  • a third aspect of the present disclosure also provides a headlamp, which comprises the illumination device according to any one of the above-mentioned technical solutions.
  • a fourth aspect of the present disclosure also provides a vehicle, which comprises the headlamp according to the above-mentioned technical solutions.
  • the headlamp optical assembly of the present disclosure includes a light collimating element 1 and a lens mount 2, wherein a cavity suitable for accommodating the light collimating element 1 is formed on the lens mount 2, engagement structures suitable for engagement with each other are formed in the cavity and on the light collimating element 1, and the light collimating element 1 is embedded in the cavity by means of the engagement structures.
  • the headlamp optical assembly of the present disclosure can effectively improve the positioning accuracy between the light collimating element 1 and the lens mount 2, can ensure good light-match performance, improve optical efficiency, and obtain ideal illumination light shape by providing the engagement structures that can be engaged with each other on the light collimating element 1 and the lens mount 2.
  • the light collimating element 1 and the lens mount 2 are preferably integral molded part, and the engagement structures provided on the two can be engaged with each other, which can reduce the installation error between the two, thereby improving the installation accuracy between the light collimating element 1 and the lens mount 2, and ensuring the light-emitting effect.
