Lamps with motion sensors are one of the most popular lighting devices installed in residential and commercial premises. Their feature is a built-in sensor that responds to movement and automatically turns on lighting. The luminaires are turned off automatically when there is no movement in the room during a certain time period set by the user.
Principle of operation
Reducing the cost of electricity provoked by the constant operation of lighting devices can be done in the simplest way - by installing LED ceiling lights with a motion sensor.
The principle of operation of lighting devices is based on the signal projected by the sensor when an object appears in its field of action. If there is no movement, the light will automatically turn off.
Features of fixtures
High-quality ceiling lights with a motion sensor have a number of features:
- Do not respond to animals.
- Do not work repeatedly when another person appears in the room.
- They are disconnected only after all people leave the room.
- You can adjust the time interval, which should be enough to cover a person's passage room.
- A light threshold limits lamp activation in the daytime.
Lamps with motion sensors are of two types: wired and wireless. They can be equipped with a sensor that regulates the level of lighting. In the daytime, it blocks the inclusion of the lamp, can also change the level of its brightness depending on natural light.
Fixture
The design of the lighting device depends on its purpose. An alternative to fluorescent lamps and incandescent lamps are LED lamps.
The design of the device consists of an electronic control unit, a special optical device and an LED electronic device. All elements are enclosed in a common housing.
There are original designs: the cartridge can be equipped with a motion sensor and installed in a lighting fixture instead of the standard one, acting as an adapter.
Specifications
Wall and ceiling lamps with a motion sensor have the following parameters:
- Power. Affects power consumption and light levels.
- Colour temperature. The lamp can shine with warm yellow or white cold light depending on the specified light stream.
- Dispersion angle.
- Working temperature. LEDs, unlike other lamps, almost do not heat up.
- Voltage. Diodes are resistant to voltage surges.
- Degree of protection against moisture and dust.
Sensor Parameters
When choosing a ceiling lamp with a motion sensor for an apartment, the characteristics of the built-in sensor must be taken into account:
- Sensitivity. Affects range.
- Viewing angle. When placing the lamp in a corner of a rectangular room, an angle of 90 degrees is enough for efficient operation.
- Climatic equipment. Resistance to high and low temperatures.
- Power load.
- Working temperature range.
Outdoor luminaires with a motion sensor must have a high level of protection against dust, moisture, high and low temperatures. Devices that meet the above requirements can be operated outdoors.
Installation and setup
The complete set of a ceiling lamp with a motion sensor includes an instruction that contains a detailed diagram of the installation and connection of a lighting device. The procedure does not require a call from specialists.
The phased installation of the lamp is as follows:
- The location of the sensor is determined taking into account the location of the doors and the routes of movement of people living in the house.
- In parallel, it is desirable to connect a standard key switch. In the event of power surges, the touch switch indicator may fail. A key switch allows you to use lights as a regular chandelier.
- A lighting fixture with a sensor is connected to the contacts of the switch and the industrial network cable. The wire-phase from the sensor is brought to the switch. You cannot directly connect the lamp to the network phase. If necessary, grounding is installed.
- All wires must be insulated.
- The sensor is being configured: the time for turning off the light in the absence of movement is set. The manufacturer provides relevant recommendations in the instructions.
A battery-powered self-contained ceiling lamp with a motion sensor is mounted in the same way. The industrial network is replaced by battery terminals.
Lighting devices with motion sensors save energy and simplify the use of lamps by children and the elderly thanks to automatic switching on.
Benefits
Consumers note the following advantages of ceiling lights with a motion sensor:
- Save energy and pay for it. No need to remember that the lights must be turned off.
- Lamps are suitable for any type of lamp.
- Light intensity and duration can be adjusted.
- Wide model range and diverse design.
disadvantages
- High sensitivity of the sensors, because of which they respond to the movements of small animals and birds, overload voltage.
- If there is no turn-off delay, inconvenience may occur if the lights are turned off due to lack of movement.
- Changes to the wiring of an apartment or house are required.
Wall and ceiling lights with a motion sensor are popular because of their convenience, reliability, long life and low power consumption. Reducing electricity consumption can save on utility bills. Automatic switching on and off of lighting fixtures is most convenient in houses where young children and elderly people live - you do not need to turn off the lights in the rooms yourself, which also saves electricity.
