ECI Lighting celebrated its appointment as an official distributor of Dyson Lighting products for Ireland at an event held recently in the ‘Tramline’ in D’Olier Street in Dublin. Dyson Lighting experts were on hand to answer questions and demonstrate advantages of this new system to the architects, engineers and designers that attended the presentation.
The Cu-Beam suspended light fitting and the CSYS task light both use innovative heat pipe technology to cool the LEDs for a powerful, longer light. Paul Whittaker, Dyson Engineer-Advanced, brought us through the products.
Introducing the Cu-Beam Duo suspended light.
Combined up and down light with full flexible control. Alters to suit changing needs throughout the day.
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 LED lights, but without effective cooling, their efficacy may drop over time, which can result in inefficient lighting. Cu-Beam™ suspended light technology works differently.
“The team and I have spent 10 years immersed in the science of powerful, long-lasting illumination. Now, we’ve developed a lighting technology that can adapt to different tasks throughout the day.”
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.
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.
Ricochet™ technology maximizes the output of every lumen.
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.
Heat pipe technology
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 Range
In addition to the Cu-Beam Duo suspended light, there are two additional products in the range:
The Cu-Beam up-light is a suspended up-light with an ultra-wide distribution of powerful illumination. Using a custom-engineered bubble optic lens, it casts a wide pool of light across the ceiling. This eliminates hot spots and allows a short drop height, creating soft, ambient light throughout the room. It is ideal for lighting open spaces, such as atriums, foyers and offices.
The Cu-BeamTM down-light is a suspended down-light with a controlled pool of powerful illumination. Using a custom-engineered lens and employing precisely calculated optical geometry, it takes a single light source and creates a targeted pyramid of light over a task area. It is ideal for lighting task surfaces, such as meeting tables and office desks.
