How smart is smart lighting?

On October 21, 1879, Edison used a carbonized cotton thread with a diameter of 0.025 cm as a filament for experiments. The test was successful, and the filament was lit for 45 hours, which was already a miracle at the time.

　　 Today, people are no longer satisfied with lighting. The neon of the city is dressed up as a beautiful landscape, and there are many emerging art in the form of light.

　　 But these seem to be very far away from our ordinary people. When we walked into the house, the dumb light bulb hanging above us was a bit boring. This gave birth to smart lighting.

　　Smart lighting refers to an emerging product that uses wireless communication data transmission technology to integrate mobile phones, sensors, IoT devices, and smart switch lights to achieve intelligent control of lighting equipment. Simply put, smart lighting is a lamp with ideas.

　　 For example, when you walk into the corridor of a residential building at night, you say: 'On.' The light turns on. This is not smart lighting, but at most it is a voice-controlled light. You say: 'Go off.' The light goes out. This is smart lighting. It can distinguish what you are saying, rather than simply capturing what you are saying.

　　 The lighting system composed of a microprocessor, a wireless receiving and sending device, a motion sensor and a light sensor can accurately determine whether there are people in the room and whether they are moving. Through the collaborative calculation of the algorithm carried out by the sensor and the processor installed on the electric light, you don't need to speak, the light will automatically turn on. The light does not light up the entire bedroom, but only surrounds you like a searchlight, so that it will not affect your sleeping family.

　　 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, the light will turn on when the index finger and thumb are touched, and the light will go out when you make a fist. Turning the lights on and off every night is like acting in a sci-fi blockbuster, isn't it cool?

　　 This is not enough. You can also set parameters for the bulb. When you think the light is too dazzling for reading at night, you can verbally manipulate the brightness of the light. The controller in the bulb will collect and record your settings. When you use it next time, it will automatically Adjust to the most comfortable brightness. If you have used smart lighting for a period of time, the latter will integrate your life rules and habits, automatically adjust the color and color temperature of the 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 cooperate with networked smart homes, such as electric heaters or humidifiers, to adjust the room to the most suitable temperature and humidity for the human body. In the traditional sense, people think that the illumination of light is harmful to the human body, while smart lighting can bring back a city. It can not only illuminate, but also maintain health.

　　 Not only do you need smart lighting at home, you still need it when you drive out at night.

　　 Many people have the experience of driving at night, and the street lights on both sides of the road have brought great convenience to our travel. However, as soon as the early morning passes, there are very few vehicles on the road, and it may not pass ten vehicles in a few hours, which will inevitably cause a waste of energy. Is there a way to solve the problem-when there is a vehicle, the street light is on, and when there is no vehicle, the street light is automatically turned off?

　　 The answer is smart lighting. We can install monitoring at every intersection, install a controller at each street light, monitor and observe the traffic on the road, and send a signal to the street light controller to light it. When a passing vehicle is detected but there is no incoming vehicle, the street light will be turned off. In addition, the brightness of street lights can be adjusted according to changes in traffic and pedestrians, and energy can be saved to the greatest extent on the basis of ensuring lighting.
