Abstract (en)
A ceramic discharge lamp (20) includes first and second electrodes (24, 26) that are disposed in non-axial relation. In a preferred arrangement, the electrodes extend inwardly from one end of the lamp to define a single ended ceramic discharge lamp. The electrodes are disposed in parallel to provide for precise control of the arc gap in one exemplary embodiment while the electrodes are angled in non-parallel relation in another preferred embodiment to limit the potential for arcing outside of the chamber. The legs (62, 64) are integrally formed in one body component (60) and an integral lens is provided in the other body component to increase the lumens distribution since there is no leg to interfere with radiation from the chamber. <IMAGE>
