Relate LED voltage drop to material direct bandgap[edit]

How does the voltage drop of an LED relate to the direct bandgap of the material ? (eg is it Slightly higher by the voltage drop of the rest of device which depends on the current ?) Could we also have a formula that relates the energy of the emission peak photons to the direct bandgap (is it just Ep=bg?) - and an explanation of why the emission curves have a FWHM of about 25nm ? - Rod57 (talk) 18:21, 29 October 2016 (UTC)

Dubious voltage drop figures not sourced - eg for UV[edit]

In the table in Light-emitting_diode#Colors_and_materials the voltage-drop figures (unsourced) seem unlikely. It might be clearer to have a voltage drop per material rather than per colour range. The UV range is too wide and could be split into UVA, UVB, UVC at least ? - Rod57 (talk) 13:53, 2 November 2016 (UTC)

lighthouse package[edit]

no info in article about uses/dis/advantages of this package shape design. — Preceding unsigned comment added by 92.19.42.51 (talk) 15:52, 23 November 2016 (UTC)

efficiency[edit]

Article states in the Technology section that temperature has been shown to make LED's actually more efficient (contrary to popular belief). It also states that they are used in freezers and that the low temps make them more efficient. I dont have the time to effectivly edit and fact check these things but maybe someone else does.

COB LEDs[edit]

Please would someone add information about COB LEDs ? How they are constructed ? Many thanks ! Darkman101 (talk) 22:36, 6 April 2017 (UTC)
