Final Project
We were generally interested in light properties, such as pattern, refraction and diffusion, and our process was an exploration of light as an emotive vehicle. I think we were in successful with using Plexiglas as the medium, but adding the second layer of the street lamp reflector was criticized. We thought we were going to get more refractory patterns, but instead it diffused the light, and we lost the animated patterns against the wall and ceiling.
James N. Sears designed 4 arrays of a set of 8 Lumiled lights. Each light array was blurred and a part of a quadrant that was translated from the simulation:
We stopped the computer simulation and noted the colors in each array and quadrant. This diagram was important for soldering power and ground wires.
In quadrants 3 and 4, three cyan colored LED lights are required, but when we ordered the cyan light, it emitted a green light, so we had to come up with a solution of mixing colored lights by additive color mixing.
Unlike paint, mixing light required an additive Color process, we had to consider:
+ Superposition (Lamp Overlap)
+ Rapid Alternation (biased LED) "persistence of vision"
+ Small Elements (TV Pixels, Halftones)
Red + Green = YELLOW
Green + Blue = CYAN
Blue + Red = MAGENTA
Red + Green + Blue = WHITE
Original pattern of lights computer simulated:
Lumiled Light patterns soldered to PCB board:
These are the patterns we cut into Plexiglas to make our lens.
We strung 72 pieces on two steel threaded rods.
