Research Abstract |
The correlation of emitter loss and electrode temperature distribution of the fluorescent lamp was elucidatedexperimentally. An electrode design to optimize the electrode temperature was shown to be a key issue, while luminous efficiency can be improved by Kr addition into working gas. It was also shown that the enough thermionic electron emission and the suppression of emitter loss can be achieved by controlling the amplitude and phase of an additional heating current. Furthermore, ητ was proposed as the useful design index of the highly efficient and long-lived fluorescent lamp
