Abstract:
In one embodiment, a driving circuit includes an AC/DC converter which converts an AC voltage to a DC voltage and a DC/DC linear regulator which regulates a current through, e.g., an LED light source, according to a first current reference if a monitoring signal indicating the DC voltage is within a predetermined range, and regulates the current according to a second current reference less than the first current reference if the monitoring signal is beyond the predetermined range. In another embodiment, a controller controlling power to an LED light source turns on a first plurality of LEDs and turns off a second plurality of LEDs if a monitoring signal indicative of a DC voltage received by the LED light source is within a predetermined range, and turns on both first and second plurality of LEDs if the monitoring signal is beyond the predetermined range.

Abstract:
The present invention discloses a video communication method and system, wherein, during an audio conversation between a calling party and a called party, an IMRS (Integrated Media Resource Server) plays a video to the calling party or the called party; or when a calling party initiates a video phone call request to a called party which does not support video phone call, an audio channel is established between the calling party and the called party and a video channel is established between the calling party and an IMRS, and when an audio conversation is established between the calling party and the called party, the IMRS plays video to the calling party; or when an audio conversation and a video conversation are established between a calling party and a called party, one party replaces its video with that played to the other party by the IMRS, therefore capabilities of developing new communication services are improved.
Abstract:
A controller for controlling dimming of a light-emitting diode (LED) light source provides a pulse signal by comparing a sensing signal indicative of a current flowing through the LED light source to a reference signal. The controller controls the current through the LED light source according to the pulse signal during a first state of a pulse-width modulation signal and cutting off the current through the LED light source during a second state of the pulse-width modulation signal. The controller receives a dimming request signal indicative of an operation of a power switch coupled between an AC power source and a bridge rectifier and adjusts both a level of the reference signal and a duty cycle of the pulse-width modulation signal based on the dimming request signal.
Abstract:
A dimming controller for controlling power of a light source has a monitoring terminal, a dimming terminal, and a control terminal. The monitoring terminal is operable for receiving a current monitoring signal indicating a current flowing through the light source. The dimming terminal is operable for receiving a ramp signal. The voltage of the ramp signal increases if a power switch coupled between a power source and the light source is turned on. The control terminal is operable for providing a control signal to control a control switch coupled in series with the light source based on the current monitoring signal and the ramp signal. An average current of the light source increases as the ramp signal increases until the average current reaches a predetermined level.
