Abstract:
A direct-type vehicle headlamp module, including a radiator, a light-emitting diode (LED) chip, and a lens, the radiator and the lens are fixed to form an accommodating cavity for accommodating the LED chip, the LED chip is fixed on the radiator, a light ray emitted by the LED chip is directly emitted through the lens, an outer surface of the lens is divided into three areas, curved surface shapes of outer surfaces of the areas are different from each other, a curved surface shape corresponding to a first area is configured to form a cut-off line shape, a curved surface shape corresponding to a second area is configured to increase brightness of a central area of a light shape, and a curved surface shape corresponding to a third area is configured to broaden the light shape. Transmission and emergence directions of the light ray having different curved surface shapes to form the cut-off line shape.
