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 projector is provided which can project a high quality image unaffected by dust, or the like, scattered in the projector by preventing the temperature of light-modulating elements from rising. Light transmissive plates are adhered to the light emitting surface of a liquid crystal panel for red light and the light emitting surface of a liquid crystal panel for green light. The amount of heat transmitted from the polarizing plates, which generate the heat, to the liquid crystal panels is reduced by the light transmissive plates. In addition, dust, scattered in the projector, does not stick onto the light emitting surfaces of the liquid crystal panels. In contrast, a light transmissive plate is not provided at the light emitting surface of liquid crystal panel for blue light having a high energy value per unit quantity of light. Thus, the problem of a light transmissive plate preventing heat dissipation at the liquid crystal panel is eliminated, so that efficient cooling can be achieved. The relative luminosity factor of blue light B is low, so that dust is not noticeable on the screen even when it sticks onto the light emitting surface of the liquid crystal panel.

摘要： A projection lens unit is provided that is reduced in size and profile. The projection lens unit may include a plurality of lenses of which at least one lens disposed at the base end opposite to the projection direction is cut away at the upper portion thereof. The surface of the cut-away portion of the lens is made flat. With this arrangement, a space above the lens can be used when a cooling fan is disposed above an electrooptical unit provided in the vicinity of the projection lens unit, whereby a projector can be reduced in size and profile, because the height of the projector can be reduced because it is not necessary to provide an additional space for receiving the cooling fan in the projector.

摘要： Liquid crystal modulation elements are arranged so that light outgoing surfaces thereof face light incident surfaces of a color synthesizing prism. Transparent plates are bonded to the light outgoing surfaces of the liquid crystal modulation elements. For this reason, adhesion of dust to the light outgoing surfaces of the liquid crystal modulation elements can be prevented. Further, it is possible to prevent light reflection at the interface surface between the light outgoing surfaces and air due to the difference in refractive index therebetween. This allows a high-quality image to be projected without deteriorating the switching characteristic of the liquid crystal modulation elements while preventing dust from adhering to the light outgoing surfaces of the liquid crystal modulation elements.
