High-Speed Camera ＋ data Logger = PLEXLOGGER The ultimate solution for dramatically increases the efficiency of evaluation and verification on site

The LED has attracted attention in various fields in recent years. We feel pleased that we can produce beautiful colors while controlling the power consumption and overcoming problems associated with exhaust heat. We use the data logger and oscilloscope to detect problems that are not evident but likely to occur.I Occasionally, we used to lease a high-speed camera to detect problems; however, we were not able to identify the causes of the problems from the video taken with the camera, which we now regretfully recall.

We had no other option because there was no specific method to “decide the appropriate LED color” from high-speed videos of the flashing LED. On the other hand, we were asked to increase the speed that is unique to the industry through ways such as the use of a more efficient design process (with fewer simulations and prototypes). We strongly recognized the need for an analysis tool that would facilitate the synchronization of analog waveforms and high-speed video and help ensure efficient visualization and data sharing. Under the circumstances, the development of a blue LED element faced the same problem.

We still remember the time when we were shown the video of a blinking LED synchronized with the voltage waveforms by using PLEXLOGGER. We felt a sense of relief because we were almost certain that “this is the solution!”

Owing to confidentiality reasons, we cannot reveal details of the improvements; however, we can declare that PLEXLOGGER helped us.

The standard accessory analysis software “PLEXLOGplus” was also helpful in the analysis process. By performing RGB analysis and analysis of brightness changes, we improved the thickness and the color unevenness of the phosphor and reviewed the lens shapes and conditions used for dimming control to consider the possibility of mass production and costs. This may sound unbelievable, but we were able to solve all problems together by providing the recorded video and waveform data to experts and by conducting simply and a common job that is easy to understand and convey in a simple and quick manner. As for the blue LED, we were able to magnify the LED element approximately 150 times with our microscope, thanks to the C-mount lens, for a wider range of applications.

We were attracted to the PLEXLOGGER because it is compact in size and it is an all-in-one unit that allows synchronization between the high-speed camera and data logger. PLEXLOGGER also has excellent cost performance in terms of man-hours saved, which would otherwise be required for preparing and connecting devices that are necessary for other data loggers. As the conversion of the video into AVI format and Jpeg images was easy and as the extensibility was high, PLEXLOGGER was easy to use. We are very proud that we have started to create a framework for passing the analysis video taken with PLEXLOGGER as knowledge database to the next generation development.
