Through-hole LED package identification

Question

I am looking for a way to search for a replacement LED. Unfortunately I don't know the name of the package.

The LED has a kind of conical recess at its tip to diffuse the light sideways instead of axially.

I am missing the technical name for that specific tip. Therefore I have difficulties to search the manufacturer's websites for that specificity.

What is the official name of that kind of tip?

Answer 1

I think it is called a "dimple lens" LED but I'm not certain.

For a quick and dirty replacement you could take a flat top LED (or flatten a round one with sandpaper) and drill the dimple in it using a drill bit of larger diameter than the LED...
