Intial Research

How can we make spaces without access to natural light livable, comfortable, and more desirable?

Older appartment buildings in urban environments frequently have rooms with one window that have little access to the sun.

Humans evolved to look at warm tone sunlight, resulting in

  • Lower Blood Pressure

  • Increased Seratonin Regulation

  • Large Reduction in eye strain

  • Improvements in quality of sleep

  • Reduced risk of dementia

User Profile

  • Design concious urban dweller, likely higher income working in a creative proffession

  • Lives in old construction appartment building as a permanent space, not transient

  • Sacrificed natural light in exchange for the appartments neighborhood

  • Older building has lack of outlets

Ideation

I was inspired by industrial honesty as a way to highlight the technical complexity of the lamp internals

Originally, I was interested in organic curtain like forms to serve as a representation of a window

design a wall-mounted, battery powered lamp which recreates the positive effects of a window.

Sunlight Specs

To recreate golden hour, I would need to achieve the following

  • a temperture of approximently 2800K

  • a color rendering index of 100

  • an angle of 22.5 degrees

  • parallel, laminated, light rays

Initial cad model to get sense of scale, no component on final cad model was repeated

Building

and

Assembly

When calculating the angle of reflectance from the mirror, I unknowingly flipped the sign of the negative tilt coming from the lens, resulting in light being projected upwards, not towards the floor.

Luckily, by simply inverting the lamp, the light was directed correctly, and a once top heavy design now looked grounded. This orientation was then used for my final design

Final CAD Build

The heatsink was milled to have threaded cutouts,
M3 threaded rods were cut and chamfered to size,
Lens assembly was assembled

Final Renders

All renders done in Keyshot

Solutions


  • 2800K 1000 Lumen COB LED with

  • a color rendering index of 98

  • a mirror tilt of 15 degrees, and a lens tilt of 1.25 degrees to create projecting angle of 22.5

  • Fresnel lens laminates diverging rays to make shadows crisp

As I kept sketching and refining the internals though,
I made the decision to celebrate the electronics, shifting the project to an industrial aesthetic

Learning moments from Prototype

3 different tolerances for the battery compartment and cap before the perfect fit was honed in.

Flexible conduit was cut to size,
Final assembly

CAD Development

PMMA Cast plexiglass was laser cut,
flame polished and buffed using toothpaste

Final Images

More advanced model, testing a wavy front geometry versus the rectangular shape I decided upon.

Internals and CMF were also further refined past this model.
