Abstract
The invention discloses a kind of method of testing of three primary colours automatic decision LED color, including step to be：LED is lighted, the LED lighted instantaneously captured using camera, the candid photograph result is sent to Labview software processings, the Labview softwares carry out processing judgement to the three primary colours of the LED.Through the above way, the method of testing of the three primary colours automatic decision LED color of the present invention, according to the feature of test product, it make use of red-green-blue principle, captured using camera within the 1s times that LED is lighted and color is handled by LABVIEW softwares, substitute artificial judgment using automatization judgement, make up manually fail to judge, judge by accident etc. and lack.
Description
Technical field
The present invention relates to the testing field with LED product, more particularly to a kind of three primary colours automatic decision LED color
Method of testing.
Background technology
Light emitting diode is referred to as LED.It is made up of Ga containing gallium, arsenic As, phosphorus P, nitrogen N etc. compound.When electronics and hole
Compound tense can give off visible ray, thus can be used for that light emitting diode is made.LED is used as indicator lamp in circuit and instrument,
Or composition word or numerical monitor.Gallium arsenide diode glows, gallium phosphide diode green light, silicon carbide diode jaundice
Light, gallium nitride diode blue light-emitting.Because chemical property divides Organic Light Emitting Diode OLED and inorganic light-emitting diode LED again.It is existing
Some judgement LED colors easily cause the problems such as manually failing to judge, judging by accident, so as to cause product by manually being judged
Color LED do not work, or color mistake causes defective products shipment into client's hand.
The content of the invention
The present invention solves the technical problem of provide a kind of method of testing of three primary colours automatic decision LED color, energy
Enough eliminate the deficiency of artificial judgment.
In order to solve the above technical problems, one aspect of the present invention is：A kind of three primary colours automatic decision is provided
The method of testing of LED color, including step is：LED is lighted, the LED lighted instantaneously captured using camera,
The candid photograph result is sent to Labview software processings, the Labview softwares are handled the three primary colours of the LED
Judge.
In a preferred embodiment of the present invention, the camera is USB camera.
In a preferred embodiment of the present invention, the three primary colours are red, green and blueness.
In a preferred embodiment of the present invention, the Labview softwares are by collection image, image analysis, color point
Analysis, result judgment step obtain result.
The beneficial effects of the invention are as follows：The method of testing of the three primary colours automatic decision LED color of the present invention, produced according to test
The feature of product, red-green-blue principle is make use of, capture and pass through using camera within the 1s times that LED is lighted
LABVIEW softwares are handled color, substitute artificial judgment using automatization judgement, are made up manually fail to judge, judge by accident etc. and are lacked.
Embodiment
The technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described implementation
Example is only the part of the embodiment of the present invention, rather than whole embodiments.It is common based on the embodiment in the present invention, this area
All other embodiment that technical staff is obtained under the premise of creative work is not made, belong to the model that the present invention protects
Enclose.
A kind of method of testing of three primary colours automatic decision LED color is provided, including step is：
（1）LED is lighted, the LED lighting times are about 1s, and the LED lighted is instantaneously grabbed using camera
Clap, LED color can be captured, color light source illuminator is changed into static color；
（2）The candid photograph result is sent to Labview software processings, the Labview softwares enter to the three primary colours of the LED
Row processing judges that parsing red, green, blue three primary colours color by Labview softwares is converted to number format, so as to judge whether
In regulating scope.
Wherein, the camera can be USB camera, conveniently used and taken pictures.The Labview softwares pass through
Collection image, image analysis, color analysis, result judgment step obtain result.There are currently no camera and LABVIEW two
Combine the technology parsed to color LED, it is not all right to the identification of colorful light-emitting light source to have using Keyemce,
The beneficial effects of the invention are as follows：
First, according to the feature of test product, red-green-blue principle is make use of, using shooting within the 1s times that LED is lighted
Head is captured and color is handled by LABVIEW softwares；
2nd, substitute artificial judgment using automatization judgement, make up and manually fail to judge, the missing such as erroneous judgement.
Embodiments of the invention are the foregoing is only, are not intended to limit the scope of the invention, it is every to utilize this hair
The equivalent structure or equivalent flow conversion that bright description is made, or directly or indirectly it is used in other related technology necks
Domain, it is included within the scope of the present invention.
