摘要:
A high pressure discharge lamp of the present invention is provided with a light-emitting bulb comprising a light-emitting part and sealing sections; metal foils embedded within the sealing sections; and a pair of electrodes having one end protruding into the light-emitting part and having the other end embedded in the corresponding sealing section and joined to the corresponding metal foil. An embedded length L (mm) of the electrodes that is defined by the length between a light-emitting part side end of the metal foil and the border section between the protruding section and the embedded section of the electrode, and the temperature T (° C.) at the joint region of the electrode and the metal foil are set to satisfy 1.8≦L≦2.8 and T≦970.
