A double-capped short arc flash lamp includes an arc tube, a pair of main electrodes disposed in the arc tube, and a pair of auxiliary electrodes disposed in the arc tube. The flash lamp also includes inner leads and outer leads associated with the two auxiliary electrodes, respectively. The flash lamp also includes a first sealing tube and a second sealing tube provided at opposite ends of the arc tube. A sealing glass tube is partly received in the second sealing tube. Grooves are formed in the outer surface of the sealing glass tube in a region where the sealing glass tube overlaps the second sealing tube. The grooves extend in the axial direction of the sealing glass tube, and are configured to receive the inner leads and the outer leads. Metallic foils electrically connect the inner leads with the outer leads, respectively. |

1. A double-capped short arc flash lamp comprising:
an arc tube made of glass, and having a first end and a second end opposite the first end; a pair of first and second main electrodes disposed in the arc tube; a pair of first and second auxiliary electrodes disposed in the arc tube, the pair of auxiliary electrodes being used to trigger discharge; a first inner lead and a first outer lead associated with the first auxiliary electrode; a second inner lead and a second outer lead associated with the second auxiliary electrode; a first sealing tube provided at the first end of the arc tube; a second sealing tube provided at the second end of the arc tube; a first core wire extending from the first main electrode in the first sealing tube, and protruding out of the first sealing tube, the first core wire being sealed to the first sealing tube; a sealing glass tube partly received in the second sealing tube, the sealing glass tube being fused and joined to the second sealing tube, the sealing glass tube having an outer surface and an axial direction; a second core wire extending from the second main electrode in the sealing glass tube, and protruding out of the sealing glass tube, the second core wire being sealed to the sealing glass tube; a first groove formed in the outer surface of the sealing glass tube in a region where the sealing glass tube overlaps the second sealing tube, the first groove extending in the axial direction of the sealing glass tube, the first groove being configured to receive the first inner lead and the first outer lead; a second groove formed in the outer surface of the sealing glass tube in the region where the sealing glass tube overlaps the second sealing tube, the second groove extending in the axial direction of the sealing glass tube, the second groove being configured to receive the second inner lead and the second outer lead, the second groove being formed at a different location than the first groove; a first metallic foil configured to electrically connect the first inner lead with the first outer lead; and a second metallic foil configured to electrically connect the second inner lead with the second outer lead. |
