DIY LED Car Lighting

Takky presents an interesting method of making inexpensive LED car lighting:

Wow, that's impressive. Don't understand why it needs an additional diode besides the diodes in the bridge rectifier, but the results speak for themselves!

Love the symplicty of the physical design. Very Japanese in the packaging.

Cap'n

 

The bridge rectifier converts AC to DC and the second diode is a CRD to regulate the current.  The capacitor, I guess, is to reduce flickering.  But I'm sure I've read other reports on this forum suggesting that larger capacitors are required.

 

The project is interesting, but I'm time poor.  I'll stick to manufacturer's kits.

Given the size of the capacitor, it's probably a noise filter required by the CRD rather than for flicker-reduction. I've never worked with a CRD though, so I don't know anything about them.

 

But I'm impressed by the approach to building them.  I'd never thought of using double-sided tape to hold things in place while soldering leads to leads. And it clearly works for mass-production.
