Devices with motion sensors (DD) increase the level of comfort in residential and office spaces. In addition, they have an equally important task: to save energy.
Led LED lamps with motion sensors are devices of the modern generation that are used in everyday life, on the street and in production. These are simple products for lighting rooms, characterized by a sensitive sensor that "responds" to movement, temperature fluctuations, air composition or wave range fluctuations. This sensor is responsible for supplying and turning off the light.
Application area
The areas in which Led lamps with a motion sensor are used are very diverse. They are installed in those places where people stay infrequently:
- halls;
- landings;
- corridors;
- near the houses.
In production, warehouses and industrial enterprises, lamps are installed in the same places that need only temporary lighting.
Types of lighting
The use of such devices also depends on the type of radiation. So there are three types of lighting:
- white (warm) - used for production and offices;
- white (cold) - used for the street;
- infrared - used for poultry livestock complexes.
The principle of operation of the device
The LED sensor is designed in accordance with the manufacturer’s idea, so DD can be connected to luminaires of this kind. These sensors are responsible for automatically turning on / off the light while driving. A large number of lamps are already sold with built-in DD.
Many types of motion sensors have been developed that differ only in the principles of their action.
Infrared
Most often, such Led lamps with a motion sensor are used in residential and industrial premises. Their action is based on capturing fluctuations in ambient temperature. Living objects emit certain waves that can heat nearby surfaces and objects. Therefore, this sensor is turned on by the presence of a person in the area controlled by him.
This model has a drawback: the sensor primarily responds to temperature changes caused by human movement. If the object is in range for a long time, the air temperature will become the same, and the sensor will perceive it as normal. After that, he will give a sign to turn off the light.
Ultrasonic
They are used most often on the street. The sensor picks up ultrasonic waves with a frequency of 20 to 60 kHz. The waves are reflected from the object, changing the wave frequency, meeting it in its path - these are the sensor that responds to vibrations, giving a sign that the light is on.
Microwave
The method of operation is the same as that of ultrasonic sensors, but it does not respond to sound, but to radio waves. These sensors are used for street and indoor use.
Combined
These are more sensitive devices, the principle of which is based on the simultaneous operation of several types of sensors. Most often, it is a photo relay in combination with infrared DD.
Advantages of Led Downlights with Motion Sensor
To determine whether the luminaires with DD are beneficial or not, you need to get acquainted with the opinions of people who have had experience with these devices. In the reviews, consumers pointed out some of the advantages of such lamps:
- Big savings in energy saving;
- tolerance of voltage drops;
- long service life;
- simple installation;
- the ability to control the sensitivity of the sensors.
Disadvantages of housing and communal services lamps with a Led motion sensor were not revealed by users.
Installation and Connection
Installation of a Led linear lamp with a motion sensor contains several successive steps:
- Turn off the power supply in the installation area.
- Insert the seal into the holes that are intended for the wires. The sealant is part of a kit with a lamp.
- Pull the cable through the seal.
- Measure the length of the wire from the seal to the lamp terminals.
- Remove excess wire.
- Fix the lamp housing on the desired surface through special holes. It is necessary to use self-tapping screws or dowel-nails.
- Remove the braid from the cable.
- Connect the wire to the terminals.
- Screw in light bulb.
- Install a shade on it.
- Configure DD according to the instructions for use.
The choice of location of the lamp depends on the layout of the room and its purpose. In this case, the type of lamp is also taken into account:
- Wall. They are located in the highest part of the space. In the interior, pantries, garages, walk-in closets - the optimal location of the lamp - directly opposite the door.
- Ceiling. Devices are recommended to be mounted in the center of the room.
Most often, Led lights with a motion sensor are universal. They can be located on any necessary surfaces.
Conclusion
Lamps with such sensors are extremely useful and necessary devices: they help to save energy and save from the hassle of constantly turning on and off the light in places with irregular traffic, and in rarely visited rooms.
