摘要： An optical lens module includes a lens element and an adjustable aperture module disposed at object side of the lens element, and the adjustable aperture module includes a blade assembly and a driving component. The blade assembly includes rotatable blades disposed around an optical axis of the lens element to form a light passing aperture. Each rotatable blade includes a rotatable portion and a light blocking portion. The light blocking portion extends and tapers away from the rotatable portion. The rotatable portion has a positioning hole and a dynamic hole. The positioning hole enables rotation of the rotatable blade, and the dynamic hole is disposed close to the positioning hole. The driving component includes a rotatable element corresponding to the dynamic holes to rotate the rotatable blades, to thereby vary aperture size. The light blocking portion includes a protruding segment which extends and tapers toward the light passing aperture.

摘要： An imaging lens module includes a lens element having an optical axis, a lens carrier and a variable through hole assembly. The lens carrier accommodates the lens element and sequentially includes an object-side portion, an image-side portion and a tubular portion. The object-side portion configured for light entering the imaging lens module forms a minimum opening of the lens carrier. The variable through hole assembly is disposed on the object-side portion and includes rotatable blades rotatably disposed about the optical axis and configured to form a through hole with a variable size. Moreover, the object-side portion further has a guiding structure guiding the movement of the rotatable blades and located further away from the optical axis than the minimum opening. Moreover, the object-side portion and the image-side portion form an air sleeve therebetween, and the air sleeve is located further away from the optical axis than the tubular portion.
