Motion Sensor Assignment
The sensor element has the function of determining the fact of movement of any object within reach and controlling the lighting. The lamp itself has nothing to do with responding to certain circumstances, but after the signal from the sensor comes in, it turns on or off.
As soon as an action is noticed in the coverage area, the previously embedded function on the relay is activated. Not only the “turn on” command can be given, but also a signal to change a parameter such as power. For a light bulb with a motion sensor and dimmer it is possible to adjust the indicators of illumination by time of day
The interaction of the sensor, dimmer and lamp, as well as the time delay for switching on depend on the previously programmed system settings. The last action is to trigger the command to activate the lamp after a set period of time, as a result of which it is possible to save energy.
Lamps, supplemented by a built-in motion sensor, is most often installed in residential premises, offices, and hallways. They are also used for smart outdoor lighting.
The lamp with a motion sensor is the best option for a lighting device in the stairwell. It will be included only when a person appears in the front door or on the staircase.
A person, due to his inherent inattention, can leave the light on, and this results in additional expenses. A lamp that turns on after a room becomes empty simply solves this problem.
Types of lamps with motion detection
Depending on how the energy source is used, the lamps may be:
- Stationary. They function only when connected to the network. You can not install them anywhere.
- Portable. These are autonomous devices running on replaceable batteries. The advantage is the lack of connection with the wires, but there is a limit on power.
As an energy supplier, not only a traditional electricity grid can be used. There are lamps equipped with solar panels with battery. Work with this power can only LED lamps, because they need a minimum of electricity.
According to the method of connection, there are two options: in the first of them, the motion sensor is connected to the lamp with the help of a wire and it is called remote.
Led lamp equipped with a sensor type DD. Powered by batteries. Thanks to mobility, it can be applied anywhere.
In the second, the sensor element and the lamp are a single design, the sensor in this case is called built-in. The reading element can be both infrared and ultrasound, based on microwave radiation.
Infrared Detector Lamp
The most popular are the devices, supplemented by infrared detectors. They are activated when the thermal characteristics change in the control zone. Such IR sensors are referred to as passive. These devices have a large pickup angle, high precision settings, and safe radiation.
Lamps, equipped with motion sensors - an excellent and competent solution for both modern lighting of housing, outbuildings, stairs, local area, and for use in large scales
Luminaires with passive IR detectors are intended for internal use only. Their use for illumination of courtyards and streets is impossible due to poor resistance to temperature changes. They take them down.
Ultrasound and microwave options
This type of motion sensors are based on the principle of action to the active. They have a general principle of operation - radiation and acceptance of waves of a specific length. Luminaires with sensors that respond to ultrasonic frequencies are universal. For them, weathering is not terrible, so they are suitable both for installation in the house, and from the outside.
But there are drawbacks to ultrasonic sensors, and the main one is the negative impact on animals that can pick up radiation. To this can be added a limited coverage area, low accuracy.
Sensors based on microwave radiation work due to the propagation of magnetoelectric waves at a frequency of more than 5 GHz. They equip them lamps installed in the economic, industrial premises. Here their action is designed for the passage of partitions and walls.
Expensive models of lamps with sensors that react to movement, complete with control panels. Their design includes several reading devices that control and to some extent overlap the zones of influence of each other.
The lamp of the new generation with two motion sensors - IR and ultrasound. At the time of their simultaneous operation, the lamp turns on
Luminaires with sensors are designed to be powered by a 220-volt alternating current source. The maximum power is up to 2 kW, although there are devices operating from 12 V.
Design features of the lamp
The difference between the bulb with the motion sensor and the most common is the presence of a reactive element. The shell is made in the form of a lantern, a floor lamp, a chandelier or a ceiling. In tandem with the motion detector used different versions of lamps: LED, fluorescent, halogen.
The most successful is a tandem with LED lamp. These functional devices are compact, convenient to install. LED models sometimes additionally complete an independent control relay with a controller. Due to the presence of these options, you can control both the brightness and the parameters of the glow.
In the photo is a lamp with a motion sensor Lemanso lm650. Apply a device for lighting any premises. Installation is extremely simple — similar to plugging in a conventional light bulb.
In some cases, the circuit includes protective systems that protect against short-circuits, temperature overloads, high voltages. Regardless of the internal configuration, the principle of operation of such lamps is unchanged: the lighting device must have a reading element - a sensor.
Advantages and disadvantages of motion detection lamps
The lamp with an electronic eye has a lot of advantages. These devices are very convenient - when the system goes into automatic mode, there is no need for manual control.
The advantage is the versatility of lamps. They can be equipped with any type of light element, ranging from a simple incandescent lamp to the most modern and economical light bulb.
Manufacturers produce these devices in a large size range. Since they work only periodically, their service life is long. Lamps can be very decorative, so they are often used in landscape design.
In high-quality luminaires with motion detection there are mechanical and electronic levels of adjustment. In the first case, the angle of inclination is meant, and in the second, the luminescence time, the sensor sensitivity
It is possible to connect the alarm system to the lamp with the motion sensor. Such an alliance will help protect the yard from robbers. A successful solution is a lamp with a beam that is configured according to all the rules and is located above the entrance door or in a dark garage. But the main advantage is the efficiency of these lighting devices. They save from 50 to 70% of electricity.
