摘要： A long-life high-pressure discharge lamp can (i) suppress damage to sealing portions, especially at an initial stage of the accumulated lighting time, (ii) allow for easy assembly of components such as electrodes and (iii) prevent deformation/ripping of metallic foils. An arc tube is a glass enveloping vessel with electrodes arranged therein, and includes: a light emitting portion in which materials are enclosed and a discharge space is formed; and sealing portions provided at ends of the light emitting portion. Each electrode includes an electrode bar whose first end is in the discharge space, and whose second end is in the corresponding sealing portion and connected to a metallic foil. The second end of each electrode bar is partially wrapped around by a sleeve-like metallic cover foil that has a cut-out section positioned over a joining area where the second end of each electrode bar is joined to the metallic foil.

摘要： The present invention is directed to a method for manufacturing a high-pressure discharge lamp including: a spherical portion forming a light-emitting portion (1a); sealing portions that are connected with both ends of the spherical portion; an electrode (2a) that is sealed to each of the sealing portions; and a metal foil (3a) that is connected with a rear end of each electrode. A vessel provided with a cylindrical glass tube (8) on both ends of the spherical portion is used, a connection structure of the metal foil and the electrode are disposed in the glass tube such that a front end of the electrode is positioned in the spherical portion, and the glass tube is melted by heat and shrunk for sealing the metal foil and the electrode so as to form the sealing portion. An inner diameter φ of the glass tube before the heat-melt processing and a distance L from an edge of the metal foil to the internal space of the spherical portion are set to satisfy a relationship of L/φ≧1.35, a corner of an edge portion of the metal foil on a side of the connection with the electrode is cut so as to form a wedge shape (7a), and subsequently the sealing step is performed. Thereby, it can suppress the generation of the breakage during the lighting life span, which is caused by a gap generated from the metal foil to an axis of the electrode during the sealing processing of the high-pressure discharge lamp having a high brightness property.

摘要： An image display device accurately evaluates the possibility of problems occurring due to the state of impure gas inside a discharge envelope in a high pressure discharge lamp. The image display device includes the high voltage discharge lamp and an evaluation unit (51) for evaluating the possibility of problems occurring due to the state of impure gas. The evaluation unit (51) includes a high voltage pulse generator (57) that generates a high voltage pulse for breaking insulation in the high pressure lamp, a constant current generator (58) that generates a constant current for illuminating the high pressure discharge lamp in a glow discharge state, a lamp voltage measurer (59) that measures lamp voltage during illumination in the glow discharge state, an LED (63), and a controller (65). When the lamp voltage measured by the lamp voltage measurer (59) is a predetermined value or higher, the controller (65) judges that the possibility of problems occurring in the high pressure lamp is high, and lights the LED (63).
