Jake Dyson is Fixing The Way We Light Up Our Homes and Offices

Desk lamps with shades over globes, downlights in household ceilings, fluorescent light fixtures in offices.

Dyson s chief engineering complaint is with the way that comparatively new LED bulbs have been built, and how their impressive life-span claims rarely stack up to reality.

Because we ve managed to get such an even distribution, we don t need diffusers — which cut the efficiency by about 25 per cent.

The LED has a 60-degree angle on it, so that little yellow phosphor blob acts as a lens, but there s no side-spill because of that cone.

Because that LED is cooled to its absolute peak performance, and is operating at the ideal efficiency, Dyson says, you get more light — and you can run that light for four, five, six times longer than a competing retro-fit product.

Rather than a space lit with a grid of criss-crossing downlights and direct overhead lights, Jake says, the ideal lighting for any room is a combination of indirect lighting — upward-firing lights, reflecting off a ceiling and distributing luminance evenly around a space — and task lighting, focusing on the job at hand, whether that s a kitchen table or a sofa, or an office desk or a corporate boardroom table.
