High-Precision RGB Automatic white balance Tester

 

Introduction

(First version)

 

 

 

 

 

 

I,Instrument Overview

This instrument is dedicated to three colorsLEDAutomatic white balance test, using high-tech photoelectric sensor, automatic allocation through samplingRGBThree colorsLEDTo calculate the resistance value of each tube core that needs to be connected in series, so as to match the various colors required, the color effect is good, the accuracy is high, the test range is wide, it has the dual operation interface of manual buttons and computer software control. Applicable to three colors using resistance Color MatchingLEDProduction tests by manufacturers such as backlight and lighting.

After the coordinates and brightness required by the keyboard are input, the instrument will automatically light up three colors LED , Collecting data through Photoelectric Sensors , Compared with the data in the memory, CPU Based on the comparison data, issue commands to control three colors LED The current size of each tube core. When the data collected by the photoelectric sensor is the same as the data in the memory, CPU Issue command to stop data collection and stable three colors LED Current of each tube core, three colors LED In line with the required coordinates and brightness requirements CPU Process the converted data through LCM Or display it on the computer to achieve the purpose of color by allocating the resistance value.

2, Instructions for use

(1) Boot

Power plug in220/50Mains, and then turn on the host switch on the back of the chassis. The system enters the preparation status.

(2) Calibration instrument

From three colors LED Take a sample lamp from the packaging bag as the calibration lamp, place the lamp in the test fixture, and select 3. Sample led Calibration Post-Press Enter Key... , Use BM-7 Measure R , G , B And manually input the wavelength and brightness values to the instrument as the calibration data. LED The lamp is saved as a control sample and the calibration is completed.

(3) Settings

Remove the saved control sample lamp and mount it into the test fixture. Select2.Sample led ParameterPost-PressEnterKey...,After the calibration data is extracted, enter the coordinates and brightness values for the color. The instrument automatically colors the data. After the color scheme is complete, the instrument automatically saves the parameters as the control parameters.

(4) Test

put the three-color led into the test fixture and select 5. target led mixing press enter and the instrument starts to mix colors, when the color mixing is stopped, the instrument automatically switches to the data window and changes the current I , voltage v and resistance values to be matched r display. Click "automatically print" or manually record RGB resistance values required for each tube core, paste the printed / recorded labels to the corresponding led the test is completed on the packaging bag.

3And precautions

(1The instrument should be placed in a dry and ventilated place and kept clean. If not used for a long time, unplug the power plug and store it.

(2) Is not liable for faults caused by improper use or environmental exceptions.

(3The instrument must be properly grounded to ensure safe use.
