Articulated LED Map Light Conversion - V2
The first step, as always. is to add as many
wires as possible. Here I am only getting started. Each circuit requires
six wires (and there are now two uController circuits) plus the individual fixture
switches require a couple of wires each, and then there are all the power wires
that need to go to the correct places. Not to mention the jumper wires that
put the emitters in series. And on and on. Soldering is fun.
Here is the inside, behind the diffuser. Both
off and on The Luxeon Stars are thermally bonded to a round heat sink, and a
custom reflector is added just for grins.
Below are two shots of it completed and installed.
In addition to the two 1W emitters behind the diffuser, there is another 1W
emitter in the aimable reflector head. The fixture lights are controlled with
the driver-side fixture button, and the articulated "map light" is
controlled with the passenger-side button. When the map light is used by the
passenger, there is no spill into the driver's eyes. One of my main criteria!
As I have it set up, the door switch turns on the fixture lights only, just
like in stock form. All emitters are dimmable, and will auto-sleep if left on.
There is really no way to run the battery down by leaving a door open or a switch
