Claims (4)
- 上面に発光面及び電極が設けられたLEDチップを回転テーブル上に置き、当該LEDチップの光を受光手段で受光し、この受光手段の出力結果に基づいてLEDチップの光の光学特性を測定する光学特性測定装置において、
LEDチップの発光面と対向しており且つLEDチップの光を受光手段に集める集光器を備えており、
集光器は、受光手段が覗いており且つLEDチップの各方向の光の光束を集めて当該受光手段に入射させるために内壁面に拡散反射性を有した下面開口の略球面状の凹部が設けられており且つ前記電極に接触するプローブピンが挿入されるスリットが形成されていることを特徴とする光学特性測定装置。 - 上面に電極が、下面に発光面が設けられたLEDチップを回転テーブル上に置き、当該LEDチップの光を受光手段で受光し、この受光手段の出力結果に基づいてLEDチップの光の光学特性を測定する光学特性測定装置において、
LEDチップが置かれる部分が少なくとも透明であるプレートと、
このプレートを挟んでLEDチップの発光面と対向しており且つLEDチップの光を受光手段に集める集光器と、
LEDチップを挟んで前記集光器と対向する反射部材とを備えており、
集光器は、受光手段が覗いており且つLEDチップの各方向の光の光束を集めて当該受光手段に入射させるために内壁面に拡散反射性を有した上面開口の略球面状の凹部が設けられており、
この反射部材は、LEDチップの光を集光器の凹部に向けて反射させるために内壁面に拡散反射性を有した下面開口の略半球面状の凹部が設けられており且つ前記電極に接触するプローブピンが挿入されるスリットが形成されていることを特徴とする光学特性測定装置。 - 請求項1又は2記載の光学特性測定装置において、
前記集光器の凹部内には、LEDチップと受光手段との間に位置し、LEDチップの光が受光手段に直接入射するのを遮蔽する遮蔽物が設けられており、
この遮蔽物の外周面はLEDチップの光を前記凹部に反射させるために拡散反射性を有していることを特徴とする光学特性測定装置。 - 請求項3記載の光学特性測定装置において、
前記遮蔽物は略球体であることを特徴とする光学特性測定装置。
