摘要： Aspects of the invention can provide a lamp device that is capable of avoiding concentration of stresses in a sub-mirror fixing portion of an arc tube. The lamp device can include an arc tube provided with a bulb portion encapsulating inside a pair of electrodes, and a pair of sealing portions formed continuously from the bulb portion and sealing inside electrode axes having the electrodes at tip ends and conductor foils to bring the electrode axes into conduction, a main reflection mirror, to which the sealing portion is fixed, to reflect lights emitted from the arc tube toward an illuminated region, and a sub-mirror fixed to the sealing portion in such a manner that a reflection surface opposes the main reflection mirror with the bulb portion in between. The sub-mirror can be bonded with a bonding agent to a surface region of the sealing portion present in a direction moving away from the bulb portion in reference to a position corresponding to a termination of the electrode axis.

摘要： A light source device includes a light-emitting tube and a reflector. The light-emitting tube has a light-emitting portion that generates a light beam by an electric discharge between electrodes, and sealing portions provided on both sides of the light-emitting portion. The light-emitting tube has a sub-reflection mirror that covers substantially a front half of the light-emitting portion. The reflector has a neck portion provided with an insertion hole to which the light-emitting tube is inserted, and a reflecting portion integrally formed with the neck portion and having an ellipsoidal curved reflecting surface that irradiates the light beam emitted by the light-emitting portion to align the light beam in a predetermined direction. The opening diameter of the insertion hole on the side of the reflecting surface is greater than the external diameter of the sub-reflection mirror and within the internal diameter of a valid reflection area of the reflector.

摘要： A tubular body having a substantially rectangular cross-section is formed with a plurality of flat plates each having a surface with a light reflecting coating applied thereto. To form the tubular body, the flat plates are disposed in such a manner that the surfaces having the light reflecting coating applied thereto face inward and that an end surface of one of the flat plates at one end is held in contact with the surface of another flat plate. The flat plates are bonded by bonding the end portions thereof with each other on the outer side surfaces of a tubular body so as to form an optical rod.
