The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
By Fig. 4 and Fig. 5 as can be known, the coaxial perspective light source 100 of the slab construction that the utility model provides mainly comprises pedestal 101, LGP 102, light emitting source 103 and cover plate 104.
Pedestal 101 is the main body of whole light source, is used for other parts of carrying, and its integral body is flat slab construction, and the position, intermediate portion offers a light hole 101a.This light hole 101a also is used for installing LGP 102 and light emitting source 103 except printing opacity.
For the ease of LGP 102 and light emitting source 103 are installed, light hole 101a adopts counter bore structure in the utility model.But the structure of light hole 101a is not limited to this, as long as its structure can reach above-mentioned functions.
Owing to needing to install light emitting source 103 in the pedestal 101, therefore it need to have well thermal diffusivity.This pedestal 101 adopts aluminium alloy to make in the utility model, and the pedestal 101 that forms had so both had well radiating effect, also had as the required intensity of main element.
For the shape of pedestal 101 with and the shape of upper counterbore 101a, can decide according to the actual requirements.As an example, pedestal 101 is a cube structure in the utility model, the size of neglecting greatly measured object of its pedestal and deciding.Simultaneously, the counterbore 101a on the pedestal 101 also adopts the square structure with pedestal 101 form fit, must be greater than the profile of measured object for counterbore 101a.
Referring to Fig. 6, light emitting source 103 is comprised of LED lamp bar 103a, and LED lamp bar 103a is by some LED(103b) adopt the mode of single-row arrangement or multiple row to be arranged in order to be formed by connecting, and distribute along the inwall of counterbore 101a and to arrange.Can either reach good illuminating effect like this, the usage quantity that reduces again LED reduces cost; Also greatly reduce simultaneously the heat dissipation capacity of light emitting source 103, effectively prolong the service life of LED.
The shape of LGP 102 matches with the counterbore 101a that light emitting source is installed so that counterbore 101a in light emitting source (LED lamp bar 103a) be distributed in LGP 102 around; Simultaneously the thickness of LGP 102 is identical with the degree of depth of counterbore, and thus so that can be just complete being placed among the counterbore 101a of LGP 102, and so that the light of light emitting source (LED lamp bar 103a) generation can enter into LGP 102 from the side.Because the counterbore 101a in the utility model is square, therefore this LGP 102 also is square;
LGP 102 in the utility model can change line source into the performance of area source except possessing general LGP, and it also has spectroscopical effect.For this reason, LGP 102 is comprised of numerous nanometer glass grain, and base-material is acrylic.Thus, after the light that sends of LED entered into LGP 102 from the side all around, the numerous nanometer glass grain in it carried out many times refraction and irregular reference to light, and final light penetrates from the positive and negative of LGP.
The shape of cover plate 104 is corresponding with pedestal 101, offers the loophole 104a corresponding with counterbore 101a on it.By being fixedly connected with pedestal 101, thus LGP 102 is spacing in counterbore 101a.
For cover plate 104 and pedestal 101 are fixed, four angles that offer the surface of counterbore at square pedestal 101 are respectively arranged with screw hole 101b, simultaneously the corresponding through hole 104b that is provided with respectively at 104 4 angles of cover plate.Like this after being placed in LGP 102 among the counterbore 101a, cover plate 104 is covered on the pedestal 101 so that the through hole 104b on it corresponding with screw hole 101b on the pedestal 101 after, be fixed from four angles by screw and get final product, very convenient, also make things convenient for the dismounting in later stage.
Referring to Fig. 7, the coaxial perspective light source that forms according to such scheme 100 its when work, the first step is with camera or camera lens 200, coaxial perspective light source 100 and from top to bottom coaxial placement of testee 300.
Second step, the LED light emitting source 103 of four single-row arrangements in the coaxial perspective light source 100 produces light, and enters into from the side LGP 102 around LGP 102.
In the 3rd step, 102 pairs of these light of LGP are through many times refraction, the irregular reference of nanometer glass grain, and final so that light penetrates from the positive and negative of LGP, form illuminating ray 105 vertically downward.
In the 4th step, illuminating ray 105 is vertically downward according to testee 300.
In the 5th step, testee 300 produces reflection ray 301 upwards, and this reflection ray 301 shines to LGP 102.
The 6th step entered the reflection ray 301 in the LGP 102, and through many times refraction, the irregular reference of nanometer glass grain, finally the positive and negative from LGP penetrates, and shines to camera or camera lens.
In the 7th step, camera is taken pictures or lens imaging.
Above demonstration and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
