Also known as "incandescent lightbulb"

Also, heating elements. Which I guess are just durable incandescent lightbulbs.

The viewing angles on these new LER displays are going to be insane

Every diode is an LED if used wrong enough.

Everything is a light emitting resistor if you send enough power through it.

The sun: Damn it, I knew it 😠. I thought I was special 🥺.

In university in the first lecture I visited they demonstrated that fact using a pickle. They sent current through and it glowed.

My stovetop is a light emitting resistor. And compared to LEDs, it is multifrequency! Checkmate atheists.

Same resistance, variable voltage.

Gas emitting capacitor

Smoke producing transistor

If you stop to think about , all resistors are emitting light, but under certain conditions it becomes visible (to our eyes)

[–] [email protected] 10 points 10 months ago

It’s the other way around. LEDs are usually monochrome.

Quartz heating elements are also resistors that emit light, but i've never seen anyone complain about them, people tend complain when they dont actually

Emitting is spelled wrong. In the age of fucking spell check software being literally fucking everywhere, there is no excuse other than to chalk it to simple stupidity now.

Edit: I am stupid.

Meeh, we all make mistakes buddy ☺️.
