More recently, flashlights were the only self-contained battery-powered lighting devices used by people. Today, if desired, for your apartment or house you can buy including lamps that do not require a connection to a household electrical outlet.
The manufacture and use of sconces on batteries has become possible thanks to the advent of new modern batteries that can accumulate and hold a charge for a long time, as well as economical light sources - mainly LEDs. Such innovative devices are not too expensive. Moreover, in most cases, apartment owners can use them for a long time.
What are the devices
There are two main types of cordless sconces on batteries by modern industry:
The first type of devices is most often used directly in the house. Lamps on photocells are in most cases installed on the street. Such devices are designed specifically to make the movement of the owners of a country house in the courtyard at night more safe and convenient.
What can be a device designed for home
The main structural elements of the sconce used in residential premises are:
Batteries for such sconces are usually used the simplest. Such models can also be supplemented with motion sensors and remote controls. In addition, some luminaires of this type are able to work in different brightness modes and lighting formats.
Especially convenient owners of houses and apartments consider such sconces with motion sensors. The batteries of the models of this variety, since they turn on only when people begin to move around the room, do not sit down much longer.
Types of fixtures intended for indoor use
Such devices, in turn, can be:
suspended;
wall mounted;
desktop.
The first type of fixtures is most often used in offices, shops or, for example, in warehouses. In such rooms, battery-powered sconces can illuminate the working area, place emphasis on certain goods, etc. Such lamps are suspended either on small brackets, or even simply on Velcro.
Battery-powered wall sconces designed for wall mounting are most often purchased for apartments or residential buildings. Moreover, this type of equipment is usually considered auxiliary and is used in addition to chandeliers. Lamps of this type are suspended either with Velcro, or with self-tapping screws or dowels.
Battery-powered sconces can be used in both office and residential areas. Of course, devices of this type are also usually operated only as auxiliary devices. LEDs in them are most often used less powerful than in other varieties of battery-powered devices intended for indoor use.
What are street lights
The main structural elements of devices of this type are:
The latter in this case is, in fact, a simple chip that regulates the shutdown and connection of the lamp at night. Also, the control unit in the design of such devices is responsible for preventing complete discharge or, conversely, recharging the battery.
As the lighting equipment in such lamps, as in home, LEDs are usually used. In some cases, these can be individual bulbs, in others, whole blocks. Sometimes on sale today there are also wireless luminaires not with LED lamps, but with fluorescent ones. Such models are cheaper. However, their batteries run out faster. That is, they can be considered less convenient to use.
In most cases, batteries of this type are supplemented by Ni-MH or Ni-Cd. The voltage of such elements can vary between 1.2-3.6 V. Solar batteries of this variety, among other things, can optionally be recharged from the mains, if necessary. This feature of them will be very useful, for example, in winter, when there are few sunny days.
Types of battery-powered street lights
Such devices may vary:
according to the material used for the manufacture;
by type of battery;
by type of silicon used for photocells;
according to the installation method.
Housings of streetlights and wall lamps on batteries can be made of plastic, bronze, steel and even wood. Of course, such devices, since during operation they are often exposed to adverse environmental factors, they are usually additionally processed with various kinds of special equipment. It can be, for example, anti-corrosion paint, varnish, waxes, etc. The glass used for shades of such lamps can be smooth, corrugated or tempered.
Batteries for such luminaires can be used nickel-cadmium or more modern nickel-metal hydride. The latter type of battery is quite expensive, but has a prolonged period of service.
In addition, on the market today there are battery-powered street lights with three types of silicon:
polycrystalline - budget models with not too long cumulative effect;
multicrystalline - more expensive sconces with a long operational period;
monocrystalline - the most reliable fixtures, among other things, resistant to climate change.
How to install fixtures at home
In such devices, in most cases, a switch is provided directly on the housing. Therefore, it is best to mount battery-powered sconces intended for the apartment where it will be possible to reach them later without getting up. Actually, the installation of wireless luminaires is nothing particularly complicated.
Many of these models are equipped with reliable Velcro covers of a sufficiently large area located on both sides of the case. To install the wall sconce on batteries in this case, you need:
remove the special protective film from the Velcro;
firmly press the device to the place chosen for its installation on the wall, in the niche of the cabinet, etc.
Quite often, such lamps are mounted using conventional screws. In this case, to install:
markings are made on the wall in accordance with the holes on the device body;
holes for marking are made using a drill with a diameter slightly less than the diameter of the legs of the screws;
the device is applied to the wall;
the screws are screwed in.
Features of the installation of street lights
The installation technology of such devices is also extremely simple. In most cases, the installation of streetlights on batteries is as follows:
untwist the base of the device and apply it to the surface on which it was decided to install it;
pencil mark those places where fasteners will be screwed in the future;
drill out holes for marking;
insert dowels into the holes;
insert the batteries into the device and screw it to the wall.
The lamp thus installed at the final stage is turned on and its operation is set up properly.
Top manufacturers
Lamps and sconces without wires on batteries today are quite popular among consumers. Accordingly, many companies supply such products to the market. At the same time, the most popular brands of battery-powered streetlights for consumers today are:
At the same time, the best reviews from apartment owners deserved battery-powered home sconces:
All these models are distinguished by their attractive appearance, correct operation and a sufficiently long service life.
