APS LED SMDs

Yujileds® APS series LED is designed for creating a new era of natural lighting spectrum LED with superb color rendering performance. Improving the artificial lighting as close to the sunlight is the eternal pursuit for the top LED manufacturers. However, the artificial lighting gets far away from the naturalness after the incandescent and halogen because the illumination principles of the later artificial lights are far away from the blackbody radiation, including LED.

The sun essentially provides complete and homogenous spectral radiation in the visual wavelengths, while an LED is always combined by the blue or purple semiconductor die with blue/green/amber/red phosphors, in consequence, it is visualized to observe that from an LED spectrum, peaks and gaps always exist because of the respective characteristics of the die and phosphors, which can not be avoided generally.

99% similarity to the sunlight spectrum

Yujileds® APS series LED is based on innovative and revolutionary technologies. It provides an unprecedented spectrum with ultra-homogeneous features within one compact package, where the color rendition performs superbly and stably. Compared to these standards, the APS spectra achieve 99% similarity within one compact package, unprecedented for all of the Yujileds® high CRI LEDs ever. Compared to other sun spectrum LED solutions, the APS series LED utilizes the die and phosphor technologies effectively that achieves full-spectrum coverage in visual wavelengths, which improves the luminous efficacy (lm/W) and maintenance to a great extent.

Refuse any peaks or gaps

Ideal illuminants always present completely uniform spectral power distributions, such as sunlight where a recent artificial light source can never simulate to a promising degree, especially for LED considering its particular illuminating principle. With the latest technology of Yujileds® phosphor and package, it is finally available to achieve homogeneous spectra and there is no longer a strong peak or obvious gap like a standard LED.

Ri up to 100, steadily

Yujileds® APS series LED is equally top level under CRI metric system. Achieving up to 99, R1-R15 all above 90 or even 100, the APS series LED performs steadily in color rendition, which helps with reducing the concerns of the imperfection when rendering specific colors. Even for the always mentioned contradiction between R9 and R12 is well solved in the APS series LED.

Superlative performance in TM-30 metric valuation

TM-30 is widely recognized as the new and more comprehensive metric to evaluate the color rendition of the LED light source, it provides more references including color fidelity and gamut from 99 evaluation samples, which means, compared to conventional metrics, the TM-30 will disclose more details to present the most authentic performance on color rendition. The APS series TM-30 measurements are the most intuitive testifications. Given the Rf 98 Rg 100, and the average of all 99 color fidelities above 95, each color fidelity is more than 90. These values mean that Yujileds® APS series technology wins the highest level on the color rendition, not only for individual metrics but is stable quality.

Specialized Standard White binning

In order to provide highly consistent chromaticities, Yujileds® offers ANSI 3-step bin, and with SimpleBinning technologies based on Yujileds® module, the lighting design is simplified greatly but no compromise on color quality, the equivalent consistency can be expected to 2-step SDCM.

The first choice for high-performance LED

The revolutionary meaning of Yujileds® APS series LED is not only about its remarkable spectrum quality, but is the balanced achievement of cost, efficacy, maintenance and color rendering. Compared to competitors’ LED, the APS series LED is more friendly for commercialization in different applications.
