HUD ILLUMINATION SYSTEM, HEAD-UP DISPLAY DEVICE AND REALIZATION METHOD

WIPO Patent Application WO/2019/037370

A1

A head-up display (HUD) illumination system (1), a HUD device and a realization method. The system comprises a collimating uniform unit (111) and an intensity distribution adjusting unit (112); the collimating uniform unit is used for converting an incident light source into collimating uniform light beams; the intensity distribution adjusting unit is used for realizing illumination in which different points have different intensity distributions; the collimating light beams of the collimating uniform unit have uniform illumination on cross sections of the light beams; and output light beams of the intensity distribution adjusting unit are matched with an optical imaging system (3) of the HUD. The HUD illumination system is matched with the HUD optical imaging system, so that the illumination light beams are concentrated on an eye box area, and illumination efficiency is improved; compared with a single-lens illumination system, elements of the illumination system are thinner; moreover, the illumination area of the HUD illumination system is not limited to being circular, but also can be rectangular, square, and the like.
