A street lamp with a motion sensor illuminates the area adjacent to the house when necessary. Such devices can save on the lighting of individual sections and work in automatic mode. Individual samples of luminaires are powered by built-in sources, i.e., they are essentially autonomous.
Street Lighting Requirements
The basic requirements for street lamps are regulated by the provisions of SNiP SN 541-82:
- profitability and safety of the lighting system;
- high reliability;
- ease of use.
After the advent of LED lamps in 2011, the regulatory document was adjusted taking into account the characteristics of semiconductor devices. In the future, it is this type of lighting equipment that is considered.
Types of street lights with motion sensor
Known types of street lamps with motion sensors are subdivided into wall, ground (ground) and mounted on a support in their construction. According to the principle of forming a light picture, they are divided into LED models and floodlight type products.
Wall lights can be recessed, as well as overhead or pendant. In the first case, the product is mounted directly on the outer wall of the building or under the shelter of a hinged structure. In suspended and overhead models, such protection is not provided. Ground luminaires are installed directly on the ground in the form of low columns. Lighters of the latter type are mounted on ordinary or openwork (decorative) racks.
Technical specifications and features
The street LED lamp with a motion sensor is characterized by the following technical parameters:
- radiation power;
- type of reflector;
- type of food;
- quality of electrical protection.
The power value is indicated in the passport of the street lamp and takes into account the consumption of all the elements included in it. An 8-watt LED flashlight, for example, replaces a conventional 60-watt incandescent lamp. Reflectors for these devices are smooth and embossed. The former are used in floodlight models, while the latter create scattered radiation, covering a significant area.
The characteristics of the illuminators include the type of their power supply (mains or battery), as well as an indicator of protection against moisture and dust.
Selection order
When choosing a lighting lamp, they are guided by the following indicators:
- reliability and structural strength;
- moisture resistance and dust protection;
- light level;
- ease of installation;
- radius of coverage.
Attention is drawn to the design of the product and the availability of options: shooting on the built-in camera, sound alarm. The presence of a quality certificate is also checked and the reputation of the company manufacturing the device is taken into account.
When choosing the type of lamp for street lighting, LED models are preferred.
Connection schemes for a street lamp with a motion sensor
The procedure for connecting street LED lights with a motion sensor is described in detail in the manufacturer's instructions. Users who are not confident in their abilities are better off turning to a specialist for help.To eliminate the possibility of error will help knowledge of the basics of switching light sources, consisting in taking into account the following points:
- The illuminator sensors have three or four contact terminals.
- Together with a pair of supply wires, two of them are connected to a 12 Volt source.
- The remaining ends are led to an actuator that turns the light on and off.
Conductors are marked as follows:
- plus nutrition - lived in isolation of brown or red;
- the common (zero) conductor has a blue or blue protective sheath;
- the “L” symbol with an arrow means a contact bus that controls light switching;
- “PE” - contact for grounding.
If the insulation color of the switched wires differs from the standard marking, you will have to use a measuring device and “ring” them according to the scheme given in the instructions.
Popular lamp manufacturers
Among the popular models of street lamps, Cosmos brand products stand out. These are environmentally friendly devices of small dimensions, assembled on semiconductor LEDs. Products are distinguished by their original design and relatively low cost - from 500 rubles.
Armin luminaires are available on the market with floodlights of various sizes. They can be mounted on the walls of buildings and above the ground. Equipment from this manufacturer is characterized by intense glow and mobility. The cost of products does not exceed 2-3 thousand rubles.
The Bradex models are small-sized LED illuminators in a wireless design. Electric power is obtained from built-in batteries or from semiconductor solar panels. They have an original design and cost from 400 to 2 thousand rubles.
Scope of use of fixtures
LED street lights with motion sensors are used in the following cases:
- for illumination of access areas;
- during the improvement of local territories;
- on sites in front of the garage buildings;
- to illuminate park and garden walkways, as well as the porch of a country house;
- at objects whose facades do not need constant lighting (museums, theaters and libraries).
In the first case, installing a flashlight with a sensor allows you to save on energy consumption. Since most of the time there are no people at the entrance - constant lighting in it is not required.
Good illumination of house zones is very important in terms of their improvement. However, light is needed only in the presence of people. It is necessary to turn on lighting devices at the garage sites for a short time, when its owner opens / closes and enters the room. The rest of the time, when the lamp is on, electricity is wasted.
Highlighting footpaths and the porch of the house is also needed only for a certain time, limited by the period of their use.
Outdoor LED lights are installed in the storage facilities of industrial facilities. They are also in demand on the streets of small towns and other settlements.
