LED Angel eyes - Auto dimmer
 
Ive had this idea to make an auto dimmer for the LED angel eyes
heres how my testing has gone so far.

Im going to eventually make a sealed box with the LDR inside with a fiber optic feed for the light.

my test module:

Output in the shade:

Output when dark:

Output with direct light:

This is obviously still in testing.... still need to get some orions so that i can output a final product
Lemme know what you guys think of this idea.

Wow, very nice! Cool idea.

Are you talking about the new Orion LED angel eyes, or the older syle ones?

freerider 04-09-2008 11:14 AM

the new LED orions... im not sure how the voltage drop would affect a ballast on the CCFL's

Predator Orions; can fade with the interior lights naturally as part of our kit.

The LED we spec'ed are not like the ones you are showing there though.

i realize that, this is meant to make the angels eyes dimmer at night than they are in the day.

also know that the LEDs in the angel eyes are different but for testing purposes i bought elcheapo highbright whites

definitely, my main argument against these is their brightness. id love to see something that could work like you're showing

Great idea, an even better addition would be the use of a light sensor for auto switching of higher/lower voltage.

Edit - saw your thumb covering the sensor, you're already a step ahead. :)

Yeah thats what i was aiming at, They look really nice in the day light but i wanted to tone it down when it got darker outside :P

What is this meant to do???
 
There seems to be some confusion here, let me clear it up.

This is not meant to fade the angel eyes in or out when unlocking or locking your car.

This is a to dim the angel eyes at night to retain the halo look and return them to full brightness during the day, with the use of a light dependant resistor the angel eyes will gradually get dimmer as it gets darker outside and then brighter as it gets more light.

I'm just having a bit of trouble sourcing fibre optic cable :(

very neat idea... :)

why do you need fiberoptic cable? For the photosensor?

yeah was going to use fibre but have now decided against it and am looking at another solution. fibre doesnt get nearly enough light through

new orion angel eyes :drool:

Actually, you should look into using the OEM photosensor. :idea: On my US spec 330, there is a photosensor next to the dash light dimmer on the LCM. Maybe you could figure a way to tap into that.

yeah, my next question would be how would we mount the light sensor? in the hood grill by the windshield squirters would be good out of ease of routing

yeah thats what im thinking as the unit will sit in the same compartment as the relay for the angel eyes so its a short route out near the wind shield wiper spray and that way it is out of sight,
I just need to find a clean way of mounting it now.

Im also going to be putting a variable resistor into the circuit so that the dimming effect at night can be fine tuned according to personal taste.

wow awesome idea!! def keep it up

dmisc 04-11-2008 04:26 PM

Very good idea...Are the Orions that bright for the night? Or is it just preference?
