250mm Moon Lamp

I encountered a captivating moon lamp in a brick-and-mortar store—a design by the eminent Danish architect Verner Panton dating back to 1960. By adjusting its vanes, the lamp subtly shifts between brightness and shadow, mirroring the lunar cycle's phases—a truly enchanting effect. The original design only came in 420mm and 350mm diameters, rather substantial sizes. I therefore created a scaled-down 250mm version, perfectly fitting my build plate. This more compact size makes it ideal for a bedside table or as an ambient light.

During assembly, carefully observe the order of the washers on the solid shaft beneath the lamp. Each vane has a unique angle, and the washers act as limiters, allowing for progressively greater rotational freedom from the outer to inner vanes. Each layer of washers where the wires pass through the upper section should include an added TPU washer, primarily to provide rotational damping. If TPU isn't available, a substitute material can be used, but an additional washer is imperative to maintain the correct height.

Print configuration one utilizes washers of uniform height for both upper and lower sections. The original design, however, features a denser arrangement at the top and a more spaced-out arrangement at the bottom. Both the washers and connecting shaft can also be printed using configuration two, resulting in a slightly easier assembly due to a shorter lamp wire shaft.

The lamp uses 2*0.5 wiring with a 5.2mm outer diameter. The lamp holder is a G4 ceramic type. The bulb's wattage and color temperature are entirely customizable to personal preference; however, only LED bulbs should be used. Halogen bulbs generate excessive heat, potentially causing the lamp to warp.

Print configuration three provides a modified top cover suitable for recessed lighting fixtures. It allows for conversion from a built-in (recessed) lamp to a pendant lamp, compatible with openings measuring 60-90mm.
