Abstract
The utility model discloses an RGB (red green blue) LED light measuring device which comprises a camera, a lamp cover, red LED sources, green LED sources and blue LED sources. The top and bottom of the lamp cover are open. The camera is installed above the lamp cover. Two red LED sources are obliquely installed on the inner side of the upper edge of the lamp cover in longitudinal symmetry. Four green LED sources and four blue LED sources are evenly and vertically installed on the inner side of the lower edge of the lamp cover. The green LED sources are longitudinally parallel with the blue LED sources. The RGB LED light measuring device enables light to irradiate an object to be measured with high brightness and high uniformity, so that measurement accuracy is improved.
Description
Technical field
The utility model relates to a kind of redgreenblue LED optical measurement instrument.
Background technology
Paste solder printing forms irregular thrust at circuit board, for improving product percent of pass, needs to use the LED optical measurement instrument to measure.For improving measurement accuracy, the light uniform irradiation is not advised on the lateral process thing to circuit board.
Yet, determined that by the characteristic of LED lamp it is a lot of that the luminous point brightness of LED center always surpasses peripheral halation brightness.Therefore, adopt the direct projection mode can cause the testee center very poor with the luminance brightness homogeneity of periphery, namely testee center light intensity is big, and the peripheral profile light intensity of testee is little, even be not illuminated, be unfavorable for the gray scale operation that picture extracts, measurement accuracy is not high.
In view of above-mentioned technical matters, the inventor furthers investigate it, develops a kind of redgreenblue LED optical measurement instrument that overcomes above-mentioned technical matters, and this case produces thus.
The utility model content
The purpose of this utility model is to provide a kind of smooth uniform irradiation on testee and improves the redgreenblue LED optical measurement instrument of measurement accuracy.
For reaching above-mentioned purpose, solution of the present utility model is:
A kind of redgreenblue LED optical measurement instrument comprises camera, lampshade, red LED light source, green LED light source and blue led light source; Lampshade upper and lower opening, camera are installed in the lampshade top; Symmetry and be mounted obliquely within inboard, lampshade upper edge before and after two red LED light sources; Four green LED light sources and four blue led light sources evenly and vertically are installed in inboard, lampshade lower edge, and green LED light source and the setting of blue led light source parallel longitudinal.
Further, the green LED light source is positioned on the blue led light source.
Further, receive in the lampshade upper edge and form the dip plane, the red LED light source is installed in the inboard, dip plane, and the dip plane becomes miter angle with Z-axis.
Further, the front end of red LED light source, green LED light source and blue led light source arranges even tabula rasa.
After adopting such scheme, symmetry and be mounted obliquely within inboard, lampshade upper edge before and after two red LED light sources of the utility model, the center luminous point of red LED light source is radiated at outside the testee, and the edge-lit point is radiated on the testee, the edge-lit of two red LED light sources o'clock is radiated on the testee from two different directions, and light shines on the testee equably; And, four green LED light sources and four blue led light sources evenly and vertically are installed in inboard, lampshade lower edge, the center luminous point level of green LED light source and blue led light source is radiated at outside the testee, and the edge-lit point is radiated on the testee, and light shines on the testee equably; Camera collects the even light of the different colours of testee reflection, improves accuracy of measurement.
On the other hand, the red LED light source is installed in the inboard, inclined-plane, and the inclined-plane becomes miter angle with Z-axis, and ruddiness is tilted to down irradiation, and this angular illumination is the most even to the ruddiness on the testee.

Embodiment
Below in conjunction with drawings and the specific embodiments the utility model is described in detail.
Consult Figure 1 and Figure 2, a kind of redgreenblue LED optical measurement instrument that the utility model discloses comprises lampshade 1, camera 2, red LED light source 3, green LED light source 4 and blue led light source 5.
Lampshade 1 upper and lower opening, camera 2 are installed in lampshade 1 top, and camera 2 is used for accepting the light of testee emission.
Two red LED light source 3 front and back symmetry and be mounted obliquely within inboard, lampshade 1 upper edge.In the present embodiment, its mounting means is: receive formation dip plane 11, two red LED light sources 3 in lampshade 1 upper edge and be installed in 11 inboards, dip plane.When the angle a of dip plane and Z-axis was miter angle, the ruddiness that shines on the testee was the most even.
Four green LED light sources 4 and four blue led light sources 5 evenly and vertically are installed in inboard, lampshade 1 lower edge, and green LED light source 4 and the 5 parallel longitudinal settings of blue led light source, i.e. green light and blue light level irradiation in the same way.
In the present embodiment, red LED light source 3 is arranged in the eminence of lampshade 1, and green LED light source 4 and blue led light source 5 are arranged in the lower of lampshade 1, and green LED light source 4 is positioned on the blue led light source 5.Because the wavelength of ruddiness is the longest, penetrability is best, and red LED light source 3 is arranged in eminence, can be used for the irradiation to Mark point (reference point) on the circuit board; Simultaneously, because the wavelength wavelength of green glow and blue light is shorter, penetrability is poor, it is arranged on the lower of lampshade 1, and the wavelength of the wavelength ratio blue light of green glow is big, therefore, green LED light source 4 is positioned on the blue led light source 5, so arrange, make more rays be radiated at the profile of testee, improve illumination brightness and uniformity coefficient.
For further improving the illumination uniformity coefficient, even tabula rasa 6 can be set at the front end of red LED light source 3, green LED light source 4 and blue led light source 5.
When the utility model uses, its at testee be the irregular thrust that paste solder printing forms at circuit board, generally at diameter less than 10mm, height is less than the measurement of not advising the lateral process thing of 1.5mm.As shown in Figure 2, may further comprise the steps during operation: testee 7 places the below of lampshade 1 under shed; Uniform irradiation (non-direct projection) is on testee 7 respectively for red, green, blue three coloured light, and camera 2 absorbs picture to the irradiation of three coloured light respectively; The gray scale operation (gray scale operation of picture is prior art, does not give unnecessary details herein) of the picture by different colours calculates the vertically profiling of testee 7, i.e. the area of testee 7 on circuit board.
The above is preferred embodiment of the present utility model only, is not the restriction to this case design, and all equivalent variations of doing according to the design key of this case all fall into the protection domain of this case.
