The radiation efficiency of NUV-LED has reached more than 30%, and the radiation power of a single LED has reached more than ten watts, and is further improved. With the improvement of package power density and improvement of system design, high-power NUV-LED is expected to be truly applied in various UV fields and become a supplement and substitute for traditional UV discharge lamps. In the light curing industry, it can achieve substantial energy saving and improve coating quality, which has great application prospects.
Professional UV LED technology
DUV-LED is limited by the manufacturing process technology, and the chip efficiency is low. The radiation efficiency of the current batch products is less than 2%. Reducing the dislocation density of the active layer and improving the external quantum efficiency are the main research directions of DUV-LED chips.
The application effect of UV-LED in medical, testing, sterilization, disinfection, degradation, lithography and other fields has been verified and improved
The output power of the first-class standard laser is less than 0.4 milliwatts. This is because the laser with this energy will not cause damage to the eyes and skin under any conditions, and it will not cause damage to the human body even after being focused by the optical system. Damage, so this type of laser product is classified as a type that does not require special handling. Huizhou deep ultraviolet LED wholesale price

The second-level specification laser output power is between 0.4 milliwatts and 1 milliwatt, and the reaction time for a person to close their eyes is 0.25 seconds. The exposure calculated at this time cannot exceed the MPE value. Generally, lasers of less than 1 milliwatt can cause people to faint. Therefore, such lasers cannot be used to directly illuminate the eyes, let alone investigating such lasers with Yuanwang equipment.
If the laser beam of the third-level specification enters the eyes directly, it will cause damage to the eyes, and its output power is between 1 and 500 milliwatts.
The fourth-class standard laser is a high-output continuous laser whose output power is greater than 500 milliwatts, which may cause a fire hazard.
