NLUD Dimmable Surface Emitting LED Lighting for Visual Inspection product image

Features

Surface-emitting LED lighting with dimming function, touch-controlled dimming design with no stage dimming in the range of 20% to 100%.

With a brightness storage function, the brightness can be reproduced when the power is turned off and on again. (If the electrical outlet is unplugged, the lighting brightness storage record will be reset.)

LED's unique non-glare surface emitting lighting emits evenly and naturally, so your eyes will not feel tired even if used for a long time.

The low-reflection surface-emitting design improves visibility and is ideal for inspection lighting.

Low-Flicker LED Illumination

IEEE 1789 (Recommended Practices for Modulating Current in High-Brightness LEDs for Mitigating Health Risks to Viewers) recommends a flicker percentage of 8% or less. At around 3%, flicker is barely perceptible to the human eye.

NIKKI LED lights feature an exclusive low-flicker design that reduces the flicker percentage to less than 2%. This minimizes flicker not only during standard still-image and video recording, but also when capturing high-speed video at frame rates such as 240 fps. As a result, these lights are ideal for precision imaging applications, including machine vision, image inspection, and visual inspection.

What is Color rendering (Ra)

NLUD Dimmable Surface Emitting LED Lighting for Visual Inspection application example

Color Rendering Index is an indicator used to express the degree to which a light source reproduces the Color of an illuminated object.

The higher the Color rendering, the more natural colors can be displayed as seen in sunlight.

If the Color seen under the light source is exactly the same as that under natural light, the Color rendering property is 100. The lower the value, the greater the Color difference from that under natural light.

Light sources with high Color rendering properties are suitable for applications such as painting or finished product inspection that require Color confirmation.

Special Color rendering index R1～R15

Average Color rendering index (Ra)

The numerical value obtained by averaging the Color rendering evaluation numbers of the eight test colors (No.1 to No.8).

Special Color rendering index (Ri)

In addition to the average color rendering index Ra, this evaluation also checks key colors such as red (No. 9), yellow (No. 10), green (No. 11), blue (No. 12), Western skin tone (No. 13), leaf green (No. 14), and Japanese skin tone (No. 15).

Comparison with standard Model (Ra80 5700K)

Compared with standard Models, the average Color rendering index of the Ra95 5000K specification is 97.3, enabling accurate Color recognition even in environments that require a high degree of Color reproduction.

NLUD20-AC(Ra80 5700K)
