Claim 5:
6. The vehicle headlamp optical system according to claim 5, wherein the dimming system comprises a left-right dimming mechanism and a up-down dimming mechanism, the left-right dimming mechanism comprises a fixed frame and a left-right dimming screw disposed in a left-right direction, and the left-right dimming screw is rotatably mounted on the fixed frame; the up-down dimming mechanism comprises a support frame, a up-down dimming screw disposed in a up-down direction, and a screwed connector in screwed connection with the up-down dimming screw, the support frame is slidably mounted on the fixed frame and is in screwed connection with a screw rod of the left-right dimming screw, the up-down dimming screw is rotatably mounted on the support frame, and the screwed connector is fixed to the heat radiator;
the up-down dimming screw is rotated, and the screwed connector moves up and down to drive the heat radiator to move up and down, so that the heat radiator rotates around a up-down dimming axis to perform up-down dimming; and the left-right dimming screw is rotated, the up-down dimming mechanism moves left and right, and the up-down dimming screw of the up-down dimming mechanism drives the heat radiator to move left and right, so that the heat radiator rotates around a left-right dimming axis to perform left-right dimming.
