DISCHARGE LAMP, ELECTRODE, AND METHOD OF MANUFACTURING AN ELECTRODE PORTION OF A DISCHARGE LAMP |
摘要 |
The invention relates to a discharge lamp comprising a sealed transparent bulb accommodating two electrodes, wherein at least one of said electrodes has at least a porous portion comprising first particles with a first mean particle site (mu1) defined by a first particle size distribution (11) and second particles (20) with a second mean particle size (mu2) defined by a second particle size distribution (21). The first mean particle size (mu1) is smaller than said second mean particle size (mu2). Consequently, an electrode portion with a higher porosity and a longer lifetime is obtained.
