Background technology
In multiple Machine Vision Detection occasion checkout gear based on optics, for same spline structure, the workpiece of same size, because the difference of color, and need to adopt light sources of different colors to detect.Most of light sources of prior art cannot change because color is single fixing at present, therefore when detecting the workpiece of different colours, throw light on regard to the corresponding replacing light sources of different colors of needs, therefore, equipment is operated, adjusts cumbersome, and accuracy of detection is not accurate enough.
Summary of the invention
The purpose of this utility model provides a kind of many colors led light source of detecting of being used to, and this light source adopts the LED of RGB three colors to form.Regulate the brightness of LED modules with different colors respectively by adjusting voltage, thereby change the shared ratio of each light source, modulate the light source of required color.It can be in multiple Machine Vision Detection occasion flexible Application, and for can relevant lens providing the coaxial illumination mode, having solved prior art needs corresponding replacing light sources of different colors to detect, and equipment is operated, adjustment is cumbersome, the problem that accuracy of detection is not accurate enough.
The technical scheme that the utility model adopted is, a kind of many colors led light source of detecting of being used to, comprise the circuit of light sources plate, the circuit of light sources plate is provided with three color LED of red, green, blue, three color LED front correspondences three spectroscopes are set, also are respectively equipped with three reflective mirrors three spectroscope fronts, it is in one line to link to each other about spectroscope, end in spectroscope group in one line is provided with one group of condenser, is provided with a reflective mirror at the other end of spectroscope group.
The coaxial led light source of many colors that the utility model is used to detect, its feature also be,
The LED of three colors of described red, green, blue can be the single great power LED of three kinds of colors, also can be the led array of three kinds of colors.
Described led array can be the array that three kinds of LED modules with different colors constitute, and also can be a kind of array of LED formation of color.
Described spectroscope group can be made up of two or more spectroscopes.
The utility model adopts the LED of three kinds of colors to form, and regulates the brightness of LED modules with different colors respectively by adjusting voltage, thereby changes the shared ratio of each light source, modulates the light source of required color.This light source volume is little, easy for installation, can make up arbitrarily by many LED, in multiple Machine Vision Detection occasion flexible Application, and for can relevant lens providing the coaxial illumination mode, having solved prior art needs corresponding replacing light sources of different colors to detect, and equipment is operated, adjustment is cumbersome, the problem that accuracy of detection is not accurate enough.
Description of drawings
Accompanying drawing is the coaxial led light source structural representation of many colors that is used to detect;
Among the figure, 1. circuit of light sources plate, 2. red LED, 3. green LED, 4. blue led, 5. spectroscope, 6. spectroscope, 7. spectroscope, 8. reflective mirror, 9. reflective mirror, 10. reflective mirror, 11. condensers, 12. speculums.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
The utility model as shown in drawings, comprise circuit of light sources plate 1, circuit of light sources plate 1 is provided with three color LED2 of red, green, blue, 3,4, in three color LED2,3,4 front correspondences three spectroscopes 5,6,7 are set, also be respectively equipped with three reflective mirrors 8,9,10 three spectroscope fronts, it is in one line to link to each other about spectroscope, is provided with one group of condenser 11 at an end of spectroscope group in one line, is provided with a reflective mirror 12 at the other end of spectroscope group.
The LED2,3,4 of three colors of red, green, blue among the figure can be the single great power LED of three kinds of colors, also can be the led array of three kinds of colors.Led array can be the array that three kinds of LED modules with different colors constitute, and also can be a kind of array of LED formation of color.
Spectroscope group of the present utility model can be made up of two or more spectroscopes.
The coaxial led light source of many colors that the utility model is used to detect in use, light that the LED2 light source sends is through behind the spectroscope 5, half reflexes to condenser 11, second half is through speculum 8, after speculum 12 grades repeatedly reflect, a loss part, most of light still can arrive condenser 11.In like manner, the light major part sent of light source 3 and light source 4 can arrive condenser 11.Because LED light is additive, mechanism according to the relevant colors addition, regulate the brightness of LED modules with different colors respectively by adjusting voltage, thereby change the shared ratio of each light source, modulate the light source of required color, through repeatedly reflection, just can the part of different colours be detected by condenser 11, because all light all is to penetrate through condenser 11, the utility model can provide the coaxial illumination mode for relevant lens, therefore just can cross very flexibly in multiple Machine Vision Detection occasion to be applied.
Led light source of the present utility model and spectroscope and reflective mirror are one to one, and its structure is not limited to form shown in the accompanying drawing, and therefore, the institute within the scope of claim changes, revises or replaces, and all belongs to the claimed scope of the utility model.
