The Harm and Symptoms of Light Pollution

(Summary description)   You may not know that the common luminous billboards in life can kill about 300,000 insects in a year. This is a recent study by a scientist. In fact, the harm of light pollution around us is also very serious. In the process of bird migration, light pollution makes them lose their way during the migration process, causing them to crash into tall buildings and die.        Many dead baby turtles have been found along the coast of the Canine Ocean. According to the analysis, the newborn baby turtles swim to the ocean according to the reflection of the moon and stars in the water. The brightly lit cities along the Atlantic coast eclipsed the moonlight and starlight, causing the little turtles to mistake the land for the ocean and eventually die from lack of water. At night, the earth's atmosphere scatters city lights to maintain a high brightness. When animals are stimulated by light, they will be full of energy, and the energy originally used for reproduction, self-defense and foraging will be consumed for no reason. Environmental scientists have also found that trees that are in close proximity to strong light sources have shorter survival times, less photosynthesis, and less oxygen release. The above phenomenon of artificial light causing harm to animals and plants can be called "light pollution".        In fact, for humans, the harm of light pollution is not small. In recent years, the glass curtain walls of many tall buildings have caused light pollution. In the summer sun, the glass curtain wall is very uncomfortable. In addition to the glass curtain wall of the building, the color of the interior walls can cause visual discomfort if too bright. A very smooth white wall has a light reflectance of up to 90%, which is about 10 times higher than that of grass, forest or rough surface decorations. So when painting walls, it is best to use "ecological colors". The so-called ecological colors are soft natural colors, not bright and dazzling colors. Studies have shown that light pollution can cause damage to the cornea and iris of the human eye, inhibit the function of retinal photoreceptor cells, thereby causing visual fatigue and decreased vision. If you work or live under the conditions of severe light pollution for a long time, you will be dizzy and upset, and even have symptoms of mental weakness such as insomnia, decreased appetite, low mood, and physical weakness.

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.
