摘要： A light-source lamp unit includes a light-source lamp unit detachably mounted, and a CPU constituting a drive and controller for the light-source lamp unit. The CPU senses lamp information obtained by a lamp-information storing block in the light-source lamp unit, pertaining to a lamp power rating, lamp life and whether a lamp is new or not, and starts counting operation time when the lamp is lit. The CPU compares the lamp life sensed and the operation time count, and forces the lamp to extinguish when the life of the light-source lamp expires. Prior to this action, the CPU gives a warning display before the life expiration of the lamp by a fixed duration of time, to warn that lamp replacement is needed. Because the lamp-information storing block in the light-source lamp unit stores the information about the lamp type and characteristics of the lamp, the light-source device can properly drive the lamp to light it and determine the lamp life even when a light-source lamp unit of a different type is used.

摘要： A light-source lamp unit 100 includes a light-source lamp unit 1 detachably mounted, and CPU 101 constituting drive and control means for the light-source lamp unit. CPU 101 senses the lamp information borne by lamp-information storing block 5 in the light-source lamp unit 1, about a lamp power rating, lamp life and whether a lamp is new or not, and starts counting operation time when the lamp is lit. CPU 101 compares the lamp life sensed and the operation time count, and forces the lamp to extinguish when the life of the light-source lamp expires. Prior to this action, CPU 101 gives a warning display at a time that is earlier than the life expiration of the lamp by a fixed duration of time, to warn that a lamp replacement is needed. Since the lamp-information storing block 5 in the light-source lamp unit 1 stores the information about the lamp type and characteristics of the lamp, the light-source device 100 can properly drive the lamp to light it and determine the lamp life even when a light-source lamp unit of a different type is used.

摘要： A projection display device projector capable of improving cooling efficiency of the power unit includes a light source lamp unit, a projection lens unit, an exhaust fan provided near the light source lamp unit for ventilating an outer case, and a ventilating path provided inside the power unit. A suction fan is provided at the inlet of the ventilating path which is connected to the cooling air intake port through a duct cover to directly conduct fresh air into the ventilating path. Because the interior of the power unit is cooled by fresh air which is cooler than the air inside the outer case, cooling efficiency is enhanced.

摘要： In a projection display provided with an optical unit, a power source unit, an external case to store the optical unit and the power source unit, a suction opening (75) is formed in one end part of the power source unit, a discharge opening (77) is formed in the other end part, and the suction opening (75) is arranged in the vicinity of an air inlet in the external case. Because the suction opening (75) and the discharge opening (77) are provided, the inside of the power source unit can be independently and efficiently cooled, and the optical unit and the power source unit can be arranged closely to each other.

摘要： A projector includes a first lens plate having a plurality of lenses, a second lens plate having a plurality of lenses, a light valve that modulates an output light beam from the second lens plate, and a light source apparatus. The light-source apparatus has a light-source lamp including an emission tube, a reflective mirror that reflects a divergent light beam from the light-source lamp to output a parallel light beam, the reflecting mirror having a reflective surface, a lamp housing that supports the reflective mirror, and an electrode lead. The electrode lead is led out of an end of the emission tube that is projected forward out of the reflective surface and is connected to an external connection terminal board which is positioned to a rear side of the reflective surface. The electrode lead is routed via the portion of the reflective mirror other than an effective area of the reflective mirror. A portion of the electrode lead positioned on the side of the reflective surface is arranged along a grove of a lens of the plurality of lenses of one of the first and second lens plate.
