Embodiment Construction

[0009] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0010] A test method for automatically judging the color of an LED with three primary colors is provided, including the following steps:

[0011] (1) Light up the LED, the lighting time of the LED is about 1s, use the camera to capture the lighted LED instantaneously, the color of the LED can be captured, and the color light source illuminant can be transformed into a static color;

[0012] (2) Send the snapshot result to the Labview software for processing, the Labview software processes and judges the three primary...

Abstract

The invention discloses a test method for automatic judgment of LED color based on three primary colors. The method comprises the following steps: lighting an LED, and carrying out instant picture capture on the lighted LED through a camera; and sending the captured result to Labview software for processing, wherein the Labview software carries out processing and judgment on the three primary colors of the LED. Though the mode above, the test method for automatic judgment of LED color based on the three primary colors is characterized by carrying out instant picture capture through the camerawithin 1s when the LED is lighted, and carrying out color processing through the LABVIEW software according to the characteristics of the test product and based on the red-green-blue three primary color principle, and replacing manual judgment with automatic judgment, thereby overcoming the defects of artificial missed judgment and misjudgment and the like.

Description

technical field [0001] The invention relates to the testing field of LED products, in particular to a testing method for automatically judging the color of LEDs with three primary colors. Background technique [0002] Light-emitting diodes are referred to as LEDs for short. Made of compounds containing gallium Ga, arsenic As, phosphorus P, nitrogen N, etc. Visible light can be radiated when electrons and holes recombine, so they can be used to make light-emitting diodes. LEDs are used as indicator lights in circuits and instruments, or to form text or digital displays. Gallium arsenide diodes emit red light, gallium phosphide diodes emit green light, silicon carbide diodes emit yellow light, and gallium nitride diodes emit blue light. Due to chemical properties, it is divided into organic light-emitting diode OLED and inorganic light-emitting diode LED. The existing judgment of LED color is judged manually, which is easy to cause problems such as manual misjudgment and m...
