I’ve been bashing my brains all day thinking about lighting fixtures. One thought is that lighting fixutres are closer to pure sculpture than anything else I”ve made. They don’t require lots of internal structure (say, to hold up a tabletop, or a seated human), and they have to let light out. That’s really it, in terms of hard requirements. LOTS of options. I’m adding a little bit of lighting porn to this post - stuff that I love. But both of the fixtures that I love aren’t terribly good in terms of actual lighting - they’re quite dim, really. (One is Greene and Greene from the Thorsen house, and one is a 2/3 scale Frank Lloyd Wright replica by Prairie Designs) .
So. The design I’m working on now is something that would work well with the LEDs. This means it needs a heat sink, which is a bit of a blessing. The more constraints there are on design, the easier it is. I’d like to make a round lampshade, and it would be nice if it were semi opaque. To offset all the maple, glass, and metal in my kitchen design, I’d like it to have a warm tone, and round is good. Where the heck can I get a round red glass cylinder? I was going to use bottles; bottle cutters are readily available. But I think the real answer is that I’ll need to re-purpose some glassware. I’ll spray the inside with a translucent white paint (so it’ll reflect white, and only show minimally from a side view). Mount the whole thing around an aluminum disc for a heat sink (more than adequate - a 2 1/4″ diameter sink will support a 4 watt Luxeon K2), devise a support for the whole thing to hang together, and that should do it. Now, I need to find a source for aluminum discs, and hope that the bottle cutter does what I want it to. I’m also a little iffy on the paint - needs to stick to glass, and be thin enough to be translucent. Hmm.
