Abstract: A balance circuit includes a reference circuit configured to generate current through strings of light emitting diodes (LEDs). The reference circuit includes a first string of LEDs in series coupled to a collector node of a first transistor. A base drive current resistor is connected between the collector node and a base node of the first transistor. A base emitter resistor is connected between the base node and an emitter of the first transistor such that a reference voltage is generated on the base node during operation. Another stage receives the reference voltage to generate a tracking current through a second transistor and a second string of LEDs connected to a base of the second transistor, wherein a current through the first string of LEDs is uniformly tracked by the tracking current through the second string of LEDs.

Abstract: A passive infrared (PIR) motion sensor system includes a non-contact thermopile detector for capturing infrared energy from a focused upon area in a room or zone deemed most likely to be occupied and generating a thermopile temperature signal therefrom, a pyroelectric detector for viewing through multiple passive lens elements (lenslets) that form PIR beams from a large portion of the room or zone and generating a pyroelectric signal therefrom, an ambient temperature sensor for sensing an ambient temperature in the room or zone and generating an ambient temperature signal detection threshold that is utilized in PIR detection therefrom and a microcomputer configured to process the thermopile temperature signal, the pyroelectric signal and the ambient temperature signal and determine whether the room or zone is occupied or unoccupied.

Abstract: This invention is suitable for directly driving from an alternating current (AC) line voltage source an array of LED lamps with a minimal amount of ancillary circuitry. Most of the required circuitry is situated within an integrated circuit, which includes a full wave rectifier, transient protection, a current control transistor, a feedback control loop, and overheating protection. The integrated circuit powers a transistor circuit structured as a constant current source to energize individual groupings of LEDs, as well as larger configurations of LEDs. The invention is useful for various lighting arrangements such as luminaires, bollards, strip lights, task lights, lighting tubes, and other types of applications that use a multitude of LEDs powered directly by AC line voltage without the requirement of a direct current power supply. This invention may further be used with an external phase switching dimmer apparatus.

Abstract: A micro-motion occupancy sensor system monitors for a presence of a person in a room, in different monitoring modes, to regulate power delivery to the room. The micro-motion occupancy sensor has a multimode lens for receiving passive infrared (IR) energy and focusing the IR energy as a series of IR beams, a pyroelectric detector to receive the focused IR beams and generate an electrical signal, a processing circuit to amplify, filter and processes the electrical signal to generate an interrupt signal and an analog output signal and a controller that receives and processes the interrupt signal and the analog output signal to determine whether a person has entered a room or is maintaining their presence within the room. The controller controls the processing in a vacant mode where a person's presence is not detected and in an occupied mode when a person's presence has been detected.
