Laser Headlights Promise More Intense, Controllable Beams

Soulskill posted about 7 months ago | from the but-you-better-not-aim-your-car-at-planes dept.

Transportation 376

cartechboy writes "Soon, your new car's headlights will be powered by lasers. The 2015 BMW i8 is entering production, and it's the first vehicle to offer laser headlights. These new beams offer a handful of advantages over LED lighting, including greater lighting intensity and extending the beams' reach as far as 600 meters down the road (nearly double the range of LEDs). The beam pattern also can be controlled very precisely. Plus, laser lights consumer about 30 percent less energy than the already-efficient LED lights. Audi is among the short list of other auto manufacturers to promise laser lights in the near future. But the coolest part of all this? When you turn on a set of these new headlights, you'll be able to scream, 'fire the lasers!'"

This would indicate the FBI is still interested in law enforcement, which is incorrect. You see after nurturing organized crime for the purpose of job security along with an undocumented bonus program (because there's money in the mob) to be an out of control institution they ran off to play spy and changed their drama theme to be national security. So what makes you think they'd give a rats ass out of lasers and aircraft? Me thinks they'd be more interested if there were sharks with laser beams and aircraft.

jklovanc (1603149) | about 7 months ago | (#46226617)

Laser pointers are quite different than laser headlights.The key is divergence. A laser pointer is tuned to spread out as little as possible with distance and can therefore be quite powerful at long distances. A headlight, through the use of dispersing phosphors and or lenses is designed to spread out and cover much more area. Illuminating a 1/2 inch circle 600 yards down the road is not much use.The key is that laser light is more controllable. Perhaps directing more light lower down along the road. Laser headlight will use a laser initiator but when the beam comes out of the headlight it will be far from cohesive.

I doubt that (1, Insightful)

Anonymous Coward | about 7 months ago | (#46226649)

I am quite certain these laser headlights will be brighter and more blinding than even the current too-bright headlights are, regardless of what you say.

Re:brighter? (3, Insightful)

tgv (254536) | about 7 months ago | (#46226741)

Yes, indeed, but you've already mentioned the main problem: "quite powerful". If the light is more concentrated, it will also be more concentrated when it hits the eye of the driver in the other direction.

Re:brighter? (1)

Anonymous Coward | about 7 months ago | (#46226881)

If a car drives over a bump and a nearby pedestrian with fully open iris looks into the light, there is not that much distance for the divergence to spread out the power. If someone uses a telescope to spy on animals in a forest and suddenly such a car shines on him, much more power is collected by the large first telescope lens/mirror.

Re:brighter? (0)

Anonymous Coward | about 7 months ago | (#46226933)

I'm also concerned about intersections and crossroads. One of the, shall we say, features of current headlights is that they project a wide(r) beam, which I find to be useful when approaching an intersection or crossroads (at night, obv) when I can't see other vehicles approaching, but I see their lights reflected on the road. No matter who has the right-of-way and who has to yield, it's always good to be aware of the other drivers on the road.

Another case might be, at a roundabout when I don't have direct view of traffic on the other side, I can still see the "backlighting" on the obstacles between us. It seems "they" like to put little gardens and sculptures and stuff in the middle of roundabouts, which then to limit your view of what's on the other side; I'm not saying it's an entirely bad idea, but I like to have some info on where other vehicles are on the road.

A headlight, through the use of dispersing phosphors and or lenses is designed to spread out and cover much more area.

What if you get into an accident that destroys the outer housing of the light (containing the dispersin phosphors and/or the lenses) while leaving the source intact?

So you've got a "deathray" shooting out from the accident scene wanting to involve more cars, until somebody turns it off...

This, aren't headlights bright enough, what they need to do is to illuminate more of the road and surrounds (as in the side of the road where people jump out in front of cars from).

Instead now I'm going to have a BMW prick playing with his lasers as he pootles down the highway either doing 20 more or 20 less than the traffic.

Re:brighter? (0)

Anonymous Coward | about 7 months ago | (#46226713)

The biggest problem with the wave of trendy headlights on cars is that they're not warm-tinted. It not only causes problems for oncoming drivers, but requires a longer time for the eyes to adjust should the driver or neighboring drivers need to see outside of the area lit by the headlights. Hopefully if these laser-based ones are strong enough, manufacturers will filter them.

Roshan Halappanavar (2994663) | about 7 months ago | (#46226733)

I doubt if any OEM is planning on using lasers directly to illuminate the road. I remember Audi introduced a concept at CES 2014 with laser headlights and a similar debate had ensued then. I work for an auto-OEM and I can tell you that all cars are aimed to avoid the beam going UP i.e into other driver's eyes (unless he's in a go-kart or something.. Ariel atom maybe???). There's not much that can be done when someone gets the headlight reaimed higher which is never recommended by the OEMs

This article http://spectrum.ieee.org/green-tech/advanced-cars/bmw-laser-headlights-slice-through-the-dark(ieee spectrum) shows the actual working using very powerful but very small laser beam which is then diffused into a headlight's non-laser non-coherent beam. The only advantage of this is that a higher power level can be achieved with a very small form factor (smaller reflectors at the back of headlamps means lower costs) which is why OEM's are even trying it out.

