The installation of a luminaire involves taking certain important precautions, particularly with regard to its connection. In front of a luminaire that you have just acquired and before making any lamp connections, carefully read the instructions for use provided, if any, even if you think you know this type of lamp thoroughly. The one you have in your hands may have specificities that you would have missed.
Light fixtures: before making connections
Take note of the installation and assembly instructions for your luminaires or PoE Lighting: Above all, do not forget to cut off the electricity before any intervention, even simple,
Your luminaire operates at low voltage and therefore cannot be connected directly to the mains: do you need a transformer or is it supplied with the lamp?
Use tools that meet safety standards, they must have an insulating coating on the handle of the screwdrivers and arm of the pliers),
If you have to embed spotlights in a false ceiling, be aware that special precautions must be taken to guarantee safety, in particular respecting the distance from flammable material and from the ceiling (10 cm).
The advantages of an automatic system
The motion detector multiplies the advantages:
- It enables substantial energy savings since the lamps are activated only when needed and there is no longer any risk of leaving a bulb on inadvertently;
- It is more comfortable than a classic switch , because you don’t have to look for the ignition button (useful when your arms are full of shopping or you are carrying a child);
- It is more reassuring , since the ignition is triggered as soon as a movement is detected, which makes it a first deterrent system against intruders (alarm systems are often connected to motion detectors).
Why install sensor lighting?
Indoors, this type of luminaire is justified in all passage rooms requiring brief light : a corridor, stairs, a cellar, a garage, an entrance hall, a technical area, a car park. They are also often found in the common areas of buildings , the typical place where the need for lighting is very punctual!
Outside, it can be installed in the access driveway to the accommodation, to illuminate an outside staircase, the front door . But it is also useful for the garden or a terrace , when night falls.
Motion detection devices must be waterproof and dustproof , with a minimum protection index of IP44 or 55. For outdoor use, they must include a twilight sensor to avoid switching on in broad daylight.
How does presence detection lighting work?
The motion sensor is actually, electrically speaking, a switch. Unlike a conventional device, this one is automatic: it turns on the light as soon as a movement is registered by the sensor . It can be a human being, an animal… or even an insect, because the device detects the thermal radiation emitted by the body of living beings.
Once activated, the light only turns off after a period of time determined by the switch’s timer. This duration can be configured. If you go back in front of the detector, the time delay restarts at zero.
Some motion detectors combine a “sensor” which also measures the ambient light . In this way, the light will only turn on if it is dark. This is particularly interesting for a projector installed outdoors or in a glazed hall, for example.
Choose your light fixture and bulbs
There are a number of lights with presence detection. To choose yours, consider a few criteria :
- The response time between detection and ignition;
- The range of the detector (between 3 and 12 m in general);
- The detection angle (from 80° to 360°);
The most suitable bulbs for this type of projectors are LED Lighting , because they light up immediately (no warm-up time). They are also very economical and have a long lifespan, while guaranteeing optimal power, especially on long-range luminaires. Solar motion-sensing and “all-inclusive” lights
More and more models include the luminaire and the sensor in the same device . This way, you no longer need to redo your installation, just plug the projector into your electrical supply. Similarly, some LED bulbs have a presence detector integrated into the globe : they can be installed in any light fixture!
Finally, for the exterior, lamps operating with the sun have appeared. Autonomous, the solar lamp with detector makes it possible to illuminate the garden or an alley without electrical installation. It only turns on if it registers movement and the ambient light is low.
Solar lamp: how does it work?
Solar lamps are very useful for enjoying 100% autonomous lighting. Once installed, this type of lighting operates completely independently without even being connected to a power outlet. But how can the light turn on at night, when the Sun that powers the solar panel has disappeared? We will explain to you how this well thought-out system works.🌞
solar lamp working
What is a solar lamp made of?
In a solar lamp , we always find the following components: a solar panel, a battery, a programmable card and LEDs. Some solar lights also have a motion detector.
solar lamp components
Now that you know the list of components, it will be easier for you to understand how solar lights work. Everything is actually played on the battery, which stores the electrical energy created by the photovoltaic panel during the day.
How does the lamp light up at night?
As you know, a solar panel creates electricity. During the day, this panel distributes the energy to a battery placed in the lamp. The battery keeps it until nightfall, when it will power the LEDs !
how does a solar lamp work
To sum up, the secret of the solar panel is the presence of a battery. Often lithium, it accumulates enough electricity during the day to be able to power the light all the following night! But… how does the lamp know that it’s dark?
How does a solar light know it’s dark?
When the electronic card of the lamp detects that the solar panel no longer produces electricity , it concludes that it is night. This is why solar lighting turns on by itself in the absence of the Sun!
We hope that our explanations as well as our diagrams have helped you to understand how solar products work.
