Discharge lamp having an electrode body with a hermetically sealed space that is partially filled with a heat conductor |
摘要 |
A discharge lamp with a high output power in which an increase of the current to be supplied to the discharge lamp can be enabled without the need to enlarge the discharge lamp and the surrounding system. The discharge lamp includes an arc tube having a pair of opposed electrodes, at least one of the electrodes having an electrode body in which a hermetically sealed interior space is formed, and a heat conductor partially filling the hermetically sealed interior space. This heat conductor consists of metal that has a higher thermal conductivity or a lower melting point than the metal comprising the electrode body. |
