Dyson Lightcycle™ task light – Technology


"For over a decade, we’ve been developing lighting technology that doesn't quickly deteriorate or burn out."

Heat Pipe cooling technology in the Dyson Lightcycle™ task light

When LEDs overheat, they can fade and discolor. 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

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

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

Hand performing a shadow underneath CD04

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 demonstration

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