Sensor Lens Housing With Ring Mirror Structure to Prevent Flare

A light blocking layer is introduced as an intermediary component between the sensing module and the housing inner side. This layer selectively blocks stray light from reaching the sensor while allowing the sensing module structure to remain relatively simple. The light blocking layer acts as a mediator that prevents the harmful interaction between stray light and the sensor without requiring complete redesign of the housing structure.

The housing structure is segmented into multiple functional zones: the sensing module area, the light blocking layer area, and the housing inner wall area. By dividing the space and introducing the light blocking layer as a separate segment, the patent prevents flare without requiring complete structural redesign. The segmentation allows each component to perform its specific function while maintaining overall manufacturing feasibility.

The patent changes the optical parameters of the housing by introducing a light blocking layer with specific optical properties (light-absorbing or light-blocking characteristics). This parameter change prevents flare phenomenon while the layer can be integrated using existing manufacturing processes such as coating, lamination, or insertion of pre-fabricated light-blocking components, thus maintaining ease of manufacture.

The light blocking layer can be implemented as a relatively simple, potentially disposable component that is easier to manufacture than complex structural modifications. It can be applied as a coating or inserted as a simple barrier element that prevents flare without requiring permanent, complex structural changes to the housing, thereby maintaining manufacturing simplicity while improving optical performance.
