Abstract: With the rapid development of the new energy vehicle industry, one of its key components, the front signal light, has also shown an integrated development trend. This study proposes an innovative multifunctional integration scheme for front signal lights. This solution utilizes a single light-emitting diode (LED) source combined with a rotatable multi-face optical structure, achieving precise switching of light-emitting surfaces through a Hall sensor and stepper motor, thereby integrating multiple lighting and signaling functions within a confined space. Test results demonstrate that the maximum luminous intensities of the structure in low-beam and high-beam modes reach 123 cd and 616 cd respectively. This design not only maintains an exquisite automotive appearance but also effectively saves space, significantly reducing overall manufacturing costs.
