LuxLive 2019 Innovation: LumiCloud Digital

The LumiCloud Digital LED platform on show at the lightspace section of the LuxLive 2019 exhibition. It featured a circular cut-out to show lighting designers the array behind the diffusing stretch-PVC material

CANADIAN dynamic LED specialist TLS International used the 2019 LuxLive exhibition to showcase its unique LED array technology, LumiCloud Digital.

The addressable LED array sits beneath a diffusing stretch-PVC material and is customisable to practically any size, from a daylight-mimicking artificial skylight for a hotel to a dramatic colour-changing light-art feature for a retail store.

LumiCloud Digital is a modular platform for dynamic LED lighting that’s designed to be fast to install and easy to control.

The addressable LED array sits beneath a diffusing stretch-PVC material and is customisable to practically any size, from a daylight-mimicking artificial skylight for a hotel to a dramatic colour-changing light-art feature for a retail store.

CE and UL certified, the Lumicloud Digital system doesn’t require a mounting substrate and offers a unique protocol that allows individual RGB pixel control for a large-scale LED matrix.

It’s a self-tensioning design, which makes it dramatically easier and faster for installers as there’s no need to individually attach the columns of LEDs.

It comprises a series of narrow circuit boards, each containing a row of pixels, which are attached to a combined 24V DC power, control data and structural-suspension cable to form a ladder arrangement.

The installers attach one end to the supporting wall, tension it at the ends, and simply connect power and data at one end.

The secure but flexible tension cables allow the system to fit many organic and unusual shapes.

It features a clever magnetic auto-alignment system which makes large installations easier to install by automatically aligning rows with the adjoining ones thanks to integrated magnetic contacts.

LumiCloud Digital has already attracted acclaim in a dynamic light art feature at Broadgate in the City of London

The units also feature an optically-efficient reflective backing which seals the unit, prevents the ingress of dust and, crucially, increases the light output by 15 per cent.

LumiCloud Digital has already attracted acclaim in a dynamic light art feature at Broadgate in the City of London, where it was specified by the leading lighting design practice Speirs + Major.

The installation comprises a circular five-metre diameter iteration of LumiCloud Digital, showcasing specially-commissioned dynamic content from artists Ronan Devlin and Michael Flückiger.

The stretched-fabric diffusing screen is powered below by a LumiCloud Digital low-resolution matrix with 4,700 RGB pixels.

‘It’s a really cost-effective solution to low-res matrices like this,’ says Ruxton.

Another high-profile application of LumiCloud Digital will be at Louis Vuitton refurbished flagship London store on New Bond Street.

A key element will be dramatic lighting to a design by George Sexton Associates, with the wow factor delivered by a 5m x 3m light feature powered by LumiCloud Digital

There are four huge light panels in the store’s ceiling, each capable of dynamic colour-changing and scene setting, punctuated by spotlights in recessed slots.

The larger panels contain some 2,860 RGB LED pixels, while the smaller ones have 1,300 each, all driven by a proprietary DMX pixel-control system.
