An LED light source (100) containing an array (110) of red LEDs and an array (120) of phosphor-coated blue LEDs; the color point from the mixed light emanating from an array (120) of phosphor-coated blue LEDs falls within the quadrangle of the CIE color chart, the coordinates of the four vertices of the quadrangle are (0.375, 0.427), (0.390, 0.456), (0.366, 0.430), (0.38, 0.46); moreover, when the transition temperature of the LEDs from the array (120) of the blue LEDs coated with the phosphor and LEDs from an array of (110) red LEDs, per essentially equal to room temperature, the ratio of the output of the lumens of the array (120) of the phosphor-coated blue LEDs with respect to the output of the lumens of the array (110) of red LEDs is in the range from 4: 1 to 1.5: 1.2. The LED light source (100) according to claim 1, wherein the quantitative ratio and / or the area ratio of the LEDs from the array (120) of the phosphor coated blue LEDs to the LEDs from the array (110) of red LEDs is adjusted so that the ratio of the output of the array lumens (120 ) phosphor-coated blue LEDs with respect to the output of the lumens of the array (110) of red LEDs is in the range from 4: 1 to 1.5: 1.3. The LED light source (100) according to claim 1, wherein the component ratio and / or the granule size of the phosphor is adjusted so that the color point of the mixed light emanating from the array (120) of the phosphor-coated blue LEDs falls within the quadrangle. The LED light source (100) according to claim 1, wherein the wavelength of the radiation peak of the array (120) of the phosphor-coated blue LEDs is set in the range from 440 to 460 nm.