The disadvantages are two features of such lamps. The first is that the sensor is not able to notice movement that has a perpendicular direction in relation to it. The second is for a room where people stay for a long time, such a device is of little use.
Features of the installation of lamps
To connect the lamp, supplemented by a sensor, all schemes used for simple motion detector. There are three types of such schemes.
The first is a parallel connection of the device with the switch. In this situation, the lighting is turned on either due to the detection of a moving object in the area under control, or by means of a switch.
The second is the serial connection of the sensor and the switch. The lamp can function with this type of connection only after the circuit is closed by turning on the switch.
The third is a combined connection. After detecting movement in a controlled area, additional lighting is activated using a sensor.
These wiring diagrams are the simplest. To prevent the sensor from tripping in the daytime, you should purchase a lamp with a motion sensor, supplemented with a light intensity sensor.
The position of the switch does not affect this. The main light source is switched on by a switch.
Installation of the lighting device with motion sensor
Consider the process on the example of a lamp designed for indoor installation. According to its design, it is suitable both for mounting on the ceiling and on the wall. The case contains a conventional lamp, an ultrasonic RF motion sensor, and an ambient light sensor.
The installation technology is simple and consists of six steps:
- At the first stage, the device is prepared for installation. The kit usually includes rubber seals. They are inserted into special holes for cable entry.
- De-energize the installation site by turning off the circuit breaker on the switchboard.
- The power cable is pulled through the seal into the lamp housing. In the presence of excess length, shorten.
- Fix the case on the wall or ceiling through the holes intended for fasteners.
- From the power cable remove the sheath. If the housing material is a dielectric, grounding is not needed. Only the “zero” and “phase” wires are involved, after removing the insulation from their ends - about 7 mm.
- Connect to the appropriate terminals of the wire and fasten with a screwdriver. The phase wire is inserted into the terminal L, and zero - into the terminal N.
A dead terminal, indicated by an L with a stroke, will remain unused. It controls and can be used to connect other lamps, ventilation or other equipment.
Phase conductors are most dangerous when working with wiring. Most likely, for this reason they have the most vivid color. In the diagrams, they are denoted by the symbol L. When there are several phases, a number is added to the letter
The limitation is only the power consumed by these devices. It should not exceed the additional plug-in load specified in the passport.
To determine which of the wires is phase, zero and ground, you need to have the ability to read color coding. Both we and Europe have one standard - IEC 60446 2004.
According to this document, the color is blue, and sometimes blue-white indicates a working zero. The ground wire has a yellow-green color. For marking phase, use the remaining colors - brown, black, red, white, others.
In the presence of old wiring colors may not meet the standard. Here, to determine their affiliation to a particular type, you will have to use a digital multimeter, an indicator screwdriver or a test light.
Remote sensor lamp connection
Installation of a light bulb with a remote motion sensor has its own characteristics.
First install the detector:
- Determine the installation location, providing the best viewing angle.
- A stand, previously removed from the device, is attached to the wall at a height of at least 240 cm.
- Strip the ends of the voltage wires connected to the sensor, removing about 1 cm of insulation from them.
- Open the terminal box cover of the sensor. Inside it are colored wires.
- 220 V is applied to the sensor by connecting the neutral and phase wires to the voltage.
At the end isolate the junction. Next, proceed to the connection of the bulb and sensor. Connect the phase to one end of the lamp, isolate it. The other end is connected to the neutral wire.
Blue wire is zero, usually on the schemes it is denoted by the letter N. The phase wire has a red-brown color and is marked with the symbol L. Ground Wire - Yellow-Green (⊥)
If the phasing during the connection process was accidentally confused, the device will not work, but will remain in working condition. It is necessary to swap the wires elementary. According to the same algorithm, it is possible to connect a wire with a plug to the detector.
Actually the sensor is very easy to manage.
On its case there are three regulators, allowing to change the factory settings:
- Sen - sensor. With it, set the sensitivity of the sensor. Experimentally selected parameters such that the device does not respond to small animals.
- TIME - setting the lamp glow time.
- LUX - day-night adjustment. Adjust so that the lamp turns on with the onset of twilight.
By the response time setting is possible in the range of 0.05 - 15 minutes. The sensor works most effectively at a capture angle from 120 to 360 degrees, on an area of about 20 m.
Lighting devices with sensors turn on or switch to a special mode of operation, both with the help of special and most ordinary switches
In determining the height and angle of inclination, it should be taken into account that the individual infrared sensors may have a dead zone. If the device has a fixed case, and there is no positioning correction, it should be placed in accordance with the technical passport.
Experts do not recommend installing lamps with sensors that react to movement in the corners. The reason is a reduction of the view area.
Malfunctions and false positives can be observed in the case of the installation of such a lighting device near air conditioners, radiators, heat fans. Sometimes the lamp can turn on even when the blades of the room fan rotate from the branches swaying outside the window.
When installing lamps with sensors within an apartment, experts advise placing them in the center of the ceiling. This is the optimal solution to the problem of detecting an object at the required time and at a set distance.
The optimal installation parameters of the lamp with a motion sensor on the wall of the house. If they are observed, it will be possible to control the required zone for triggering
Installation of luminaires with sensors from the outside provides for the consideration of individual points. This is the openness of the panorama, the detection angle, the permeability, the permissible load, the distance to the building envelope. Due to lack of permeability, sometimes several sensors are mounted.
