Battery-powered lamps are electrical appliances that are powered by batteries, accumulators and solar panels. Most often they use LED elements due to their low power consumption. The use of incandescent lamps is considered irrelevant due to the need for frequent replacement of batteries. This article is devoted to a brief overview of such devices.
Battery-powered LED lamps are a special kind of lighting technology. According to the advertisement, they "completely" do not consume electrical energy. Of course, here you need to make an allowance for a marketing ploy, but these devices actually consume a small amount of current. So, battery-powered LED lamps require only three AAA size batteries with a supply voltage of 1.5 V. The installation of such devices is simple and original - they are attached using double-sided tape. To make our stand-alone battery powered lamp light up, you need to press it with your finger.
Such elements are used to create decorative interiors or inas overnights. The main advantage of such devices is simplicity, reliability, durability, and most importantly, there is no need to pull cables. They are characterized by a fairly high level of brightness (they are not inferior to incandescent lamps), they do not flicker or blink like economical lamps, they do not emit ultraviolet radiation. In the event of a power outage, battery-powered LED lights continue to work and illuminate your home or yard.
These devices have an interesting design, they can be used as emergency or auxiliary lighting.
The next type of lighting fixtures that do not need a power supply are emergency lighting fixtures. In such cells, rechargeable batteries and batteries act as a power source. Such light sources are lit only when there is a power failure in the room (failures in the power grid or wiring). Emergency lamps on batteries can be both portable and stationary. As a rule, these elements can work both from the mains and from batteries. Usually they are installed in public places to indicate the direction of the exit. Installation is carried out on ceilings, walls or even on the floor. Floor standing ones are usually larger than the rest.
The third type of autonomous lamps are solar-powered elements. Often they are installed in gardens, parks, on the streets, in country lamps - wherever it is quite difficultconduct wires to connect to electricity networks. The advantage of such devices is ease of installation and long service life. Structurally, such a lamp contains an LED emitting element, a solar battery and a battery for storing accumulated electricity. They must be installed in open spaces so as not to cover the device from sunlight. Such a device lights up automatically at dusk.
In conclusion, let's say that autonomous lighting sources are simply indispensable in homes where there is no electricity, in nature, in garages and other utility rooms.
