interesting article to share. thought it be a good read
The main hi/low unit has 56 leds…I wonder what kind of emitters?
I still like the Porche.
The 2008 Audi R8 was the 1’st car available with all LED headlamps. The Audi A8 has also had them for a couple of years now.
Nothing against Mercedes, but Audi has lead the way globally with automotive LED applications…
Laser headlights
so lets assume 251lm/w is the theoretical max (100CRI), in 2011 the best LEDs could only do 0.251 lumens?
even 1000x an incadescent is 17600 lm/w, meaning free energy (perpetual motion machine)
so lets say not lumens/watt but max intensity available
I’m not sure what the brightest led was in 2011, but i had an XP-E that could do over 75 lumens/watt, so 1000x means 75000 lumen output from this device. I assume that means an alternator upgrade, lets hope its compatible with my mr fusion.
I hope they drive them with high enough frequency this time. Those common 200…400Hz automotive backlights flicker to much in the corner of the eyes, very annoying . . .
True however based on the federal rules as they are now, we wont see cars with full LED equipped vehicles on the road anytime soon in North America.
In some States, daytime driving lights are still not allowed. It's a grey area and until the rules get updated to the new technology standards we're still left with old tech lighting.
The beam shaper is pretty neat, especially how it wraps the light around the car in front.
i agree!
Can you explain this to me? I am curious on how this works out.
i was saying that if you can’t go above 251 lm/w at 100 cri (color rendering accuracy), and if the claim of 1000x brighter then leds is accurate, then an led could not provide more then .251lm/w, which we know is incorrect, therefore the 1000x claim is garbage.
I don’t think they mean efficiency, probably point beam intensity/surface brightness. They may not even be taking power consumption into account.
I like the Laser solution much better.
in that case you would have a laser not a headlight, and somehow i don’t think that would be legal as you would be blinding every pedestrian for life
Laser lights are legal and are already in use on some models, it won’t blind anyone cause the laser light doesn’t go directly out the lens, rather it is a blu-laser reflected off of phosphor coated optics.
Nope, it’s a federal regulation and state laws can’t trump the feds…
good, then i don’t have to avoid those states :bigsmile:
I'm wondering more than that since it appears to be behind a single optic.
Your title is not quite the 1st….
Actually the Merc is the first to have ALL LED lights for every light inside and out, not just headlights.
“The S-class will be the first car to use full-LED lighting. Totally rid of hot filaments, the sixth-generation S-class sedan will instead be fitted with 490 LEDs filling all lighting, signaling, and interior-illumination roles.”
