IP Rating Guide – How to Choose the Right Ingress Protection for Your Product

International Trade Manager, Qingdao LYD Electronics Co., Ltd.

Leyun's journey with light began 15 years ago, staring at her first soldered LED circuit board in a small university lab. That tiny flicker sparked a career. Today, she leads international trade at LYD Electronics, where she has helped engineer UV disinfection modules for global home appliance giants and illuminated countless commercial spaces with custom LED solutions.

What drives her? A genuine belief that light—whether purifying water, sanitizing hospital air, or accenting a retail display—can solve real-world problems. When she's not discussing UVC wavelengths with clients or optimizing logistics for bulk shipments, you might find her hiking with a UV flashlight, testing its beam on rocks (yes, her family finds it odd too).She writes here to demystify LED technology and help global partners navigate the complex world of Chinese manufacturing—one honest conversation at a time.
