In the automotive subforum we have a thread discussing advancements in laser boosted and LEP based vehicle lighting. I haven't paid much attention to the LEP space, so this discussion actually got me looking at what LEP based vehicle/offroad lighting is available. Both baja designs and rigid industries appear to be using this kyocera LEP emitter. I'm curious if anyone here in this subforum knows of an LEP light using one of these particular chips, or if anyone has experimented with any available LEP emitters for modding lights.
 
Digikey apparently has a very small quantity in stock. Tempting. But not in the cards at the moment

This seems like a weird application.

Outside of the "this throws super far" marketing pitch, I cannot fathom an LEP being practical for automotive use. I'd really be interesting to see how people are using this in a helpful way. I'm just imaging the usual horribly misaimed fog lights blasting all oncoming traffic in the face, causing vehicles to just swerve straight into the LEP vehicle, haha.

I actually had previously watched the video on the linked Mouser page, and they had probably the best single practical use I'd ever seen for an LEP: using them to guide cargo ships at the dock, haha. Of all the things they try selling in that video, the shaped beams on a dock is kind of AMAZING.
 
The integrated laser boost in the bmw headlamps is neat. It appears it's controlled seperately from the highbeam function to both prevent it from being used when flashing the high beams for traffic signaling, and below a speed threshold, even if the highbeams are activated. It makes sense to have an integrated driving light for a vehicle that may see high speeds at night.

Personally, I'm always a fan of adding driving lights to my vehicles. The biggest issues with cars is that, generally speaking, larger lamps are better. I currently have a set of diode dynamics SS5 Sports on my truck. My other vehicle is an 8th gen honda civic, where mounting a suitable driving lamp was a challenge, and simply upgrading headlamp bulbs was a non-starter, the lamps themselves have poor beam width for lowbeam, and the highbeam floods the foreground with excessive light, while not providing much reach. Before that I had a 3rd gen 4runner, which I had mounted a set of cibie LED super oscars on the winch bumper, as I had a ton of real estate to work with.

LEP makes sense for a high performance lamp in an extremely small, and thus easier to mount, form factor. Sae J581 (aux. Driving lamp standard) limits driving lamps to 75kcd intensity for each lamp, but an LEP could achieve this 1- without being maximally driven, meaning the housing can be smaller with less need for cooling fins, and 2- the optic it is paired with can be compact in size.

I have a friend with a '23 bmw 440. He does not like the highbeams, but he also doesn't want to try to mount even a small set of lamps externally, like a pair of DD SS2's. But an LEP based light could be compact enough, and offer enough beam control, to be mounted extremely low (e.g. in place of oem fogs) and not risk flooding the foreground with excessive spill, while still functioning well as a driving light.

I mean, I understand what an LEP is, and how far it throws, BUT they also only throw in a VERY small, limited area, thus the uselessness. For headlamps, I don't know if I'd describe a 6-12" circle of light half a mile in front of me as "helpful."

That's why I said I've yet to see any usage that was truly practical.


For these lights you're talking about, are you talking about using these on the roads?
While I'm sure this makes YOUR life easier, do you not have concerns about blinding oncoming traffic?

While I'm sure you'll insist you only properly install your aftermarket lights, I've yet to ever see a single person "upgrade" their driving lights and not make it a nightmare for everyone in oncoming traffic. There's an actual tool to calibrate headlights, but it's VERY expensive, so when you do see them, it's MAYBE at a dealership...i.e. NO ONE calibrates their lights properly.

I'd trust BMW to integrate a neat feature with an LEP, as Germany has strict laws about headlights that keep them from blinding oncoming traffic. America does not, and the "F*** you, this is better for ME" attitude seems to run a bit too deep for our own good.

I pretty much never drive at night anymore because of idiots and aftermarket lights...and I'm still relatively young. It's absolutely insufferable these days. I'd sure hope you're not contributing to this problem, as it's EXTREMELY dangerous. I've had many harrowing experiences of completely losing the ability to see while at speed because I was blinded. Again, being not too old, and having healthy eyes, I'd say my temporary blindness recovers faster than average, but it's an absolutely awful thing to experience.

I'm even careful with the lights on my BICYCLE (I only use ones with a cutoff), cause I've seen blinded riders careen into the "LOOK AT MY 2,000 LUMEN LIGHT" cool guys, haha.

Why anyone wants to risk that while driving 60+ mph, I'll never understand...
 
