Would you mind going over all of the components of a lighting system like your planning? I never knew so much went into it and would love to learn more.
Now, pay attention
I'm pretty new to all of this, but my amateur-level understanding is that a projector system is really quite simple; you basically have wiring
, a bulb
, a power source
, a projector assembly
, and a housing
. The wiring
is the simple part; like any other headlight or bulb, you just need to run wires of the appropriate size in order to deliver the needed amount of current...but that's where the similarities end, because the heart of the projector system - the gas arc bulb
- doesn't work quite like a normal filament bulb. A gas arc bulb needs a power source
- a ballast - in order to give it the correct amounts of power at the correct times, so when power is provided to the ballast it 1) provides the current necessary to power on the bulb, and 2) regulates the amount of current necessary to continue
powering the bulb. You can read up on the esoterica of this process if you like - here's a link
- but the important thing to understand is that once the gas arc bulb is lit you're good to go as far as light production
is concerned; light direction
is a different story.
In order to direct the massive
amount of light that a gas arc bulb produces, the bulb itself is housed in a projector assembly
that consists of a reflector behind
the bulb - we all know how reflectors work - and a condenser lens that's in front
of it; these two components basically catch all of the produced light (reflector) and direct it forwards in as linear and orderly a fashion as is possible (condenser lens). That's really all that there is to a projector assembly; the only other major important part is a solenoid-activated shade that alternately blocks or reveals part of the projected light from the bulb in order to create low beams or high beams. The entire projector assembly is placed in a weatherproof housing
, and this housing is literally nothing more than something to hold the projector assembly stable within whatever mounting and alignment system the vehicle uses.
That's all there is to it; power is fed to the ballast, the ballast kicks on the bulb, the bulb's output is directed by the projector assembly, and the projector assembly is contained in a sealed housing. You can buy all of the parts and pieces as a kit
, and as we've seen it will bolt right in to a TJ.
Is that a good explanation, or did I make it worse?
