Going to build a approx. 10 W LED (ridiculously bright) light for my bike. Interesting, and perhaps unique features of my light:
- Strong thermal connection between LED/Driver, entire housing, AND bike. Most lights don't seem to take advantage of the fact that the bike can sink some heat too - using plastic mounts, not-very-conductive-looking paths to the mount. Face-plate and upper bar-clamp will be 1 piece aluminum (2" square bar or 2" hex bar).
- Uses recycled (free) Northbridge (from a PC motherboard) heat-sink, that packs a lot of fin area in a lightweight package (>20 sq. in, 1-5/8"x1-5/8"x1", <40 g).
- Should be easily machined with access to files, band-saw and drill-press (so, no lathe or mill required)
Here's a concept sketch, a picture of the LED/Driver module I've ordered, and a picture of a Northbridge heat-sink:
