20150237695 | Powerless Bleeder - A power efficient method and system for ensuring a reliable operation of dimmers in conjunction with solid state lighting devices such as LED or OLED assemblies is presented. A controller for a driver circuit of a solid state light bulb assembly is described. The solid state light bulb assembly comprises a solid state light source. The driver circuit comprises a switched-mode power converter. The controller is configured to receive an input voltage indicative of a mains electricity supply submitted to a dimmer; to determine that the dimmer is in an off-phase, based on the input voltage; and, if it is determined that the dimmer is in an off-phase, to generate a control signal for the switched-mode power converter to operate the switched-mode power converter in a switched mode for discharging one or more capacitances at an input of the switched-mode power converter. | 2015-08-20 |
20150237696 | AC-POWERED LED LIGHT ENGINE - AC LED light engines powered directly from the AC power line contain circuitry of resistors, capacitors, diodes and transistors which enables a single string LEDs connected to series to efficiently produce light with a relatively low level of flicker as perceived by the human eye. The LEDs are driven by a current which is alternately capacitively-limited and resistively-limited. Capacitively-limited pulses of current are interposed between resistively-limited pulses of current so that the resulting output current ripple is at frequencies of 240 Hz or above which the human eye cannot perceive. The combination of resistively-limited current and capacitively-limited current results in a current drain from the power line which is generally sinusoidal and can have a power factor in excess of 0.70. | 2015-08-20 |
20150237697 | AC-DIRECT DRIVE-TYPE LED DRIVING DEVICE - The present invention relates to a device for driving LEDs and, more specifically, to an AC-direct drive-type LED driving device, capable of sequentially driving LEDs connected in series in reverse order by starting with an LED located at the end until a certain size of power is supplied, and sequentially driving the LEDs connected in series in order if the certain size of power is supplied, rather than measuring the size of a rectified power and sequentially driving the LEDs connected in series based on the measured size of the power; thereby equalizing the power consumption of all the LEDs connected in series to thereby equalize the life span of the LEDs regardless of the serial connection order of the LEDs and unifying the brightness of all the LEDs connected in series. | 2015-08-20 |
