Description
Technical field
The utility model relates to NI Vision Builder for Automated Inspection field, is specifically related to a kind of NI Vision Builder for Automated Inspection lighting source.
Background technology
along with development and the progress of related key technical, machine vision becomes a link very important in industrial automation technology day by day.Traditional machine vision image recognition and measuring system mainly rely on surround lighting or the subsidiary light source of conventional optical system to throw light on.Lighting quality affects very large on the identification degree of system and certainty of measurement, often because lighting quality is not high in measurement, the accuracy that visual pattern is measured reduces, and brings very big error to measurement result.
Rapidly, along with improving constantly of luminance and efficiency, LED has become a kind of lighting engineering of key, compares and is widely used in NI Vision Builder for Automated Inspection in LED technology development.Secondly, in actual applications, light emitting diode is along with the change of PN junction temperature, and the skew of more than 10nm can occur the wavelength exporting light.This gamut not only can affect the color dot of this color, also can have influence on the white point of whole system.Therefore, in order to fundamentally solve the problem of gamut in traditional application, LED must with lower Power operation, or ensureing the high heat endurance of lighting device, this point also limit the application of light emitting diode in NI Vision Builder for Automated Inspection high request lighting source of up-to-date high-power, high energy efficiency, small size.Moreover, the light intensity of light source and colourity is used to be all regulated according to the subjective judgement of picture quality by survey crew in current machine vision measuring system, often to be selected the light source of different colours by replica test according to the change of workpiece material, this conventional method not only efficiency is low, the recognition capability of NI Vision Builder for Automated Inspection characteristic model and certainty of measurement are subject to the influence degree of operating personnel's subjective judgement large, and cannot use in real-time online measuring system.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of NI Vision Builder for Automated Inspection lighting source.
For solving the problems of the technologies described above, the utility model provides following technical scheme: a kind of NI Vision Builder for Automated Inspection lighting source, comprise transparency carrier, LED light source and lower transparency carrier, described LED light source is photographed transparency carrier and lower transparency carrier is inner, the inner surface of described upper transparency carrier and lower transparency carrier is equipped with optical film and diffuser, and described diffuser is cross section is triangle, inverted trapezoidal or circle.
On such scheme basis preferably, described diffuser caves in or protrudes from substrate surface.
On such scheme basis preferably, described optical film is reflective membrane, bright enhancement film or diffusion barrier.
On such scheme basis preferably, described upper and lower transparency carrier is flexible transparent substrate or rigid transparent substrate.
The beneficial effect that the utility model compared with prior art has is: by changing the optical texture of upper and lower transparency carrier, thus the light that LED light source is penetrated can part penetrate from upper transparency carrier, and another part can penetrate from lower transparency carrier.Observe the effect simultaneously can seeing two-sided bright dipping at the upper and lower faces of light source like this, whole clearing degree is high, under the state that LED does not light, keeps the aesthetics of lighting outside, can by change optics on substrate reflective/structure of diffusion, realize colorful picture.
Accompanying drawing explanation
Fig. 1 is the utility model overall structure schematic diagram.
Number in the figure is: the upper transparency carrier of 1-, transparency carrier under 2-, 3-diffuser, 4-LED light source, 5-optical film.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
In description of the present utility model, it will be appreciated that, term " longitudinal direction ", " transverse direction ", " on ", D score, " front ", " afterwards ", " left side ", " right side ", " vertically ", " level ", " top ", " end ", " interior ", orientation or the position relationship of the instruction such as " outward " are based on orientation shown in the drawings or position relationship, it is only the utility model for convenience of description, instead of indicate or imply that the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.
Known with reference to Fig. 1, a kind of NI Vision Builder for Automated Inspection lighting source, comprise transparency carrier 1, LED light source 4 and lower transparency carrier 2, described LED light source 4 is located at transparency carrier 1 and lower transparency carrier 2 is inner, the inner surface of described upper transparency carrier 1 and lower transparency carrier 2 is equipped with optical film 5 and diffuser 3, and described diffuser 3 is cross sections is triangle, inverted trapezoidal or circle.
It should be noted that described diffuser 3 caves in or protrudes from transparent 1 and lower transparency carrier 2 surface, described optical film 5 is reflective membrane, bright enhancement film or diffusion barrier, and described upper and lower transparency carrier 2 is flexible transparent substrate or rigid transparent substrate.
Based on above-mentioned, by changing the optical texture of upper and lower transparency carrier, thus the light that LED light source 4 is penetrated can part penetrate from upper transparency carrier 1, and another part can penetrate from lower transparency carrier 2.Observe the effect simultaneously can seeing two-sided bright dipping at the upper and lower faces of light source like this, whole clearing degree is high, under the state that LED does not light, keeps the aesthetics of lighting outside, can by change optics on substrate reflective/structure of diffusion, realize colorful picture.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
