LED lighting has become the mainstream of lighting industry because it’s energy saving, durable, and non-polluting. However, a lot of new issues resulted from LED light development, and the importance of LED light measurement is also increasingly being valued by this market.

We hereby illustrate why the LED measurement is important :

(The warm white spectrum of traditional light)              (The warm white spectrum of LED light)

By the spectrum, we can see the blue wavelength (400 nm ~ 500 nm) of LED light is higher than traditional light source, this high-energy visible light will stimulate your brain to be in exciting status and disturb biological clock, as well as the high-energy visible light will also hurt human’s eyeball and cause the macular degeneration, it is the reason why the market is full of anti-Blu-ray-related products in recent years.

Lighting Passport with the dedicated App, Spectrum Genius, can help users to quickly get the light source’ spectrum, and output the 1 nm high-resolution diagram to the user’s mobile device, while also providing comparison feature that allows user to compare two measurement spectrum, or with the built-in benchmark spectrum.

In addition, the color space is also an important indicator of the detection,

————(CIE1931 Color Space)                                           (LED Bin)

In the color space, traditional light must fall on Planckian Locus (the black thick line), but the LED light source is different, any of fall on the red line can be called the same color temperature (CCT), and it makes two different light color show the same CCT. Although LED manufacturers set LED Bin table to sort the chips, but lighting manufacturers and consumers are still afflicting on numerous supplier’s different Bin table.

Lighting Passport provides complete color space information anytime, anywhere, and the CIE chart allows users to determine its light color clearly and quickly. Lighting Passport can also show the measurement result on ANSI C78.377 standard quadrangle, it can make users directly refer for the international standard, not the chaotic BIN table.
