Abstract: A light engine driven directly from the AC power line has multiple series connected arrays of LEDs each with an associated current limiting transistor. The current from each current limiting transistor goes through a corresponding current sensing resistor and all these resistors are connected in series. The voltage across each current limiting transistor is applied across the next LED array so that as the voltage increases during the power line cycle, the next array becomes activated by the increasing voltage across the previous current limiting transistor. When this happens the previous current limiting transistor is turned off. This continues until all the arrays are activated at the peak of the line, at which point the array current is controlled by the last current limiting transistor.

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: An LED driver includes a first stage. The first stage converts AC power from an AC power source into a DC power source. The driver also includes a second stage that receives the DC power from the first stage. The driver has a buck converter with a constant current output. The buck converter is managed by a buck converter control chip. The buck converter control chip is controlled by a microprocessor with an associated EEPROM. The EEPROM stores settings for the LED driver can be changed either with a wired GUI port or wirelessly through a Zigbee interface. The microprocessor can select a value of a DC output current according to a value of the analog dimming input signal which has been translated using a predetermined programmable relationship between the input signal and the output current.

Abstract: An LED driver has a primary side regulation with at least one input connected to the AC power line, and at least two outputs. At least one output is for driving LEDs and at least one output is for providing auxiliary power for associated circuits. The driver is constructed using the flyback principle, having at least one flyback transformer which has at least one primary winding connected to a flyback switching transistor. At least one principal output winding is connected to the LED load, and at least one feedback winding is connected to a control chip. At least one auxiliary winding drives the auxiliary power output. The auxiliary winding has a coupling coefficient to said feedback winding which is greater than the coupling coefficient between the principal output winding and the feedback winding.

Abstract: A dual sensor lighting controller has an AC input rectifier that includes an EMI filter, and an isolated AC-to-DC converter for 12 VDC and 5 VDC supplies, and a mechanical relay to control output AC Line voltage for the lighting device. The lighting controller also includes a motion PIR sensor, an internal photo sensor, an external photo sensor and an infrared receiver configured to receive signals from a remote control. The remote control is a handheld battery operated infrared remote control. Two wires provide 0-10 VDC dimming and a microcontroller preferably includes proprietary firmware controls. The microcontroller is connected to and reads PIR, internal or external photo sensors signals. The microcontroller has a clock that counts internal timing to control an output of the lighting device by a mechanical relay together with 0-10 VDC dimming control to save Electrical energy by activating or deactivating the output AC Line voltage.

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 wireless operated LED lighting controller has both analog and phase control outputs which operate a dimming luminaire, and sensors for lighting and motion which operate autonomously as needed. In addition it is locally operated by a handheld infra-red controller. At least one sensor can be chosen from the group of: a light detector, a motion detector, an acoustic detector, a temperature sensor, and a microwave detector. The sensor is electrically connected to the phase control output. A light output of the controller is affected by signals detected by the at least one sensor. The lighting controller has the phase control output enabled for either a leading edge dimming or a trailing edge dimming, and has a mode for completely turning off the dimming luminaire.
