蛍光体を適当な割合で混合して使用する三液長域発光形
蛍光ランプがある。(Prior art) In recent years, there has been a high demand for high color rendering and single-product output for fluorescent lamps for general lighting, and one way to satisfy this demand is to use blue, green, and red light-emitting fluorescent lamps that have a relatively narrow band emission spectrum distribution. There is a three-liquid long-range fluorescent lamp that uses a mixture of three liquids in an appropriate ratio.

(Japanese Patent Publication No. 57-52390) is known. Furthermore, in a three-component long-range fluorescent lamp, the total luminous flux is almost entirely contributed by the green-emitting phosphor, and the performance of the green-emitting phosphor greatly influences the performance of the lamp. However, the performance of the above-mentioned known green-emitting phosphors is not satisfactory, and there is room for improvement in terms of luminance.
