Description
Technical field
The utility model belongs to lighting device technical field, is specifically related to high uniform rectilinear illumination light-source system.
Background technology
At present, in field of machine vision, due to the high-resolution of line scan camera, the feature of Large visual angle, makes this camera applications more and more extensive.Therefore, produce corresponding linear light source and also more and more come into one's own, the quality of linear light source, can the situation of contrast directly on response diagram picture.Linear light source the earliest, use be all linear optical fiber, and linear optical fiber not only price, easily damages, and needs to coordinate lighting source (major part all uses the lighting source of bulb type) together to use, and not only additionally increases expense, and takes up space very much.Afterwards in order to the shooting angle of linear optical fiber can be regulated, add cylindrical lens, but cylindrical lens processing is somewhat expensive, frangible, and often changes an angle and all need die sinking again, uneconomical.
Utility model content
For prior art Problems existing, the purpose of this utility model is to design the technical scheme providing high uniform rectilinear illumination LED light source system.
Described high uniform rectilinear illumination light-source system, it is characterized in that comprising high uniform rectilinear illumination light source, imaging lens and CCD, described high uniform rectilinear illumination light source comprises light source fixed housing and is arranged on the LED in light source fixed housing, circuit board is equipped with bottom described LED, heat sink is equipped with bottom described circuit board, bottom described heat sink, laminating arranges fan, described LED top is equipped with light-emitting plate, what in described light-emitting plate, setting was corresponding with LED goes out light slit, the described width going out light slit expands gradually by outgoing light direction, the described side going out light slit is provided with reflecting layer.
Described high uniform rectilinear illumination light-source system, is characterized in that the light source fixed head III that described light source fixed housing comprises light source fixed head I, light source fixed head II and is arranged between light source fixed head I, light source fixed head II.
Described high uniform rectilinear illumination light-source system, is characterized in that the described angle of inclination, two sides going out light slit is 12 °.
Above-mentioned high uniform rectilinear illumination light-source system structure is simple, reasonable in design, reasonably arranged by LED and light-emitting plate, emergent light is made to be irradiated on testee uniformly, the linear optical fiber and cylindrical lens that use at present can be replaced, not only use cost is low, and light-emitting plate is processed and changes all very convenient, give on using and bring great convenience, optical fiber and the same effect of cylindrical lens can be reached, be provided with independently cooling mechanism in high uniform rectilinear illumination light source in addition, its inner heat produced can be discharged in time, extend service life.

Detailed description of the invention
The utility model is further illustrated below in conjunction with Figure of description.
As shown in Figure 1, high uniform rectilinear illumination light-source system comprises high uniform rectilinear illumination light source 1, imaging lens 3 and CCD4, and wherein imaging lens 3 and CCD4 are that straight line is arranged, light supply apparatus A and arranging in 45 degree between imaging lens 3 and CCD4.
As shown in Figures 2 and 3, high uniform rectilinear illumination light source 1 comprises light source fixed housing, the light source fixed head III 103 that light source fixed housing specifically comprises light source fixed head I 101, light source fixed head II 102 and is arranged between light source fixed head I 101, light source fixed head II 102.Be provided with LED 108 in light source fixed housing, be equipped with circuit board 105 bottom LED 108, be equipped with heat sink 106 bottom circuit board 105, bottom heat sink 106, laminating arranges fan 107, ensures effectively to dispel the heat.Circuit board 105 and fan 107 connecting power line 110.LED 108 top is equipped with light-emitting plate 104, and what in light-emitting plate 104, setting was corresponding with LED 108 goes out light slit 109, and the width going out light slit 109 expands gradually by outgoing light direction, and the side going out light slit 109 is provided with reflecting layer.The preferred structure going out light slit 109 extends out by 12 ° of inclinations for its two sides, forms horn-likely to extend out structure, and the light of such outgoing just can be irradiated on testee uniformly.
During work, the light source of high uniform rectilinear illumination light source 1 outgoing, incides on measured object 2, and measured object 2, after irradiating uniformly, produces diffuse reflection, is converged be imaged onto on the target surface of CCD4 by imaging lens 3.
Below be only described with regard to the utility model preferred embodiment, but can not be interpreted as it is limitations on claims.The utility model is not only confined to above embodiment, and its concrete structure allows to change.All various changes done in the protection domain of the utility model independent claims are all in protection domain of the present utility model.
