< Topic >By color temperature and the fact that color rendering property is made high, the illuminating for the aquarium which is suited for also the admiration of the fresh water fish and the water plant etc not only rearing the water plant is offered.SolutionsThe illuminating 1 for the aquarium which has the LED illuminant 3, at least one which at least possesses peak wavelength in the range of one where the LED illuminant 3 consists of the fluorescent substance which the light of LED and said LED compared to gives out the light of long wave long side, consists of the fluorescent substance which at least light of one which possesses peak wavelength in the range of 440nm - 465nm 1st white LED (CW) and LED and said LED compared to gives out the light of long wave long side, possesses peak wavelength in the range of 600nm - 650nm 2nd white LED (WW) and 470nm - 525nm monochromaticity LED and,As for light of implication and the LED illuminant 3, color temperature is 8000K - 12000K, at the same time general color rendering index 85 - 100 features that is.< Choice figure >Drawing 1【課題】色温度および演色性を高くすることで、水草の育成だけでなく淡水魚や水草等の観賞にも適したアクアリウム用照明装置を提供する。【解決手段】LED光源3を備えたアクアリウム用照明装置1であって、LED光源3は、LEDおよび該LEDの光よりも長波長側の光を発する蛍光体からなり、440nm~465nmの範囲にピーク波長を有する少なくとも1つの第1白色LED(CW)と、LEDおよび該LEDの光よりも長波長側の光を発する蛍光体からなり、600nm~650nmの範囲にピーク波長を有する少なくとも1つの第2白色LED(WW)と、470nm~525nmの範囲にピーク波長を有する少なくとも1つの単色LEDと、を含み、LED光源3の光は、色温度が8000K~12000Kであり、かつ平均演色評価数が85~100であることを特徴とする。【選択図】図1
