照明器具は、さまざまな生活シーンへ対応するため自然光（太陽光の朝日・夕日で2000K、昼間6,500K) に近い光色切り替え範囲を再現し、さらに細かい作業や文字の読み書きをするという生活シーンで多く使用される昼光色で、明るさ感や演色性の変化を感じられる照明器具を提供することが課題になっている。   Lighting equipment reproduces the light color switching range close to natural light (2000K in the sunrise and sunset of the sun, 6,500K in the daytime) in order to respond to various living scenes, and performs more detailed work and reading and writing characters. It has been an issue to provide a lighting fixture that can be used in daylight, which is often used, and that exhibits a change in brightness and color rendering.

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-mentioned problems and to provide light that can be used to feel a change in brightness and color in a neutral white color (correlated color temperature of 4,600K to 5,500K) that is often used in daily life scenes. .

相関色温度6,500Kと相関色温度2,700Kと相関色温度2,000Kの３色のＬＥＤを搭載し、相関色温度2,700K〜6,500Kの範囲は、相関色温度6,500Kと相関色温度2,700KＬＥＤの２色で構成し、照明器具の最大光量時を相関色温度5,000K付近に設定し、相関色温度2,000KＬＥＤを追加することを特徴とする。   Equipped with three colors of LED with correlated color temperature of 6,500K, correlated color temperature of 2,700K and correlated color temperature of 2,000K, the range of correlated color temperature from 2,700K to 6,500K is correlated color temperature of 6,500K and correlated color temperature of 2,700K LED. It is characterized by comprising two colors, setting the maximum light quantity of the lighting fixture to around 5,000K of correlated color temperature, and adding 2,000K LED of correlated color temperature.

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。   According to the configuration of the present invention, light colors that can be reproduced are in a range of 2,000K to 6,500K, and a color temperature range of 2,000K to 6,500K close to sunlight can be reproduced.

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 5,000K constituted by two colors of a correlated color temperature of 6,500K and a correlated color temperature of 2,700K LED and at a correlated color temperature of 5,000K added with a correlated color temperature of 2,000K LED.

さらに、前記光源カバー７を覆う乳白プラスチック製の透光カバー８を、前記カバー取付具２により保持する。   Further, a translucent cover 8 made of milky plastic, which covers the light source cover 7, is held by the cover fixture 2.

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 lighting fixture.

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 K LED 4 and the correlated color temperature of 2,700 K LED 5 are lit, and the emission intensity near 450 nm of blue is prominent, and the color of red is gradually reduced from red 620 nm to 750 nm with the orange peak at 590 nm to 620 nm. Indicates a change.

発光スペクトル１０は相関色温度6,500KＬＥＤ４と相関色温度2,700KＬＥＤ５、相関色温度2,000KＬＥＤ６の点灯時を示すが、青色の450nm付近は前記スペクトル９と同様の発光強度を示すが、赤色寄りは相関色温度2,000KＬＥＤ６を追加したことで橙色590nm〜620nmの強度が向上し、赤色620nmから750nmまでなだらかに下る変化を示す。   The emission spectrum 10 shows the time when the correlated color temperature of 6,500KLED4, the correlated color temperature of 2,700KLED5, and the correlated color temperature of 2,000KLED6 are lit. The vicinity of 450 nm of blue shows the same luminous intensity as the spectrum 9, but the reddish color shows the correlated color. The addition of the temperature 2,000K LED 6 improves the intensity of the orange color from 590 nm to 620 nm and shows a gradual change from the red color of 620 nm to 750 nm.

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。   Thus, by adding the correlated color temperature of 2,000 KLED 6, an orange wavelength component of 590 nm to 620 nm is added, and the color rendering properties are improved.

また、相関色温度6,500KＬＥＤ４と相関色温度2,700KＬＥＤ５、相関色温度2,000KＬＥＤ６を各々制御することで、最大光量を相関色温度5,000Kに調整する。   Further, the maximum light quantity is adjusted to the correlated color temperature of 5,000 K by controlling the correlated color temperature of 6,500 K LED 4, the correlated color temperature of 2,700 K LED 5, and the correlated color temperature of 2,000 K LED 6, respectively.
