In playing with the Philips Hue system, we found wireless controls to be an effective means for solving lighting issues we have around the house. One area is the main stair. While the overhead track lighting system does a fair job lighting the art on the walls, it is a bit much when all we want to do is have a little light to navigate by. I also wanted to have the light turn on and off automatically, to provide a level of ease, and to get rid of the issue of forgetting to turn off the stair lighting on the way to bed.

Applying a wireless light, programmed to turn on-off and dim is a great addition, and an opportunity to create a new fixture while I was at it. The added feature of color changing to suit the lighting mode is a serious bonus and a lot of fun. Since the light from the stair itself is visible through a window facing the street, the effect of color here creates an interesting effect from outside as well. This design explores printing translucent materials for creating the shades, in addition to printing the rest of the fixture from ABS overall. The design itself is a bit freestyle, mixing a little Art Deco with Hi-Tech, influenced a little by American Indian… The light source is the Philips Hue A-style lamp, which has been modified through the addition of a bottom shade closure to hide the light source from below. The challenge with this design was to hide any direct view of the light itself, as at night the brightness was too great. I would like to have eliminated the cord connection, but tearing the stair railing apart to drill a wire channel through it was not on the agenda.

The 3D printing process (FDM) adds texture to the shade material.

Now, we let the light run its program, and don’t have to remember to turn things off when retiring. We can also use the light to create a visual presence when we are out and away by setting different on-off times, color effects, etc… which from the outside, looks like things are moving and changing inside.

Deco-Tech is the best I can come up with to describe the design vocabulary used. It's really just freestyle.

Interesting note about color in this application. The very low blue light level makes seeing things in the stair when no other light is present very easy, so the level can be set low. Yet, this setting is easily ignored, and does not feel like a light on in the hall. I’m not concerned about the blue color interfering with sleep or melatonin suppression in this application, simply because the total energy we are talking about is so low (<.1 Fc).

Unfortunately, digital cameras have a hard time dealing with saturated colors, so this photo fails top show what this actually looks like (blue lighted portion). You can get the idea though, and having it cycle slowly through different shades is very pleasing.

I was hoping to get a better image of this with the setting at 2200K and some saturated colors. Unfortunately the camera is fighting me, so I’ll just leave these with you to suggest how the fixture looks in other than white settings.
