An information processing apparatus includes a processor configured to acquire an image obtained by imaging a space by one imaging device fixed in the space, specify, in the image, a two-dimensional coordinate of a bright spot indicating light emission of a light emitting device moving in the space, acquire output information output by the light emitting device, and specify a three-dimensional coordinate in the space of the light emitting device based on the output information and the two-dimensional coordinate.

A load control system may be configured using a graphical user interface (GUI) software. The GUI software may be implemented to collect control devices and add the control devices to the load control system for configuration. Programming data may be automatically determined for the added control devices based on the type of control device, the location of the control device, and/or the load type controlled by the control device. The programming data may include control settings for a scene, a schedule, or an automated control feature. The programming data may be displayed for being viewed and/or adjusted by a user. The programming data may be transmitted to the control devices and/or a system controller for being implemented in performing load control.

Two-wire dimmer operation includes controlling conduction of power to a lighting load. In one aspect, based on a conduction angle adjustment, power supply voltage is monitored and a maximum conduction angle is established based thereon. In another aspect, a dimming level signal is received and a dimming level for a dimmer is set based on the received dimming level. The dimming level signal indicates a desired dimming level for a dimmer, and a maximum value for the dimming level signal is based on a dimmer power supply voltage. In yet another aspect, based on detecting an adjustment to increase a conduction angle of a dimmer, the conduction end angle is increased and the conduction start angle is also increased. This results in a net increase in the conduction angle for controlling operation of the dimmer.

The present invention provides a self-adaptive dimming driving system, comprising: a lamp base, a driving circuit, a lamp identification circuit, and a controller. The lamp base, where an LED lamp is able to be mounted, comprises an LED power port electrically connected to a power input port of the LED lamp. The driving circuit is connected or coupled to the LED power port and configured to modulate power to be output to the LED lamp and output the modulated power to the LED lamp. The lamp identification circuit outputs a test current to the LED power port in order to turn on an identification resistor of the LED lamp, and receives a voltage parameter of the identification resistor as feedback in order to output a detection signal according to the voltage parameter. The controller receives the detection signal, obtains a correlation parameter of the resistance value of the identification resistor according to the detection signal, and switches a power output mode of the driving circuit according to the correlation parameter.

The present disclosure provides an intelligent lighting control system. A controller of the lighting control system causes a phase change cut to be applied to an AC power signal to signal to a light bulb apparatus connected to a luminaire a request to self identify. The encoded phase changed AC power signal is transmitted to the light bulb apparatus for a predetermined time period. A response signal received from the light bulb in response to receipt of the encoded phase changed AC power signal by the light bulb is detected at the lighting control system. A bulb identification is determined based on the response signal from the light bulb apparatus.
