How to maintain and select the uvc irradition power?

Irradition power decline  

At present, the most common problem with the use of ultraviolet disinfection and germicidal lamps is that the decline in the intensity of the lamp's radiation has  been ignored by the users. As long as the uvc light is on, then it has the ability to sterilize. Reckoning the quality of the tube, the quality of the tube is evaluated according to the concept of the general use of fluorescent lamps. Also, the intensity of visible light and the degree of freeness of visible light are used to judge the quality. Such a method is easy to be misunderstood, and will continue to be used for lamps with disinfection and sterilization capabilities. Of course, it will also violate the thorough disinfection and sterilization of items, mistakenly believe that disinfection and sterilization have been completed, and use it. As a result, the result of infection, poisoning, and disease, but the cause of the disease cannot be found.

Regular Cleaning

The penetration ability of ultraviolet rays is not as high as imagined. Any piece of paper, lead glass, or plastic will greatly reduce the radiation intensity. Therefore, dust and oil stains on the lamp tube will directly affect its penetration ability. Therefore, before using the new lamp, wipe it with 75% alcohol gauze to remove oil stains, hand sweat and dust. The lamps and quartz tubes in use should also be wiped and cleaned regularly to avoid affecting the UV transmittance and irradiation intensity.

Ultraviolet lamps are made of pure quartz glass tubes made of natural crystal. At present, high borax glass tubes can also be used instead of high borax glass tubes due to different costs and uses. Their characteristics and effects are quite different. Therefore, the price is also several times different, so different choices should be made depending on the place of use. The ultraviolet transmittance of pure quartz tube is more than 80%, and the ultraviolet transmittance of high borax glass tube is less than 50%.

In addition, the uvc led with ball lens can emit more irradition power than that without lens.

for example, 60leds 12v uvc led strip with beam angle 60° vs normal 60leds 12v uvc led strip.
