    Abstract: A method is disclosed for maintaining a desired optical output in a solid state illumination device, where the device is configured to accommodate multiple light emitting diodes (LEDs) and to combine light from the LEDs to produce a single optical output. The method includes testing the LEDs before adding them into the device. The testing produces characterizing information that describes how one or more optical properties (e.g., optical power and/or peak wavelength) of the tested LED change with temperature. This characterizing information is stored in a computer-based memory of the device, and the tested LED is added (connected) into the device. Then, during operation, temperature sensors measure a temperature associated with each respective LED in the device, and electrical current to one or more of the LEDs can be adjusted based on the measured temperatures associated with each LED and its stored characterizing information.

  • Patent number: 10620601
    Abstract: A control device searches for a device to which a global identification (ID) including a manufacturer ID and a device ID is assigned in advance, by searching for the global ID. The manufacturer ID is set for each manufacturer using m bits, and the device ID is uniquely set by each manufacturer using n bits. M and n each are a natural number. The control device includes: a storage storing the manufacturer ID; an inquirer designating a possible range of the global ID at a time when m bits indicated by the manufacturer ID stored in the storage are fixed, and making, to devices connected to the control device, an inquiry about whether a global ID assigned to the device is in the possible range; and a receiver receiving, from the devices, a response to the inquiry, the response indicating that the global ID is in the possible range.

  • Patent number: 10548198
    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: 10530268
    Abstract: A load control device for controlling the power delivered from an AC power source to an electrical load includes a thyristor, a gate coupling circuit for conducting a gate current through a gate of the thyristor, and a control circuit for controlling the gate coupling circuit to conduct the gate current through a first current path to render the thyristor conductive at a firing time during a half cycle. The gate coupling circuit is able to conduct the gate current through the first current path again after the firing time, but the gate current is not able to be conducted through the gate from a transition time before the end of the half-cycle until approximately the end of the half-cycle. The load current is able to be conducted through a second current path to the electrical load after the transition time until approximately the end of the half-cycle.

  • Patent number: 10485068
    Abstract: A presence or an absence of an occupant is detected, and an occupancy sensor signal is generated representative of an active state in which the presence of the occupant is detected, and an inactive state in which the absence of the occupant is detected. An ambient light sensor detects the ambient light level and generates an ambient light sensor signal representative of the ambient light level. Dimmable illumination is generated at a first dimming level, based on the ambient light level, corresponding to the active state and a second dimming level corresponding to the inactive state. A transition delay time between an onset of the inactive state and a transition between the first dimming level and the second dimming level may be controlled. The first dimming level, the second dimming level, and/or the transition delay time may be variably set or controlled locally or via a remote device.
