Lamps with batteries: overview

Lamps on batteries are electrical appliances powered by batteries, batteries and solar panels. Most often they use LED elements due to their insignificant consumption of electricity. The use of incandescent lamps is considered irrelevant because of the frequent replacement of batteries. This article is devoted to a brief review of such devices.

LED lamps on batteries are a special kind of lighting equipment. According to the advertisement, they "do not" consume electric energy. Of course, you need to make an amendment to the marketing move, but these devices and in fact have a small current consumption. So, LED lamps on batteries need only three AAA size power elements with a supply voltage of 1.5 V. Installation of such devices is simple and original - they are attached using double-sided tape. To our self-contained lamp on the batteries lit up, you need to press it with your finger.

Such elements are used to create decorative interiors or as nightlights. The main advantage of such devices is simplicity, reliability, durability, and most importantly, there is no need for cabling. They are characterized by a fairly high level of brightness (not inferior to incandescent lamps), do not flicker and do not blink like economical lamps, they do not radiate ultraviolet. In the event of a power outage, the diode lamps on batteries continue to work and illuminate your home or yard.

Such devices are interesting design, they can be used as emergency or auxiliary lighting.

The next type of lighting devices that do not require power supply are emergency lighting. In such elements, batteries and batteries are used as a power source. These light sources are lighted only when the power supply is interrupted in the room (malfunctions in electrical networks or wiring). Emergency lights on batteries can be portable or stationary. As a rule, these elements can work both from the network and from the batteries. Usually they are installed in public places to indicate the direction of exit. Installation is carried out on ceilings, walls or even on the floor. The floor is usually larger than the others.

The third type of stand-alone lamps are solar cells. Often they are installed in gardens, parks, on the streets, in country lanterns - wherever it is difficult to conduct wires to connect to electricity networks. The advantage of such devices is the ease of installation and long service life. Structurally, this luminaire 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 block the device from sunlight. Ignite this device automatically at dusk.

In conclusion, independent lighting sources are simply indispensable in homes where there is no electricity, in nature, in garages and other outbuildings.
