Natural Daylight

New S2G+ Offers a Realistic Sky with Stars

Daylighting with LEDs is changing every aspect of architectural design, allowing spaces far from exterior walls and ceilings to bask in the healthful and productivity-enhancing glow of natural lighting. But what happens when the sun sets? A real window to the sky would of course transition to a night view of the local stars, so […]

Virtual Skylight vs. Tubular Daylighting Devices

The Virtual Skylight (VS) is not a luminaire in the conventional sense and is best compared to Tubular  Daylighting Devices(TDD) such as the Solatube and the Sun Tunnel. I have rounded up a comparison sheet so that one can better understand the differences, using the Solatube 290DS and the Flotonix VSP Virtual Porthole 290DS    […]

GE C-Light offers circadian control

In a move towards healthier lighting, GE is now offering the C-Sleep bulbs with BLE connectivity and an app called “C by GE”. link There is a follow the sun option with three color CCTs and three switch times defined as AM, DAY and PM. Apparently AM starts off with a very high CCT, which […]

tiling daylight

The 1 foot square virtual skylight is meant to be tiled in arrays of 2×2, 3×3, 4×1 and so on. Each tile is controlled via wifi and BTLE to coordinate a simulated sky with brilliant blue color and tunable white light. Set the location and time and forget it; from then on the VS will […]

Natural skies are non-uniform

Because natural skies look more like the picture on the right, a simulated sky such as in the virtual skylight benefits from a single lit edge. The unique Evonic material in the vs allows color stacking so the ideal design might place a warm 2700K edgelit panel on top of a 6500K panel lit from […]

Daylighting LEGOs and a virtual sky cupola

Virtual Skylighting is about to take a new twist: stackable daylighting LED rods that connect together like LEGOs. This will allow these thin rods of tunable white to be arranged as an assembly of up to six per power supply/battery pack. Imagine a circular arrangement of these around an interior cupola: at dawn the easternmost rod begins […]

Virtual Route

The beauty of a sun controlled luminaire such as the VS extends beyond the health and productivity benefits. For example, if you wish to turn the light on to maximum and to have that continuously you would open the phone app and set a virtual journey, one that follows the sun throughout the day and […]
