Abstract
【解決手段】色温度が相対的に低く、目立ち指数FCIが高い光を照射する第1光照射部21と、暗所視輝度及び明所視輝度の比率であるS/P比が相対的に高い光を照射する第2光照射部22とを備える。第1光照射部21は、第2光照射部22よりも鉛直方向において上側の領域を照射する構成とされる。
【選択図】図1
Description
図1(a)に示すように、本実施形態の照明装置10は、地面に一部が埋設されて立設される略円柱状の支柱11と、この支柱11の一端側に取着される照明本体部12とで構成される。照明本体部12は、ハウジング12a内に複数(例えば6個)の第1光照射部21と複数(例えば3個)の第2光照射部22とを備える。照明本体部12は、人H及び街路樹Tの高さよりも低い位置から光を照射するものである。
ここで、第1光照射部21は、第2光照射部22よりも鉛直方向上側に配置される。このため、第1光照射部21から照射された光は、第2光照射部22の光と比較して鉛直方向上側のエリアA1(図2(a)(b)参照)に照射される。そして第1光照射部21の光は、図3及び図4に示す色温度が概ね同じ高演色電球色LEDよりも目立ち指数FCIが高いため、エリアA1に位置する街路樹Tの葉等を鮮やかに見せることが可能となる。
(1)色温度が相対的に低く、目立ち指数FCIが高い光を照射する第1光照射部21と、暗所視輝度及び明所視輝度の比率であるS/P比が相対的に高い光を照射する第2光照射部22とを備える。第1光照射部21は、第2光照射部22よりも鉛直方向において上側の領域(エリアA1)を照射する構成とされる。このような構成とすることで、第1光照射部21により相対的に鉛直方向上側の領域を色温度が低く目立ち指数FCIが高い光で照射するため、街路樹Tやその葉等を鮮やかに見せることができる。また、第2光照射部22により相対的に鉛直方向下側の領域をS/P比が高い光で照射するため、街路樹T近傍が薄明視環境であっても街路樹Tの下方の明るさ感を向上させ、視認性を確保できる。
・上記実施形態では、特に言及していないが、例えば、第1光照射部21と第2光照射部22との照射方向を異なる方向とすることで、第1光照射部が第2光照射部よりも鉛直方向において上側の領域を照射する構成としてもよい。このような構成とした以下の例が考えられる。
(構成A1)高演色電球色LEDに570nm前後の波長域を吸収するネオジウムガラスフィルタを組み合わせる。
(構成A3)高演色電球色LEDにAlInGaP系赤色LEDを組み合わせる。
(構成B1)窒化ガリウム系青色LEDにYAG系黄色蛍光体を組み合わせる。
(構成B3)窒化ガリウム系青色LEDにYAG系黄色蛍光体を組み合わせる。
(イ) 請求項1又は2に記載の照明装置において、
前記第1光照射部の照射する領域と前記第2光照射部の照射する領域の鉛直方向における上下関係は変わらない状態で、前記第1光照射部と第2光照射部との少なくとも一方の照射位置を変更可能な照射位置変更手段を備えたことを特徴とする照明装置。
Claims (2)
