Abstract
The embodiment of the utility model discloses a lens module. The lens module comprises a lens tube with a light-through hole at the front end, as well as a front lens unit and a back lens unit which are both arranged in the lens tube, and a double-optical filter switch device arranged between the front lens unit and the back lens unit. According to the lens module, as the double-optical filter switch device is arranged in the lens tube, the tractive force is reduced, and the normal switching between the optical filters is ensured; and besides, as a colored glass part is additionally arranged on an infrared cut-off optical filter, the light-in quantity is reduced, and the problem of exposure caused by excess incoming light in the daytime is solved.
Description
Technical field
The utility model relates to the camera technique field, relates in particular to a kind of camera lens module.
Background technology
Existing video camera or video camera are equipped with two switching device of optical fiber in the camera lens outside usually, can realize the switching of cutoff filter and full spectrum optical glass optical filter, and then guarantee the image quality that day and night is taken.Yet; Two switching device of optical fiber are meticulousr and thin devices, and two switching device of optical fiber are arranged on the camera lens outside, and the tractive force that two switching device of optical fiber receive is bigger; Cause two switching device of optical fiber distortion easily, thereby influence the normal switching of optical filter; And because of evening light a little less than, must add the logical light quantity of macro lens in order to guarantee the night vision effect, but logical light quantity too conference cause advancing daytime light and excessively produce the exposure phenomenon, the quality that influence is taken.
The utility model content
The utility model embodiment technical matters to be solved is; A kind of camera lens module is provided; Can reduce two suffered tractive force of switching device of optical fiber, and then guarantee the normal switching of optical filter, and it is excessive and advance the problem that light excessively produces exposure daytime that cause to solve logical light quantity.
In order to solve the problems of the technologies described above; The utility model embodiment has proposed a kind of camera lens module; Comprise that front end is provided with the barrel of light hole, is arranged at said barrel inner front lens unit and rear lens unit, also is provided with two switching device of optical fiber between said front lens unit and rear lens unit.
Further, said pair of switching device of optical fiber comprises:
The cutoff filter that is used for the filtering IR;
Full spectrum glass filter;
Thereby be connected with external drive circuit, drive cutoff filter and full spectrum glass filter and in barrel, move and make cutoff filter or the full spectrum glass filter switching mechanism relative with said light hole.
Further, said cutoff filter comprises: infrared ray optical filtering portion that is oppositely arranged with said light hole and the coloured glass portion that is used to reduce logical light quantity that is wholely set with said infrared ray optical filtering portion.
Further, be provided with the installation portion that is used for ccontaining said pair of switching device of optical fiber in the said barrel.
The camera lens module of the utility model is arranged at barrel inside with two switching device of optical fiber, has reduced the tractive force that switching device of optical fiber receives, and can guarantee the normal switching of optical filter; And on cutoff filter, increase coloured glass portion to have reduced light-inletting quantity, solved and advanced the problem that light excessively produces the exposure phenomenon daytime.
Description of drawings
Fig. 1 is the structural representation of the camera lens module of the utility model embodiment.
Fig. 2 is the structural representation of two switching device of optical fiber of the utility model embodiment.
Embodiment
The camera lens module that sees figures.1.and.2 to the utility model embodiment describes.
The camera lens module of the utility model as shown in Figure 1 comprises: front end is provided with barrel 1, front lens unit 2, rear lens unit 3 and two switching device of optical fiber 4 of light hole 11.Wherein, front lens unit 2 is positioned at barrel 1 inside with rear lens unit 3 and is oppositely arranged with light hole 11, and two switching device of optical fiber 4 are arranged between front lens unit 2 and the rear lens unit 3.Also be provided with the installation portion 5 that is used for the two switching device of optical fiber 4 of ccontaining installation at barrel 1.
As shown in Figure 2 pair of switching device of optical fiber 4 comprises: be used for the cutoff filter 41 of filtering IR, full spectrum glass filter 42 and switching mechanism 43.Wherein, switching mechanism 43 is connected with external drive circuit, and switching mechanism 43 is used to drive cutoff filter 41 and moves in barrel 1 with full spectrum glass filter 42.When daytime, light was sufficient, external drive circuit drove switching mechanism 43 and then drives cutoff filter 41 itself and light hole 11 are oppositely arranged, and can the IR elimination can be exempted from the image that IR disturbed and then formed real colour; When night during insufficient light, switching mechanism 43 drives full spectrum glass filter 42 is oppositely arranged its and light hole 11, can make full use of all light, has improved low photograph performance greatly, makes the shooting picture clear and natural.
The camera lens module of the utility model is arranged at barrel 11 inside with two switching device of optical fiber 4, has reduced the tractive force that two switching device of optical fiber 4 receive, and can guarantee the normal switching of optical filter.
The above is the embodiment of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also are regarded as the protection domain of the utility model.
Claims (4)
