  • Patent number: 11781720
    Abstract: A black image type hidden light system applied to a vehicle is composed of a control module coupled to a hidden lamp module in which an outer lens, an inner lens, and a light source are assembled in a lamp housing, and a black color surface of the outer lens covers an inner space of the lamp housing to block the exposure to the outside and transmits the light fully reflected to the inner lens to the outside, thereby forming a deposition image in black when not lit and a lamp image or a lighting image when lit, and in particular, optimizes a light transmittance with an amount of addition of a carbon black material mixed with a polycarbonate (PC) material, thereby substantially enabling the mass-production beyond the limitation of an AL deposition image.
    Type: Grant
    Filed: August 3, 2022
    Date of Patent: October 10, 2023
    Assignees: HYUNDAI MOTOR COMPANY, KIA CORPORATION, HYUNDAI MOBIS CO., LTD.
