Abstract
A kind of infrared light diffusion shell, it is covered at least one diffusion shell outside the infrared lamp, the diffusion shell includes cover body and the cover, there is reflecting surface on the cover body, there is direct projection face, the reflection face ring to be located at around the infrared lamp, the direct projection face is set to the front end of the infrared lamp in the cover, the infrared light that the infrared lamp is sent out is incident from the reflecting surface and is reflected to the direct projection face, is projected from the direct projection face.The utility model, with low cost and simply installed mode, improves the light of infrared lamp actual transmission, increases night vision effective area by using optical reflection principle in the case where not increasing infrared lamp power additionally or package assembly does not make big change.
Description
Technical field
The utility model is related to a kind of infrared light diffusion shells, are suitable for law-enforcing recorder and logging instrument.
Background technology
Currently, law-enforcing recorder or logging instrument on the market be all in night use by open it is red come supplement light
Line, and reach certain night visual range and effective area.Because law-enforcing recorder or logging instrument using must waterproof and
It is dust-proof, so in the waterproof or dust-proof glass or Asia gram that are typically provided layer of transparent under surface of shell a certain distance
Power eyeglass, when resulting in infrared lamp to open in this way, the utilization rate of light is greatly reduced, when infrared light can not be designed according to itself
Irradiating angle reach due effective area playing, when in use, monitor can only see on machine a periphery it is dark, in
Between bright circular visual area.Traditional infrared lamp improve light utilization rate method generally using inner arc or outer arc leaded light come
Refracted light, and install fixed point by increase and be mounted on infrared lamp, reduces production efficiency, or increases glass system
Lens are mounted on infrared lamp, and cost is higher.
Utility model content
To solve the above problems, the utility model is intended to provide, a kind of low cost, installation is simple, light diffusion is wide, can increase
The infrared light diffusion shell of big night vision effective area.
To achieve the goals above, the technical solution adopted by the present invention is：A kind of infrared light diffusion shell, including instrument master
Body and the infrared lamp being arranged in the apparatus subject, the infrared lamp are covered at least one diffusion shell, the diffusion shell outside
Including cover body and the cover, there is reflecting surface on the cover body, there is direct projection face, the reflection face ring to be located at described in the cover
Around infrared lamp, the direct projection face is set to the front end of the infrared lamp, and the infrared light that the infrared lamp is sent out is from described anti-
It penetrates face incidence and is reflected to the direct projection face, projected from the direct projection face.
Further, the top and bottom of the cover are plane.
Further, the diffusion shell is transparent plastics PC materials.
Further, 0 °~45 ° of the light angle range for being incident on direct projection face, the light for being incident on reflecting surface
Angular range is 45 °~90 °.
Further, at least one infrared lamp is equipped in the diffusion shell.
Further, the cover body is annular shape, and annular edge has at least two notches, the diameter of the cover body small
In the diameter of the infrared lamp.
Compared with prior art, the beneficial effects of the utility model are：By using optical reflection principle, do not increasing additionally
In the case that infrared lamp power or package assembly do not make big change, with low cost and simply installed mode, improve infrared
The light of lamp actual transmission increases night vision effective area.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the installation sectional view of the utility model.
Specific implementation mode
The technical issues of in order to keep the utility model solved, technical solution and advantageous effect are more clearly understood, below
In conjunction with the embodiments, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only
To explain the utility model, it is not used to limit the utility model.
It should be understood that the orientation or positional relationship of the instructions such as term "left", "right" in the description of the present invention,
To be based on the orientation or positional relationship shown in the drawings, it is merely for convenience of description the utility model, rather than requires this practicality new
Type must be with specific azimuth configuration and operation, therefore should not be understood as limiting the present invention.
As depicted in figs. 1 and 2, a kind of infrared light diffusion shell, including apparatus subject 1 and be arranged in apparatus subject it is red
Outer lamp 2, infrared lamp 2 are covered at least one diffusion shell 3 outside, and diffusion shell 3 includes cover body 31 and the cover 32, is had on cover body 31 anti-
Face 4 is penetrated, in the cover 32 there is direct projection face 5,4 ring of reflecting surface to be located at around infrared lamp 2, before direct projection face 5 is set to infrared lamp 2
End, the infrared light 21 that infrared lamp 2 is sent out is incident from reflecting surface 4 and is reflected to direct projection face 5, is projected from direct projection face 5.Diffusion shell
3 be transparent plastics PC materials.It is equipped at least one infrared lamp 2 in diffusion shell 3, in the present embodiment, is equipped in a diffusion shell 3
The top and bottom of one infrared lamp 2, the cover 32 are plane.
Specifically, 0 °~45 ° of the light angle range in the direct projection face of being incident on 5, is incident on the light angle range of reflecting surface 4
It is 45 °~90 °.Cover body 31 is annular shape, and there are annular edge at least two notches 6, the diameter of cover body 31 to be less than infrared lamp 2
Diameter.In the present embodiment, there are three notches 6 for annular edge tool.
The utility model installation is simple, is molded, can be produced in batches by plastic mould, at low cost, and without changing
Original mounting means after installation is complete in all components, then is packed into from outside by infrared diffusion shell, is directly located at infrared lamp
Above, the acrylic shell of water proof and dust proof is finally refilled.
In use, when hot outer unlatching, after encountering diffusion shell light refraction, the light of refraction can occur for the light that is shot out
Line is refracted to direct projection face, then projects Instrument shell, expands visual range.When without diffusion shell, light, which encounters shell, to be reflected into
Astigmatism, and these astigmatism can not be utilized effectively, form the picture that surrounding is dark, centre is bright.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, therefore, as long as fortune
All any modification, equivalent and improvement etc., should be included in this practicality made by the utility model the description and the appended drawings content
Within novel protection domain.
