It is related to lighting equipment that feels the change in brightness and color rendering in the required daylight color.
従来、照明器具に搭載されるＬＥＤ光源は、主にJIS Z 9112に示す昼光色（色温度5,700K〜7,100K）、昼白色（色温度4,600K〜5,500K）、電球色（色温度2,600K〜3,250K）の光色が使用される。
演色性を向上する技術として、色温度6,500KＬＥＤと色温度2,000KＬＥＤに、青色ＬＥＤや赤色ＬＥＤを追加した照明器具（特許文献１）がある。

It is an issue to provide a lighting fixture that can feel a change in brightness and color rendering in the daylight color that is often used.
本発明は、上記を解決し、生活シーンで多く使用される昼白色（相関色温度4,600K〜 5,500K）で、明るさ感や色味の変化を感じられる光を提供することを目的とする。 An object of the present invention is to solve the above problem and to provide a light having a neutral white color (correlated color temperature of 4,600K to 5,500K), which is often used in daily life, and in which a feeling of brightness and a change in color can be felt. ..

It is composed of two colors, the maximum light intensity of the lighting equipment is set to around 5,000K, and the correlation color temperature is 2,000K, and the LED is added.
本発明の構成により、再現できる光色が2,000K〜6,500Kまでの範囲となり、太陽光に近い色温度範囲2,000K〜6,500Kを再現可能となる。 With the configuration of the present invention, the reproducible light color is in the range of 2,000K to 6,500K, and the color temperature range close to that of sunlight is 2,000K to 6,500K.
相関色温度6,500Kと相関色温度2,700KＬＥＤの２色で構成した相関色温度5,000Kと相関色温度2,000KＬＥＤを追加した相関色温度5,000Kで演色性に変化ができる。 The color rendering property can be changed at a correlated color temperature of 5,000 K composed of two colors, a correlated color temperature of 6,500 K and a correlated color temperature of 2,700 KLED, and a correlated color temperature of 5,000 K with the addition of a correlated color temperature of 2,000 KLED.

図2に示すグラフは、前記照明器具の発光スペクトルを示す。 The graph shown in FIG. 2 shows the emission spectrum of the luminaire.
発光スペクトル９は相関色温度6,500KＬＥＤ４と相関色温度2,700KＬＥＤ５の点灯時を示すが、青色の450nm付近の発光強度が突出し、赤色寄りは橙色590nm〜620nmを頂点に赤色620nmから750nmまでなだらかに下る変化を示す。 The emission spectrum 9 shows when the correlated color temperature of 6,500 KLED4 and the correlated color temperature of 2,700 KLED5 are lit, but the emission intensity of blue around 450 nm is prominent, and the reddish color gradually decreases from red 620 nm to 750 nm with orange 590 nm to 620 nm at the apex.

By adding the temperature 2,000KLED6, the intensity of orange 590nm to 620nm is improved, and the red color shows a gradual change from 620nm to 750nm.
これにより、相関色温度2,000KＬＥＤ６を追加することで、橙色590nm〜620nmの波長成分が加わり演色性が向上する。 As a result, by adding the correlated color temperature of 2,000 KLED6, the wavelength component of orange 590 nm to 620 nm is added and the color rendering property is improved.
