The smart home products on the market are endless, and new ideas are emerging. Among them, the working principle of intelligent lighting is rich and diverse, the technology is relatively mature, and the production cost is relatively low, thus becoming a high-profile link in smart home. At present, the smart lighting products on the market are not only rich in variety, but also have a large number of consumer groups. Intelligent lighting, or control of the luminaire through intelligent switches, breaks through the limitations of traditional manual switches during use; or opens the lighting source through sound, remote control, human body sensing, etc., providing consumers with a more convenient and more user-friendly home. service.
First, remote lighting
Remote lighting is a simple and convenient way to control lighting through radio signals. With the maturity of technology, digital wireless remote control technology has replaced traditional mechanical manual switches, and has gradually become a trend sought by modern people.
The remote control switch is equipped with a remote control for the lamp
Remote control switches usually have two remote control methods: one is to use the remote control switch of the mobile phone client, and the other is to be equipped with a switch socket and a transmitter when purchasing. In comparison, the latter technology is relatively low in cost and the finished product is relatively inexpensive. It consists of a movable remote transmitter and a switch receiver fixed on the wall. All functions can be operated directly on the wall switch or remotely controlled by the remote control, which greatly facilitates the user and controls the lamp like It is as easy to change the TV with the remote control.
The remote control switch generally adopts wireless digital identification technology, and each switch operates independently and does not interfere with each other. Some people may worry that the direction in which the remote is pointing is too difficult to pinpoint and may affect receiver sensing. In fact, this kind of worry is not necessary. Because the wireless RF remote control has no directionality, the signal can pass through the wall and has no radiation. The buttons can be controlled at any corner of the room. Others think that replacing the switch seems too cumbersome, but the actual operation is very simple, the switch and the luminaire can be simply connected during installation, and will not damage the overall layout of the room.
LED remote control lights and line modification say goodbye
At present, there are many types of intelligent LED remote control lights, including bedroom ceiling lamps, living room crystal lamps, lamp belts, light bulbs, and lamps. On the controller is also divided into mobile phones or equipped with transmitter control, LED remote control lights further solve many users are reluctant to reinstall the socket switch, do not want to modify the circuit line and other issues.
Taking the remote control bulb as an example, the LED remote control lamp has a built-in high-power LED lamp bead, and the lamp holder is equipped with a wireless receiving module, and a switch module with an encoder and a control light is connected. Compared with the remote control switch, the remote control lamp directly installs the receiver in the lamp holder, eliminating the trouble of line modification. The common remote control distance of the LED lamp controlled by the transmitter is about 10 meters, and the brand remote control lamp can reach more than 15 meters. This control distance can fully meet the needs of ordinary families. The remote control light controlled by the mobile APP is a breakthrough in the distance limit, and the use of the luminaire can be viewed anytime and anywhere. When there are too many lamps in the house or in the store, the lamps can be grouped and managed, and the same device can be used to regulate a group of lamps.
Second, induction lighting
Human body induction is also called infrared induction. The human body has a constant body temperature, generally around 37 degrees, so it emits infrared light of a specific wavelength, and human body induction illumination controls the illumination of the lamp by capturing this specific wavelength of infrared light.
Unlike the remote control switch, which can be controlled by the button at any time, the most important feature of the infrared human body sensor switch is the delayed illumination. Because the human body can't stand in front of the switch to keep the light on, it can't turn off the light once it leaves the infrared sensing range. How to extinguish it after turning on the light? This requires time-lapse lighting to control the lighting time. During the delay time period, if someone is active within the effective sensing range, the switch will continue to be turned on. After the person leaves, the delay will automatically turn off the load, realizing the intelligent control function of “the person comes to light and the person goes outâ€. Another feature of the infrared sensor switch is the application of photosensitive control.
The switch automatically meters the light and does not sense when the light is strong. It usually works when the outside light is below 15 lumens, but some of the all-weather infrared sensor lights for the basement or garage will not increase the light control.
It should be noted that the false alarm rate of the human body sensor switch has a great relationship with the installation position and installation method. Therefore, when installing the human body sensor switch, it should be away from heating, air conditioners, refrigerators, stoves, etc., and the switch should not be straight to the window to prevent False alarms caused by disturbances in the flow of hot air outside the window and movement of people.
Human body induction cabinet light brightness, high energy consumption, low temperature resistance
Many people think that the human body induction lamp is only suitable for special areas such as corridors and balconies. In fact, with the development of technology, the infrared sensing distance and sensing angle of the human body induction lamp are constantly increasing. Due to its high sensitivity and time-delayed lighting characteristics, many families choose to install human body sensing in baby bedsides, cabinets and other places. light. The USB charging cabinet light is installed in the cabinet. Once someone enters the sensing range, the special sensor detects the change caused by the infrared spectrum of the human body, and the lighting source is automatically turned on. If the person does not leave and continues to move, the light will remain bright and treat people. It will automatically close after leaving.
Some cabinet lights are available in warm white and cold light, suitable for lighting needs in different seasons. Under the same power, the LED light source not only has stronger brightness than ordinary fluorescent lamps, but also has low power consumption and high temperature resistance, which is very energy-saving. The LED light source has small light decay, high color rendering index, no harmful metal in the lamp bead, and the waste is easy to be recycled and processed, which is very environmentally friendly.
