This is the realization of a desk lamp very simple, functional, with adjustable brightness and ... low consumption.

As you can see from the photos I started with a piece of aluminum profile, I folded, I glued the two strip and I fixed them with some point of component epoxy resin, I made the wiring harness and realized the small printed circuit board that see below in the photos. For materials see the "LEDs driven in PWM"

See the wiring diagram below.

The. HEX file is the same as the project "Led driven in PWM", at the bottom of the datasheet.
