Detection method for light splitting and color separation of LED lamp

Abstract

The invention discloses a detection method for light and color separation of LED lamps. The detection method comprises the following steps: taking a plurality of LED lamps with the same model as a group of test objects; continuously shooting the same group of LED lamps by adopting a dynamic capture camera to obtain a plurality of groups of photos of the same group of LEDs; transmitting the obtained multiple groups of pictures to a computer terminal, performing digital calculation on the hue, saturation and brightness of the light in the multiple groups of pictures through image acquisition and processing software, and converting the hue, saturation and brightness into corresponding RGB (Red, Green and Blue) values; rGB value information corresponding to a plurality of LEDs in each image is calculated and numbered, and the corresponding RGB value information is stored in a computer system; the obtained RGB value information of the LED lamps is compared with the stored qualified RGB reference value information, the qualified LED lamps are screened and judged, the stored RGB values of the qualified LED lamps serve as a comparison database, the stored RGB reference values serve as double references, the remaining LED lamps are detected and compared, and the method has the advantages that LED lamplight and colors are rapidly analyzed, and the detection precision is accurate.

Description

technical field [0001] The invention relates to the technical field of LED lamp detection, in particular to a detection method for light separation and color separation of LED lamps. Background technique [0002] The LED light is an electroluminescent semiconductor material chip, which is cured on the bracket with silver glue or white glue, and then connects the chip and the circuit board with silver or gold wires, and is sealed with epoxy resin around it to protect the inner core wire. It is a solid-state semiconductor device that can convert electrical energy into visible light. It can directly convert electricity into light. The core of the LED is a semiconductor chip, and one end of the chip is attached On a bracket, one end is the negative electrode, and the other end is connected to the positive electrode of the power supply, so that the whole chip is encapsulated by epoxy resin. [0003] With the continuous increase of market demand, LEDs also appear in different col...

Problems solved by technology

[0003] With the continuous increase of market demand, LED lights of different colors have appeared correspondingly. After production, the color of the light needs to be tested. In the prior art, manual observation is often used for detection. The color of the bright light can be distinguished, but the traditional method is limited by human factors, which is prone to errors in test results. At the same time, the efficiency of the test is low, which limits the production efficiency of LED lights. Failure to test will lead to the failure of the produced LED lights. The unqualified color will affect the overall production quality, and an LED detection method is urgently needed to solve the above problems
