The decision: making a wall lamp

After a few sleepless nights I finally decided to create a wall lamp, because the concept of replacing a picture on the wall with a lamp is very interesting. Like I already said, many people connect a wall lamp automatically with an outdoor light, small, cautious and simple. This is where I see the challenge. As the lamp replaces a picture, it needs to be as eye-catching as the picture. This is where I come across many questions:

What is needed to get a new impression of wall lamps?

Should the lamp itself be exciting?

Should only the light be exciting?

Is it a good idea to design the lamp as an „picture look-alike“? (with a frame, square,..) …

Material

As I want to do something with reflection and/or transparency I came across a wonderful material: Dichroic glass!!!

Dichroic (meaning two colour) is an optical coating that selectively reflects certain wavelengths  of light and allows the remaining wavelengths to transmit through. With this clever use of light, very exciting shadows and light reflections can be archived. In the following there are a few examples using this material, colorful geometric glass installations by Chris Wood​, found on his website.

I think using this kind of glass for the wall lamp unites many aspects: due to a high degree of transparency it can be shown that no converter ​is needed for the LED to shine. Furthermore there is a lot of movement and excitement going on with the lamp even in its turned-off mode, so the concept of replacing a picture is fulfilled, because pictures are the most exciting with lights on. With the dichroic glass the lamp will become a 24 hours excitement!

Next steps
​Playing with and trying out dichroic glass. While diving deeper into the subject, I found out that there are lots of different types of glasses, from warm to cold colors, rough or smooth surface, etc. The easiest and cleanest way to approach the task is to work with foils that can be sticked on a glass surface and have the same effect as the dichroic glass. Therefore, I ordered two different kind of foils that are usually used for buildings to get interesting glass walls. I am now dyingto see how they will look like!
