Would this result with an increase in energy efficiency in any way? Xenon consumptions vs. LED? Or is this just so small to be significant?
What would the practical advantages of LED headlights also be over Xenons? I basically don't know much about cars besides my interest in EV drivetrains and batteries I guess haha.
And the fact that there are gaps between the headlights and the hood. I believe the hood is final but the front bumper and headlights are not.
Couldn't you tell just from looking at the non-camoed part though? (If the rumor is full LED headlights and not just accents...)
Hopefully, they'll have an OLED option for Model 3. Those are as malleable as it gets.Efficiency is a benefit, sure. How much, I don't know. The power of LED lighting vs. Xenon depends, in some cars it is about the same, in others it can be better or worse.
One benefit of LED lights, as they are formed of many small lights, is the ability to generate intelligent patterns - Audi for example combines LED lights with navigation data to generate different light patterns for intersections etc. A downside in some LED implementations I've seen is lack of headlight swivel, which Xenons often use to point the lights intelligently depending on curvature and load.
As an emotional issue, I think LEDs just "fit" an EV like Model S better. Xenon reeks of ICE age to me.
I think the ideal solution would be a grid matrix of LEDs, maybe 10x10. If you put these behind a lens you could then steer the beam extremely accurately. LEDs could vary from 100% brightness to off and could steer the light pattern where you need it. I should patent this idea if it hasn't already been invented.
A normal high beam might only use the middle 8x8 portion of the array at full brightness. As you enter a curve the active 8x8 portion could move left or right to steer the beam.
