Beschreibung
Zusammenfassung:	A planar light source device (100) provided with laser light sources (21, 22), first light-guide elements (40, 50), and a second light-guide element (70). The laser light sources (21, 22) emit laser light beams. The first light-guide elements (40, 50) mix the plurality of laser light beams (25, 26) emitted from the laser light sources (21, 22) and convert the plurality of laser light beams (25, 26) into linear light. The second light-guide element (70) receives the linear light and converts the linear light into planar light. The laser light sources (21, 22) are disposed in regions (48, 58) separated by the first light-guide elements (40, 50). The planar light source device (100) radiates heat released in the regions (48, 58) from the laser light sources (21, 22). 面光源装置(100)具有激光光源(21、22)、第1导光元件(40、50)及第2导光元件(70)。激光光源(21、22)射出激光光线。第1导光元件(40、50)将从激光光源(21、22)射出的多条激光光线(25、26)混合而转换成线状的光。第2导光元件(70)射入线状的光而转换成面状的光。激光光源(21、22)配置在由第1导光元件(40、50)隔离出的区域(48、58)内。面光源装置(100)散发从激光光源(21、22)释放到区域(48、58)内的热量。
