Nichia, the world’s largest LED manufacturer and inventor of the high-brightness blue and white LEDs, announces the addition of the first mid power LED capable of delivering the high-quality light necessary to meet the demands of telework and indoor video recording.

Over the past 50 years, Nichia has demonstrated its commitment to improving the overall performance and quality of light through its R&D and production for phosphors and LEDs. Since its invention of the high brightness blue LED and subsequent white LED, simply replacing traditional lighting technologies with more efficient LEDs has never been Nichia’s goal.

The European Broadcasting Union (EBU) Technical Committee has defined one indicator to express quality of light, the Television Lighting Consistency Index (TLCI). TLCI quantifies the color reproduction of illuminated objects when they are projected on a display through a camera. Video and images taken under high TLCI lighting have higher color reproducibility than those taken under ordinary LED lighting, allowing users to enjoy natural, vivid, and beautiful images on TVs, PCs, and smartphone screens.

Traditionally, TLCI has been an index that is often required for TV recording and broadcasting applications such as lighting in stadiums and indoor arenas. Nichia has had a high-power LED lineup with great TLCI metrics, specifically targeting stadium lighting, including the NV4WB35AM, NV4WB35AR and NVSW519A series. However, with the continued adoption of remote work as well as other new online activities, there is an increasing demand for indoor lighting with high color reproducibility through a camera, such as virtual meetings, video recordings and more. To respond to this demand, Nichia has developed and launched a TLCI option with the NFSW757G-P5H6/R9050j85t90, which achieves high TLCI metrics for lighting in indoor video production.

By combining Nichia’s unique phosphor technology and the TriGain® Technology of GE Current, a Daintree Company, this LED achieves high TLCI, high color rendering / TM-30 and high efficiency at the same time, something not possible with existing high color rendering LEDs. This LED enables the design of luminaires appropriate for telework, online meetings, indoor video recordings and photography with smartphones.

Same as LED lighting manufacture, although we are only focusing on the LED lightings for commercial refrigerator, cooling system, and shelf, we should like to learn the spirit of continuous improvement like Nichia, and work hard for improving people’s quality of work and life.
