Title (EN) PROJECTION-TYPE VIDEO DISPLAY DEVICE
(FR) DISPOSITIF D’AFFICHAGE VIDÉO À PROJECTION
(JA) 投射型映像表示装置
Abstract:
(EN) A projection-type video display device that more suitably cools light-emitting diodes of a plurality of colors. A projection-type video display device 100 that uses white light to project video. The projection-type video display device 100 has an LED 111, an LED 112, an LED 113, a cooling unit 114, a cooling unit 115, and a cooling unit 116. LED 111-LED 113 generate white light. Cooling unit 114 cools LED 111. Cooling unit 115 cools LED 112. Cooling unit 116 cools LED 113. LED 111 is the light source that has the largest variation in temperature characteristics. Cooling unit 114, which cools LED 111, is arranged to be cooled more preferentially than cooling units 115, 116.
(FR) L’invention concerne un dispositif d’affichage vidéo à projection qui refroidit plus correctement des diodes électroluminescentes d’une pluralité de couleurs. Elle concerne un dispositif d’affichage (100) vidéo à projection qui utilise la lumière blanche pour projeter une vidéo. Le dispositif d’affichage (100) vidéo à projection comporte une DEL (111), une DEL (112), une DEL (113), une unité de refroidissement (114), une unité de refroidissement (115), et une unité de refroidissement (116). La DEL (111) à la DEL (113) génèrent de la lumière blanche. L’unité de refroidissement (114) refroidit la DEL (111). L’unité de refroidissement (115) refroidit la DEL (112). L’unité de refroidissement (116) refroidit la DEL (113). La DEL (111) est la source de lumière dont la variation de caractéristiques de température est la plus importante. L’unité de refroidissement (114), laquelle refroidit la DEL (111), est agencée pour être refroidie plus préférentiellement que les unités de refroidissement (115, 116).
(JA) 投射型映像表示装置においてより好適に複数色の発光ダイオードを冷却する。投射型映像表示装置100は、白色光を用いて映像を投影する。この投射型映像表示装置100は、LED111、LED112、LED113、冷却ユニット114、冷却ユニット115、および冷却ユニット116を有する。LED111~LED113は、白色光を生成する。冷却ユニット114は、LED111を冷却する。冷却ユニット115は、LED112を冷却する。冷却ユニット116は、LED113を冷却する。LED111は、最も温度特性の変化が大きい光源である。LED111を冷却する冷却ユニット114は、冷却ユニット115,116よりも優先的に冷却されるように配置される。
