Lampshade, a cover placed on the periphery of the flame or on the bulb for concentrating or weatherproofing. The lampshade not only covers the lamp to gather the light together, but also prevents electric shock and protects the eyes.

The device developed by the University of Birmingham team can detect fluorescence at a specific wavelength to determine whether there is a corresponding microbiological and organic carbon in the water. The researchers said that using this equipment to "scan" the water, the test can be completed in as little as 30 seconds.
In contrast, the traditional method takes more than 12 hours to complete the water quality test, and the use of relatively high cost biochemical reagents cannot satisfy the needs of the disaster-stricken and poor areas to quickly find a clean water source.
Professor John Bridgeman, a University of Birmingham professor who led the project, said that the operation of this new device is very simple, and that ordinary people can quickly learn to use it, which is conducive to popularization in remote areas in the future.
According to reports, the research team has cooperated with a Chinese company to use this new device to assist a sewage treatment plant in Guangzhou to improve the efficiency of sewage treatment.
(Original Title: Water Testing Completed in 30 Seconds for New Equipment is Expected for Rescue and Sewage Treatment in Disaster Areas)
Water quality testing completed within 30 seconds of the development of new equipment in the UK
Recently, researchers at the University of Birmingham in the UK announced the development of a new type of optical device that can quickly detect whether the water quality meets the potable safety standards within 30 seconds according to the fluorescence characteristics of the water and is expected to be used for rescue in the disaster area. Sewage treatment and other aspects. According to the researchers, all water bodies emit fluorescence, but the human eye is not sensitive to specific wavelengths of light, so these fluorescence are not easily detected by the naked eye. Previous studies have shown that because of the different fluorescence characteristics of pollutants in water, water pollution can be identified by analyzing the water fluorescence.
