A 100 lm/W efficacy low-pressure Xe discharge tube
The luminous efficacy of a Zn2SiO4:Mn-coated, low-pressure Xe-positive-column fluorescent tube is found to be as high as 100 l/W which corresponds to an electric to 147-nm radiation energy conversion factor of 66%. This high efficacy can be attained under conditions (pressure)×(column diameter)≃1 To...

| Zusammenfassung: | The luminous efficacy of a Zn2SiO4:Mn-coated, low-pressure Xe-positive-column fluorescent tube is found to be as high as 100 l/W which corresponds to an electric to 147-nm radiation energy conversion factor of 66%. This high efficacy can be attained under conditions (pressure)×(column diameter)≃1 Torr cm and (current density)?3 mA/cm2. |
