Anyone who wants to try to magnify a source of light so that it is smaller than the source (without losing any light) with any combination of mirrors or lenses can use this simulator: phydemo.app/ray-optics/simulator/. But here is a reminder. All real sources of light emit light in at least 180 degrees. So in the simulator, you can't use a source that artificially emits in less than 180 degrees (you have to use point sources of light, you can line them up in a row to make a source that isn’t only one point). I made one setup with one LED bit.ly/3SawbxB and one with two LEDs bit.ly/3zQcjJJ. You can use the "detector" to see if you can get more light in one area than at the surface of either LED. Good luck!
But you can't make a point smaller than a point, it's already a point. The whole... point of the exercise is to make a non-zero sized light source focused to a smaller size.
Because the heat of any real light source is going to be dispersed over the source's area, it is possible (and in fact, trivial) to make a small focal area hotter than any single point on the source. You have less TOTAL heat energy, but can reach a higher temperature.
The best you can do to approximate this in your simulation is to use multiple point light sources arranged on the surface of an object. Then your goal is to concentrate the beams from those multiple sources into a single spot with more beams than any 1 of those points can produce.
Line a bunch of point sources up in a row as the source.
How about a parabolic mirror?
Arthur Eddington was the man.!
I'd of like to have met him.
The light source is not continuous - it is an array of point sources. As such, one can redirect the light from these sources (the LED emitters) individually onto a single point. There will be lost energy for sure so we are not breaking the laws of thermodynamics. That single point will have a very high temperature due to the energy from multiple emitters overlapping at a single emitter sized point.
Can you create a fixture that allows for enough small lenses to be arranged in a way to make this into reality? It would be easy to do with a CNC capable of cutting and polishing glass. But to do it by hand would require multiple individual lenses and some sort of mounting structure. Perhaps a 3D printed structure and off-the-shelf lenses?

here's the thing.. that flash light wasn't one big light source but lots of tiny light sources.

There was an opportunity to have someone in the town when the flashlight was aimed at the town, and have that person record if they saw the flashlight.
That is an insane light. The amount of particulates in the air is stunning to see. I have experienced this with underwater fishing cameras. Most of these cameras have lights and IR lights that shine straight ahead. The reflecting and flaring off of particulate matter in the water column renders these cameras almost useless. The video looks like a snow storm or blizzard. However, I rigged mine up with a waterproof light that sits well above the camera and shoots down at a slight angle, preventing flare and you can see perfectly. It would likely stun us to know how many micro-grams of particles we breath in daily.

If you wanted to capture all the light and then focus it to a point, you would need a much more advanced mirror array to take all the light and reflect it inward to a point/collector. An example of this in the real world would be a solar power tower. So basically infront of the flashlight would be a bunch of mirrors all angled correctly to take that light and focus it to a point. Once that is achieved you could then attempt to use a magnifying glass to further condense the light to an even a smaller point. In the case of a solar power tower, the mirrors on the ground reflect the sun light in an area to point directly at the top of the tower in the middle of the array which heats water in a tank to create steam to run a turbine creating electricity. Same princable here just at a much smaller scale. Great video!

I'm not sure you can assume sun-like temperatures for a source based on wavelength similarity. The rate of radiative heat transfer is based on the temperature of the source and the sink. I'd guess that the maximal temperature is either a) the junction temperature of the LED (~350K, too cold, paper ignites ~ 500 K) or b) an effective temperature based on the light output (math below).
The energy of each photon emitted by the LED: E=hc/λ
where h is Planck's constant (6.626×10−34), c is the speed of light (3E8 m/s), and λ is the primary wavelength of the emitted light. For an example λ=500 nm, E=3.976E-19 J. The effective source temperature could be estimated by equating the power of the emitted light to the radiative power of a black body at the source temperature, T_source. Using the Stefan-Boltzmann law for power radiated by a black body:
P_light=σA(T_source^4−T_a^4)
With an example power of the emitted light (P_light): 0.3 W, ambient temperature (T_a): 300 K, surface area of LED (A): 1E-4 m^2, and solving for T_source:
T_source^4=(P_light/σA)+T_a^4
Substituting the example values, T_source ≈ 783.7K
If true, it's no surprise that the LEDs can back-drive enough heat to melt themselves, since the effective temperature is 300-400 K above the junction temperature. You could measure the total energy flux by measuring how quickly the beam can heat a matte black target from Temp 1 to Temp 2 and estimate the source temperatures from that.
The smartest goose of all geese. 👍🏻
He is mixing up the color temperature of light and the thermal temperature of material objects. For instance, a heat lamp is 6000kelvin. To achieve the same amount of ouch ouch hot hot heat from the latter would require driving the source with tremendously more power than the former. Hopefully he understands this throws a hitch in his explanation of things. 6:13 6:21 7:04 7:36 Also RIP flashlight, but she didn't get anywhere near 5,726.85c or 10,340.33f LOL
Personally night hiking with my dogs in the Oregon woods became one of my favorite hobbies once I bought a powerful 18v Ryobi One+ flashlight with multiple rechargeable batteries. It's so bright, shines so far & has great battery life. That it makes hiking at night so fun! I can light up things multiple football fields away so the more i got used to exploring in the woods at night the more i learned that I can scan my surroundings as I walk and most of the time I can see if there's any critters around me due to how reflective their eye's are from my flashlight. This gives me a better understanding of my surroundings. Obviously it's not perfect so I also carry a airhorn on the side of my backpack, a telescopic baton in my pocket and a few helpful things in my backpack just in case. You never know so it's better to just have things with you and not have to use them compared to something unexpected happening and not having something on you. Regardless once you start getting more used to exploring the woods at night it actually becomes such a uniquely wonderful experience. You learn to become more in tune with your senses and your sense of direction and your overall perception as a whole.

