Abstract
(EN) This image display apparatus is provided with a light source section, an image generating section, a projection section, a housing section, a first sensor, and a control section. The light source section includes a light source unit having one or more solid-state light sources. The image generating section generates an image on the basis of light emitted from the light source unit. The projection section projects the image generated by means of the image generating section. The housing section has: an outer frame section that surrounds the light source section, the image generating section, and the projection section; and an air inlet, which is formed in the outer frame section, and through which outside air is taken in. The first sensor is disposed close to the air inlet, and measures, as outside temperature, the temperature of the outside air taken in through the air inlet. The control section controls output of the one or more solid-state light sources on the basis of the outside temperature measured by means of the first sensor.
(FR) Le dispositif d'affichage d'image de l'invention est muni d'une partie source lumineuse, d'une partie génération d'image, d'une partie projection, d'une partie boîtier, d'un premier capteur, et d'une partie commande. Ladite partie source lumineuse contient une unité source lumineuse possédant une ou plusieurs sources lumineuses à semi-conducteurs. Ladite partie génération d'image génère une image à l'aide d'une lumière provenant de ladite unité source lumineuse. Ladite partie projection projette l'image générée par ladite partie génération d'image. Ladite partie boîtier possède une partie enveloppe externe entourant ladite partie source lumineuse, ladite partie génération d'image et ladite partie boîtier, et un orifice d'admission formé dans ladite partie enveloppe externe, et admettant l'air d'une partie externe. Ledit premier capteur est disposé à proximité dudit orifice d'admission, et mesure en tant que température de partie externe, la température de l'air de ladite partie externe admis par ledit orifice d'admission. Ladite partie commande effectue une commande à la fois de ladite température de partie externe mesurée par ledit premier capteur, et de la sortie de ladite ou desdites sources lumineuses à semi-conducteurs.
(JA)  この画像表示装置は、光源部と、画像生成部と、投射部と、筐体部と、第1のセンサと、制御部とを具備する。前記光源部は、1以上の固体光源を有する光源ユニットを含む。前記画像生成部は、前記光源ユニットからの光をもとに画像を生成する。前記投射部は、前記画像生成部により生成された画像を投射する。前記筐体部は、前記光源部、前記画像生成部、及び前記投射部を囲む外枠部と、前記外枠部に形成され外部の空気を吸入する吸気口とを有する。前記第1のセンサは、前記吸気口の近傍に配置され前記吸気口から吸入された前記外部の空気の温度を外部温度として測定する。前記制御部は、前記第1のセンサにより測定された前記外部温度をもとに、前記1以上の固定光源の出力を制御する。
