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 wireless lighting control module for LED lighting includes a Zigbee wireless receiver receiving an input wireless control signal, an analog control output which conforms to the 0-10V format, and a microcontroller which is connected to the wireless receiver and receives the input wireless control signal from the wireless receiver. The microcontroller regulates the analog control output. The analog control output has a predetermined cutoff level. A lighting power output is controlled by the microcontroller and cut off by opening a relay when the analog control output is below the predetermined cutoff level. The predetermined cutoff level of the analog control output is 0.5V.

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 Zigbee Lighting Control Module is described which can be connected to the input of an analog dimming LED driver so that a Zigbee controlled analog signal can be applied to the dimming input of the LED driver. Particular features of the module are the capability to apply a chosen nonlinear transform between the digital Zigbee input signal and the 0-10V analog output signal, and the use of a relay to cut off power to the driver being controlled when the analog output signal goes below a chosen level. The module can provide 100 mA output currents allowing large numbers of LED drivers to be controlled at once.
