Thank you LEDs

>>110338899People bitch about LED street lights being harsh on the eyes. That's the fucking point you digbat. They improve visibility and keep nighttime drivers awake. I don't want lights that are meant to illuminate driving areas to be "warm and cozy."
>>110338899 (checked)SOVL vs soulless.
You can have led lights and orange lantern glass.
>>110338976the only reason it's orange is because of the physical characteristics of the light. no one decided 'it should be orange' as an aesthetic choice.
LED street lights are fantastic for road safetyLED headlights are fucktarded and need to be banned
>>110338992I don't know man. My park has orange led lamps because it's better for animals.
Blackbody radiation is the only pure source of light.Jewish LED tricks are always going to be artificial and wrong. While people may use them to save energy they are never going to be the best.Case in point: the PWM cycle trick to modulate brightness.
>>110338996led headlights, trucks with train horns, rolling coal and loud mufflers are the ultimate antisocial personality filter. all of these mods should be legal to sell but anyone who actually modifies their cars with them should be thrown in a gulag. actual subhuman mongrels.
>>110338950Yeah brother I especially love that wonderful strobe action they do when the drivers start to fail a few months in because chinesium.
>>110338899as bad as led lamps are i can't help but roll my eyes every time i hear someone talk about how much they miss the orange sodium lights. it's such a strange virtue signal.>but it's le warmerand? they're also hideous. yeah they look cool from a distance like in op's pic but when they're shining directly on you they're oppressive. imagine a night club lit up with those things. you feel the warmth yet?
>>110339223^thisold = gud is suck a midwit take by boomers with nostalgia glasses on.
>>110338899This just gave me a thoughtWhat if the reason we can't see life on other planets is because their technology is so advanced all the light is 100% localised? Like the light is only where it needs to be, so there's no excess leaking into space?
>>110339298life on other planets could exist in a binary star system where there's no need for large amounts of artificial light we could also just exist in a convincing game of sorts with tons of hints and easter eggs suggesting this fact and the only "life on other planets" is literally stuff like candida or nanobots or something we can't quantify yet haha im just crazy though
>>110338899LEDs are the single worst invention in history. They don't even work, they produce anti-light that makes it harder to see than if they were not there in the first place. A while ago I nearly crushed a cyclist because the LED street lights made it harder to see. They are so worthless we would be better off getting rid of the street lights entirely.
>>110338950They are blinding yet illuminate nothing. There is zero visibility, only glare. Also, they destroy your night vision.
>>110338899Its funny how most of the engagement bait here is targeted at old people. lol
>>110338976native amber leds exist and have actually existed longer than "white" leds
>>110339537*white ledsit's funny how we can agree that warnings/notices should be amber because they're clearer to see in fog/snow/etc and don't hurt your eyes/wreck your night vision, but those are apparently bad qualities for street lighting
>>110339606I guess technically the blue LED is the real demon from which all that is bad flowed.
>>110338996>>110339140LED headlight are alright, a huge improvement even, but only if they were designed as such from scratch. LED retrofits for originally incadescent headlights are the cancer.
>>110338950LED lights only work if you absolutely blanket the area like a sports arena. No shadows. No spaces between lights. Total illumination. For that LED is objectively better.For the real world where you're driving on a road and there's hundreds of feet of between individual lights what LED's do is blind you every single time you're between the illumination peaks.
>>110338899nobody cares
>>110339606red being good to draw attention to signs doesn't make it good for general illumination
>>110338950People shouldn't be driving at night anyway, especially when tired which is as bad as being drunk. The light is just a placebo. You have significant night blindness in your central vision in low light and need to start looking at things with your near peripheral vision (15-20 degrees from center) which only has 10%-20% of the visual resolution of your central vision. At night most people would probably qualify as severely visually impaired or even legally blind, especially when moving at high speeds. In theory the higher blue levels should provide more vision to your peripheral vision, but in practice most of that is lost outside of a lab setting. It gets worse when you throw in LED headlamps, since getting blinded by that light will ruin whatever low-light vision your rod cells are providing and turn your legal blindness into actual blindness until they refresh a bit.>>110339223You're not lighting for street raves.
>>110339606Because the color of dim firelight is what humans have used for thousands of years.You have evolved to best function with the orange color of flickering flame and coals.Not noontime sun color that covers a small area. You are evolved to protect your eyes from that color and it dims your vision to avoid sunlight damage.Incandescent light being a glowing filiment of metal was actually closer to natural firelight.
>>110338899This guy is an idiot. Sodium Vapor is monochromatic which means you can filter it out easily when taking a photo.
>>110340350so are LEDs unless you go through extra efforts to make them less monochromatic
>>110340362An led is not monochromatic. Sodium vapor generates all light at a single frequency. An LED generates multiple frequencies of light to blend and create white. Colors which you probably want in your photo.
>>110340369>An LED generates multiple frequencies of light to blend and create white. Again, creating white LEDs, which is a more recent invention, is harder than creating monochromatic LEDs
>>110340362They are not though because tons of different color leds are used on homes in a city.But only a limited amount of sodium street lights used to be used before leds mad adding lights everywhere too affordable.Sky glow is way worse with leds because most home lights are unshielded pointing in all directions, and there is a lot more of them.Unless an area makes an ordinance and gives out tickets led skyglow is now far worse.
>>110340377But we are talking about street lamps and that is what street lamps use, white leds
>>110340383Which is not the fault of the underlying technology but how it was decided to be used.You could put monochromatic amber leds in street lights if you wanted to, no problem.
>>110338899This shit literally like having a web app on a 2 core 8 GB vm constantly 90 percenting the ram and imagining that the solution is to swap 1 gig
>>110340342>Incandescent light being a glowing filiment of metal was actually closer to natural firelight.it's not just closer, it's fundamentally the same thing. the only reason they tend to be whiter is because they're designed to run hotter. if you dim an incandescent bulb to the same temp as a campfire the light emitted will be identical, since they both emit light the same way (pure black body radiation)
>>110340395>hypothetical I am not talking what is possible I am talking about what exists now and what we have now is objectivity worse for astrophotographyDon't be so pedantic.
>>110340383>Monochromatic LED, but with coatingYour purple LEDs are still monochromatic.
>>110340395Would be nice.However street lights are less than half the problem now and used to be most of the problem before leds made generating massive light pollution inexpensive for residents.The OP picture is a cherry picked location probably with a law against regular home owner unshielded light that is actually enforced with fines.
>>110340412Shoe me the spectrum. Prove it to me it only emits light at a single frequency
>>110339140>>110339829>>110338996There is nothing wrong with well designed LED headlights. A well designed LED system will have a sharper cutoff than a halogen or a HID bulb in a reflector casing. A high quality LED retrofit will also have a sharper cutoff than a halogen or HID bulb. My retrofit LED headlights have a razor sharp cutoff. Modern LED headlights are so precise that they can keep the high beams on all the time and just shade the oncoming traffic. The problem comes from using bad retrofit bulbs where the cutoff doesn't work as designed. Aiming them at the sky so that the cutoff again doesn't work as intended. Or if the headlight design was dogshit from the factory. Which is the case more often than not. Especially VAG is to blame. A lot of their reflector designs are dogshit that should've never been approved for road use. And while they're the worst offender they aren't the only ones.
Here is a low pressure sodium vapor. This is what monochromatic light looks like
>>110338899>soul vs. soullessI knew led-lights were shittier!
>>110338950Yeah I love them messing with the circadian rhythm of animals, insects and humans. Lovely.There are better ways of keeping drivers awake without poisoning people with shitty-quality led's (which are the cheapest, thus the ones used exclusively).
