LIGHT SHAPE ADJUSTMENT METHOD FOR ILLUMINATION MODULE, ILLUMINATION MODULE, HEADLAMP AND VEHICLE

WIPO Patent Application WO/2022/256983

A1

An illumination module, a headlamp and a vehicle. The light shape of the illumination module comprises a pixelated light shape (100) and a non-pixelated light shape (200), and the pixelated light shape (100) has an angle difference range of 5° to 8° between upper and lower boundaries. A light shape adjustment method for the illumination module comprises adjusting the position of the pixelated light shape (100), so that in a low beam illumination mode, the lower boundary of the pixelated light shape (100) is in an angle range of greater than or equal to -8° and less than or equal to -4°, and the upper boundary is in an angle range of greater than or equal to 0° and less than or equal to 3°; and in a high beam illumination mode, the lower boundary of the pixelated light shape (100) is in an angle range of greater than or equal to -3° and less than or equal to -1°, and the upper boundary is in an angle range of greater than or equal to 4° and less than or equal to 8°. The light shape adjustment method for the illumination module has simple operations and a good illumination effect, and may reduce the fabrication costs of the illumination module.
