Description
Technical field
The utility model relates to a kind of infrared induction Fresnel Lenses, is specially a kind of locate mode infrared induction Fresnel Lenses.
Background technology
Infrared induction Fresnel Lenses is generally the thin slice being noted pressure by highdensity polyolefine material, its surface one side is light face, another side utilizes the imaging of convex lens and the interference of light and refraction principle, and sensitivity as required, receiving angle and distance of reaction etc., design Fresnel section.Infrared induction Fresnel Lenses can focus on and receives in unit entering infrared ray that the people of search coverage or some animal etc. launch, and due to its search coverage light and shade subregion, make the mobile object entering search coverage receive with the form of temperature variation the rpyroelectric infrared signal that unit changes.According to some designing requirement, the section of infrared induction Fresnel Lenses is asymmetric in a direction (X-axis or Y direction), another direction is symmetrical, when even all directions are all asymmetric, locating surface is not set, if carefully do not distinguished when installing and using, when will cause being applied in the aspect such as infrared sensing switch, infrared induction light fixture, there is larger difference in the investigative range of each finished product, causes harmful effect to the consistance of finished product detection performance.
Utility model content
Technical problem to be solved in the utility model is the deficiency in above-mentioned existing design, the lens of same type arrange locating surface, and on locating surface, be provided with at least one positioning area, lens processing is easy, for user provides the location and installation of portable, product reliability is significantly improved.
The utility model is achieved through the following technical solutions: a kind of locate mode infrared induction Fresnel Lenses, and it has locating surface, and described locating surface is provided with at least one positioning area; Described lens section is multi-region multisection type.
Further, described lens-shape has circle, rectangle or other polygonal shape.
Further, described lens section is that axis of symmetry is symmetrical in X-direction with Y-axis, and be that axis of symmetry is symmetrical up and down in Y direction with X-axis, X-direction is not identical with the section of Y direction.
Further, described lens section is all asymmetric in all directions (X-axis and Y direction).
Further, described lens section is symmetrical in X-axis, asymmetric in Y-axis.
Further, described lens section is symmetrical in Y-axis, asymmetric in X-axis.
Further, described lens section is all asymmetric in all directions (X-axis and Y direction).
Further, the positioning area of described rectangular lens is the boss protruding from locating surface.
Further, the positioning area of described round lens is the groove being depressed in locating surface, and described groove is two, and is centrosymmetric.
Further, described lens material is plastics (as tygon).
Compared with prior art, the beneficial effects of the utility model are: be easy to processing, resolution is high, easy to use, are conducive to ensureing the consistance of product detection angle, direction and distance, avoid the generation of leakage action and misoperation.
