Up/Down LED - Dyson - Facility Management Product Release

Up/Down LED: Dyson

website | Company information

The CuBeam Duo suspended light is a combined up and down light that has full, flexible illumination control.

A custom-built driver splits the ratio of light to suit different needs. 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 of working hours, full up light provides a blanket of ambient illumination across the space – ideal for maintenance staff.

Directing light where it’s needed provides optimal visual conditions, preventing wasted light and helping to reduce eye strain.

With adjustable one-touch shutters and a reflective surface, 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.

Cu-Beam suspended lights come equipped with an effective cooling system. Heat is transferred away from the light source and dissipated along the wings. Six vacuum-sealed tubes span the wings of the Cu-Beam suspended lights. 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 vapor. The vapor begins moving along the tubes due to the difference in pressure. As soon as the vapor reaches a cool area of the tube, it 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.

A single light source allows accurate optical control. Precisely calculated optical geometry directs light without compromising output.

The Cu-Beam Duo suspended light is joined in the range by the Cu-Beam down light, a suspended light with a controlled pool of powerful illumination, that's ideal for lighting task surfaces such as meeting tables and office desks. Plus, the Cu-Beam up light that is a suspended light with a wide distribution of powerful illumination, that's ideal for open spaces such as atriums, foyers and general office lighting.
