Technology has changed life. The development of science and technology can make people’s lives more convenient. With the advancement of science and technology and the development of people’s lives, people’s pursuit of lights is not only the role of lighting but also new requirements for lights. In order to meet people’s needs, smart LED light is produced. The original intention of the production of smart LED lights is also to facilitate people’s lives. Different companies have different ideas on smart LED lights. They give smart LED lights different characteristics. Some LED lights change colors according to their needs; some LED lights have different sensors, let them follow this The environment changes to automatically switch the lights; some LED lights can be connected to the gateway so that it can be remotely controlled. As more functions of smart LED lights are given, they can be used on more occasions, benefiting more people.
Brief introduction of smart LED lights
Smart LED lights refer to the addition of some smart modules on the basis of traditional LEDs to make the use of LED lights intelligent. Smart LEDs generally extend network protocols (WiFi, Bluetooth, ZigBee) to make them networkable, connect to related platforms, and realize remote control. In addition to the main feature of networking, different smart LED lights will give different functions. For example, some smart LED voice control functions, some smart lights have a color change function, some smart lights will automatically change the switch state according to demand, some can be switched on and off regularly, and some can remind strangers to enter the house. The configuration of the sensor will greatly expand the intelligence of the smart light, which can be used in more scenes.
With the rapid development of Internet of Things technology, smart home has become an important part of the Internet of Things industry, and has become the target field of various companies. Smart LEDs as important members of smart homes have also developed rapidly along with the rapid development of smart homes. With the popularity of the Internet of Things, smart LED lights will be used more and more.
Classification of smart LED lights
- Classification according to lighting status
According to the lighting status of smart LEDs, it is divided into three categories: dual-state smart LED lights and three-state smart LED lights;
Two-state smart LED light
Two-state smart LED lights are divided into:
- On and off type;
- High-brightness and low-brightness type.
Features and applications of dual-state smart LED lights:
Dual-state (on and off) smart LED lights:
During the day or when the ambient illuminance is high, the LED lights will not trigger. At night or when the ambient illuminance is low, the lights will turn on when people come. When people leave or standstill after a delay of 30-60 seconds, the LED lights will go out. It is suitable for corridors and stairways.
Two-state (high-brightness, low-brightness type) smart LED lights:
Work 24 hours, people come to highlight when people leave or stand still and turn to low-brightness lighting after a delay of 30-60 seconds, suitable for corridors, stairways and underground parking lots and other public places, especially suitable for dark The corridors and stairways can ensure basic lighting and make people feel safe. When no one is walking, low-brightness lighting can save electricity.
Three-state smart LED light
There are three states of the three-state smart light: off, low on, and high on.
Features and applications of three-state smart LED lights:
During the day, the LED is in the off state because the solar illuminance is higher than the turn-on light illuminance threshold. In the evening, when the day’s illuminance is lower than the turn-on light illuminance threshold, the LED light is automatically turned on.
At night, after the LED lights are turned on, people come and illuminate with high brightness. After a delay of 30-60 seconds after the person leaves or stays still, the LED lights switch to power operation, low brightness lighting, achieve on-demand lighting, intelligent energy saving.
At dawn the next day, when the day’s illuminance is higher than the light-off illuminance threshold, the LED lights are automatically turned off, mainly used in road lights and garden lights.
- According to the sensing method, smart LED lights are divided into:
- The radar sensor smart LED light, which can sense moving objects, has high sensitivity and long detection distance, but it can be falsely triggered by swaying branches when the wind blows.
- Infrared sensor smart LED lights can sense moving people and large animals, but in summer the ambient temperature is high and the sensitivity is low.
- Sound induction smart LED light, sound induction, as long as the sound is greater than 70 decibels, it will be triggered. If the environment is noisy, such as near the street, the sound control light will be triggered continuously.
- The image detection smart LED light can distinguish moving objects by detecting changes in the image. It has high sensitivity and long detection distance. It is suitable for tunnel entrances, highways, and expressways, and detects long-distance, fast-moving objects, such as high-speed motion. Cars and other objects.
