Artificial sky

The concept of the artificial sky was derived due to heliodon’s limitation in providing a stable lighting environment for evaluating the diffuse skylight component.

The instrument is utilized to examine the visibility of tools in the cockpit in automotive and aerospace engineering to improve flight safety.

[1] Generally, interior daylighting of buildings is analyzed at the design stage using physical models by observation and evaluation of physical models of light levels under a real sky, but the luminance is constantly varying, and regular results are difficult to obtain, therefore artificial sky forms the ideal way to predict daylight penetration.

To address readability issues that arise due to glare and faded screens under ambient lighting conditions in automotive displays, artificial skies provide a luminous environment that allows designers and engineers to handle any areas of concern.

The use of simulation aids in avoiding glare and reflected heat from building's facades mainly due to innovative design forms.

The simulation device will allow designers to avoid unexpected events that occurred in concave surfaces of the Walkie Talkie skyscraper and Walt Disney Concert Hall where it caused damages due to reflected heat and glare.

[5] The walls of the room are surrounded by plane mirrors organized vertically on all sides, which produces an image of the luminous ceiling by reflection and inter-reflection.

The artificial dome uses a reflective surface to illuminate sky distributions and evaluate daylighting on scale models placed on a rotatable tabletop.

Compared to mirror boxes, reflecting dome skies are more adjustable in utilization and their variants are widely available in the market.

To limit cost and space, the virtual dome utilizes heavy robotic and fine control systems.