... (unless he's in a go-kart or something.. Ariel atom maybe???)

Not necessarily: passing over the top of a hill, your headlight beam will be above the incoming traffic. Going down, there will be a moment when your beams will shine straight in the eyes of the drivers in the other lane.

Not blinded by laser but blinded nonetheless (2)

aepervius (535155) | about 7 months ago | (#46226753)

My understanding is that the laser is used to pump energy efficiently in a light emitting substance, thus making it a classic point light which expand spherically. They are not using laser directly to light the road which would be pretty much useless (you want a rather wide cone to show the whole road and a bit on the side).

Nonehteless I am betting such light would be forbbidden in many country in europe where the maximum intensity you can pump is limited by law. And rightfully so, the "normal range light" are okish but the "long range" light are already quite blinding, and usually leave me blind fully for 3 to 4 seconds when one is oncomming and forgot to switch back to normal range light. I can't imagine regulator allowing even more powerful long range light being able to light everything on 600m.

BMW being a European company will take those limits into account in their production vehicles, don't worry.

That's another matter. It's for a reason it's called "dipped" resp. "blinding" light. Now the problem for some areas, like what I see happening in China all the time, is that everyone likes to drive with blinding lights on at all times. I don't understand why - the result is that no-one can see anything properly. But then, it's not that those Chinese drivers care much about what's going on around them anyway...

absolutely, what I hate the most are the super brights on large SUVs when I'm driving in a smaller (lower down) car. there can be big distances where I'm completely blinded as the light is near my head level.

It gets even worse in europe where you have cars with RHS and LHS drive on the road (usually, headlights in the US have a slight angle to the right so your left headlight doesn't blind oncoming traffic as much).

The last thing I want is even brighter headlights. If current ones aren't bright enough for you to drive safely, you are driving too fast for your skills.

necronom426 (755113) | about 7 months ago | (#46227011)

I hate those horrible blue lights that some cars have these days. They are blinding. But worse, are the back lights that strobe! They are more dangerous than the headlights. I have to look away from them as they freak my eyes out. So I end up driving along behind a breaking car looking away from the direction I'm going in! How are these allowed? I'm thinking of getting a new car soon, and one of the things I'll be looking at are the lights. If it has LED lights at the back, or the blue blinding lights in the front, I won't consider it.

These laser ones sound worse than the blue ones.

Re:At what replacement cost? (-1)

How adorably naive. A lightbulb is solid state as well, the electrons are conducted in the filament, and the last time I checked tungsten is a solid. And guess what? Semiconductors wear out as well, especially when they're working with great energy densities.

But this is all moot, because 3D printing is the future and when we 3D print entire cars, by default it means we'll be able to 3D print the laser headlights. If there are still any weird DIY Luddites out there who still want to repair their old car, they can 3D print a new laser headlight.

Of course, by then we'll just 3D print new cars on a whim, since 3D printing will be the last technology we'll ever need, indeed invent. It's the Eschaton, the Singularity, the future.

Alioth (221270) | about 7 months ago | (#46226987)

Some safeguards and cutoffs that failed safe and prevented disasters:

- Countless runaway trains have been prevented by failsafe brakes (vacuum in the early days, air brakes today).
- Countless boiler explosions prevented by safety valves
- Several nuclear explosions prevented by failsafe arming mechanisms when the bomber carrying the nukes crashed.

There's three. The thing is you only get to hear about the failures. A failsafe working and preventing a disaster is not news so no one ever reports it. But I can guarantee you every day dozens of industrial disasters are averted by failsafe devices like safety power cutoffs, pressure activated safety valves, braking systems that come on when there's an air leak, signalling systems that fail to "stop" when there's a system failure etc.

If we had your attitude we'd still be insisting a man with a red flag walk in front of every car.

It's a laser illuminating a phosphor. First guess is that the laser is not designed to/doesn't have to stay in a tight beam for more than a few milli- or centimetres.

The author of the article doesn't seem to be well-informed about the current state of LED technology. There are flashlights with a single emitter that can cast a beam over 900 meters.

Wrong idea.

The lasers only illuminate a phosphor emitter, which then produces the actual headlight beam. No laser light is emitted at all. It's more akin to the way a CRT works.

A thousand internets to the first one that figures out how to make the lasers scan the phosphors CRT-like to produce projected video. Stuck behind a semi for miles at night and bored? Just project a movie against the rear of the trailer ahead of you with your raster-capable headlights!

Some guys already tried that, for a different reason. They mounted a projector in a car to act as headlight, and added a camera to track raindrops as they fell through the beam. A computer then predicted the path of each drop and made the projector not illuminate that bit, giving a much clearer view ahead during nightly rainfall.

Que the people whi argue that "this will cause people to drive much faster in unsafe conditions!". They said the same about seat belts and airbags.

