All About LED Technology

CRI is limited in its evaluation as it only considers the reproducibility of the light source for a small number of specific colors, while ignoring other important factors. The emergence of TM30,CQS and TLCI compensates for some of the shortcomings of CRI and provides a wider range of indicators for evaluating the colour reproduction ability of light sources.More color indicators are necessary to provide data support for users in various industries to make informed choices.

What is UV light? Ultraviolet light, as it says, refers to light beyond violet. According to the wavelength, ultraviolet light is divided into many different kinds, but in our lives, you and I usually contact these three: UV-A, UV-B, and...

Light is one of the most essential environmental factors for plant growth. It is not only the basic energy source for photosynthesis but also an important regulator of plant growth and development. Plant growth and development are affected not only by the light intensity (photon flux density, PFD), but also by the quality of light which means different wavelengths and radiation, and their different composition ratios.

LED phosphors are a crucial material in the manufacture of white LEDs. Phosphor chemistry and composition largely determine an LED’s efficiency, light quality and stability. Yuji is one of the very few LED companies in the world that has entire LED phosphors and packaging technologies. Multi-variety LED phosphors are the basis for YUJILEDS spectrum simulation.YUJI LEDS Phosphors consistent focus on improving the brightness and stability of red nitride phosphors has allowed us to become an industry leader in providing high CRI LEDs at efficiency levels and stability in line with standard CRI level LEDs on the market.The different types of phosphor have their own characteristics and uses.
