Degrees of protection and protection levels make it safer to handle electrical equipment if you can understand them correctly and use the equipment accordingly. We clarified the label jungle. Here you can read the basic knowledge of these two terms, taking the lamp as an example, which protection levels and IP protection levels are required for installation in different locations. Why is there a protection level? For lights, electric drills, or cable reels, whenever electricity is involved, safety is the top priority. For electrical installations, multiple DIN and VDE standards are defined. Because electricity can neither be seen nor touched, but electric shocks can be fatal. Therefore, it is not only do-it-yourself and builders who rely on well-defined standards, reasonable protective measures, and last but not least high-quality electrical equipment to prevent sudden electric shocks. This equipment can be used as emergency brakes to shock. Electrical equipment is constructed accordin...

Modern life makes people's lives brighter and brighter, even at night like daytime. Excessive lighting will have a serious impact on human health. 2/3 of people live in light pollution A survey report in the United States shows that about two-thirds of the world's people live in light pollution. Moreover, the pollution caused by man-made light is increasing year by year, with Germany increasing by 6% each year, Italy and Japan by 10% and 12% each year. One in ten drivers in the world said that when driving under the scorching sun, they would be suddenly attacked by the reflected light from the glass curtain wall, making them instantly blind to the direction. Dr. Russell Leiter, an endocrinologist at the University of Texas Health Science Center in the United States, even said: "Light is a drug. Misuse of light is harmful to health." The influence of light pollution on starry sky observation There are two ways for light pollution to interfere with our space research. ...

40, 60, or 100 watts? E27 or E14? For decades, when buying new light bulbs, consumers only had to make sure that the power was right and that the light source fits into the lamp or the corresponding socket. That was it. The emphasis is on was. Because those times are over since the ban on incandescent lamps in the European Union. The LED has long since established itself as a modern because it is efficient, light source, and is still in the advance. Associated with this, however, are many questions that consumers ask themselves again and again when they stand in front of the shelf: What does all the information on the packaging mean? And how do I find the light source I'm looking for? We want to try to bring the proverbial light into the dark and therefore explain in this light source guide which information has which meaning. After all, when choosing the right light source, it is no longer enough to just pay attention to the power and the corresponding lamp base. Power As with the...

Does dim light really cause myopia? I believe that many people are paying attention to this problem, especially those with children at home, who will encounter these problems more or less in students and life, but don't worry, Sunmory will tell you what truly it is? If you read a book under dim light or read a novel with a flashlight while hiding under the covers after turning off the lights, your parents may warn you that doing so will damage your eyesight. A quick search on the Internet, you will find that this is fabricated. And when you keep track of it and see if there is any relevant evidence, things become more complicated. Our eyes are very cleverly designed to help us adapt to different lighting. When the light is weak, our pupils will expand to allow more light to gather on the retina, so that we can see more clearly. If you just wake up in a dark room, at first it is pitch black before your eyes, but after a while, you will be able to see more clearly, this is why your ...

As an indispensable material for modern house and commercial lighting, lamps and lanterns have more than just lighting functions. Configure different light sources for it, you can create different lighting and lighting effects. So, what are the common types of light sources for lighting fixtures? What are the advantages and disadvantages of different lighting sources? What different spatial occasions are each suitable for? In the future, SUNMORY will count down the classification and characteristics of home lighting sources for you. First of all, we need to know some key parameters about the light source of the lamp Luminous flux: The total amount of light emitted by the light source per unit of time. Generally, the greater the power, the higher the luminous efficiency and the higher the luminous flux. Color temperature: When the color of the light emitted by the light source is the same as the color radiated by the black body at a certain temperature, the temperature of the black bo...
