Dyson engineer discussing Dyson Solarcycle LED lighting

"Some lights quickly deteriorate or burn out. I wanted to developed one that wouldn't."

Jake Dyson, Chief Lighting Engineer.

Heat Pipe cooling technology in the Dyson Solarcycle™ task light

Heat Pipe cooling technology. Maintains light quality for 60 years.¹

When LEDs overheat, they can fade and discolour. Dyson engineers addressed this with technology often used in satellites. A vacuum-sealed copper tube draws heat away. Inside, a drop of water evaporates, dissipating heat along the pipe as it condenses, before returning to the LEDs by capillary action. It provides a non-stop, energy-free cooling cycle.

Planet Earth in the night sky

Dyson daylight algorithm. Tracks daylight anywhere, anytime.

Daylight constantly changes – and it varies in different locations. We developed a unique time, date and GPS-driven algorithm to calculate the colour temperature and brightness of daylight, anywhere in the world. Software validation was supported by data selected from over a million atmospheric measurements.

Intelligent optical head. Turns data into dynamic light.

A 32-bit microprocessor continually interprets daylight data, communicating it to the optical driver for dynamic colour tuning. The three warm and three cool LEDs simulate daylight colour temperatures from 2700-6500 kelvin. And with a colour rendering index over 90, the light displays colours very close to daylight.

Colour-mixing chamber. Creates a uniform pool of high-quality light.

A heptagonal reflector split by a layer of PMMA (a lightweight or shatter-resistant alternative to glass) diffusion film evenly mixes light and helps create a single light source for high shadow quality. The lower reflector is engineered to protect eyes from glare and focus light for a pool of uniform illumination (0.7 uniformity).

The Dyson Link app. Personalizes light output.

The Dyson Link app continually communicates data to the light's MCU for dynamic colour tuning – from local daylight data every 60 seconds to manually inputted information, enabling more precise and personalized light settings.
