Description
異なる波長の光を発する複数の光源が発した光を合成した合成光を出力する合成光出力部と、
前記光源が発した熱を放散する放熱器と、
を備え、前記合成光によって虚像を表示するヘッドアップディスプレイ装置であって、
前記複数の光源は、第1動作保証温度帯域で動作する第1光源と、前記第1動作保証温度帯域よりも上限が高い第2動作保証温帯域で動作する第2光源と、を有し、
前記第1光源は、前記第2光源に比べ前記放熱器上の放熱性の高い箇所に設けられ、
前記放熱器は、高熱伝導性樹脂で射出成形され、前記第1光源と前記第2光源が配置される箇所の間にウェルドラインが形成される、
ように構成する。
このように構成することで、異なる波長の光を発する複数の光源が発する熱を効率的に放熱できる。
このように構成することで、第2動作保証温帯域で動作する第2光源11bが発した熱が第1動作保証温度帯域で動作する第1光源11aに伝わることを抑制でき、異なる波長の光を発する複数の光源が発する熱を効率的に放熱できる。
