A stepless dimming control method of a lighting system is applicable to the situations where a light source for a lighting terminal is a fluorescent lamp and/or an LED lamp. A pulsating voltage regulating device is connected in series with a main power supply circuit of a terminal light source. A dimming control unit is configured for a fluorescent lamp electronic ballast/LED driving unit. The specific method includes: at first, fluctuating a supply voltage value at an input end of the electronic ballast/LED driving unit for a short time by the pulsating voltage regulating device, and then regulating, by the dimming control unit, an output frequency of the electronic ballast and an output current of the LED driving unit according to fluctuation parameters and also in combination with preset system settings, so as to realize dimming. The method can realize remote and stepless dimming, is applicable to the terminal light sources of both fluorescent lamps and LED lamps, has good interference resistance and relatively low system construction/improvement costs, and is extremely suitable for newly-built lighting systems and for use in upgrading existing lighting systems.

Power line communication to control lighting
11683875 · 2023-06-20 · ·

Disclosed herein are systems and methods using power line communication to control light fixtures. The system operates in two phases. In the first phase, a control device generates commands which are encoded on a control signal. The control signal is generated by encoding data using two sinusoidal waves, the second sinusoidal wave being a phase-shifted copy of the first sinusoidal wave. The resulting control signal is sent on a power line. The control signal is received by light fixtures and/or sensors through an ultra-narrow band filter, decoded and converted to executable instructions for the light fixtures and data parameters for sensors. In the second phase, the light fixtures are jointly controlled by the control device and the sensors. The control in phase two is hybrid open loop/closed loop control.

Signal-level based control of power grid load systems

The present invention relates to a load control system in which a power cable of a DC or AC is used for on/off control and dimming of connected load devices without adding significant hardware structure. The control is achieved through a change in the DC or AC bus voltage. A grid controller can perform on/off control and dimming for an entire group of connected load devices by changing the bus voltage. Connected load devices that do understand or want to make use of this feature will be unaffected. In order to reduce the effects of voltage drop, a calibration procedure is provided. The calibration procedure first triggers the connected load devices into a calibration mode and then initiates a number of predefined output level commands that allow the load devices to build an individual correction for the undesired voltage drop.
