Cost-effective and convenient modules are widely used for electric lighting of rooms, private courtyards, gardens, parks, parking lots and construction sites. A light bulb with a motion sensor gives a bright light beam that goes in a certain direction or diffuses over the area. At the same time, the detector detects moving people or animals. If necessary, the annunciator automatically triggers an alarm or algorithm of specified actions.
Purpose and principle of operation
The touch device detects the movement of the object in the field of reach and the lighting zone. The luminaire does not independently respond to the circumstances, but turns on or stops working on a signal from the detector.
A predefined function on the relay is activated when detecting motor activity in the controlled area. The sensor gives a signal to turn on the lamp, a change in the power of optical radiation.
Motion detectors are:
- infrared passive - make up more than 50% of cases of use;
- ultrasonic active sensors, microwave models;
- combined types, including infrared and photovoltaic cells.
The interaction of the sensor and the lamp is pre-programmed. A built-in dimmer is used - a regulator of the saturation of the light emitted by LEDs or incandescent lamps.
Modules with infrared sensors are popular, which are activated when the thermal background in the control area changes, have a large inspection area, safe radiation and precise settings.
Microwave and ultrasound models are active options, receive radiation of a certain length, do not respond to atmospheric influences. Adverse effects on animals, have a limited coverage area.
Twilight switches give a signal about the output of the light flux when changing the brightness of the environment. Automation stops the lamp at dawn. Components can be integrated into any type of LED lamp.
Design features
The body of the device is made in the form of a ceiling, lantern, chandelier. Compact modules are conveniently mounted in different places.
Functional devices are equipped with lamps:
- halogen;
- luminescent;
- LED light.
The model incorporates protection systems against overload, circuit, overheating. The device always has a lighting element and a sensing sensor.
Modules depending on the use case:
- portable - put in the right place, work on removable batteries, there is a power limit;
- stationary - requires electricity, the disadvantage is the lack of mobility.
The remote motor sensor contacts the lamp via wire. In another case, the sensor element and the lamp are combined in one unit, then the detector is called built-in.
Scope of application
Light bulbs with a motion detector are installed in places where a person is short-lived and infrequent. Examples include house entrances, stairwells, corridors. The second direction of use is the economic and industrial sphere, where the modules operate at night. Devices are used in street lamps so that the lighting is switched on in the presence of a moving object.
Lamps with sensors are used in various backlight options:
- white with cold rays mounted on lampposts;
- white with neutral radiation is placed in offices and on industrial sites;
- warm yellow change incandescent lamps in houses and apartments;
- other colors are used for decoration in public entertainment centers.
Failures are sometimes observed if the modules are located close to fan heaters, air conditioners. It is not recommended to place the devices in the corner due to the restriction of the inspection area; it is better to mount them in the center of the ceiling.
Features of installation and configuration
A parallel, serial and combined circuit is suitable for connecting the module. In the first case, the light is turned on by the sensor signal and when using the toggle switch. In the second circuit, the lamp only functions when the circuit is closed by a switch. In the combined method, an additional light beam arises from the detector signal, but the main source operates from a switch.
Installation of a lamp with a motion sensor for the house, which is removed at a distance:
- Find a sensor mount with good visibility
- mount a stand on the wall at a height of up to 2.4 meters;
- open the hood of the terminal box and the sensor, strip the contacts and connect 220 V via zero and phase, isolate the connections;
- connect the light bulb.
It is important not to mix the phasing, if this happens, change the wires in places. Similarly connect the cable with the plug.
Installing Wireless Lamps
The housing contains an ultrasonic detector, a lamp, a power control sensor. At the preparation stage, the seals are placed in the openings of the housing where the wires will be introduced. Before work, disconnect the installation network.
Further actions:
- the power cable is pulled into the lamp box through the hole with a sealant, shortened if necessary;
- the wire is laid through the mounting holes of the housing and is grounded on the ceiling or wall;
- if the case is made of dielectric material, grounding is not performed;
- the supply wire is exempted from the braid, phase and zero wires are used to connect.
There are special terminals for connection in which the cable is fixed with a screwdriver. In the complex there is one free contact where you can connect additional lights, fans or other elements of the system.
Advantages and disadvantages of a lamp with a motion sensor
Tracking modules are distinguished by ease of use, when you turn on automatic mode, there is no need for manual adjustment. Universal devices are equipped with various types of fixtures, which expands the scope.
The frequency of operation of the lighting-tracking units saves energy (up to 50 - 70%) and extends the service life. Lamps with a sensor are equipped with an alarm system and protect the room or area from uninvited guests. A good solution is to place the lamp above the input opening and set it up in a specific operating mode.
Tracking modules are unsuitable for rooms where people are constantly moving. The sensor notices only movement directed perpendicular to its central axis.
Top manufacturers
