On October 21, 1879, Edison used a cotton wire with a diameter of 0.025 cm as a filament for testing. Prior to this, he had tested 1,600 different heat-resistant materials such as tantalum, nickel, platinum, and platinum-rhodium alloys, all of which failed. These seemingly hard materials did not resist the heat generated by the continuous work of electricity. , or break or melt.
This time, Edison carefully turned on the power, held his breath and began to observe the record. The luminosity of the carbonized cotton filament is bright and stable, equivalent to the illumination of four candles. Time passed by, one hour, two hours... it was 45 hours, which was a miracle at the time.
Today, people are no longer satisfied with the lighting, the city's neon is dressed as a beautiful scenery, the world's skyscrapers can not wait to be gorgeous lights at night, and there are many new art with light as a form of expression.
But these distances seem to be very far away from ordinary people. When we walked into the house, the light bulbs that were hanging above our heads were still dumb, and it was a bit boring. This gave birth to intelligent lighting. You may have heard of the concept of smart lighting, but do you know how smart wisdom lighting is? Smart lighting refers to the use of wireless communication data transmission technology to integrate mobile phones, sensors, IoT devices, and smart switch lights. An emerging product of intelligent control of lighting equipment. Simply put, smart lighting is a luminaire with ideas.
For example, when you walk into the corridor of the community building at night, you say: "Bright." The light is on. This is not a smart lighting. This is mostly a voice-activated light. You said: "Destroy." The light is off, this is the wisdom of illumination. It can tell what you are saying, not simply capture what you are making. Of course, just having this "wisdom" is not enough.
The lighting system consisting of a microprocessor, a wireless transceiver, a motion sensor and a light sensor can accurately determine whether there is someone in the room and whether it is moving. By coordinating the algorithms performed by the sensors and processors installed on the lights, you don't have to talk, the lights will automatically light up. The light won't light up the entire bedroom, but it will only surround you like a searchlight, so it won't affect the family you are sleeping in.
Or, you can also set the action according to your own preferences, and control the color change and strength of the lamp through gestures. For example, when the index finger and the thumb touch gently, the light will light up, and when the fist is pressed, the light will go out. Turning off the lights every night is like playing a sci-fi blockbuster. Isn't it cool?
This is not enough. You can also set parameters for the light bulb. When you feel that the reading light at night is too glaring, you can verbally manipulate the brightness of the light. The controller in the light bulb will collect and record your settings, and wait until the next time you use it. Adjust to the most comfortable brightness. If you have used a period of wisdom lighting, then the latter will integrate your life rules and habits, automatically adjust the color and color temperature of light according to different time periods, and synchronize with the natural physiological rhythm of the human body.
This is still not enough. Smart lighting can also monitor the surrounding temperature and humidity, and will work with a networked smart home, such as an electric heater or humidifier, to adjust the room to the optimum temperature and humidity. Traditionally, people think that the illumination of the light is harmful to the human body, and the wisdom lighting can pull back a city. It can not only illuminate but also maintain health.
Not only do you need smart lighting at home, you still need to drive out at night.
Many people have the experience of driving a night train. The street lights on both sides of the road bring great convenience to our travel and guarantee the safety of our travel. However, in the early hours of the morning, the traffic on the road is very small. It may not be possible to pass ten vehicles in a few hours, which will inevitably result in waste of energy. However, it is impossible to extinguish the street lamps. Energy waste is certainly valuable, and people's driving safety is higher. Is there a way to solve the problem? When there is a vehicle, the street light is on. When there is no vehicle, the street light is automatically extinguished.
The answer is smart lighting. We can install monitoring at each intersection, install a controller for each streetlight, monitor and observe the road to the car, send a signal to the controller of the street lamp, and illuminate it. When the passing of the train is detected, and the vehicle is not coming in, the street light will be extinguished. In addition, it is also possible to adjust the brightness of the street lights according to the changes in traffic flow and pedestrians, and to save energy on the basis of ensuring the maximum illumination.
Arthur Clark, who is also known as the three sci-fi novelists of the 20th century, with Isaac Asimov and Robert Heinlein, has a famous Clark's three basic laws, one of which is: any advanced technology, At first glance, it is no different from magic. Showing voice-activated lights to people 100 years ago, they will definitely think it is magic.
Our luck is that the speed of technology development is getting faster and faster, and our ability to accept new things is getting stronger and stronger. Therefore, when the wisdom lighting really enters the life of each of us, we will not exclaim magic, we are early Be prepared to meet the wisdom of lighting, let the wisdom come even more fierce.

The Zinc Oxide Type Surge Arrester is the latest advanced over-voltage protector for distribution line and power stationdevice. Incorporated with zinc oxide and other metal oxide as the core resistor disc, the volt-ampere characteristics and thethrough-current capability of the resistor disc are improved drastically compared with the conventional SiC type surge arrester.
Under nominal operating voltage, the current through the surge arrester is only about micro-ampere grade. When the surgearrester experiences an over-voltage, the resistor disc with excellent non-inear characteristics will increase the curent throughthe surge arrester to several thousand amperes instantaneously, The surge arrester is in a conducting state and then will releasethe over-voltage energy to the earth and thereby protects power distribution / transmission device against the impact of over voltage.
