日亚化学全面的UV LED产品组合，旨在取代UV灯

日亚化学（Nichia）是一家领先的光电半导体制造商，一直致力于先进技术的创新，以适应广泛的应用领域 引领 和激光二极管行业。该公司通过其全球主要代表和合作伙伴建立的网络始终保持全球影响力。集邦咨询有幸采访到日亚化学公司经理林秀树先生，了解该公司在UV LED领域的技术进展以及市场前景和前景。

Due to the COVID-19 pandemic, the UV-C LED market had a significant surge in demand. After the pandemic influence slowed down, however, the market has been troubled by defective products and vicious price wars, causing UV LED players and the entire market to struggle. Nevertheless, Nichia holds that the UV-C LED still has good market potential thanks to its long lifetime and simplicity for optical design compared to UV lamps. Once the UV-C LED reaches the ideal efficiency (WPE ≥10%), there is a chance for it to replace UV lamps, especially for water sterilization market. Therefore, Nichia has constantly been developing UV-C LED products. For example, the 280nm 110mW UV-C LED boasts a 5.4% WPE and a lifetime of >10,000 hours (L70) at junction temperature of 90℃.

由于UV灯具有从UV-A到UV-C波长的宽波段范围，Nichia现已成功在市场上推出308nm UV-B LED。 UV-B LED的潜在市场包括光疗（牛皮癣、汗症、白癜风、特应性皮炎、湿疹等）、园艺照明和固化。目前，308nm 90mW UV-B LED (5.1% WPE) 已首次上市。

日亚化表示，固化、喷墨打印、空气净化等应用领域的UV-A LED市场需求在2024年将保持稳定。为了完善UV LED产品组合以匹配UV灯的宽频波长优势，日亚化还展示了330nm 100mW市场上的 UV-A LED (5.7% WPE)。同时，公司强调365nm UV-A LED品质，以引起市场关注。

日亚化学以其卓越的产品质量和使用寿命以及全面的产品组合平台而享誉国际。因此，日亚化学表示，公司将持续利用其研究资源和先进技术，继续向市场展示新产品，以满足全球需求。
