Twice the brightness of conventional products

The OPR-SF Series is lighting control-specific ring lighting that offers ultra-high-intensity illumination close to that of strobe lighting with strobe control unit even when connected to a 12 V general purpose power supply. Because longer illumination times than strobe lighting can be ensured, severe timing adjustments for the camera shutter and lighting necessary with strobe lighting are not required. In addition, highintensity illumination is possible for illumination times of 1 ms or longer, allowing for even brighter images to be captured with slow shutter speeds.

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.
