特点

FALUX logo
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

*Included in HPRS Series.

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 from low angles to high angles

Provides diffused light from the LEDs without waste using a unique illuminating mechanism. Even if the distance from the workpiece to the Light Unit is changed, there is little variation in the uniform region and it can therefore be used for a wide variety of uses.

Achieves a uniform region with a high degree of freedom

Provides diffused light at high output

It achieves uniform illumination of diffused light at high output using surface-mounted LEDs and a specially processed diffusion plate.

FALUX / FALUX Sensing Technology

Did you know the LED brightness varies depending on ambient temperature?

Problem 1
Temperature changes influence brightness.

Increased temperature due to self-heating and changes in ambient temperature as air conditioning equipment starts up can affect the brightness of LED lighting.

`FALUX` Technology

Solution 1
Our FALUX technology automatically compensates for brightness fluctuations due to temperature changes.

Using the constant current circuit dependent on the input voltage, variations in the forward current of individual LEDs are corrected for uniform brightness. The temperature compensation circuit compensates for fluctuations in brightness due to changes in temperature.


Did you know the LED brightness will be decreased after 1,000 hours operation?

Problem 2
Need consistent brightness for long-term use.

On a fully operational 24-hour line, LEDs begin to lose brightness after about 1,000 hours, causing costly inspection failures.

Problem 3
Need consistent level of brightness across multiple light units.
Actual brightness of light unit is different on each inspection line even though the setting is the same.

`FALUX Sensing` Technology

Solution 2
Brightness is automatically adjusted to maintain initial settings after receiving a low brightness alarm.
Solution 3
Solved by using an absolute brightness monitor + copying setting values across all units


FB control

Eliminates variations over long periods. FB control fine tunes the output voltage to match the standard brightness. Output as a feedback error when the upper or lower output voltage adjustment limit is reached.

Problem 4
Different settings are needed one after another
Different settings or programs must be used depending on the camera, requiring extra time and cost.

Solution 4
Easy configuration with our original controllers.
