Abstract
【課題】複数のLEDチップを有する光取出効率に優れた発光装置を提供する。
【解決手段】本発明の一態様に係る発光装置1は、チップ基板2aと発光層を含む結晶層2bとを含み、直列に配置された複数のLEDチップ2を有し、複数のLEDチップ2のうちの任意のLEDチップ2において、隣接する他のLEDチップ2に向いたチップ基板2aの側面S1は、チップ基板2aの全ての側面のうちで最も劈開性の強い面である。
【選択図】図1
Description
図1(a)、(b)は、それぞれ第1の実施の形態に係る発光装置1の垂直断面図と上面図である。図1(a)の断面は、図1(b)の線分A−Aに沿った断面である。
第2の実施の形態は、任意のLEDチップから隣接する他のLEDチップに向かって放射される光を低減する手段において、第1の実施の形態と異なる。なお、第1の実施の形態と同様の点については、説明を省略又は簡略化する。
第3の実施の形態は、LEDチップの結晶方位において、第1の実施の形態と異なる。なお、第1の実施の形態と同様の点については、説明を省略又は簡略化する。
上記実施の形態によれば、任意のLEDチップから隣接する他のLEDチップに向かって放射される光を低減することにより、LEDチップ間での光吸収による光損失を低減し、発光装置の光取出効率を向上させることができる。
