What are FALUX and FALUX sensing?
CCS FASTUS LED lighting is equipped with a proprietary technology designed to maintain brightness automatically over long periods by detecting the temperature and brightness of the lighting.
Problems with LED Lighting
Problem 1: Variations in brightness between individual LEDs
Because variations in forward voltage of individual LED can affect the brightness of the LED, the forward voltage must be aligned through sorting or some other means.
Problem 2: Fluctuations in brightness due to heat generated by the LED
When LED lighting is turned on, the LED itself generates heat, causing temperature to rise.
As the internal or ambient temperature rises, the brightness decreases.
Problem 3: Management of long-term variations in brightness
After 40,000 hours of use, the brightness of LED lighting drops by 50%. This means that brightness must be adjusted when used for long periods.
Outline of FALUX and FALUX sensing
Features of FALUX
Built-in “FALUX” circuit to correct variations in brightness
*Included in all models.
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.
- FALUX not included
- In order to reduce LED forward voltage variations, the LEDs needed to be sorted according to their Vf measurement. Moreover, illumination efficiency dropped as the temperature increased, reducing the brightness.
- FALUX included
- The brightness of each LED is fixed, virtually eliminating variations in brightness following increases in temperature. Whether with continuous illumination or ON/OFF control, brightness remains fixed.
Features of FALUX sensing
Equipped with “FALUX sensing” for monitoring brightness and temperature through sensing
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.
