Dyson introduces the Cu-Beam Duo suspended light – up and down light with full control

Fluorescent lights can create problems, including reduced light output over time, wasted light in all directions, costly replacement, noise pollution and hazardous material. An increasing number of businesses are opting for LEDs. But without effective cooling, their efficacy may drop over time, which can result in inefficient lighting. Jake Dyson’s Cu-Beam suspended light technology works differently.

People have different needs, across different spaces, at different times throughout the day. And, for optimal visual conditions, each one requires different light levels. That’s why, with the new Cu-Beam Duo suspended light, Dyson has designed a powerful, combined up and down light that has full, flexible illumination control: a custom-built driver splits the ratio of light to suit different needs.

With adjustable one-touch shutters and a reflective surface, Dyson’s Ricochet technology converts unwanted down light into up light, preventing light being wasted. For up light, closing the adjustable shutters allows recovery of unwanted down light. It reflects it upwards, to maximize lumen output and provide very high efficacy. For down light, opening the shutters allows more lumens to go downwards, to maximize downward light distribution onto the task plane.

During presentations, more light can be directed upward and less light downward, so the presenter’s screen can become the focal point. During meetings, more light directed downward illuminates the table, to aid note-taking and discussions across the table. Outside working hours, full up light provides a blanket of ambient illumination across the space – ideal for maintenance staff.

Cu-Beam suspended lights also come equipped with an effective cooling system. Heat is transferred away from the light source and dissipated along the wings.

This is effected via the six vacuum-sealed tubes that span the wings of the Cu-Beam. Each tube contains a drop of water; when the light is switched on, the heat generated by the LEDs turns the water inside the tubes into vapour. The vapour begins moving along the tubes because of the difference in pressure; when it reaches a cool area of the tube, the vapour condenses back into water. Heat energy is dissipated evenly through a series of aluminium fins, which form the light’s wings. A copper wick draws the water back towards the LEDs via capillary action, and the cycle begins again.

This cooling system enables Cu-Beam suspended lights to use high-power LEDs, instead of combining the light output of multiple less powerful LEDs.

The Cu-Beam line is designed by Jake Dyson, the eldest son of James Dyson, who studied product design at Central Saint Martins College of Arts and Design in London and subsequently worked as a retail designer. In 2004 he set up a small workshop in South West London to produce his first commercial product – the Motorlight wall light. The developing technology of LEDs captured his interest and became an area of focus for him and his team.

Jake’s business became part of Dyson in 2015, and he is now a R&D Director of Dyson and sits on the board. He works with Dyson’s wider team of engineers and scientists on future technology portfolios in lighting and beyond.

Dyson is a global technology company with a team of 3,500 engineers and scientists spending around £7 million a week on research and development.
