In this paper, a study of the design of automotive communication lamps using microlens arrays (MLAs) was conducted. With the development of autonomous driving technology, automobiles need communication lamps to communicate with pedestrians. To reduce the size of the optical system and secure high light intensity, the communication lamp's optical system was designed using an MLA. In addition, to secure a clear image on inclined ground, the design was carried out considering the overlap method. After that, the improved performance was confirmed by comparing it to the MLA optical system before overlapping.
