Jake Dyson Light Unveils New Ariel™ Pendant Light
The Past, Present, and Future of Light Technology, As Envisioned by Dyson
Inside the Dyson Omotesando store, the new Ariel™ pendant light from Jake Dyson Light, led by James Dyson’s eldest son, Jake Dyson, is used in the LED spotlights illuminating the products. With a full-scale launch in Japan on the horizon, Jake Dyson visited to discuss light technology.

Heat: The Nemesis of LED Lifespan
Jake Dyson Light began in 2004 as a small workshop in southwest London, founded by Jake Dyson and two engineers. While researching LED technology, they became convinced that "heat degrades LEDs. If we can maintain a low temperature, LEDs should last a lifetime." They started R&D to find ways to dissipate heat from LEDs.
"LEDs generate light from semiconductor chips, but they also produce a significant amount of heat. This heat causes the chips to degrade over time, leading to a loss of brightness and color," Jake explains. He then turned his attention to technology used in satellite cooling systems, developing "heat pipe technology" for LEDs.
"I was determined not to create lighting with fans. That's why I focused on heat pipe technology, known for its excellent cooling capabilities. It's a system that dissipates the heat generated by the LED chips, maintaining uniform brightness, color, and energy efficiency. This feature is designed to last over 37 years with 12 hours of use per day," he says.
A Masterpiece Born from Solving the Problem of Overheating
Heat pipe technology was first implemented in the previously released CSYS™ task light. It features a function that transports heat generated by the LED elements to an aluminum heat sink.
While typical LED lighting can emit heat between 120-140 degrees Celsius, the CSYS™ uses a long, 6mm diameter heat pipe to cool the LEDs, stabilizing them at a low temperature of 55 degrees Celsius. This achieves an exceptionally long lifespan of approximately 780,000 hours.
New Product with 6 Heat Pipes Offers 100,000 Hours of Use
Regarding the newly unveiled Ariel™, Jake explains, "The name Ariel comes from a British satellite in the 1960s. Ariel uses six heat pipes to maintain the LED temperature at 47 degrees Celsius, offering approximately 100,000 hours of use as a pendant downlight. Its latest LED technology ensures uniform light distribution. It's ideal for workspaces like office desks, conference tables, and kitchen islands."
Furthermore, Jake notes that the heat pipe technology allows for "an approximately 8% reduction in electricity costs." The Ariel™ series also includes an uplight type that indirectly illuminates the ceiling.
Performance Dictates Design
On the topic of Jake Dyson Light joining the Dyson brand, founded by his father James Dyson, Jake stated, "We share a commitment to relentless research and development, and the common goal of creating designs that remain beautiful even 40 years from now. We will continue to pursue next-generation technology with the understanding that performance dictates design."