0:50 Looks familiar... Isn't it the same parking lot where Veritassium tested night vision goggles? He is lucky to miss your test.
The issue with you bringing up the conservation of Etendue in this context is that you're treating "the flashlight" as "the source" of light. There are 32 LEDs which are individual light sources. The way to magnify this would be to take the lens off the end and create an array of optics to redirect each LED inward toward a predetermined focal distance. You could get an area the size of one LED to have 32 times the the energy of just putting something on the flashlight. More, actually, since the area between the LEDs counts as area on which the energy is being spread across.
Yes, the concept was being applied in a simplistic manner.
Yeah, I thought that too. Like how we combine multiple laser beams to make a powerful cutting tool. It won’t increase the maximum temperature, but it’ll sure increase the energy density you can put into that focus!
The focal point can't get hotter than the light sources, because if it could, it would be heating up the light sources... because the lenses are symmetric.
One might as well take this deeper: why would the light emitting diode, an entire semiconductor device, be "the source" of light? A photon is emitted when an electron falls into a "hole" in the electron shell of just one atom in the p-type semiconductor material.
What if the creation of this company and their goal of creating the world’s brightest flashlight is a result of the original company owner’s unimaginable fear of horror game scenarios

The LEDs would burn like at 7:44
What you really need to do is put a separate lens on each LED and focus each of them on the same point. That way, you can get a point as small as a single LED, but with the energy of all of them combined.
you would lose some energy into the mirrors

Does it really affect them
not to suggest that this technique would break the etendue thing, but in terms of achieving the hottest point from a light source I would think that if you arrange the source -> collimating lens -> focusing lens -> target, would get the most energy of the source onto the smallest point.
Holy 🐄
Not an expert or anything, but I think this runs into the exact same issue. "Collimating lens" is doing a lot of lifting in this and ultimately while it could theoretically perfectly collimate light from a point source, my guess is it would be imperfect on any other point of the light source (i.e. you'd lose some of the light from imperfectly collimating the other LEDs or even other points on the same LED). Then when focusing this on the other end you'd receive this imperfect collimation at the focusing lens and the same issues addressed in the video arise. This setup might be able to reduce how quickly the energy falloff happens as you move further away, but inevitably thermodynamics arrives to spoil the fun.
Trust me, you can't... I worked on particle accelerators, x-ray lasers and designed synchrotron beamlines costing multiple million euros: you can't focus such a big amount of leds putting out light in all directions on a spot as small as the source itself.
It's different with lasers - I worked with later beams about 30 cm diameter that could be focused on a few micrometer target, but that's because it's a laser where all photons have very parallel rays, but even then, a lot of the electrical energy of to make such lasers work won't arrive on the target. And these were multi-terrawatt lasers that create plama's hotter than the sun.
@@SwissPGO "leds putting out light in all directions" - that's the thing, it isn't in all directions: they've already been aligned (collimated) at the LEDs themselves. You can even see it in this video - that the focused circle getting burnt is smaller than the circle of the source - I think all those LEDs shining in the same direction are acting a bit like a smaller circle further away. As a thought experiment to show what I'm talking about: you could give each individual LED its own set of lenses to focus its light on a spot the size of a single LED and it would not violate Conservation of Etendue.
Led light is non-coherent, at the production, it is électroluminescence and the light is emitted into all directions: each photon emitted has no clue where the other photons went, an will be reflected and guided by a lens into a main direction, but the light will spread out quickly in a divergent non-coherent beam that is inefficient to focus.
A laser is a whole different process of light emission: everything aligns, which makes focusing possible up to the diffraction limit very efficient.
It may be that the flashlight in question uses diode lasers (yes, that's also a thing)... but a laser is monochromatic, and to obtain white light, a fluorescence step is typically used which breaks the coherence and increases the divergence, so you end up with the same situation.
And... even if each led would be able to produce a perfectly coherent beam, aligning all of them is very difficult, especially since the temperature of the device is not stable.
Part of my phd research involved the aligning of multiple laser beams on a target, and this happened using lower powered helper beams and constant measuring and correction to adapt to temperature variations. You can't have that in a flashlight because nobody is willing to pay a million for a flashlight that has the size of a tank.

He has white skin so it will reflect more light than the darker objects he put in front of it. I can light paper on fire with my flashlights but I don’t think any of my lights will set fire to white computer paper even when I set the paper all the way against the lens, maybe if I left it for a longer time but I don’t want to burn up my leds either. Also if I put my skin (also white) all the way up to the lens I can easily burn myself but it’s safe a few inches away for a short time.

With the brass nozzle in his fists, with this great python spitting its venomous kerosene upon the world, the blood pounded in his head, and his hands were the hands of some amazing conductor playing all the symphonies of blazing and burning to bring down the tatters and charcoal ruins of history. With his symbolic helmet numbered 451 on his stolid head, and his eyes all orange flame with the thought of what came next, he flicked the igniter and the house jumped up in a gorging fire that burned the evening sky red and yellow and black. He strode in a swarm of fireflies. He wanted above all, like the old joke, to shove a marshmallow on a stick in the furnace, while the flapping pigeon-winged books died on the porch and lawn of the house. While the books went up in sparkling whirls and blew away on a wind turned dark with burning."
