Abstract
The utility model discloses a light source without glint for shooting, which comprises a light holder, an annular light source and a diaphragm. Operation principle of the utility model is as follows: After the light emitted by the annular light source is shaded by the black diaphragm, no light will be cast onto objects to be shot and directly reflected to lens. In addition, the light obliquely cast onto objects as above is reflected out of lens. Therefore, only scattered light (diffuse reflection light) can enter into the lens to form clear image. The diaphragm matches the external thread on the external surface of the light holder through the internal thread to realize up-and-down light transmittance adjustment and clearer images of objects as above. The utility model can quite completely eliminate unclear images arising from current annular light source for shooting.
Description
Technical field
The utility model relates to a kind of light source, especially a kind of no-reflection light source for shooting.
Background technology
When " indicating gauge " series products is carried out Measuring and testing, usually to use automatic calibrating instrument, instrumentations such as image measurer, in order to make the gamma camera of automatic calibrating instrument or image measurer, camera obtains detected material (as pointer dial gauge, clock gauge, lever meter, inside meter, indicating gauges such as tensimeter) sharp image, when taking, existing common way is a direct annular lighting source of installation in the front of camera lens, taking lens is positioned on the center line of annular light source, and commonly used annular light source is as circline, the annular LED lamp, face matrix LED lamp etc.Strong reflective spot when these light sources are not considered maybe can't avoid taking, the light that sends that its essence is annular light source can enter taking lens to a certain position reflection of image surface taking, the body surface image that makes this position is by the serious covering of the strong luminescence spot (or face) of light source, thereby form dried scratching, can not obtain the sharp image of detected material (as indicating gauge), influence testing result.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of no-reflection light source for shooting is provided.The utility model mainly is made up of lamp socket, annular light source, shading light hurdle three parts.Described lamp socket is that the lamp socket tail pipe is arranged behind the lamp socket circle, and the endoporus of lamp socket tail pipe can insert gamma camera or camera lens, on the lamp socket circle annular light source is installed, and the hole that can pass the annular light source power lead is arranged, and the outside surface of lamp socket circle is provided with external thread; Described shading light hurdle is the circular lid-like that light hole is arranged at the bottom, and its inwall is a black, and inwall is provided with internal thread and matches with lamp socket circle outside surface external thread, and outer wall is provided with anti-skidding line; The light that the width on shading hurdle, bottom just in time can block annular light source can vertical irradiation to the subject surface.
The novel principle of work of this reality is: after the light that annular light source sends is blocked by black shading light hurdle, do not have irradiate light and arrive the subject surface and direct reflected back camera lens, oblique fire then is reflected to outside the camera lens to the light on subject surface, have only scattered light (promptly diffusing) thus can inject camera lens forms sharp image.Shading light hurdle can match with lamp socket circle outside surface external thread by its inwall internal thread, realizes moving up and down regulating light transmission capacity, to obtain subject image more clearly.
The novel beneficial effect of this reality is: 1, solved existing annular light source for shooting more up hill and dale and caused the visual unsharp problem of taking; 2, when the measurement instrument that uses the camera shooting type automatic detection instrument that pointer dial gauge, clock gauge, lever meter, inside meter, tensimeter etc. are had a circular glass lid detects, particularly to having the table class of convex glass lid, this new type light source has solved illumination and reflective contradiction well, has very high practical value; 3, simple in structure, cost is low, easy popularization.
