The regulation modules carry out in sequence a current-regulation phase, in which they regulate the current that flows in the corresponding LED strings. The regulation module includes: a compensation regulator coupled to a compensation LED string and to a capacitor and a generator that generates an electrical quantity indicating the luminous flux emitted by the LED strings and by the compensation LED string. The compensation regulator regulates a current that flows in the compensation LED string as a function of the electrical quantity, discharging the capacitor through the compensation LED string.

  • Patent number: 9791133
    Abstract: A lighting control device includes a sensor that detects a state of a user and a gesture made by the user and a controller that controls a lighting characteristic of a lighting device. In the lighting control device and/or the lighting control method, it is determined (by the controller) whether a gesture made by the user and acquired by the sensor matches a first predetermined gesture including a predetermined hand shape and a predetermined movement of both hands of the user made within a detecting region between a boundary 30% larger than a periphery of a projection region illuminated by the lighting device and a boundary 30% smaller than the periphery of the projection region. When it is determined that the gesture matches the first predetermined gesture, a size of the projection region is changed (by the controller).

  • Patent number: 9788382
    Abstract: Systems and methods for maintaining the illumination intensity of one or more LEDs above a minimal intensity level. The systems and methods may include: (1) a current regulator for regulating the current in a circuit; (2) a voltage source for applying current to a circuit; (3) an LED with a minimal intensity level that correlates to a set-point temperature; and (4) a thermal sensor that is in proximity to the LED and adapted to sense a temperature proximal to the LED. The thermal sensor may transmit a signal to the current regulator if the sensed temperature exceeds the set-point temperature. Thereafter, the current regulator may take steps to regulate the current in order to maintain the LED illumination intensity above the minimal intensity level.

  • Patent number: 9723695
    Abstract: A lighting control system is provided with a communication method utilizing downstream current modulation. A primary controller is electrically coupled to a plurality of lighting devices via a mains power transmission network. Each of the respective lighting devices includes an occupancy sensor and is configured to provide full illumination when occupancy is detected in the associated area. The controller identifies occupancy by an increase in current on the mains lines, directs the other devices to fully illuminate, and activates a timer. Prior to lapsing of the timer, any of the devices may indicate continued occupancy by adjusting an operating current to a respective light source according to a predetermined pattern. Upon identifying the pattern, the controller generates control signals directing each of the other devices to remain fully illuminated, and resets the timer. The predetermined pattern may for example include amplitude modulation, threshold numbers of cycles, or both.

    Abstract: Disclosed are methods and apparatus for lighting control based on a combination of inputs. One or more properties of light output of a lighting fixture (120A, 120B, 120C) are controlled based on local input (based on local sensor readings) and group input (provided to the lighting fixture and additional lighting fixtures) and/or one or more sensors (125A, 125B) are auto-calibrated. For example, in some embodiments a lighting controller (130A) of a lighting fixture may receive both the local input and the group input and control a dimming level of a light source (150A) of the lighting fixture based on the local input and the group input. For example, the local input may be based on input from a local sensor that is indicative of a light level near the lighting fixture and the group input may be indicative of a desired group level of dimming.
