UV LED refers to the near-ultraviolet light emitting diode that can emit a wavelength of about 200~400nm. UV LED has the characteristics of low energy consumption, long life, good flexibility, wide applicability, environmental protection and pollution-free, low maintenance cost and high luminous efficiency. It is widely used in automotive, electronics, medical, photoelectric, printing, curing, home appliances, building materials, air and water sterilization and disinfection, among which UVA (long wave ultraviolet, wavelength 320~400nm) LED is an important kind of UV LED.

Liyang Optoelectronics actively responds to the "double carbon" strategy, practices green and low-carbon development in many fields, explores new paths of energy conservation and emission reduction in urban road lighting, and helps urban lighting to be more energy efficient and intelligent!

VCSEL (Vertical Cavity Surface Emitting Laser) is a vertical cavity surface emitting laser, which integrates the advantages of high output power, high conversion efficiency and high quality beam. Compared with LED and EEL (edge emitting laser), In accuracy, high density, miniaturization, low power consumption, reliability, high life and other aspects of the advantages.

When it comes to ultraviolet (UV), everyone's first reaction is the radiation of sunlight, in fact, the common ultraviolet light is divided into UVA, UVB and UVC three kinds. Among them, UVC radiation is a recognized disinfection method, which is suitable for air, water and object surface disinfection.

Recently, in response to the recent complex situation of domestic epidemic prevention and control, Liyang Optoelectronics actively practiced the "people-oriented" management concept, insisted on putting the health of employees in the first place, and became a strong backing for employees in a special period.
