How is this not a LED?

This indicates the transistor had 1 input and 2 outputs: 1 electrical input, 1 electrical output, and one light output. I’m no electrical engineer, but that’s how I’d describe a LED’s inputs and outputs if asked. I’d also describe a typical transistor as having 2 inputs and one output…

In what way is this thing not simply a LED with a misleading name?
In what way is this similar to a transistor? With only one input it sounds like it cannot function as a switch, which is the entire point of a transistor.

I’m not criticizing the device. Just saying, taken at face value, this sounds to me like a work of fiction. 174.51.68.20 (talk) 18:26, 25 January 2022 (UTC)[reply]

The second reference gives some information. It's a transistor because it has two junctions and three terminals. Changes in base-emitter current give rise to greater changes in collector current, hence it has gain. The base-emitter current produces photons instead of just heat, as in a conventional bipolar transistor. So it's a LET, not a LED. 87.75.117.183 (talk) 18:10, 29 January 2022 (UTC)[reply]
