Process by which the
resonance radiation emitted in a
lamp is absorbed and re-emitted many
times in the plasma prior to striking the phosphor.
This process is called radiation
trapping or imprisonment.
Note:
Radiation
trapping lengthens the effective
lifetime of emission as viewed from outside the
lamp.
The control of this
trapping is, therefore, an important design consideration for low-pressure lamps.
