摘要： A regulator device (10) that includes a plurality of switches (14a-14e) and a control circuit (12, 13) that controls the plurality of switches (14a-14e) is described. The plurality of switches (14a-14e) selectively couple respective strings of the light emitters (18a-18e) in series to the input power to emit light when deactivated. The control circuit may deactivate a number of the switches (14a-14e) to couple the respective light emitters (18a-18e) to the input power in response to a sensed operational parameter of the input power. The control circuit may adjust the number of the switches (14a-14e) deactivated in response to a change in the sensed operational parameter of the input power. A number of the light emitters (15) may be coupled to the input power regardless of the sensed operational parameter of the input power.

摘要： The invention provides a method and system for automatically implementing lighting control scene. The method comprises following steps: connecting the lighting control module to a scene design module, establishing a correspondence between an actual scene controlled by the lighting control module and a simulated scene designed by the scene design module, the photosensitive spots set in the actual scene are mapped to fixed light spots in the simulated scene; connecting photosensitive matrix modules that can be mounted on an indoor ceiling to the scene design module, establishing a correspondence between a sensing range map and a simulated sensing range map, so that the photosensitive spots correspond to at least one light measuring spot on the photosensitive matrix module, the simulated light measuring spots of the simulated photosensitive matrix module correspond to the light measuring spots of the photosensitive matrix modules one to one; The scene design module overlays the simulated scene with the simulated sensing range map, to associate the fixed light spots with the simulated light measuring spots, associate the fixed light spots with the light measuring spots, so that the photosensitive spots correspond to the light measuring spots. Through above steps, the scene designed and rendered by the computer can be directly transplanted to the entity lighting control system, thereby realizing the effect of designing the lighting control.

摘要： The invention relates to a circuit, in particular for operating light-emitting diodes having low flicker and in accordance with standards, having n LED chains having a respective LED number N, wherein n is an integer and greater than 1 and N is an integer and greater than 0, also having a total supply voltage connection, to which a time-dependent supply voltage, in particular rectified a.c. voltage, can be applied, and a LED chain circuitry, wherein the LED chain circuitry has a control device and the LED chain circuitry connects the individual LED chains in stages in the event of rising supply voltage and disconnects them in stages in the event of falling supply voltage. The circuit has a refill circuit, in particular a valley fill circuit, which below a quantitative supply voltage value supplies at least one of the LED chains having a voltage and/or having a current, wherein the circuit has a controllable and/or adjustable current sink, which reduces a supply current of the LED chain by a charging current of the refill circuit.

摘要： A converter controller 32a controls a switching converter 30. A current detection circuit 34 generates a current detection signal V CS that corresponds to a coil current I L of the switching converter 30. An error amplifier 102 amplifies the difference between the current detection signal V CS and an analog signal V ADIM that indicates a current to be supplied to a semiconductor light source 10, so as to generate an error signal V ERR . A hysteresis comparator 36 compares the current detection signal V CS with an upper threshold signal V THH and a lower threshold signal V THL determined according to the error signal V ERR , and generates a control pulse S CNT that corresponds to a comparison result. A driver 38 drives a switching transistor M1 according to the control pulse S CNT .

摘要： An LED controller includes: an absolute value calculator to calculate an initial light intensity value for a desired light output curve; a fade-in calculator to calculate a first light intensity value; and a fade-out calculator to calculate a second light intensity value. The LED controller also includes processing logic configured to: select one of the fade-in calculator and the fade-out calculator as a selected incremental value calculator, based on a directional indicator that indicates whether a fade-in light output effect or a fade-out light output effect is requested, initialize coefficients of the absolute value calculator and the selected incremental value calculator with a set of coefficient values associated with the desired light output curve, and output a set of voltage levels to a set of pulse width modulation (PWM) generators that output a set of PWM signals, which control light output of a string of LEDs.

摘要： The invention achieves suitable operations related to turning on and off a light. For this purpose, the invention comprises: a voltage conversion unit for receiving a direct current voltage, performing voltage conversion, and supplying a drive current to a light source unit having a light-emitting element; a bypass switch forming a bypassing path for the drive current to bypass the light-emitting element; and a control unit controlling the voltage conversion unit and the bypass switch. When lighting the light-emitting element of the light source unit, the control unit first places the bypass switch in the on state and then causes the voltage conversion by the voltage conversion unit to start, and thereafter, turns the bypass switch off and causes the light-emitting element to illuminate.

摘要： Techniques are provided for bi-directional communication between a power supply and one or more light engines (and/or other lighting system components) via the existing power lines so that no additional communication wires are needed. In particular, the power supply can transmit information by modulating its output (voltage or current) and the light engine (or other lighting componentry, such as a sensor) can communicate back by modulating how much power it draws from the power supply. Any suitable type of modulation scheme can be used, and a master-slave arrangement can be used to control the bi-directional communication if so desired, so as to avoid multiple devices communicating over the power line communication channel at the same time. Other embodiments allow a multiple simultaneous communications over the power line communication channel.
