Patent number: 10172205Abstract: A dimming module includes a triggering circuit, a control signal generating circuit, a voltage converting circuit, and a linear driving circuit. The triggering circuit is configured to control a trigger delay angle of an AC input voltage according to a dimming command, in order to output a first voltage signal correspondingly. The control signal generating circuit is configured to output a control voltage according to the first voltage signal. The voltage converting circuit is configured to output a DC operating voltage having an operating level according to the first voltage signal, and output the DC operating voltage to a lighting module, in which the lighting module includes a light-emitting diode. The linear driving circuit is configured to drive the lighting module according to the control voltage.Type: GrantFiled: May 9, 2017Date of Patent: January 1, 2019Assignee: LEXTAR ELECTRONICS CORPORATIONInventors: Jhao-Cyuan Huang, Chien-Nan Yeh, Chun-Jong Chang, Ching-Piao Chen, Po-Shen Chen

Publication number: 20160305184Abstract: A curtain blade contains: a body and a two reinforcement ribs. The body is made of any one of bamboo veneer, wood veneer, and linen fabric and includes two long sides, wherein each reinforcement rib is covered on each of the two long sides of the body so as to reinforce said each long side. Said each reinforcement rib has an accommodation groove defined therein and corresponding to said each long side of the body, hence said each reinforcement rib is fitted on said each long side, and said each long side of the body inserts into the accommodation groove. The curtain blade is therefore fixed firmly and obtains aesthetic appearance. Preferably, said each reinforcement rib protects said each long side of the body effectively so as to prolong service life of the curtain blade.Type: ApplicationFiled: March 24, 2016Publication date: October 20, 2016Inventor: Ching-Piao CHEN

Patent number: 7059381Abstract: A flexible curved window is made by arranging a plurality of fine size elongated rods in a parallel manner. A plurality of strings interlaced between alternate ones of the rods to form a matt-like base structure and a flexible liquid absorbent sheet material wetted with adhesive is applied over the surface of the matt-like base structure and then trimmed to fit the size of the latter. When the adhesive is dried and set the contraction of the sheet material causes the blind to curve towards the surface having the sheet material.Type: GrantFiled: November 15, 2004Date of Patent: June 13, 2006Inventor: Ching-Piao Chen
