My W30 fell apart

Old djozz experiment:

making a reflective ring on a XM-L led-dome by silver deposition

I like to experiment, and was thinking of trying this for quite some time. A few weeks ago I did the actual experimentation, but the results were a bit disappointing so I hesitated doing the write-up. But I believe it is just fair to not just report your successes, but also the failures, and it involved quite some work, so here we go The idea was to deposit a silver layer directly onto a led-dome, to accomplish that the light going sideways (and is lost when the led is used in a aspheric le…

Some more discussion from a later reinvention:

Painted collar

Long time ago I’ve seen someone come up with the idea of painting a collar with reflective paint directly on a LED dome. I’d like to theorize on that topic… Let’s first depict the subject in question: [image] Both LEDs that you see are actually the same model. But they are depicted at different angles, one is straight and the other is rotated by 45°. Let’s call the green angle α and the red one β. Let’s call the orange angle γ and the violet one δ. Let’s call the lens collection angle ε. …
