Sunlight Technology
Sunlight is the ultimate pursuit of the artificial light source
The sun essentially provides complete and homogenous spectral radiation in the visual wavelengths at any time of the day, it offers natural light for comfortable sight and full-spectrum emitting for healthy biological effects, which makes the sun the most ideal light source, while theories of light-emitting of the artificial light sources, including the LED which is generally combined by the blue semiconductor die with phosphors, are far away from sunlight (blackbody radiation), therefore it is visualized to observe that artificial light sources cannot approach the real sunlight in spectral level, thus are unnatural effects.
YUJILEDS® sunlight technology, up to 99% similarity effectively
YUJILEDS® sunlight technology gives innovative and revolutionary solutions providing unprecedented Spectral Power Distribution (SPD) with ultra-homogeneous features. It mimics the natural light spectrum up to 99% similarity to the spectral engineering level, where a standard LED spectrum generally misses significant radiance and only constitutes less than 50% of the sunlight spectrum.
Simulating the spectrum is the essence of simulating the real sunlight, our technology makes it possible to “clone” the gene of the sun even if the luminescence principle is different, and the harmful UV (ultra-violet) and useless IR (near infrared) are cut out of the spectrum.
Higher than high CRI
99 CRI
As the new generation of high CRI LED lighting, and by mimicking the natural light spectrum, Our LED performs outstanding color rendition than the standard LED and high CRI LED.
Our sunlight spectrum technology becomes disruptive again to the market when high CRI LED lighting gets widespread. Up to 99 CRI, we surpass our high CRI technology by ourselves, it is not just a super-high CRI performance, but the individual Ri is steadily up to 100, making the color truly vivid without losing any details.
Superlative TM-30 metric valuation
With the metric of TM-30, Yujileds® sunlight LED presents even more extraordinary advantages. When CRI cannot finely distinguish color quality especially the metamerism phenomenon happens, the comprehensive evaluation methods of TM-30 provide the insightful results of the color metrics. Fidelity index (Rf) achieves 98, gamut index (Rg) achieves 100, accurate color vector, minimal chroma/hue shift, uniform and high fidelity of all 99 color samples, indicating the high-performance of the sunlight simulation.
100 TLCI
The color rendition and accuracy performance is not only for human eyes, but is also valuable for “electronic visual” like the camera sensors. Yujileds® sunlight LED achieves up to the full score of 100 TLCI (The Television Lighting Consistency Index) with zero incorrectness of the chromas, making it the ideal light source for the professional use of photography, television, broadcast, studio and cinematography lighting, it also indicates that the feature of a homogenous spectrum is significant to the non-visual, optical-electric devices.
Ideal simulation models of CIE illuminant
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:
|
|
Luminous Efficacy @0.2W |
Wavelength Coverage |
Color Rendering Ability |
|
APS Series |
Up to 165 lm/W |
420nm – 780nm |
Excellent |
|
AP Series |
Up to 140 lm/W |
400nm – 780nm |
Excellent |
|
SunWave Series |
Up to 110 lm/W |
380nm – 780nm |
Excellent |
More than the SunWave / AP / APS series LEDs
The story will not just end with the SunWave / AP / APS series LED with natural light and full-spectrum features, for specific applications, we develop specialized series LED, extending the spectrum coverage to UVA, near-infrared, or halogen-like that could start from 360nm and end to 1000nm, achieving the simulation of the sunlight or electromagnetic spectrum to a broader and precise scope.