I would prefer getting blinded by traditional headlights, or newer LED headlights. LEP? That "L" stands for laser. Would prefer not getting blinded by those! Have already had eye-surgery on each eye, a few years apart. I'd get down on my hands and knees and kiss the bare feet of Dr. Juan Romero for having saved my eye-sight both times if that's what he wanted!

Actually, the cool part of LEPs is the phosphorus renders the laser light 100% eye safe (save for the brightness, haha).

That being said, the 76k candela limit on headlights in the US is our attempt to keep headlights from blinding drivers.

I feel like another decade of this insanity, and we're going to end up with serious regulations about headlights.

I miss the cozy days of my youth, where I'd just put on some good music, and a night drive was just so pleasant. Sure, once in a blue moon, someone would leave their brights on, but a quick flash and they'd turn them off, and all was well.
 
@Monocrom

The kyocera modul uses two laser diodes to energize a remote phosphor. There is no emitted laser light. It's simply a very small, very high intensity lightsource.

We already have serious regulations on... headlights and everything else. Enforcement is poor, universally.

The tried and true solution has always been more regulation. Which is why we have so many overlapping/countermanding regulations, rules, by-laws, codes, and laws on the books.

The older I have gotten, the less I care about the letter of the law/code/regulation. If I have a question about something, and especially if I find there is more than one regulation/law, and often times they are both still on the books, but at cross purposes, I try to understand the purpose behind it.

For driving lights on my vehicles, I largelt don't care about maximum intensity violations. In theory they're useful, and justifiable. But I do a lot of night driving. I've driven all across the lower 48 in all sorts of weather conditions. More is more often than not, better than less when it comes to light when it's directed appropriately.

Most people don't care and just use whatever, wherever, wired up however, and get by. Maybe they get a ticket every once in a while, odds are they don't.

I'm interested in how this particular advancement in lighting techbology is being implement by both the OEM and aftermarket. Given the specific use case I've cited, maybe if the performance to size ratio is sufficient, then something will come to market, or some oddball diy-er will bust out a few custom lamps on his mill. Highly unlikely given the expense.

I Just Think It's Neat^TM

Well, but that's my point... NO ONE directs this stuff correctly, save for when it's leaving the factory.

And no offense, but your response typified the exact, "F*** you, this is better for ME" attitude that makes so many things a nightmare in the U.S. It seems so short-sighted (pun intended) to blind oncoming traffic so YOU can see more... Head-on collisions are insanely dangerous. If you're an older driver, I would have thought you'd be MORE sensitive to how terrible bright lights are for old eyes...

I get that LEPs are neat, but I cannot fathom anything good coming from Americans installing them on their vehicles and using them on the roads. It's just going to further increase insurance rates as more collisions are caused by blinded drivers.


Luckily, it's perfectly legal to affix retroflective tape to the back of headrests and sun visors, hahahahahahaha.
At least that way, we can both be blinded by your lights, now!
THAT is some cool technology!
 
Lol, you think headlamps are correctly aimed when leaving the factory.

You're awfully presumptive about how everyone else drives and operates things. Glad I don't know you irl

The most modern lights do leave the factory calibrated.

Outside of that, NO ONE gets them calibrated, because the machines to do so are very expensive, and it's a service few are willing to pay for, so shops rarely purchase the machines (DEALERS rarely have them), because there is such a low return on the investment.

I'm presuming nothing. I drive around, and am familiar with cars, car repair, and the automotive industry. It's not a secret that headlights have been becoming a bigger and bigger issue, and it's no secret that the vast majority of people who install aftermarket lights are NOT paying to have said lights professionally calibrated.

You and I know you're not doing it, either. So, why pretend?

I'm sorry that makes you feel personally attacked in some way. That was not my intention. We're all adults here, and so I assumed you would be able to handle a polite truth, albeit a not-so-flattering one; using high intensity lights (ESPECIALLY aftermarket ones) creates a very real and serious hazard on the roads.

If hearing that hurts your feelings, I think it has less to do with me, and more to do with the fact you likely realize I'm correct, but may not want to acknowledge it.

I wish I DID know you in real life, so I could politely remind you of your obligations as a driver on the road to work with everyone else to make sure we're all a bit safer. Driving motor vehicles is a privilege, not a right, and everyone cooperating means we all can enjoy the experience more, and will have less government interference in the whole process.

Didn't you ever read Spider-man comics? With great power comes great responsibility, haha.
 
Disregard my previous welcome. Virgil would have pruned this topic to the 4 or 5 relevant posts by this point.
