Abstract

The utility model discloses a minitype camera with autologous light source, aiming to provide a minitype camera, which is of autologous light source workable under the circumstances of zero illuminance and can completely isolate the ray sent out by the autologous light source from being reflected by a photographed object and entering the lens of the camera. The essential of the technical proposal is that the camera body is a convex-shaped structure. A through hole is arranged in the center of light source. The through hole of the source light is coupled on the convex-shaped camera and lower than the lens cover of the camera. Thus the ray sent out by the autologous light source can not be irradiated onto the tens glass and reflected into the lens. The utility model is mainly used for photographing under the circumstances of zero illuminance.

Description

The minisize pick-up head of automatic light source

Technical field:

The utility model belongs to a kind of minisize pick-up head, the particularly a kind of automatic light source that can work under zero illumination environment and can isolate light that automatic light source sends enters cam lens without the subject reflection minisize pick-up head fully.

Background technology:

At present, the various miniature video cameras of selling on the market generally all do not have automatic light source, the minisize pick-up head that few part automatic light source is arranged generally all is that light source and cam lens are contained in the same cylinder type shell, the protective treatment of camera lens and light source is done in the front with a slide, reflex to cam lens and this mode can make the light of automatic light source be mapped on the interface of slide, thereby influence the sharpness and the authenticity of camera imaging.Up to the present, on market, do not find both automatic light sources as yet, isolate fully again that light that automatic light source sends be can't help the subject reflection and the minisize pick-up head that enters cam lens.

Summary of the invention:

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple in structure, and automatic light source can absorb minisize pick-up head clear, true picture under the environment of zero illumination.

The utility model comprises lens cap, camera lens, light source body, lens mount, shooting movement, head shell.Form a camera body by lens cap, camera lens, lens mount, shooting movement, head shell,, and just be used on " protruding " shape step of this main body the light source body is installed, and the light source body is lower than lens cap as Fig. 1 with " protruding " font structure.The power supply of light source body links to each other with shooting movement power supply in the lens mount by lens mount with conductor and lead, and shooting core power lead is drawn with monitor from the wire hole of head shell with the core video signal cable of making a video recording and is connected with direct supply.So just can under the environment of zero illumination, can both take the photograph clear, real image by the light illumination that camera carries.

Described light source body is the columnar light source body that there is through hole at the center, but luminescent material light emitting diode, also infrared emission tube.

The beneficial effects of the utility model:

1, light source is positioned at around the camera lens and is lower than camera lens, and therefore more even to the object illumination in camera lens the place ahead, the light of the opposing party's surface light source unit can not directly be mapped on glass the reflexing in the camera lens of lens cap and go, and like this, the image of camera picked-up is more clear, true.

2, owing to adopted light emitting diode to do the light source body, therefore, the camera volume is little, in light weight, light source body power consumptive province, life-span are long.

3, owing to the camera automatic light source, so can under zero illumination environment, normally absorb scene image.

Description of drawings:

Fig. 2 is the structural representation of the camera body of " protruding " font structure, and Fig. 1 is a structural representation of the present utility model.

Embodiment:

Below in conjunction with accompanying drawing the utility model is further described.

In Fig. 1, the minisize pick-up head of automatic light source mainly is made of lens cap 1, camera lens 2, light source body 3, lens mount 5, shooting movement 7, head shell 8 etc.

Cover glass is arranged at the top of described lens cap 1, also can make the light of subject enter camera lens 2 in order to len 2.All the other of lens cap 1 partly are metal material, and light that light source body 3 sends can not directly enter camera lens 2 and lens cap is on glass in order to isolate.Lens cap 1 is connected with lens mount 5 by screw thread.

To be energy change the light signal of camera lens 2 focal imagings the circuit module of vision signal into to described shooting movement 7, and it is screwed on lens mount 5.

When using the utility model product, be connected with lens mount 5 usefulness screw threads by figure camera lens 2, lens cap 1 is connected with lens mount 5 usefulness screw threads, and shooting core 7 is connected with lens mount 5 usefulness screws.Lens mount 5 is connected with head shell 8 usefulness screw threads, more than connect the back and form " protruding " font camera (as Fig. 2), have the center light source body 3 of through hole to be socketed in the minisize pick-up head that just has been combined into an automatic light source on " protruding " font camera top stage then.The positive source of light source body passes and seals back with lead by the aperture 4 on lens mount 5 steps with conductor with negative pole and links to each other with the power positive cathode 6 of shooting movement 7, the power lead of shooting movement 7 and video signal cable are drawn with monitor and direct supply by the wire hole on the head shell 89 and are connected, and the minisize pick-up head of automatic light source is started working.

Claims

1, a kind of minisize pick-up head of automatic light source, comprise lens cap, camera lens, lens mount, shooting movement, head shell, light source body, the camera body that it is characterized in that " protruding " font structure that described lens cap, camera lens, lens mount, shooting movement, head shell constitute, the light source body is installed on the step, described light source body by conductor and lead be connected with power connection again after the shooting movement is connected, described power connection is connected with direct supply.

2, the minisize pick-up head of automatic light source according to claim 1 is characterized in that described light source body is that a plurality of light emitting diodes are formed.

3, the minisize pick-up head of automatic light source according to claim 1 is characterized in that described light source body is that a plurality of infrared transmitting tubes are formed.

4,, it is characterized in that there is a through hole at described light source body center according to the minisize pick-up head of claim 2 or 3 described automatic light sources.
