Your answer here is good (worth my upvote), and the diagram specifics aren't important to it, but I get twitchy when I see a "pretty" diagram that's got clear factual errors. I get twitchier when I see the diagram propagating. | |

| Feb 27, 2020 at 17:16 | comment | added | jeffB | That diagram is inaccurate. First, different LEDs of the same color can have different characteristic curves; a graph like this presents only generalities. Second, the overall trend should be toward higher voltage for shorter wavelengths, since shorter-wavelength photons contain more energy; the green and yellow curves, for example, appear reversed. Third, a "white LED" is generally a blue LED embedded in a yellow phosphor, and so it will have the same characteristic curve as a plain blue LED. | |
