Description
Technical field
The present invention relates to a kind of redgreenblue LED light measurement apparatus.
Background technology
Paste solder printing forms irregular thrust on circuit boards, to improve product qualification rate, it is necessary to be measured using LED light
Device is measured.To improve measurement accuracy, it usually needs light uniform irradiation is not advised on lateral process thing to circuit board.
However, being determined by the characteristic of LED, it is many that the brightness of LED center luminous point always exceedes periphery halation brightness.Cause
This, can cause the brightness uniformity on testee center and periphery very poor, i.e. testee central light strength using direct manner
Degree is big, and the peripheral profile luminous intensity of testee is small, or even is not illuminated, and is unfavorable for the gray scale operation of picture extraction, measurement
Accuracy is not high.
In view of above-mentioned technical problem, the present inventor furthers investigate to it, develop and a kind of overcome the red of above-mentioned technical problem
Thus turquoise tricolor LED light measurement apparatus, this case produces.
The content of the invention
The red green of measurement accuracy is improved on testee it is an object of the invention to provide a kind of smooth uniform irradiation
Blue tricolor LED light measurement apparatus.
To reach above-mentioned purpose, solution of the invention is：
A kind of redgreenblue LED light measurement apparatus, including camera, lampshade, red LED light source, green LED light source and indigo plant
Color LED/light source；Lampshade upper and lower opening, camera is arranged on above lampshade；It is symmetrical and obliquely install before and after two panels red LED light source
Along inner side on lampshade；Four green LED light sources and four blue led light sources are uniform and be vertically mounted in lampshade lower edge
Side, and green LED light source and the parallel longitudinal setting of blue led light source.
Further, green LED light source is located on blue led light source.
Further, inclined plane is formed along interior receipts on lampshade, red LED light source is arranged on the inside of inclined plane, and inclined plane is with hanging down
D-axis is into 45 degree of angles.
Further, the front end of red LED light source, green LED light source and blue led light source sets uniform light board.
A kind of redgreenblue LED light measuring method, comprises the following steps：
Step one, testee is placed in the lower section of lampshade under shed；
Step 2, red LED light source, green LED light source and blue led light source send red, green, blue three coloured light and equal respectively
Even to be radiated on testee, camera absorbs picture to the irradiation of three coloured light respectively；
Step 3, by the gray scale operation of the picture of different colours, calculates the vertically profiling i.e. measured object of testee
The area of body.
It is symmetrical before and after two panels red LED light source of the present invention and be mounted obliquely within lampshade along interior after such scheme
Side, the center luminous point of red LED light source is radiated at outside testee, and edge-lit point is radiated on testee,
The edge-lit o'clock of two panels red LED light source is radiated on testee from two different directions, is irradiated to uniform light
On testee；Moreover, four green LED light sources and four blue led light sources are uniform and be vertically mounted in lampshade lower edge
The center luminous point horizontal irradiation of side, green LED light source and blue led light source is outside testee, and edge-lit point shines
Penetrate on testee, be irradiated on testee uniform light；Camera collects the different colours of testee reflection
Uniform light, improve accuracy of measurement.
On the other hand, red LED light source is arranged on chamfered inside, and inclined-plane and vertical axis, into 45 degree of angles, feux rouges is tilted towards
Feux rouges in lower irradiation, this angular illumination to testee is most uniform.
Brief description of the drawings
Fig. 1 is front cross-sectional schematic diagram of the present invention；
Fig. 2 is side cross sectional views of the present invention.
Label declaration
The inclined plane 11 of lampshade 1
The red LED light source 3 of camera 2
The blue led light source 5 of green LED light source 4
The testee 7 of uniform light board 6.
Embodiment
The present invention is described in detail below in conjunction with drawings and the specific embodiments.
Refering to shown in Fig. 1 and Fig. 2, a kind of redgreenblue LED light measurement apparatus that the present invention is disclosed, including lampshade 1, phase
Machine 2, red LED light source 3, green LED light source 4 and blue led light source 5.
The upper and lower opening of lampshade 1, camera 2 is arranged on the top of lampshade 1, and camera 2 is used for the light for receiving testee transmitting.
It is symmetrical and be mounted obliquely within lampshade 1 along inner side before and after two panels red LED light source 3.In the present embodiment, it is pacified
Dress mode is：Inclined plane 11 is formed along interior receipts on lampshade 1, two red LED light sources 3 are arranged on the inner side of inclined plane 11.Work as inclined plane
When angle a with vertical axis is 45 degree of angles, the feux rouges being irradiated on testee is most uniform.
Four green LED light sources 4 and four blue led light sources 5 are uniform and be vertically mounted on the inside of the lower edge of lampshade 1, and
Green LED light source 4 and the parallel longitudinal setting of blue led light source 5, i.e. green light and blue light horizontal irradiation in the same direction.
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 is arranged in the lower of lampshade 1, and green LED light source 4 is located on blue led light source 5.Because the wavelength of feux rouges is most long, wear
Permeability preferably, arrange aloft, can be used for Mark points on circuit board by red LED light source 3（Datum mark）Irradiation；Meanwhile,
Because the wavelength wavelength of green glow and blue light is shorter, penetrability is poor, and it is arranged on the lower of lampshade 1, and the wavelength ratio blue light of green glow
Wavelength it is big, therefore, green LED light source 4 is located on blue led light source 5, arranged so that more light are radiated at
The profile of testee, improves illumination brightness and the uniformity.
, can be in red LED light source 3, green LED light source 4 and blue led light source 5 further to improve uniform illumination degree
Front end set uniform light board 6.
The present invention in use, the irregular thrust that its testee being directed to is paste solder printing to be formed on circuit boards,
It is less than 10mm, the measurement for not advising lateral process thing highly less than 1.5mm generally directed to diameter.As shown in Fig. 2 during operation of the present invention
Comprise the following steps：Testee 7 is placed in the lower section of the under shed of lampshade 1；Red, green, blue three coloured light distinguishes uniform irradiation（It is non-straight
Penetrate）On testee 7, camera 2 absorbs picture to the irradiation of three coloured light respectively；Pass through the gray scale operation of the picture of different colours
（The gray scale operation of picture is prior art, is not repeated herein）, calculate the vertically profiling of testee 7, i.e. testee 7 and exist
Area on circuit board.
Presently preferred embodiments of the present invention is the foregoing is only, the limitation not designed this case, all designs according to this case are closed
The equivalent variations that key is done, each fall within the protection domain of this case.
