The invention relates to an LED (light emitting diode) light-mixing efficient energy-saving street lamp which is characterized in that a high-voltage sodium lamp (1) is installed in a high-voltage sodium lamp reflector (3); the high-voltage sodium lamp reflector (3) is installed in a light-mixing street lamp (4); LED lamps (2) are installed on lower shells of the light-mixing street lamp (4) at the periphery of the high-voltage sodium lamp reflector (3); and a plurality of LED lamps (2) which adopt the light-mixing street lamp (4) as a mounting base point are annularly distributed at the periphery of the high-voltage sodium lamp reflector (3). The commercial power of AC220V is connected with a power supply input end of an electronic ballast; the electronic ballast is provided with two output ends, one end is connected with the high-voltage sodium lamp (1), and the other end is connected with the LED lamps (2); after the light of the LED lamps and the high-voltage sodium lamp is mixed,the warm and white light is obtained, and the middle visual brightness of human eyes and the color rendering property are improved. By replacing the traditional inductive ballast through the electronic ballast which has time control on power, the integral energy-saving effect of the lamp is greatly improved.
