The invention discloses an LED (
light emitting diode)
headlamp of an electric automobile, and belongs to the technical filed of
LED illumination. The LED
headlamp of the electric automobile comprises a shell, wherein the shell is provided with a
light source chamber and a heat dissipation air duct; the front surface of the
light source chamber is provided with a seal
glass cover; the
light source chamber is internally provided with a
light reflection cover and a high-power LED module; the highlight emitted by the high-power LED module are gathered within an angle in front through the
light reflection cover; the back surface of the high-power LED module is fixed on the heat absorption end of a
heat pipe radiator; the heat emitted by the LED module during working is transferred from the heat absorption end of the
heat pipe radiator to the heat dissipation end of the radiator; the heat dissipation end of the
heat pipe radiator is provided with intensive heat dissipation fins; and the heat dissipation fins are arranged in the heat dissipation air duct, and the heat is absorbed by blast air generated during the driving process of the automobile. The high-power LED serves as the light source of the
headlamp of the electric automobile, and the LED headlamp of the electric automobile has the advantages of simple structure, high electro-optic conversion rate, energy and
electricity conservation and long service life, and is safe and convenient to use; besides, the independent heat dissipation air duct is adopted, and the heat
pipe radiator and the temperature-controlled heat dissipation fan are arranged, thus the heat emitted out by the LED during working can be guided and dissipated timely, and the problem of
light attenuation generated because of heat emitting in the using process of the LED is solved.
