Sunlight Technology

For industrial use, the CIE illuminants (A / D50 / D65) are frequently required as references thus the lighting environments desire as close to the standard illuminants as possible. However, standard LEDs are always far away from these illuminants that cannot get a promising result and it is never about just increasing CRI numbers because the spectral quality is the vital factor for visual appraisal and measurement of color (e.g. ISO 23603, CIE S012/E).

Thanks to our deep research and development of the correct spectra of each color temperature, it is not surprising to receive positive performance and feedback based on different industrial standards and measurements. 

Improved luminous efficacy

Luminous efficacy is important whether for energy saving or simplifying the design of a lighting system, whereas the spectral quality is contrary to efficacy. When the spectrum covers a wider wavelength and equally distributes at each nanometer, less radiance will be involved in the effective lumen sensitive range relatively, then the luminous efficacy is difficult to be promising.

We optimize the LED die binning, and with the enhancement of Yuji phosphor solutions, this inevitable phenomenon is suppressed effectively that our sunlight spectrum LEDs reach the same efficacy or even surpass than a standard LED.

YUJILEDS® sunlight simulation product series

As the experts and pioneers in sunlight simulation technology, we focus on the elaborate solutions so deeply that we are the only one providing different concepts of full-spectrum LED products. Specified to 10nm distinction, our LEDs can be allocated to different applications precisely. Due to the difference in the spectrum, the differences in these solutions are reflected in many aspects. For this reason, we simply gave the main difference between the three mainstream products series (APS/AP/SunWave), and summarized them in the following table:
