Exclusive free-standing LED luminaire with direct and indirect light output. For standard-compliant illumination of single and double workstations. With integrated light management for the synchronous daytime- and seasonally dependent control of light colour (circadian control) of both light emission surfaces. With Smart Connect equipment for combination with a LiveLink Lightgrid Controller. The luminaire features an integrated daylight- and HF presence sensor with motion direction detection. LiveLink Workplace versions of luminaires in a room can be connected via Bluetooth to form an interactive group of luminaires. The initial detection of movement by any luminaire within the group causes all group devices to switch on at basic lighting level (approx. 300 lx, indirect component). Subsequent detection in the close range of a luminaire triggers this into workplace mode by switching on of the direct component Within the luminaire group, the light colour and HCL curve of the indirect component are harmonised. Parameterisation of the Smart Connect functions is password-protected using a smartphone and an app. Operating the lighting functions is implemented manually via 3 operating elements and via Smartphone app. Communication between the connected luminaires and the smartphone is via Bluetooth Low Energy v 5.0. Single luminaires as well as luminaire groups can be controlled with up to 4 battery-free and wireless radio buttons, which are available as separately ordered accessories. In terms of design and photometric properties, the free-standing luminaire harmonises with suspended and surface-mounted luminaires as well as other free-standing luminaire versions in the project. The luminaire is delivered in 4 packages to protect the individual components. With its wide, slightly asymmetric light distribution, the direct component of the luminaire provides very uniform illumination of the desk surface. The indirect component with Lambertian light distribution provides optimum room illumination. With symmetric limited wide light distribution.
