temperature is not a solid thing to define on the molecular level...as
such is doesnt even exist. the molcules in the tube are electrically
excited to the same level as the gases on the suns surface. vibrationally
they dont sit on any surface long enough to make any real xfer of energy.
instead they release their energy by release of electron(s). when 'less
excited' they recoup their lost electrons in their own time. said
electrons release then excite the phosphour coating at lower excite level
- which then releases energy in the form of the white light you get from
the tube + a little thermal energy (tubes do get warm after some time)
i guess theres plenty of online resources for this kind of thing...a
monitor works in a more direct manner..electon beam goes straight to the
phosphor...it'd be impossible to have random gas electons inside a TV
tube.
on a random thought process....if there were a very small-diameter mirror
tubing inside a phosphour tube, then light release which goes INTO the
tube could be reflected out directionally....such things probably exist.
no, I dont know how those low-energy tubes work yet
Amiga-related lighting note: We going to have neon tubing for the AmigaOne
as an addon option? Or even some UV lighting? :-)
