The invention discloses a high CRI LED lamp and a design method thereof. According to the design method, under the premise that conventional LEDs are used, the CRI of the LED lamp can be greatly improved through the luminous flux matching ratio of the LEDs of different colors. The CRI of the LED lamp which is manufactured by the method can reach 95, the structure is simple, manufacturing is convenient, and the cost is low. According to the design method, the CRI of one single white light LED does not need to be improved, the high CRI LED lamp can be manufactured only by common LEDs in the market, and the limitation for manufacturing high CRI LED lamp chips and for packaging processes is reduced. The design method can be implemented at a lamp application terminal, so that the downstream of the LEDs, namely the LED lamp application terminal has more autonomy for developing the high CRI lamps, the method does not depend on upstream chips and packaging, and the high CRI lamp development cost is greatly reduced at the same time.
