How much radiation do fluorescent lamps

(Summary description) As we all know, prolonged exposure to ultraviolet radiation will kill a large number of human cells. So, how many people pay attention to the invisible ultraviolet rays contained in ordinary energy-saving lamps and fluorescent lamps, and how many people know how harmful it is to the human body? American biochemist Anderson found that people who lived or worked under fluorescent lights for a long time received 50% more ultraviolet radiation than those who did not often receive fluorescent lights, and their skin cancer rates were also higher than normal. People are much taller. LED fluorescent lights, LED roadway lights, partition LED roadway lights, LED downlights, LED lighting projects In addition, the light waves emitted by fluorescent lamps can lead to the genetic degeneration of a large number of cells in the organism, increasing the number of abnormal cells and the death of normal cells. LED fluorescent lights, LED roadway lights, partition LED roadway lights, LED downlights, LED lighting projects In my country's large and medium-sized cities, about 40% of the lamps in ordinary households are fluorescent lamps, about 80% in offices, and more than 95% in school classrooms. However, tests have shown that most fluorescent lamps have varying degrees of UV radiation, and some UV radiation even reaches the level of disinfection and sterilization. The Shanghai Lighting Society conducted a survey on topics such as "the relationship between lighting and adolescents' vision health". Among them, Professor Xu Xueji of the Institute of Electric Light Sources of Fudan University found in the process of testing a variety of energy-saving fluorescent lamps on the market that one of them actually emits ultraviolet rays of 254 nanometers. Xu Xueji said that this result is very surprising, because fluorescent lamps use ultraviolet rays to excite phosphors to emit light. All fluorescent lamps (including energy-saving fluorescent lamps) will have ultraviolet rays, but the ultraviolet rays in those lamps are so strong that they can be directly used for disinfection and sterilization. If it is used for short-range lighting, it is very likely that the eyes will be harmed unknowingly. LED fluorescent lights, LED roadway lights, partition LED roadway lights, LED downlights, LED lighting projects According to Wu Hong, an expert from the China Green Lighting Project Promotion Office, they are also worried after testing many representative brands of fluorescent lamps in the Shanghai market, because most of them have different levels of ultraviolet radiation. When the distance from the fluorescent lamp is 1 to 2 meters, the ultraviolet rays will have a certain degree of damage to the human eye, and within 0.6 meters (generally the height of the lamp does not exceed this distance), the damage will be aggravated. In addition, due to the promotion of energy-saving fluorescent lamps, the number of households using fluorescent lamp table lamps in large and medium-sized cities has increased from about 20% five years ago to about 40% now, which makes the potential harm of ultraviolet fluorescent lamps continue to increase.

What are the characteristics of LED roadway lights? Do you know the installation method and precautions? Take a look!

  As people's requirements for lamps are getting higher and higher, a new type of lamps called LED lamps are favored by people. LED is a kind of light-emitting diode. As a light source for illuminants, it has high light efficiency and long life. To achieve multi-purpose lighting, and softened, it will not cause dazzling or other uncomfortable reactions, so many public areas will use this kind of light, such as LED roadway lights, because there are many people on the road, so it is necessary to To install soft lamps that will not hurt the eyes, what are the characteristics of LED road lights? Do you know its installation methods and precautions? Let's follow the editor to learn about it.    Features of LED roadway lights: 1. The color purity of LED roadway lamps is high; at present, LED products cover almost the entire visible spectrum range, and the color purity is high. 2. LED roadway lamps have a long life. The actual life of LED is more than 50,000 hours, which is several times or even dozens of times that of general light sources. 3. The light source of LED roadway lamps does not contain mercury, and the light beam does not contain ultraviolet rays. 4. It is solid luminescence, good shock resistance, firm and reliable. 5. It also has the characteristics of energy saving, economical and maintenance-free. 6. LED has strong luminous directionality, high luminous flux utilization rate, and small size, which is easy to design and control light intensity distribution of LED lamps. 7. LED roadway lamps can be powered by DC low voltage, which is safe and reliable. 8. The LED is not limited by the start-up temperature, it can be started temporarily, usually a few ms, and can temporarily achieve full luminous flux output.   Installation method and precautions of LED roadway lights: 1. Installation method: 1. First, determine the installation position and method of the lamps according to the actual needs of the work site, and then prepare the corresponding length of Φ8~Φ14 mm three-core cables according to the distance from the lamps to the power contacts. 2. Open the set screw on the side of the upper cover of the lamp, then loosen the compression nut of the cable inlet of the lamp, open the upper cover, and lead the power cables through the compression nut to the internal terminal, and connect according to the method shown in the figure. Fix it, and then tighten the cable compression nut and the upper cover of the lamp. 3. The LED roadway lights are enclosure-free. If the lamps themselves are not bright, generally communicate with the manufacturer for direct replacement or return to the factory for maintenance. 2. Notes: 1. The power supply must be cut off before dismantling the lamp. 2. It is strictly forbidden to open it with electricity. 3. During use, the surface of the lamp has a certain temperature rise, which is a normal phenomenon; the center of the transparent part has a high temperature and should not be touched. 4. When installing lamps, the lamps should be safely grounded nearby. The above are the characteristics of LED roadway lights, as well as its installation methods and precautions. Relevant staff must pay attention to the problems during installation to ensure their personal safety.
