Title (EN) LIGHT SOURCE DEVICE AND PROJECTION DISPLAY APPARATUS
(FR) DISPOSITIF DE SOURCE LUMINEUSE ET APPAREIL DE PROJECTION
(JA) 光源装置及び投写型表示装置
Abstract:
(EN) Disclosed is a projection display apparatus wherein the efficiency of utilization of light is high, the illuminance uniformity on the screen is also high, and the life of the light source device is prolonged. In the light source device (10) of the projection display apparatus, a first light source lamp (11), a second light source lamp (12), and a relay optical system (13) are arranged in such a way that there is not a part where the optical axes (11c1, 11c2, 11c3) of a first light beam (L1) from the first light source lamp (11) through the relay optical system (13) to the entrance end (15a) of a light intensity equalizing element (15) and the optical axis (12c) of a second light beam from the second light source lamp (12) to the entrance end (15a) agree with one another, and the optical axis (11c3) of the first light beam (L1) immediately before the first light beam (L1) enters the entrance end (15a) and the optical axis (12c) of the second light beam (L2) from the second light source lamp (12) to the entrance end (15a) are substantially parallel to each other.
(FR) La présente invention concerne un appareil de projection dont le rendement d'utilisation de lumière est élevé, l'uniformité d'éclairement lumineux est également élevée, et la durée de vie du dispositif de source lumineuse est prolongée. Dans le dispositif de source lumineuse (10) de l'appareil de projection, une première lampe de source lumineuse (11), une seconde lampe de source lumineuse (12), et un système de relais optique (13) sont agencés de telle manière qu'il n'y a pas une partie où les axes optiques (11c1, 11c2, 11c3) d'un premier faisceau lumineux (L1) provenant de la première lampe de source lumineuse (11) via le système de relais optique (13) et se dirigeant vers l'extrémité d'entrée (15a) d'un élément égalisateur d'intensité lumineuse (15), et l'axe optique (12c) d'un second faisceau lumineux provenant de la première lampe de source lumineuse (11) et se dirigeant vers l'extrémité d'entrée (15a), ne s'accordent mutuellement. L'axe optique (11c3) du premier faisceau lumineux (L1) immédiatement avant le premier faisceau lumineux (L1) entre dans l'extrémité d'entrée (15a), et l'axe optique (12c) du second faisceau lumineux (L2) provenant de la seconde lampe de source lumineuse (12) vers l'extrémité d'entrée (15a) sont sensiblement parallèles.
(JA)  光利用効率が高く、スクリーン上の照度均一性も高く、光源装置の長寿命化を実現できる投写型表示装置であって、この投写型表示装置の光源装置(10)において、第1の光源ランプ(11)からリレー光学系(13)を経由して光強度均一化素子(15)の入射端(15a)に至る第1の光束(L1)の光軸(11c1,11c2,11c3)と第2の光源ランプ(12)から入射端(15a)に至る第2の光束の光軸(12c)とが一致する部分を持たないように、且つ、入射端(15a)に入射する直前での第1の光束(L1)の光軸(11c3)と第2の光源ランプ(12)から入射端(15a)に至る第2の光束(L2)の光軸(12c)とが、互いに略平行な方向となるように、第1の光源ランプ(11)、第2の光源ランプ(12)、及びリレー光学系(13)を配置した。
