Jake Dyson Light – CSYS™ Desk Light

A vacuum-sealed copper tube spans the arm of each CSYS™ task light. This tube contains a drop of water, which rests above the LEDs when cool. When the light is switched on, the heat generated by the LEDs turns the water inside the tube into vapour. This vapour begins moving along the tube due to the difference in pressure. As soon as the vapour reaches a cool area of the tube, it condenses back into water. The remaining heat energy is dissipated through the aluminium heat sink that forms the light's horizontal arm. A copper wick draws the water back towards the LEDs via capillary action, and the cooling cycle begins again.

Neglecting to protect LEDs from heat can damage their phosphorous coating, degrading brightness and colour. Jake Dyson Light's CSYS™ task lights use Heat pipe technology to direct heat away from their LEDs, sustaining brightness for up to 144,000 hours*. Heat pipe technology also allows for 8 high-power LEDs to be positioned just 8mm apart, providing a powerful light output of 648 lux over 1m2. *Calculated lifetime based on LED L70

While conventional lights rely on tension to stay in position, CSYS™ task lights use gravity. The arm moves vertically using a counterweight pulley system inspired by the construction crane. It also extends 10.8 in horizontally along anti-friction bearings. The zinc alloy base rotates smoothly through 360°, and is weighted to increase stability. You can position the light exactly where you need with just the touch of a fingertip.

Touch-sensitive, continuous dimming makes the light suitable for many tasks. Built-in memory recalls your most recent light level setting. Each LED is fixed in position and housed in a conical reflector to control glare.
