摘要： An LED (light emitting diode) lighting device with high color rendering index includes a plurality of LED luminous units, wherein one of the LED luminous units has (u′, v′) chromaticity coordinates defined on a 1976CIE chromaticity diagram, a distance between every two coordinate points is not less than 0.01, a distance between at least one of the coordinate points and any other coordinate point is not less than 0.1, and coordinates of at least one of the coordinate points meet a condition that 0.10≦u′≦0.45 and 0.30≦v′≦0.50. By selecting a variety of LEDs within a certain spectral range to mix light, the color rendering index of the LED lighting device with high color rendering index of the present invention can be improved, and simultaneously the cost of the light source can be controlled.
