  • Outer lens for lighting fixtures for vehicles, lighting fixture for vehicles provided with said outer lens, and method for producing said lighting fixture for vehicles
    Patent number: 11371673
    Abstract: An outer lens for a lighting fixture for a vehicle includes a first region formed of a first material and a second region formed of a second material adjacent to the first region. The first material transmits light in a visible light range. The second material has a first wavelength range with transmittance equal to or less than a first transmittance. A second wavelength range has a transmittance equal to or more than a second light transmittance. A third wavelength range is between the first wavelength range and the second wavelength range. The first wavelength range includes a visible light at an S wavelength or a shorter wavelength. The second wavelength range includes a wavelength range from an M wavelength to an L wavelength. The third wavelength range increases from the S wavelength to the M wavelength. The first wavelength range includes the emission wavelength.
