"Cảm biến FALUX" cho phép theo dõi độ sáng và kiểm soát phản hồi
Using the constant current circuit dependent on the input voltage, variations in the forward current of individual LEDs are corrected for uniform brightness.
Meanwhile, the temperature compensation circuit compensates for fluctuations in brightness due to increases in temperature after lighting or changes in the ambient temperature.
LED brightness sensing is performed using multiple built-in photodiodes.
This allows for accurate measurement of LED brightness not only during continuous illumination but also with short period illumination.
Absolute brightness is stored in the lighting’s internal memory to allow for instrumental error adjustment.
“FALUX sensing” also makes it possible to measure both the LED brightness of lighting and the internal temperature, and then to monitor those measurements on the power supply side.
Based on the monitored values, feedback control can also be performed from the OPPF Series controller, making it possible to maintain the factory default brightness for around 40,000 hours.
The aluminum die-cast case is equipped with an LED board with a built-in sensor.
The first fixed lens optimizes the directivity angle of the LED, and the attachment lens can be used to switch the illumination angle.
At the same time, the fixed lens guides the light toward the photodiodes, which makes highly accurate sensing possible.
The optimal light working distance and field of view can be selected in the condensed and low-angle modes with the attachment lens attached or in the wide mode with the lens removed.
