摘要： An automated dimming load controller automatically measures the relationship between the current draw and the dimmer setting for each light or group of lights connected to the load controller. Once measured, the relationship between the current draw and the dimmer setting can be used to enable the dimmer controller to adjust the lights between their minimum and maximum effective illumination. This automatic setting of the dimmer controller may be performed regularly to accommodate changes in performance or replacement of any of the connected lights, drivers or ballasts.

摘要： A display system and a control method are provided. The display system includes a display device, an illumination device and a control circuit. The display device includes a display panel. The display panel is configured to display an image frame. The illumination device is movably disposed on the display device. The illumination device selectively projects light in a first direction or in a second direction different from the first direction. When the illumination device projects the light in the first direction, the control circuit generates a first control signal so as to control the illumination device to perform a first illumination mode. When the illumination device projects the light in the second direction, the control circuit generates a second control signal so as to control the illumination device to perform a second illumination mode different from the first illumination mode.

摘要： A luminaire which provides illumination (in some cases, in a coordinated manner with other nodes of a lighting network) in an industrial environment is further configured to serve as a node of a wireless process control or industrial network, which may be a mesh and/or time-synchronized wireless network. Upon detecting a loss of mains power and/or other triggering condition, the luminaire node allocates an amount of available battery power to maintain the routing of process control messages, and allocates at least some of a remaining amount of available battery power (if any) for performing lighting activities such as driving illumination and/or lighting-related communications. The allocations for (e.g., the relative priorities of) support for process control and support for lighting activities may be based on an allocation configuration and/or based on instructions received from other components of the process control network and/or the lighting network, which may include user interface devices.
