120 lumens a watt coming through

You don't invent leds, it's more of a discovery

>120 lpw
Are we in 2012?

cree.com/led-components/media/documents/ds-XHP702.pdf
pct.cree.com/dt/index.html

An N2 binned XHP70.2 will do 120 lpw even at 20 watt.
A P2 binned 70.2 will do 120+ lpw at 28.4 watt.
That's without driver losses though (6-12% typically)
Higher binned ones can reach 170 lpw easy when driven under 5 watt.

Cree isn't that high on the list anymore.
200 lpw+ is quite trivial

True.

Every diode emits light.

Already a year old

tfw efficiency gains are almost over.

>The new XP-G3 LED doubles the maximum light output of similar size competing LEDs and delivers breakthrough wall-plug efficiency of up to 81 percent
Don't know at what amperage it is 81% efficient but it emits 3.4W of blue light at 2A (6W) which is still clearly way over 50% efficient.

>Higher binned ones can reach 170 lpw easy when driven under 5 watt.

>You can put 180 watts through xhp 70
False you fucking retard, an xhp 70 has a max output of about 32W.
180 watt would fry it really quickly, unless your information is somehow more correct than Crees literal datasheet.
Many Citiled COBs can handle 180 watt quite easily, but Cree doesn't have such high power COBs unless the 3590 is no longer their most powerful

Yeah just google xhp 70 180 watts
Ez pz retard

I love LEDs too but it is a shame that when it comes to bulb replacements, normies STILL don't care about color accuracy so LEDbulbs with high CRI are still expensive and relatively rare.
It's fucking annoying when you buy a bulb and everything looks like tinted in piss yellow instead of having the "normal" warmer yellow'ish color temperature of a normal bulb, with all colors looking as they're supposed to look. Warm white/neutral white/daylight white, all irrelevant if the CRI is low as fuck.

Have fun frying the chip if you think you can think it will handle that wattage continuously.
And have fun buying a heatsink + cooler numerous times as expensive as the chip itself.

A CLU058-3618 will handle 500 watts continuously, probably a lot more in short bursts like the XHP70 but again you will risk frying it if you keep it up for more than a few seconds.

If you want real power

Youre angry but i dont get why.

Also you can't fit your faggot led in pic rel can you?

Maybe it's time to stop posting until you're 18.

Maybe it's time to stop taking yourself so seriously

Especially here of all places.

Hope you feel better

wtf

The photoelectric effect is a discovery (thanks Mr Einstein!), the the use of such in a mass producible device is an invention.

>high CRI are still expensive

Because they are harder to make, not because of "normies".

>and relatively rare.

So?
Everything can be found on the internet.

I prefer lasers but leds are fine too I suppose.

FANCY.
Will play with soon.

Shipping is pretty expensive but you can combine them with pcb shipping from jlcpcb

That does look mighty sharp/bright.

alpha af

that is mainly just the picture, you can also pretty easily turn down the brightness of led's so it shouldn't be a problem

no you piece of shit, mosfets are the best shit.

analog displays are best electronics porn

>literally a transistor in a loop that self-blocks and self-unblocks itself so fast that it happens on frequencies of a visible spectrum, so the whole thong becomes an antenna that that transmits radio waves of light
Fucking magical.

i dont think thats how it works

Attached: 1521638261704.png (251x251, 71K)

This isn't how it works.

do you even know the difference between electronics device and electrical device?

That's what they want you to think. It all happens in the material itself, and there is a lot of short-circuted transistors on the p-n junction.

Problem?

analog displays are not electronics.

i seriously hope you guys dont believe this

nah, the microfiber towel is probably the greatest invention since air conditioning

i like led strips, can't get enough of those individually addressable led strips

for some reason everytime I think about touching microfiber towels my teeth hurts :S it feels horrible

>can't get enough of those individually
as your mom can't get enought of my peepeer ;)

They were discovered a long fucking time ago

it was originally discovered by mexicans.

bought 50 of these, needed to test them all. 3 were bad. seller sent 10 more. those were ok.

Get cancer /v/ermin

Even the shittiest LED bulbs are 80-90+ CRI. You have to try to find awful ones.

>Stop working with electronics
>Buy overpriced keyboards and post about headphones and watches
Pathetic. You can't buy a brain.

lol, what basedboys thinks is work with electronics these days, uploading script based instructions into a SoC to turn on a LED.

>The entire computer is made of sandwich LEDs.

Paper shredders use IR LED to determine if paper is inserted to run the shredder.

If there's no IR signal being emitted can I just desolder the IR led and solder a new one?

As long as the new LED emits a wavelength the sensor will detect, absolutely

Anyway outside of schematics to determine wavelength? Schematics not available.

Look up part number of light sensor, should be able to find a spec sheet

The development of cheaper ways to produce blue light using diodes really changed the way the world looked. It unlocked the whole RGB spectrum with cheap, easy to build diodes.
Without it we wouldn't have efficient lightbulbs, small and portable displays or affordable screen monitors.
Sadly blue LEDs indirectly killed the cyberpunk dream of foggy, neon light infused streets, they also killed comfy CRTs.
Cheap to manufacture blue LEDs are as influential as the invention of the internet imo.

But not all light emits diodes.

the blue led has only been feasable for ~20 years
