Abstract
An exemplary lens module includes a barrel receiving a lens system therein, an infrared-cut filter, an infrared-pass filter, and a switching mechanism. The switching mechanism includes a connecting member interconnecting the infrared-cut filter and the infrared-pass filter, a first magnetic member fixed at the barrel, and a second magnetic member fixed at the connecting member. The first and second magnetic members are configured for driving the connecting member to move relative to the barrel so as to selectively bring either the infrared-cut filter or the infrared-pass filter into optical alignment with the lens system in the barrel.

A lens module, comprising:
- a barrel receiving a lens system therein;
- an infrared-cut filter;
- an infrared-pass filter;
- and
- a switching mechanism, comprising:
- a first magnetic member,
- a second magnetic member, and
- a connecting member interconnecting the infrared-cut filter and the infrared-pass filter;
- wherein the first magnetic member is fixed at the barrel, the second magnetic member is fixed at the connecting member and positioned generally opposite to the first magnetic member, and the first and second magnetic members are configured such that magnetic force can be selectively generated or absent therebetween to drive the connecting member to move relative to the barrel so as to selectively bring either the infrared-cut filter or the infrared-pass filter into optical alignment with the lens system in the barrel.

- an infrared-pass filter;
- and
- a switching mechanism, comprising:

- a second magnetic member, and
- a connecting member interconnecting the infrared-cut filter and the infrared-pass filter;
- wherein the first magnetic member is fixed at the barrel, the second magnetic member is fixed at the connecting member and positioned generally opposite to the first magnetic member, and the first and second magnetic members are configured for generating magnetic force therebetween to drive the connecting member to move relative to the barrel so as to selectively bring either the infrared-cut filter or the infrared-pass filter into optical alignment with the lens system in the barrel.
A lens module, comprising:
- a barrel with a lens system received therein;
- an infrared-cut filter;
- an infrared-pass filter;
- and
- a switching mechanism, comprising:
- a first magnetic member,
- a second magnetic member, and
- a connecting member interconnecting the infrared-cut filter and the infrared-pass filter;
- wherein the first magnetic member is fixed at the barrel, the second magnetic member is fixed at the connecting member and positioned generally opposite to the first magnetic member, at least one of the first and second magnetic members is an electromagnet capable of generating magnetic force between the first and second magnetic members when electrified and capable of achieving a state of no magnetic force between the first and second magnetic members when not electrified to drive the connecting member to move relative to the barrel between a first position and a second position, wherein at the first position the infrared-cut filter is in optical alignment with the lens system such that the lens module is capable of capturing visible light images, and at the second position the infrared-pass filter is in optical alignment with the lens system such that the lens module is capable of capturing infrared light images.
