The outdoor LED lighting with movement sensor sheds light just right and only when necessary. How to choose and what you should know before installing it?
Illuminate where to
Most often, the light projector and motion detector are both adjustable, allowing light to accurately and choose the right angle depending on the traffic areas to be illuminated.
For some lighting systems , it is also possible to select the intensity of light and the ignition timing after passage of a few seconds to several minutes.
If the projector has a setting light sensitivity , it is possible to trigger illumination only from a threshold given, eg twilight to full night. This is called twilight motion detector.
For a warm and pleasant general lighting, the color temperature is a critical parameter (for details ” choose its LED lamp “); usually a temperature below 4000 K emits a light hotter with tones of orange-yellow color (3000).
The presence detector / motion
The detector will react to movement of any type, animal or human, and this, in its coverage area or detection distance .It can be also adjustable and triggers the ignition of the lighting fixture following the detection of a movement. There is therefore need to switch and the light turns off automatically depending on the lighting time / delay previously selected.
The detector can be coupled to one or more lighting, and then plays the role of the control device for several bright spots.
To avoid nuisance tripping, it is recommended to avoid direct the detector to a source of heat or light to a reflective area or likely to experience rapid temperature changes (pool water for example, or of glazing ‘veranda)
Choose the location of the installation of the lighting:
Key element with presence detection: projector placement. It is often recommended to place it at eye level or a little higher, between 2 and 3 m from the ground.
At this height, the sensor covers a detection angle of 120 ° to 180 ° depending on the model but this may be more (up to 360 ° for some).
Over the lighting fixture is height, the higher the detection distance is great and the device is less sensitive to movements of pets.
In general, the detection distance is indicated (with a maximum of 10-15 m for projectors).
Remember also to check the degree of protection (IP – IP 44 – protected against splashing water in all directions, essential outdoor).
The types of use of the motion sensor lighting:
In most cases, lighting systems with motion detector used in traffic areas around a house (walls, porches , canopies …) but also on stairs or outdoor courtyard buildings …
They have an economic advantage incontestable :
- The light is switched on only if necessary and on a timely: These systems provide real comfort, light is delivered automatically to the one who needs …
- Equipped with lamps LED, which have a long life, the lighting projector virtually no maintenance request.
- Some work independently on solar energy. The LED lighting consumes very little, this is quite enough.
Compared to a conventional projector, the economy is more than 80% of the energy consumed. To give an order of Usprivateschoolsfinder, an LED bulb 10 W illuminates like an old lamp incandescent or halogen 80 to 100 W.
Note also that the motion sensor lighting enhance access security, both for the visitors as to deter intrusive approaches. The price varies according to the characteristics, the light power, system orientation opportunities.
