Home > Companies > Dyson > Cu Beam

Cu-Beam™ suspended lights provide powerful light, precisely where it is needed. Heat pipe technology creates a highly effective cooling system, meaning each light can use a single high-power, high-efficiency chip on board LED. This single light source, combined with a custom-designed PMMA lens, delivers optically efficient, precisely controlled illumination.

The cooling system also prolongs the life of the light, ensuring long-lasting performance and colour stability. A customized long-life Digital Addressable Lighting Interface (DALI) driver, with additional heatsinks and high-grade capacitors, is engineered to last as long as the luminaire.

Cu Beam down:

Sleek suspended luminaire with single high efficiency chip on board LED CRI 80 min 2 step binning – cooled via sintered copper heat pipes. Unique rectangular distribution optic with adjustable trim blades for optimum framing and glare control. Power over suspension cable DALI driver.

Cu Beam up:

Sleek suspended luminaire with single high efficiency chip on board LED CRI 80 min 2 step binning – cooled via sintered copper heat pipes. Unique toroidal optic with ultra-wide 160° distribution for shallow mounting height. Wide and even distribution of light across the ceiling for even ambient lighting. Power over suspension cable DALI driver.
