7．3 グレア分類で要求するグレア分類Ｖ，Ｇ1ｂ及びＧ2は，JIS C 8106施設用LED照明器具・施設用蛍光
灯器具，JIS C 8105-3照明器具－第3部：性能要求事項 附属書A“LED照明器具性能要求事項”より次のよう
に定義される。
備 考 1．A断面，B断面を異なったグレア分類で扱ってもよい。
備 考 2．照明器具の輝度は規定された鉛直角における光度（ Iθ）を見掛けの発光面積で除した値とする。
備 考 3．輝度値を算出する“見掛けの発光面積（Aθ，Bθ）”は，次によって算出する。
下面開放器具（ルーバを含む。）及び平板（プリズムを含む。）の透光性カバー付器具は，次の式による。

7．5 輝度値規制形LED高天井用器具の輝度値
輝度値規制形 L E D高天井用器具は，照明カバー等でまぶしさを抑えた器具とし，平均輝度値により
定義する。平均輝度値（cd/m2）は，器具直下における光度 I（cd）を発光部面積 S（m 2）で除した値
とし，輝度値規制形LED高天井用器具中照形の平均輝度値は 350,000（cd/m2）以下とする。
平均輝度値を算出する発光部面積は次により算出する。
（１）照明カバーが一体となった器具
カバー形状が角形の場合 カバー形状が丸形の場合
S = W L S = π（1/2W）2
（２）照明カバーが分割された器具