- Classification according to whether it is networked or not:
Independent smart lights are not connected to the network and will sense changes in the environment according to their own sensors. When the changes in the environment reach a certain value, the LED lights will automatically respond, otherwise the sound-controlled lights commonly used in corridors are independent.
Smart LED lights are networked and communicate with each other to realize telemetry and remote control. Many LED lights that can be controlled by mobile phones are networked.
Advantages of Smart LED lights
The light energy conversion rate of LED light is higher than that of incandescent lamps and fluorescent lamps in daily use. LED light with the same power produces more lumens, brighter light, and farther illumination. So we can use less powerful LED lights to light up the room. The LED light produces less heat, reduces the loss of energy, energy saving, environmental protection.
The smart LED light can be remotely controlled by the mobile phone, and the timing switch can be set for the smart light. Led smart lights are connected to gateways, which are used to connect with relevant platforms. Mobile phones can transmit relevant instructions through these platforms so that the smart lights can receive the information and respond according to the information.
Light color change
The advantages of smart light can change the light intensity, can emit weak light, can also emit strong light, some can adjust the color of LED light according to the combination of LED bulbs, can adjust a lot of colors according to the demand.
The color of LED light is not needed when the current changes. The diode and the core part are composed of P-shaped semiconductor and n-shaped semiconductor, and there is electrodeposition between the two semiconductors. The structure of P-shaped semiconductor is different from that of n-shaped semiconductor, the number of electrons outside the atom is different, and the attraction to electrons is different. When the forward voltage is applied, the carriers will release the extra electrons in the form of light. The intensity of light varies with the voltage.
By changing the material of led through chemical modification, we can control the color of light by the current. For example, when the current is high, it is green LED. With the decrease of current, it is yellow, orange, and red in turn. The three primary colors of light are red, green, and blue. A smart LED light is composed of many small LEDs. Many colors can be combined by changing the proportion of red, green, and blue in the small LEDs.
MOKOlight smart LED light is used to control the switch with the smartphone. This kind of smart LED light can also remotely control the status change of LED light through the app, which is simple to operate and convenient to use.
Uses of smart LED lights
Use LED smart lights in the garage
It is troublesome to get a car in and out of the garage. When driving back from the outside, driving into the garage, you need to get out of the car and turn on the lights, then go back in the car and drive in. When you go out, you need to get off and turn off the lights. Using smart LED lights, the mobile phone can control the lights on and off without getting out of the car to turn the lights on and off. At the same time, some sensors can be added to the smart lights, such as turning on the lights when there is a car’s sound, and turning off the lights when not.
Home use LED smart lights
Home LED smart lights can be controlled remotely. If you forget to turn off the lights, you can turn off the lights remotely. You can also add some brightness sensors. The sleeping mode can be set in the bedroom, and the user can sleep under the appropriate light. The toilet is equipped with voice-activated LED lights, so there is no need to look for lights when going to the toilet at night. When going on vacation, a thief enters the house at night. If you turn off the lights remotely, you can protect your property.
Use LED smart lights in the office environment
Using smart lights in the office environment, you can remotely control the lights on and off. In addition to the company, you can also turn off the lights in the office without running back. You can also add some special functions, for example, you can add some infrared sensors, go back to the company to pick up things at night, and turn on the lights wherever you go. You don’t need to turn on the lights in the entire office. This is a cool thing. Can save electricity.
Human beings are becoming more and more individualized, and the pursuit of life is bizarre. The development of LED smart lights can meet people’s diversified needs for light. People can set their favorite scene lighting effects according to their own lighting needs (such as color, temperature, brightness, and direction, etc.). The convenient smartphone also provides a more humane intelligent control channel to create different indoor intelligent lighting effects. . From then on, people can choose and control the brightness, gray, and color changes of light in different spaces and times according to their requirements, scene conditions, and different understandings of the environment and life, and simulate various light environments to guide and improve emotions. , Reflecting a more humane lighting environment, and at the same time, interactive social sharing of electricity and scenarios also meet the inner needs of human socialization, and will surely promote the intelligentization of energy-saving light bulbs.
