The project created a physical simulator that demonstrates the effects of light pollution on the starry sky and the difference that well-designed lighting can make. The simulator consists of a LED-based model board simulating the starry sky and several LED model light fixtures. The board simulates the night sky using LED’s of variable brightness, simulating stars of various magnitudes and constellation patterns. The board is illuminated by the light fixtures and users can use buttons to switch between light fixtures as well as increase or decrease light intensity. This creates a first-hand experience for demonstrating the effect of light pollution as different light fixtures have different effect on the number of stars visible.
The simulator can be used in exhibition halls, conferences, science museums or any other venue where light pollution effects need to be demonstrated.
Detailed instructions are available in the attached report and website, including construction, assembly, coding, to construct the simulator.
