outdoor lighting

Three common types of outdoor lighting for three types of outdoor lighting are mains lighting, low-voltage lighting and solar lighting.
In some industrial applicationsg.
The construction site uses the voltage between mains and 12 v.
The normal power supply is 240 V in the UK, which is usually 110 V.
The main reason is that it is less dangerous in dangerous areas while still providing quite strong lighting.
Theft of bulbs and other devices is also good as they do not work properly under normal mains power.
This provides the brightest light, almost always for safe lighting, or where bright light is needed outside.
However, since the mains cable is required to power the electric light, it must be well protected.
If the light is mounted on the wall, the cable is sticking out directly from the wall, which is fine.
If the cable is to be buried underground, armored cables must be used because the spade can easily cross the normal trunk cable. (
The Armoured cable is a three or four-core cable, well insulated and surrounded by strong steel wires.
Because the protection is stranded, it can be cut with a normal cable cutter.
Three core cable-
Life, neutrality and Earth
Used in most domestic installations, four cores are used when using a three-phase power supply. )
All lamps and lanterns must be suitable for outdoor use. e.
Water and ground unless all made of plastic or rubber.
Domestic Power-powered lamps can range from 40 watts to at least 1000 watts of floodlights.
Use the latter only if you need to illuminate a very large area like during the day.
For the sake of safety, most gardens will be fully illuminated by the lighting of up to 500 watts, and the lighting of 40 to 100 watts will illuminate a small area, such as the doorway.
Low energy bulbs can be used in many out-of-room lights, which of course is desirable if the lights are on at any time.
Professional low energy bulbs used in many street lighting, such as yellow sodium lamps, usually require specially designed lamps.
The optical tube can be used to automatically turn the lights on and off at dusk and dawn, and some lamps are built in.
Again, when someone is close, the PIR detector turns on the lights, which are usually built into the safety lights.
The photocell and PIR detectors can also be provided as separate units and can be connected to one or more lamps.
Low voltage garden lighting this type of lighting is less light than the mains supply, but it is usually still enough to light up the road, the bedding area, or, if there is enough light, and they are close enough to the desired light, even useful practical light.
The main advantage is that they all work on the power transformer, the power transformer is plugged into the power socket, but the voltage drops (usually)12V.
For example, if someone goes through the cable with a shovel, it will still cause the lights to go out, but the person will not get an electric shock.
12V is very safe, so special protection is not required for cables.
The solar garden light is the dimest outside light, but the LED light bulb keeps on.
They are usually used for effects in the garden or to illuminate the edges of the path.
They are of no use to actual lighting.
Their biggest advantage is that they don\'t need wiring.
They cut off power from the sun and just need to be trapped on the ground (
Most people have seconds to do this).
These jobs are to charge rechargeable batteries by operating solar panels during the day.
In the dark, the light tube switch on the LED bulb, which is powered by a fully charged battery.
In the summer, the light usually lasts all night, but in the winter, it may not last for more than a few hours.
The light depends on the quality and capacity of the battery.
If the emergency light fails, darkens or lasts for a short period of time, this usually means that the rechargeable battery needs to be replaced.