Laser headlights + digital enhancement (1)

austinhook (656358) | about 7 months ago | (#46226599)

More interesting would be any kind of headlights, that don't blind the driver coming at you and are digitally enhanced so that with some kind of viewer, you could see the road ahead of you all night, as clear as or better than day.

I'd pay for a good monacle or system that would let me
a) spot the cops and alert me
b) send me alerts from systems in a kilometer or two that also saw
them (so i dont have to rely on idiots like you who never bother
to flash your lights while driving to alert others and save them a
useless ticket) (or worse, were so damn buried in your phone that
you never saw the cops).

It's not my social responsibility to ensure you don't get a ticket because you're a fucking moron.

I've wondered if polarized headlights would help, because you could then have a filter on the mirrors and windshields to block direct light from the headlights. Most reflected light wouldn't be polarized so little would be filtered.

As powerful as lasers may be, a (good) mirror should be enough to perform a "return to sender"...

Energy saving vs winter conditions. (1)

norttipertti (167435) | about 7 months ago | (#46226625)

So, new laser lights run with less energy consumption and cooler than traditional headlights. So either you waste energy on a heater that keeps lights clear of ice and snow or keep stopping often to scrape ice off the headlights.

I think I'll stay with the old technology.

Re:Energy saving vs winter conditions. (0)

Anonymous Coward | about 7 months ago | (#46226765)

The other 99.9% of the time, however, the energy savings are an advantage.

not a laser beam (0)

Anonymous Coward | about 7 months ago | (#46226643)

You are overplaying the "laser" angle. These headlights aren't emitting laser beams down the road. They emit light from the phosphorus, which is excited by illumination from a laser. If there was a more direct, more efficient way to make phosphorus emit white light using electricity, they would probably taken that other path.

Besides, the sun is not in Beta, but these headlights are. So fuck the headlights, fuck BMW, and above all, fuck Beta!

On a lighter note, in the part of the world where I was born and raised, we have a habit of referring to cars of a certain shape as "tiburones" (Spanish for sharks). And this model certainly fits the profile. So in a certain way, Dr. Evil will be delighted with the arrival of these cars. Now, if only they could be made amphibious so they can be driven into a swimming pool...

SuperDre (982372) | about 7 months ago | (#46226787)

Yeah, that's nice and all for the driver, but even with today's new headlights, it's a nightmare for oncoming traffic, headlights are so much brighter these days it blinds you as an oncoming driver.. And it's great if you can see for 600meters, but most people don't watch where they're going anyway..

Agreed!

How do we regulate these?

I'm sure these are ok for high beam situations.

They should not be used for daily driving.
If I get into an accident with one of these people it's their fault!

Also, have you guys noticed that the "safe cars" have no visibility? Their pillars are so freaking huge that you literally can't see cars on a collision course.

tleaf100 (2020038) | about 7 months ago | (#46226817)

so more stupidly over the top car lights for fat stupid drivers who apperently cannot drive safely/properly without 3kw of lights on their car.they should be forced to drive on 6volt 3 amp max lighting,either thst or give the fat idiots white sticks and remove their driveing licences. p.s what about traffic coming the other way,led and uv projectors are bad enough,but lasers are meant to be more powerful,so now you can be blinded from a mile away from by some fat git who cannot be arsed to dip lights and has over-ridden/turned off the sensors in the car that are meant to cut to dips when they detect an oncoming vehicle.

The output isn't laser (0)

Anonymous Coward | about 7 months ago | (#46226879)

For anyone not reading TFA: The output of the lamp comes from a phosphor spot that is excited with laser light from the back. The actual output is regular white light produced by the phosphor, so it's NOT A LASER! Let me repeat that for you: there's no laser coming out of the lamps!

The actual advantage of these lights are the lower energy usage, the smaller packaging and mounting and the quicker reponse time than incandescent bulbs. Combining these advantages, the automakers try to make "smart" headlights that are brighter than LED or xenon lights but don't blind other drivers as much.

There is no laser light comming out (3, Insightful)

Ivan Stepaniuk (1569563) | about 7 months ago | (#46226989)

Blue lasers positioned at the rear of the assembly fire onto a set of mirrors closer to the front. Those mirrors focus the laser energy into a lens filled with yellow phosphorus. The yellow phosphorus, when excited by the blue laser, emits an intense white light.

There is no coherent laser light coming out from the headlight.

This story was run a month or two back. It's only lasers for the highbeams, and only at high speeds. The regular headlights are normal.

Bright Headlights Blind Drivers, High Beam Only (0)

Anonymous Coward | about 7 months ago | (#46227081)

There are some super ridiculously bright and concentrated headlights and tail lights!

I'm sick of driving down the road, and having to cover my eyes because some Ftard in a fancy car has a blue lighted ultra bright light source that hurts.

Then The Acura in front of me brakes and I have to cover my eyes again.

These aren't cool.

There needs to be a maximum brightness per unit area for these lights on cars.

I'm thinking that it would be reasonable to get some sort of opaque tape and cover over all of the tail lights of these Ftards.
