Abstract

An I2C and Manchester multiple serial interface LED driver programmer has a programmer that changes the operation parameters in the EEPROM of the LED driver via a computer graphic user interface. The LED driver operation is thus programmed according to the parameters stored in the EEPROM. The multiple interfaces are selectable as USB-to-I2C, RS232-to-I2C, USB-to-TxD/RxD, RS232-to-TxD/RxD and 3rd via a pass through USB-to-USB port for expanded LED programming interface such as Near Field Communication. The I2C and Manchester multiple serial interface LED driver has multiple output interface with USB-to-I2C, RS232-to-I2C, USB-to-TxD/RxD, RS232-to-TxD/RxD and third pass through USB-to-USB port for Near Field Communication interface.

Abstract

A phase control dimming LED driver is able to achieve complete stabilization of both TRIAC and trailing edge dimmers by using a large inductor to limit the inrush normally associated with the switching on of the TRIAC during each half cycle. Such a large inductor is not normally used because when a trailing edge dimmer is applied, a damaging voltage surge known as “ring up” can be generated when the trailing edge dimmer switch turns off. In this invention the inductor is placed after the input rectifier bridge and equipped with a diode and resistor which allow the energy in the inductor at the moment when a trailing edge dimmer switches off to be harmlessly dissipated.

Abstract

A circuit is described which allows an LED driver to be controlled by a control signal in such a manner that at a predetermined dimming level the output current goes to zero instead of continuing to indefinitely low dim levels, thus avoiding the possibility of flickering or shimmer at extremely low dim levels. An electronic circuit for driving an LED load with a conventional LED drive circuit has inputs connected to a power source and output terminals providing regulated output power including a load disconnect switch in series with the LED load which has a control node responsive to a control circuit; and a control input which commands varying levels of input power. The control circuit is configured to be responsive to the control input so that when the control input corresponds to a certain continuous level of dimming, the load disconnect switch is opened.
