The controller is built in with a safe voltage threshold, controls the series and parallel voltage divider to be connected in series to the LED unit when an output voltage of the rectification unit exceeds the safe voltage threshold, ensuring that an average voltage across the LED unit and the constant current controller is stable, and controls the series and parallel voltage divider to be parallelly connected across the LED unit and the ground when the output voltage of the rectification unit does not exceed the safe voltage threshold. Accordingly, a safety standard of voltage for LED driving circuit can be secured and users' safety can be ensured.Type: ApplicationFiled: August 22, 2013Publication date: March 6, 2014Applicant: Luxul Technology IncorporationInventors: Cheng-Hung Pan, Perng-Fei Yuh

Publication number: 20140062325Abstract: The present invention relates to a silicon-controlled rectifier (SCR) dimming circuit and method for regulating the luminance of a light-emitting diode (LED) load. In one embodiment, an SCR dimming circuit can include: an SCR rectifying circuit having an SCR element that receives an AC power supply, and generates a lack-phase AC voltage; a rectifier bridge that converts the lack-phase AC voltage to a lack-phase DC voltage, where the lack-phase DC voltage is filtered through a filter capacitor to generate a smooth DC voltage; a conduction phase angle signal generator that receives the lack-phase DC voltage and generates a controlling signal indicating a conduction phase angle range of the SCR element; and a dimming signal generator that compares the controlling signal and a slope reference signal to output a dimming signal to control the luminance of the LED load.Type: ApplicationFiled: October 28, 2013Publication date: March 6, 2014Applicant: Silergy Semiconductor Technology (Hagzhou) LTDInventors: Shenglun Chen, Wei Chen, Xiaoru Xu

Publication number: 20140062328Abstract: The display device includes a light source, and a control section adapted to generate a composite pulse width modulation signal using PWM1 having a first Duty ratio and PWM2 having a frequency higher than the frequency of PWM1, and control a light emitting state of the light source using the composite pulse width modulation signal. The control section corrects a second Duty ratio based on a difference between an expected value of luminance obtained when making the light source emit light using a virtual pulse width modulation signal, which is obtained by combining PWM1 and a pulse width modulation signal having the second Duty ratio, and a setting value of luminance based on the information related to the luminance of the light source, and then uses the second Duty ratio corrected as the Duty ratio of PWM2.Type: ApplicationFiled: August 26, 2013Publication date: March 6, 2014Applicant: SEIKO EPSON CORPORATIONInventor: Takashi TOYOOKA
