Abstract
The utility model discloses an infrared ray camera lens device, which comprises an outer casing, a light transmitting lens, a camera lens, an infrared lamp, and a sleeve mat. The infrared lamp is uniformly distributed outside the sleeve mat, and the camera lens is extended into the inner cavity of the sleeve mat. The infrared ray camera lens device is characterized in that a ring groove is arranged on the light transmitting lens, and the outer end of the sleeve mat is embedded into the ring groove. The ring groove is provided with a groove bottom, the sleeve mat is a black sleeve mat and provided with preset wall thickness which ensures that the infrared ray emitted by the infrared lamp adjacent to the sleeve mat passes through the reflection ray which is reflected by the light transmitting lens to generate blockout. By adopting the utility model, the disturbance to the shot of the camera lens by the infrared reflection ray can be reduced, thus, after the infrared lamp is turned on, a circle of white light or white smog condition is avoided to be displayed on the display screen of the video camera, and the image quality of the video camera is effectively improved.
Description
Technical field
The utility model relates to infrared pick-up device field, is a kind of technology of infrared pick-up lens assembly specifically.
Background technology
In today of high speed development, camera head has become the converter tools in people's life, as digital camera, video camera, also is used as monitoring in some occasion.Because dim light can not satisfy the shooting light requirement of camera head, therefore be equipped with infrared lamp night before pick-up lens, satisfy the shooting requirement by infrared ray.Nowadays adopt the flat glass eyeglass on the market usually; black foam sleeve gasket is compressed; stop that infrared lamp light directly is mapped in the camera lens; as shown in Figure 4; there is following shortcoming in such imaging lens device: because glass mirror has thicker thickness; there are suitable distance in the end face of black foam sleeve gasket and the lateral surface of glass mirror; behind Infrared process glass mirror; still the Infrared of some directly enters in the camera lens at the outer side surface generation reflection ray 42 of glass mirror; therefore after opening infrared lamp; on the display screen of video camera, a circle white light occurs or become the state of a white mist, thereby reduced the quality of camera picture through regular meeting.
Summary of the invention
The purpose of this utility model provides a kind of interference that reduces infrared external reflection light to the pick-up lens shooting, effectively improves the infrared pick-up lens assembly of camera photography image quality.
The purpose of this utility model is achieved through the following technical solutions.
A kind of infrared pick-up lens assembly, comprise shell, transmission lens, pick-up lens, infrared lamp, sleeve pad, infrared lamp is distributed in the outside of sleeve pad, and pick-up lens stretches into the inner chamber of sleeve pad, it is characterized in that: described transmission lens is provided with annular groove, and the outer end of sleeve pad embeds in the annular groove.
Described annular groove is provided with bottom land and described sleeve pad is black sleeve pad and is provided with the predetermined wall thickness that makes the reflection ray generation blocking-up of Infrared after the transmission lens reflection of launching near the infrared lamp of sleeve pad.
Described black sleeve pad is a foam black sleeve pad.
Described annular groove is for running through groove, and the inside and outside wall of the outer end of sleeve pad is provided with step, and transmission lens contacts fixing with step surface.
Be provided with uniform connection rib between the transmission lens inside and outside the described groove.
Compared with prior art have the following advantages:
Owing on transmission lens, be provided with annular groove, the outer end of sleeve pad embeds in the annular groove, promptly be to have reduced the distance of the end face of sleeve pad to the lateral surface of transmission lens, the increase infrared lamp is the distance of reflecting surface to the lateral surface of transmission lens, thereby reduced infrared ray produces reflection ray on transmission lens quantity, therefore the reflection ray that enters into sleeve pad inner chamber significantly reduces, so reduced the interference of infrared external reflection light to the pick-up lens shooting, has improved the camera photography image quality effectively.Particularly when the wall thickness that increases the sleeve pad, a part of reflection ray also can further have been reduced the interference of infrared external reflection light to the pick-up lens shooting by the blocking-up of the jacket wall of sleeve pad, has more effectively improved the camera photography image quality.
When annular groove when running through groove, do not had infrared external reflection light this moment, stopped the interference of infrared external reflection light to the pick-up lens shooting fully, can further improve the camera photography image quality.
Description of drawings
Fig. 1 is the front view of the embodiment of the utility model infrared pick-up lens assembly;
Fig. 2 is the structural representation of the transmission lens among Fig. 1;
Fig. 3 is the side direction cross-sectional view of the embodiment of the utility model infrared pick-up lens assembly;
Fig. 4 is a prior art side direction diagrammatic cross-section.
Embodiment
Be described further below in conjunction with the embodiment of accompanying drawing the utility model infrared pick-up lens assembly.
As shown in Figure 1-Figure 3, the infrared pick-up lens assembly, comprise shell 1, transmission lens 2, pick-up lens 3, infrared lamp 4, sleeve pad 5, infrared lamp 4 is distributed in the outside of sleeve pad 5, pick-up lens 3 stretches into the inner chamber of sleeve pad 5, sleeve pad 5 is foam black sleeve pad or other hard sleeve pad, and color can also be grey or other color, and transmission lens 2 is glass transmission lens or transparent glass lens.Transmission lens 2 is provided with annular groove 21, and the outer end of sleeve pad 5 embeds in the annular groove 21.Annular groove 21 is provided with bottom land 22, and the wall thickness of sleeve pad 5 is thicker, is enough to make the most of reflection ray 42 generation blocking-up of Infrared 41 after transmission lens 2 reflections near infrared lamp 4 emissions of sleeve pad 5.The wall thickness thickening of sleeve pad 5, can do bottom land 22 thin, increase infrared lamp 4 is the distance of reflecting surface to the lateral surface of transmission lens 2, thereby reduced infrared ray produces reflection ray 42 on transmission lens 2 quantity, therefore the reflection ray 42 that enters into the inner chamber of sleeve pad 5 significantly reduces, so reduced of the interference of infrared external reflection light, also be equivalent to increase simultaneously the intensity of bottom land 22 to the pick-up lens shooting.Certainly annular groove 21 can also be made and run through groove, at this moment, transmission lens 2 has been divided into two parts, in order to have installed and fixed transmission lens, on the inside and outside wall of the outer end of sleeve pad 5, be provided with step, two parts transmission lens utilizes step surface contact, but the transmission lens close-fitting of interior part at the inner chamber of sleeve pad 5, the transmission lens of outer part is fixing in the usual way.A kind of mode in addition is to be provided with many uniform connection ribs between the transmission lens inside and outside the groove, connects between the rib to have through hole, the projection of corresponding number is set, projection and through hole close-fitting in the outer end of sleeve pad 5.
Foregoing description is an embodiment of the present utility model, various not illustrating is construed as limiting flesh and blood of the present utility model, the person of an ordinary skill in the technical field can make amendment or is out of shape after having read instructions it, and does not deviate from essence of the present utility model and scope.
