A simple fresnel construction with addressable warm-cold-amber LEDs to cast a pattern to ceiling, where the individual LEDs communicate status from a data stream.


Based on the underlying paradigm of “Expanding Creative Coding Spaces,” a chandelier was developed that captures specific color values from visual effects generated in P5.js or Processing and translates them into an abstract, spatial light visualization.The RGB color space derived from the captured pixels in P5.js/Processing is translated into WWA LEDs. This means that each RGB value—for example, red (0–255)—is mapped to amber (1800–2000 K), green to warm white (2700–3000 K), and blue to cool white (6000–7000 K). While this approach does not allow for representative color rendering in the traditional sense, it creates a distinct color space focused on the white spectrum. Compared to the artificially additive white tones produced by RGB pixels, this results in a lighting effect that appears more natural in the context of ambient room illumination.The chandelier contains a total of 60 individually addressable pixels, enabling 45,900 possible individual color combinations. These light points are projected onto the ceiling above via a Fresnel lens, creating the chandelier’s characteristic light visualization.The underlying P5.js/Processing sketches are transmitted in real time to the chandelier via the Art-Net protocol. However, the original visual content differs significantly from the physical light projection, as the Fresnel lens introduces a strong abstraction. This transformation generates a unique aesthetic in form and motion, depending on the lens’s position and angle of rotation.
