Description

200839416 IX. DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to a projector. [Prior Art] Conventionally, there has been known a projector including a light source device, a light modulation device that modulates a light beam emitted from a light source device based on image information to form image light, and a projection optical device that enlarges projected image light. In the projector, a light-emitting type light source device is often used. The light source I includes, for example, a light source lamp that discharges light between a pair of electrodes, and a reflection that emits a light beam emitted from the light source lamp in a predetermined direction. Further, the light source device generates heat convection due to heat generation due to light emission, and causes a temperature difference between the upper side and the lower side of the light source lamp. Thus, when the temperature distribution of the light source lamp is largely deviated, it is easy to cause blackening of the wall of the light source lamp, etc., causing the brightness of the light source lamp to be lowered or the light source lamp to be broken. Therefore, in order to moderately cool the light source lamp in order to alleviate the temperature difference between the upper side and the lower side of the light source lamp, a technique of blowing air substantially horizontally from the side of the light source lamp by a cooling fan has been proposed (Reference: Japanese special Opened Gazette 2002-23261). The technique described in the above document is designed on the premise that the image light is projected in a substantially horizontal direction, that is, in a so-called normal swing posture (a state placed on a setting surface such as a table) and a hanging posture (suspended from a ceiling or the like). The image is projected from the projector in a state where the phase is opposite to the normal posture. Also 5 200839416 That is, 'projecting image light from the projector regardless of both the posture of the positive posture and the hanging posture' is to blow the air in the horizontal direction to the light source lamp, and to moderate the temperature difference between the upper side and the lower side of the light source & Cool the light source lamp efficiently. However, the technique described in the above document projects image light in a substantially vertical direction (up and down direction), or from a projection position in the upper projection direction (a text projected on the upper side) or a downward projection posture (a posture projected on the lower side). When the machine projects image light, the cooling fan is located on the upper side or the lower side of the light source lamp, and the cooling fan blows air to the light source lamp in the vertical direction. For example, when the air is blown from the lower side toward the upper side by the cooling fan, that is, mainly the lower side of the light source lamp is cooled, causing a large temperature difference between the upper side and the lower side of the light source lamp, and the light source lamp cannot be cooled efficiently. . SUMMARY OF THE INVENTION The main object of the present invention is to provide a projector capable of efficiently cooling a light source lamp in response to projection of image light in various postures. The projector of the present invention includes a light source lamp and a cooling device for cooling the light source lamp. The cooling device includes a plurality of cooling fans that blow air to the light source lamp, and each of the air of the plurality of cooling fans The direction of the air supply is set to a different direction. Here, the plurality of cooling fans may blow air directly to the light source lamp or blow air through the duct. In the present invention, for example, when the image light is projected from the projector in a normal swing or a suspended posture, the xenon air blowing direction of one of the plurality of cooling fans may be first set to the horizontal direction. With this setting, when the image light is projected from the projector in the positive posture 6 200839416 or the hanging posture, by driving the cooling fan, the light source lamp is blown in the horizontal direction to relax the lower side of the upper side of the light source lamp. The temperature difference is to efficiently cool the light source lamp. In addition, since the air supply directions of the air of the plurality of cooling fans are set to be different from each other, the image is projected in the upper projection position or the lower projection = machine, even if the cooling fan is set to the light source=direction system. In the air blowing direction from the lower side to the upper side, = at least one of the other cooling fans is set to be the air blowing side from the upper side toward the lower side: posture is cast::: so 'projecting in the upper or lower projection At least one of the following: when the shirt is like light, by driving the other cooling fan, the second light source lamp is blown from the upper side toward the lower side or along the water, and the ancient side can relax the upper side and the lower side of the light source lamp. , Tian is to efficiently cool the light source. Thanks to the fact that the light source lamp can be efficiently cooled in response to various postures, and the object of the present invention is achieved. In the case of the projector of the present invention, two cooling fans are provided in each of the air blowing directions, and in the viewing direction, the direction of the optical axis of the light beam emitted from the Guanghai light source lamp is observed. ...the direction orthogonal to the optical axis and facing each other, the two cooling fans are arranged to be orthogonal to the well and the k wind direction, and are not limited to the configuration of the light sleeve. The direction of each air supply can be set to the opposite direction of the light::: angle, orthogonal to the angle of the father. 200839416 For example, the projector may be configured to rotate the projector by 9 turns centering on the optical axis of the light beam emitted from the light source lamp. , and can be set to a posture such as a positive swing posture, a j-square technique, a suspension posture, and a lower projection posture. When configured as described above, in the present invention, each of the air blowing directions of the air of the two cooling fans can be configured as described above, so that at least one of the upper cooling fans can be configured as the light source for the light source... The side is directed toward the lower side or blows air in the horizontal direction. As described above, by configuring the projector in the above-described manner, it is possible to efficiently cool the light source lamp in accordance with the case where the image light is projected in the above various postures. -Sportsmanship: Since the cooling device has two cooling fans, it can cool the light source with a minimum number of cooling winds, and the U should efficiently cool the light source in the above various postures. It hinders the miniaturization of the projector. In the projector of the present invention, it is preferable to set the horizontal direction in the direction of the _ _ _ _ _ σ 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 In the direction of each hurricane in this I, when the image light is projected from the projector, the 八 Μ Μ + + + + + + + + + + + + + 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 Thereby, the above is set such that the projector can be rotated by the lp by centering on the optical axis, and the air can be blown by the two of the two cooling fans. In the projector whose side is oriented toward the lower side or in the horizontal direction, 兮 is orthogonal to the respective blowing directions; the wind direction is preferably set to be shifted from each other in the other direction. In the present invention, the wood V is a long time β pi is set in the above-described manner in the beginning of the rain, and therefore, when the fan is driven, the air from the cooling fan and the air from the other cooling fan of 200839416 are not. The μ that the cooling fan blows out does not interfere. That is, it can be controlled so that it can enter the blowing outlet of the cooling fan from ::: two. Such as light source lights. Moreover, since the two people transport the air, it is more efficient to cool the air that has been heated from a cooling fan, that is, through the light source lamp, into the mouth, so that it can prevent each person, the bath... The blowing of the fan π stops the cooling fan of each cold part due to heat deterioration. Preferably, in the projector of the present invention, two of the cooling fans are provided; and each of the ones is inspected to be in a direction orthogonal to the optical axis and positive to each other.

As described above, by configuring the projector in the above-described manner, it is possible to efficiently cool the light source lamp in accordance with the case where the image light is projected in the above various postures. Further, since the cooling device is provided with two cooling fans, it is possible to efficiently cool the light source lamp with a minimum number of cooling fans in accordance with the case of 200839416 in which the image light is projected in the above various postures, without hindering the miniaturization of the projector. In the projector of the present invention, each of the air blowing directions is set to a vertical direction or a horizontal direction when the image light is projected from the projector in a predetermined posture. In the present invention, the air blowing directions of the plurality of cooling fans are in the security situation. (for example, a positive posture) when the image light is projected from the projector, it is defined as a vertical direction or a Γ direction orthogonal to each other when viewed from the direction of the optical axis. Thereby, the projector is set as described above so that the projector can be rotated by 9G with the optical axis as the center.
