摘要： A multi-channel LED driving system includes a power adapter, a rectifying and filtering unit, a plurality of LED strings, and a plurality of linear regulators, a CC/CV controller, an optically coupled isolator and a PWM controller. The CC/CV controller detects the conducting currents flowing though the LED strings and DC voltage source outputting from the rectifying and filtering unit, and provides voltage compensation of the power adaptor. In addition, the linear regulators slightly modulate the current difference between the LED strings to achieve current-sharing control, thus stabilize the illuminating brightness generating by the LED.

摘要： A seat cushion structure of chair is provided, in which a seat cushion body has a chamber provided on its upper end surface. The chamber has holders provided on its two opposite walls, and a plurality of spring steel wires have their two ends fixed on the holders provided on the opposite walls of the chamber so as to span across the chamber. An elastic pad covers correspondingly the upper end surface of the seat cushion body in such a manner that user, when sits on the elastic pad, enjoys comfortable and elastic feeling by the support of the elastic pad and the spring steel wires provided under the elastic pad. Furthermore, user's body heat can be dissipated through perforations provided on the elastic pad to the chamber of the seat cushion and thus to the outside, so as to enhance user's comfort.

摘要： A constricting member of a chair footrest ring is revealed. The constricting member is mainly a constricting sleeve with a hole mounted on a center thereof. A plurality of tapered-shaped mounting and fixing parts is disposed projectingly on an outer surface of the constricting sleeve, from top to bottom and expanded outward. At least one trench is also formed on the outer surface of the constricting sleeve. A positioning projective ring is projecting from and integrally formed on an outer edge on a top end of the constricting sleeve. The structure is simple so that the manufacturing cost is reduced and the assembling is more convenient and faster.

摘要： A constricting device for the footrest ring of a chair includes a constricting unit assembled between the center tube of a chair and the conical sleeve of a footrest ring. The constricting unit consists of a constricting main body and a fixing ring combining the constricting main body and the sleeve of the footrest ring. The constricting main body is a conical body fitted with the conical sleeve of the footrest ring, having its center bored with a fitting hole to be fitted around the center tube of the chair and its circumferential wall cut with plural openings. When the footrest ring is pressed downward by treading, the conical sleeve of the footrest ring will press the conical constricting main body and make it constricted to closely hold the center tube of the chair, able to stably fix the footrest ring on the center tube of the chair.
