Leduvc 3535 0.5W purple sterilization lamp

UVC is a short wave ultraviolet Bai line.


The UVC band of ultraviolet, with a wavelength of 200 ~ 275nm, is also known as Du short wave sterilization ABCD ultraviolet. The ultraviolet sterilization lamp Dao emits UVC short wave ultraviolet.


UVC has the weakest penetration ability of short wave ultraviolet rays, and can not penetrate most transparent glass and plastics. The short wave ultraviolet contained in sunlight is almost completely absorbed by the ozone layer.


1. UVC, full name: USB video class or USB video device class. It is a protocol standard defined for USB video capture devices jointly launched by Microsoft and several other device manufacturers. At present, it has become one of the USB org standards.


2. Advantages of using UVC USB has also become a standard in video, and the hardware will run more smoothly among various programs.


3. UVC band of ultraviolet, with a wavelength of 200 ~ 275nm, also known as short wave sterilization ultraviolet. It has the weakest penetration ability and cannot penetrate most of the transparent glass and plastic. The short wave ultraviolet contained in sunlight is almost completely absorbed by the ozone layer.


4. Short wave ultraviolet radiation does great harm to human body. Short time irradiation can burn the skin, and long-term or high-intensity irradiation can also cause skin cancer. The ultraviolet sterilization lamp emits UVC short wave ultraviolet.


The 3535 LED light source is a high-performance energy-saving device that can handle high heat and high drive current. The Purple LED light source with peak wavelength ranging from 270nm to 280nm and 390-405nm. This part has a foot print that is compatible to most of the same size LED in the market today.
