The invention relates to the technical field of holographic projection, in particular to a holographic projection illumination structure for a vehicle. An inner cavity is formed after the front cover shell and the rear cover shell are installed, a holographic sheet back plate is installed in the inner cavity, and a holographic screen sheet is installed on the holographic sheet back plate. A printed circuit board (PCB) is installed below the front housing, an LED module is installed on the PCB, an LED module lens support is arranged on the LED module in a covering mode, and the holographic projection sheet is located above an LED module lens. The light emitting and focusing processes can be completed by applying the optical structure of the single lens and the LED module, so that the whole structure is fully simplified and optimized; the LED module is used for emitting light, so that the power consumption is obviously superior to that of a laser; a heat dissipation piece is additionally arranged for heat dissipation, and space is saved; the surface of the holographic sheet is coated with special optical cement, a designed light path is etched on the cement through photoetching equipment, and the LED module is lightened, so that a holographic pattern is presented on the surface; and the adaptability is high.

    本发明涉及全息投影技术领域,尤其是一种车用全息投影照明结构。前罩壳与后罩壳之间安装后形成内腔,该内腔中安装有全息片背板,全息片背板上安装有全息投影片;前罩壳的下方安装有PCB线路板,PCB线路板上安装有LED模组,LED模组上罩设有LED模组透镜支架,全息投影片位于LED模组透镜的上方。运用单组透镜,LED模组的光学结构,就可以完成发光和聚焦的过程,使得整体结构得到充分简化优化;采用LED模组发光,在功耗上比激光器有明显优势;加散热件散热,实现空间的节省;全息片表面涂有特殊光学胶,通过光刻设备将设计的光路刻蚀在胶上,点亮LED模组,从而在表面呈现全息图案;适应性较强。
