From the perspective of time dimension, the application direction of UVC can be divided into short-term market and medium and long-term market. The short-term market includes household air conditioner, humidifier, air purifier, intelligent garbage pass, electric toothbrush sterilization box, water dispenser, ice maker, intelligent toilet and food preservation; The medium and long-term market includes commercial air conditioners, vertical air conditioners, sterilization of mother and baby products, sterilization of overflow direct drinking water, etc.

UVC: the first choice of healthy light source UV (ultraviolet) refers to the electromagnetic wave with the wavelength between 10nm-400nm, that is, ultraviolet. According to the wavelength, ultraviolet can be divided into long wave ultraviolet (UVA), medium wave ultraviolet (UVB) and short wave ultraviolet (UVC). The wavelengths are 320-400nm, 280-320nm and 100-280nm respectively.

Ultraviolet (UV) occupies the electromagnetic spectrum between X-rays and visible light. The sun emits ultraviolet rays. However, most of them are absorbed by the earth's ozone layer. Just as visible light consists of different colors in a rainbow, the ultraviolet radiation spectrum is divided into three regions, called UVA, UVB and UVC. When sunlight passes through the atmosphere. All UVC and most UVB are absorbed by ozone, water vapor, oxygen and carbon dioxide. UVA is not filtered so obviously by the atmosphere. Their biological activity and degree of penetration into the skin are different

In Europe at the end of the 19th century, smooth beaver fur hats and silk hats prevailed among princes and nobles, affecting folk fashion. It is found that rabbit skin can also be used to make top hats with the same texture without using rare beaver skin. However, the skin and meat of rabbits are closely connected. If Hatters want to separate rabbit skin and meat, they must use a substance - mercury.

How does UVLED dissipate heat 1. Heat generation must be controlled during use. The chip temperature in the drive is affected by the thermal resistance of the circuit board and the configuration density of the LED. Therefore, in the circuit board design, pay attention to dispersing the heat and prevent the LED junction temperature (TJ) from exceeding the absolute maximum rating. 2. The driving current of this product should be determined according to the ambient temperature (TA), and the heat generated should be dissipated. 3. The following two methods can be used to calculate the junction temperature (TJ)
