Arrangements for controlling a climate control system are provided. A hazard detector of a group of smart devices may detect a carbon monoxide (CO) alarm condition at the hazard detector. The hazard detector may transmit, via a relatively low-power mesh communication network, an indication of the CO alarm condition to one or more other smart devices. A spokesman node of the relatively low-power wireless communication network may translate the indication of the CO alarm condition from a first wireless communication protocol to a second wireless communication protocol. The spokesman node may transmit the indication of the CO alarm condition to a system controller via a relatively high-power wireless communication network and the second wireless communication protocol. A system controller of the climate control system may transmit a signal to turn off at least part of the climate control system.

A solid-state circadian rhythm lamp and related control techniques are disclosed. The lamp may have a night/pre-sleep emissions mode in which it emits light having a correlated color temperature (CCT) of about 1,800-2,300 K, the spectral power ratio of blue light (400-495 nm) being such that it constitutes about 10% or less of the total light emitted. The lamp may have a day/wakeup emissions mode in which it emits light having a CCT of about 5,000-8,000 K, the spectral power ratio of blue light being such that it constitutes about 30% or more of the total light emitted. The lamp may have a general lighting mode in which it produces a combined light output having a CCT of about 2,500-5,000 K. The lamp driver may support emissions mode changing based on hysteresis relating to a lighting switch associated with a power socket hosting the lamp.

The present disclosure relates to a method and apparatus for controlling an illumination device, such as a light bulb, LED light, or the like. In one embodiment, a lighting control adapter is described, comprising a male base for physically attaching the lighting control adapter to a light fixture and for receiving power from the light fixture via a light switch connected to the light fixture, a female socket for receiving a base of an illumination device, a switching circuit for providing switchable power to the illumination device, and a processing circuit coupled to the switching circuit, for detecting one or more power toggles of the power received by the male base, and for controlling illumination of the illumination device based on the detection of one or more detected toggles.

A lighting system configured for daylight emulation. The system includes a plurality of light sources for generating a daylight-emulating output light spectrum. The system also includes a controller for dynamically controlling at least one of the intensity, directionality and color temperature to emulate sun position for at least one of a geography and time of day. The system further includes a networking facility that facilitates data communication with at least one external resource.

A load control system may comprise load control devices for controlling respective electrical loads, and a system controller operable to transmit digital messages including different commands to the load control devices in response to a selection of a preset. The different commands may include a preset command configured to identify preset data in a device database stored at the load control device and/or a multi-output command configured to define the preset data for being stored in the device database. The system controller may decide which of the commands to transmit to the load control devices in response to the selection of the preset.

Disclosed herein is a lighting system configured to obtain an indicator data of a RF signal generated at a number of times in an area. When each such time is a current time, the indicator data generated at the current time is compared with the indicator data generated at a preceding time to determine a rate of change, and the indicator data generated at the current time is compared with a baseline indicator data at an earlier time to generate a difference value. The lighting system is configured to determine an indicator data metric based on the rate of change and the difference value and compare the indicator data metric with one of a rising transition threshold or a falling transition threshold to detect one of an occupancy condition or a non-occupancy condition in the area.

Apparatus, systems, and methods for controlling light output in a lighting system based on defined light profiles are provided. In one example implementation, a light fixture can include a first light emitting diode (LED) array having one or more LED light sources and a second LED array having one or more LED light sources. The light fixture can include a power circuit configured to provide power to the first LED array and the second LED array according to a power distribution among the first LED array and the second LED array. The light fixture can include one or more control devices configured to control the power circuit to adjust the power distribution among the first LED array and the second LED array based at least in part on a signal indicative of a real time clock and a defined light profile associated with a user identified to be present in a space illuminated by the light fixture.

Lighting units, systems, and methods are described herein for determining whether occupancy detections are legitimate or not. Methods and systems are further described herein for powering down a network of power over ethernet (PoE) components.

The examples relate to various representations of data utilized for control of a software configurable lighting device. The software configurable lighting device includes an image display device and a general illumination device. Each data representation includes a pre-defined data structure such that lighting control information and image data may be interlaced within the respective representation.

An operating method for a server includes: displaying, on a screen of a user terminal, a first user interface including a first image obtained by correcting a captured image; displaying, on the screen of the user terminal, a second user interface including a first control point, a second control point, and a segment connecting the first control point to the second control point; obtaining a first user input from the first control point or the second control point; and in response to the first user input, displaying, through the first user interface, a second image obtained by correcting the captured image based on rotational information determined by the first control point, the second control point and the segment, and a center position of the first image.
