Color tunable lighting systems and methods are disclosed. The color tunable lighting systems and methods include user interfaces that allow for the control of color temperature and luminous intensity by a user. The systems and methods provide for flexibility and scalability, where a control module for controlling one or more solid state light source arrays can be programmed during installation for use with specific solid state light source arrays.

Tuneable lighting systems and methods

Serrated light engine and circuit board

A power supply system providing communication from a master module to at least one slave module via transients, to alter operation of a load, is provided. The master module output a supply voltage that is either a normal supply voltage or a reduced supply voltage. The outputted supply voltage depends on input corresponding to a communication to be sent to the slave module to alter operation of the load of the slave module. The slave module receives the supply voltage and interprets the received supply voltage, which may vary between the normal and reduced supply voltages, to determine what the communication from the master module is. The slave module then uses information from the communication to appropriately alter operation of its load.

Transient  power communication

A substrate for a solid state lighting module has a plurality of serrated finger sections extending from an interconnecting base. The substrate may be formed from a single rectangular sheet by cutting away material between adjacent finger sections of a symmetrical second substrate to form the finger sections of the substrate. Parallel linear rows of solid state light sources may be disposed along the length of each finger section. For example, the solid state light sources may be disposed proximate to points of sawteeth at the edges of the finger sections.

Shaped substrate with arrangement of solid state light sources

Circuits to provide phase-cut analog dimming of solid state light sources are presented. Each circuit comprises an anchoring circuit to communicate with a dimming controller circuit, the anchoring circuit having a proportional direct current (DC) voltage input, a biasing voltage input, a connection to a ground reference, and an output in communication with a dimming controller circuit. The anchoring circuit provides a reference voltage to permit phase cut dimming to be operable at a plurality of line voltages.

Power supply enclosure with light engine holder

Techniques and corresponding circuitry and drivers are disclosed for improving power factor (PF) and total harmonic distortion (THD) of a flyback power factor correction (PFC) topology operating in transition-mode. In one or more embodiments, the PF and THD are improved by correcting the on-time of the switching element of the flyback PFC topology to actively shape the wave of the PFC input current. In some embodiments, the on-time is corrected using a phase-lock-loop module that synchronizes with the rectified input line voltage signal and a output regulator module that corrects the switch on-time. The control may be implemented using a digital or an analog controller.

Transient power communication

Systems and methods for pulse-based binary communication are provided. An example system may include a transmitting device and a receiving device. The transmitting device may be configured to generate a supply voltage for use in operating the receiving device and to cause at least one pulse to occur in the supply voltage, the at least one pulse being based on a binary value. The at least one pulse may comprise, for example, a temporary change in the supply voltage. The receiving device may be configured to receive the supply voltage from the transmitting device, to detect the at least one pulse in the supply voltage and to determine the binary value based on the at least one pulse. The receiving device may then perform an action based on the binary value.

Pulse-based binary communication

Modular multichannel light sources connector systems and methods are provided. A lighting assembly includes substrates, each with a respective plurality of ports and conductive path configurations. Each path configuration includes a plurality of conductive paths between the respective plurality of ports. At least two conductive path configurations are the same. A connector couples one of a plurality of first ports on a first substrate to one of a plurality of second ports on a second substrate. A multichannel power supply's outputs are each coupled to an associated conductive path on the first substrate. A first light source is coupled to two conductive paths on the first substrate, and to a first output. A second light source is coupled to two conductive paths on the second substrate, corresponding to the conductive paths on the first substrate, and to a second output, different from the first output.
