  • Imaging Assembly, Illumination and Projection Apparatus, and Courtesy Lamp
    Publication number: 20230168465
    Abstract: An imaging assembly includes a first lens, a second lens, and a third lens. The imaging assembly satisfies the following relational expressions: 0.9<|f2/f|<2.4 and 0.23<?11/TTL<0.45. The illumination and projection apparatus includes the imaging assembly, a housing with a light inlet and a light outlet, and an illumination assembly disposed in a first accommodating space of the housing. The imaging assembly is clamped in a second accommodating space of the housing. The imaging assembly blocks the light outlet, and the illumination assembly blocks the light inlet, which improves sealing performance of the illumination and projection apparatus. An aperture of the second accommodating space is smaller than an aperture of a first accommodating space, which facilitates installation of the imaging assembly and the illumination assembly, and improves convenience of installing the illumination and projection apparatus.
