Limitation.
The light compensating apparatus of an embodiment of the present invention includes light compensating lamp 2 and the beam projecting that the light compensating lamp 2 is arranged in
Microstructure film 3 on direction, the microstructure film 3 carry out deviation to the light that the light compensating lamp 2 is emitted.
The light compensating apparatus of the utility model carries out deviation to the light that light compensating lamp is emitted using microstructure film, thus, it is possible to
The adjusting to light filling is realized in the space of very little, to save space；In addition, deviation light can solve to a certain extent
The light-blocking problem of structural member, the light for making full use of light compensating lamp to issue.
The light compensating apparatus of the utility model can be used for infrared and visible light light filling light distribution.Preferably, the light compensating lamp 2
For infrared lamp.
The commonly used optical device in security monitoring video camera light filling, with lens, based on reflector.Some structure sizes compared with
It also needs to reserve certain space to light filling device in small type, and optical device size must compress to obtain very little, this is just
Optical property is resulted in also to weaken therewith.Often there is the problems such as section light, light-blocking.In addition, there are also some types to use infrared transparent cover
Texture processing homogenizes light using frosted glass, but the processing of this kind of texture or frosted glass, be all by electric discharge or
Person's chemical attack forms some gully textures on surface, and this lines is generally chiefly used in appearance effect, in even light and astigmatism
Meanwhile transmitance is also sacrificed significantly, and light-dispersing effect is also than relatively limited.What electric discharge or chemical attack were formed is irregular ditch
Gully
Microstructure film is a kind of optical thin film, and certain micro structure array is formed on the transparent membranes such as plastic foil, when
When light penetrates these micro-structures, corresponding deviation can occur because of the characteristic of micro-structure, to change original direction of propagation.
Microstructure film is usually to utilize the techniques such as photoetching in the microgroove of surface formation rule, and the shape according to different demands microgroove is poor
It is different.For example, in one embodiment, the lines as microstructure film has similar shutter.
Light portion 31 and gluing portion 32 can be identical structure, that is to say, that all have micro-structure.Advantageously, only
Micro-structure is had in side.Transmittance section 31 and gluing portion 32 can be different structure, that is to say, that gluing portion 32 without
Micro-structure.Gluing portion 32 is pasted by double-sided adhesive to light cover structural member.The gluing portion of microstructure film 3 can be first arranged in double-sided adhesive
32, can also first it be arranged on light cover structural member 4.
Advantageously, micro-structure only is arranged in the side of microstructure film.But all it is arranged in the two sides of microstructure film micro-
The embodiment of structure is also included within the protection scope of the utility model.In the two sides of microstructure film, micro-structure is all set
In the case of, it is advantageous to micro-structure is not provided in gluing portion.
By test, for being normally applied occasion, sticking double faced adhesive tape intensity can satisfy reliability requirement substantially, but right
In some project situations relatively high for protection level requirements, video camera often works in higher temperature and is easier to receive
Concussion, mucilage glue surface can be punched and be fixed by screws on structural member.
Specifically, in order to which the fix tightly for improving microstructure film is fixed, in another embodiment, the microstructure film 3 is same
When be fixed on light cover structural member 4 by double-sided adhesive and threaded connector.For example, in the embodiment shown in Figure 2, in each glue
One screw is separately set simultaneously at viscous portion to fix microstructure film.
Light cover structural member 4 is preferably plane for the surface of microstructure film 3 to be arranged, or curved surface.Either that
Kind situation, the microstructure film 3 must be all fitted tightly on the surface of the light cover structural member 4.For example, in Fig. 4,
The surface for microstructure film 3 to be arranged of light cover structural member 4 is curved surface.Such structure can better adapt to the outer of video camera
It sees, still, there is higher requirement for the fixation of microstructure film.Advantageously, in light cover structural member 4 for micro- knot to be arranged
In the case that the surface of structure film 3 is curved surface, microstructure film 3 has the shape being adapted with the curved surface.
In order to which the thickness with good stickiness, microstructure film 3 is preferably provided in the range of 0.1mm to 0.4mm.It is logical
Often, microstructure film 3 has certain flexibility.
Due to the limited area of microstructure film 3, in order to more efficiently meet the needs of deviation light, the angle of infrared lamp is not
It preferably uses excessive.After tested and comparative analysis, it is preferable that 30% light intensity angle of the light compensating lamp 2 is in the range of 30-50 degree.
If angle is bigger than normal, there will be a large amount of light not pass through polarisation microstructure film deviation, using effect is decreased obviously.In addition, hair
Bright people's discovery, deviation effect are also influenced by light angle, and infrared lamp angle is bigger, and the deviation effect on wide-angle direction is poorer.
Light cover structural member is usually die casting, and surface sprays black.Mainly fixed lens component, infrared light board and infrared
The effect of transparent cover or microstructure film.But the utility model is without being limited thereto, light cover structural member can also be using other design sides
Formula.
The utility model also provides a kind of video camera, and the video camera includes light compensating apparatus as described above.In Fig. 1 and figure
In 4 illustrated embodiments, the video camera is dome type camera.It is symmetrically set in the left and right sides of the camera lens 1 of the dome type camera
Be equipped with aforementioned light compensating apparatus, the light for being emitted corresponding light compensating lamp 2 positioned at the microstructure film 3 of the light compensating apparatus in the left side of camera lens 1 to
Left avertence folding, the light for being emitted corresponding light compensating lamp 2 positioned at the microstructure film 3 of the light compensating apparatus on the right side of camera lens 1 deviation to the right.
The shape of microstructure film 3 can according to need setting.Preferably, the shape of the microstructure film 3 is and 1 knot of camera lens
The identical circle ring sector shape of structure.Microstructure film shape is the circle ring sector shape for saving spatial design to coincide with lens construction
Shape, because having transparent ball cover (eliminating transparent ball cover in Fig. 1) outside video camera, therefore thin-film width is unsuitable wide, to avoid with ball
Cover interference.For example, the width (semidiameter of Inner arc and external arc) of microstructure film is designed as 7.2mm.
In addition, the structure using above-mentioned circular arc can also guarantee fool proof in certain degree, can compare during installation
It is assembled easily.
The utility model has innovatively used the plastic film with micro-structure on dome type camera, can be by by light
Two sides deviation avoids the light-blocking of lens construction to beam to the left and right, improves the night vision effect of infrared light filling.
Finally it is noted that above embodiments are only to illustrate the technical solution of the utility model, rather than it is limited
System.Those skilled in the art should understand that: it is possible to modify the technical solutions described in the foregoing embodiments, or
Person's equivalent replacement of some of the technical features；These are modified or replaceed, and do not make the essence of corresponding technical solution de-
Spirit and scope from various embodiments of the utility model technical solution.
