of the toilet bowl so that the toilet bowl can be rotated and stopped at a desired place. The toilet bowl can be rotated to protrude outwards when it is required to use the toilet bowl or rotated inwards to be retracted under the washstand.
