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.

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 controller side.Based on the monitored values, feedback control can also beperformed from the OPPF or OPPD Series controller, making it possible to maintain the factory default brightness for around 40,000 hours.

Supports applications for a wide variety of industries

It is bright and even if the distance from the workpiece to the Light Unit is changed, there is little change in the uniform region. Therefore, it can be used in a wide range of industries.

Illuminates diffused light at high output

Light from the surface-mounted LEDs is diffused inside the dome-shaped reflective panel. The diffused light from the wide uniform region is illuminated evenly.
