Abstract

This research is motivated by the lack of a light intensity control system in the high power RGB-LED fluorescence imaging system that was created by previous researchers. This study aims to design and create a high-power RGB-LED fluorescence imaging system to control light intensity using Pulse Width Modulation (PWM) and LabVIEW software and integrate it with a high-power RGB-LED fluorescence imaging system. In addition, this study also aims to test the performance of a light intensity control system that has been created and is integrated with a high power RGB-LED fluorescence imaging system. This research was conducted in three stages, namely system design and manufacturing, system integration and system performance testing. The system design is made using SolidWork software. System development is done by preparing tools and materials, assembling components, and checking tools. The integration of the system is done by placing a light intensity control system that has been made on the casing of the high power RGB-LED fluorescence imaging system. System testing includes precision and linearity with duty cycle variations ranging from 0 to 100 at intervals 1 with repeated measurements of each duty cycle 5 times. The tests were carried out on each LED color, namely red, green, and blue. The results showed that the RGB-LED fluorescence imaging system using PWM and LabVIEW software have been successfully designed and created and integrated with high power RGBLED fluorescence imaging system. The precision (repeatability) of system that was created is high (very good) is as follows; for red LEDs at 99.03959152%, for green LEDs at 97.83846822% and for blue LEDs at 98.59290995%. In addition, the system created has a good linearity with results for red LEDs of 0.8352, for green LEDs of 0.9975 and for blue LEDs of 0.9991.
