LED-lights on batteries are autonomous type of lighting. They are used for commercial and domestic use, can be useful for giving or in case of power failure. The luminaires are powered by easily replaceable batteries or rechargeable batteries, which allows you to provide a normal level of lighting in the shortest possible time.

The LED lamp on batteries received the widest distribution. Depending on the type and capacity of the battery, the number, brightness and other characteristics of the diodes, such lighting devices are used as emergency, outdoor lighting, for domestic, commercial, decorative use, in lighting of house territories and streets. These lights are very convenient to use, the batteries are quickly replaced, and the economical use of electricity ensures long-term use.

LED lights on batteries have significant scope of use. Thanks to independence from the general power supply network, compactness and convenience, they are irreplaceable as autonomous, emergency and auxiliary lighting.

Battery-powered LED lights are used in the following areas:

• as a decorative lighting;
• for lighting the streets, local area;
• for giving;
• as additional lighting in hard-to-reach places, for shelves and cabinets;
• for decorative lighting lawns, parks, building facades;
• for emergency lighting;
• when organizing track lighting.

All stand-alone lamps differ in power, duration of illumination, type of battery, design. This allows you to choose the right lighting in accordance with their purpose and the basic requirements for the level of illumination covered area. For example, for children's rooms, you can use decorative lamps of various shapes to create a soft, dim night light. For hard-to-reach places or furniture, bright lamps are needed, but with a limited area of ​​action.

Autonomous lighting can be used in various fields. When choosing it, one should pay attention to the lamp power, the illumination area, the duration of work on one battery charge or without changing the batteries.

The LED lamp with batteries has gained its popularity due to its numerous advantages:

• compact size;
• autonomy, work from replaceable batteries;
• durability, long battery life on one battery change or battery charge;
• the possibility of using motion sensors to turn on or touch the inclusion;
• good luminous flux characteristics.

Lamps with battery are usually installed in the following cases:

• in the absence of a power supply or emergency lighting;
• if necessary disguise the lamp housing without laying cables;
• in the absence of the possibility of using traditional lamps;
• for decorative or additional lighting.

Types of lamps on batteries

Autonomous lamps are divided into several large groups:

• hanging lamps;
• miniature nanosecondors;
• wall models;
• desktop models.

Suspended structures for home or commercial use are usually used for shops, warehouses, offices, business or residential premises. They create the necessary level of working lighting, can be applied in case of emergency power outage. Depending on the purpose, such lamps may vary in luminous flux, duration of work on a single charge, and design. Also of great importance is the color temperature - warm and neutral lamps are suitable for an apartment, for office, public and other commercial locations it is better to use neutral and cold light.

A wall-mounted wireless LED luminaire is usually used for an apartment or a country house. Such models have a small weight, they are attached to the surface with the help of brackets, and Velcro options are very popular. For the facades can be used color models of various designs, for kitchens and bathrooms - bright lamps of strict design, for children - designs with velcro in the form of stars, fairy-tale characters.

Desktop models with a battery are used most often, these are convenient lamps of compact size, used as a reading lamp, night light, additional lighting for various purposes. In the office, this option can be used for working lighting, in the bedroom - to create a harmonious, comfortable atmosphere.

Most popular models

The modern market offers various options for autonomous lamps without wires, among which the most popular are the following.

1. YG-6820. Emergency model for residential, administrative, commercial premises, can be installed on a horizontal and vertical surface using a suspension or surface mounting.
2. OSCAR-10. Special LED model with a metal housing for the downlight lighting system. Differs in an economical expense of the electric power, security from dust and splashes of water.
3. SL788-B. Very bright model with SMD diodes, providing white light. The kit includes a remote control to control the brightness level, it is possible to complete the model with motion sensors.

LED lamps on batteries differ in design, power, design and other characteristics. Such lighting devices are in demand in various areas, offer quite bright lighting and significant energy savings.

Provide coverage of a room in a country house, connect a garage or other object to the light without access to the centralized power grid? In principle, this is real with a battery. But what, where and for how much to buy a power source, we'll talk further.

The task, when the dacha is located a few hundred kilometers from the city, there is no electricity on it, and in the near future there will be no electricity, but you want light, it is not that rare. And even in the presence of a generator, it is not so easy to solve, because the unit produces not weak noise, and it consumes a lot of fuel. Usually in such cases, buy a battery. Moreover, choosing it, you need to remember that the power source must meet the following criteria:

• To be not very heavy.
• Have high capacity.
• Quickly charge.
• He worked as long as possible.
• Cost is relatively inexpensive.
• Not afraid of deep discharges.

Of the possible solutions to the problem, the following comes to mind: first of all, these are cargo batteries. But they are too heavy. There are also traction batteries. This is a better option. However, their cost is 5-6 thousand rubles. In the rest, such batteries meet absolutely all the criteria mentioned above. It is lightweight, compact, excellently withstand repeated discharges and charges. These are the so-called “full cycle” batteries. They are produced by many manufacturers, but today we offer to get acquainted with the line of traction batteries Bosch L-series. Two well-proven technologies are used for their production. These include DEEP CYCLE and DEEP CYCLE AGM, among others. Their advantages are obvious:

• Highest performance. For lighting a small room a single charge will last for several days.

• Unpretentiousness to operating conditions. Batteries of this series can operate at any temperature conditions.

• Essential capacitive characteristics. With a small mass of the battery have a capacity of 75, 100 or more amps of hours.

• Long work in the cyclic mode at full discharges. Even multiple critical discharges are not capable of disabling the battery, because it is designed with these operating modes.

• Low level of self-discharge. Leaving the battery for several months, you can immediately connect it to consumers - the light bulb will burn as bright as before it was turned off.

• Compact size enclosures. This is very convenient when considering the suburban option of using batteries.

These properties make it possible to say that the L type is excellent for solving the task of organizing lighting at those facilities where there is no centralized system of electricity supply. By the way, about the price. A battery with a capacity of 100 Ampere hours costs about 6-7 thousand rubles, which is comparable to the cost of a conventional starter power source. Therefore, the high cost of a full cycle traction battery is nothing more than a myth.

Security measures at a production plant in an emergency situation are one of the most important issues, the solution of which may be different depending on the prevailing circumstances. But when it comes to emergency lighting, they use autonomous light sources.

Under the emergency lamp means lighting that works in case of damage to the main light sources. Measures to evacuate people, the safe end of all work to prevent an emergency - all these tasks can be solved by a stand-alone LED lamp with a battery.

Emergency lighting in an enterprise, office, or other public place is an alternative to the main light source in case of a breakdown of the latter. Such a lighting device can be used in any premises. At the same time today the lighting devices used when an emergency situation occurs, subdivided into the following types:

• devices with a constant action - the light source operates continuously;
• luminaries with variable action - the light source is switched on only when necessary;
• combined emergency lights - devices with two lamps, one of which is the main one and the other one is emergency;
• autonomous lighting devices - devices operating on a battery;
• centralized emergency lighting.

LED lamp on the battery

The most practical lighting fixture for an emergency meeting is considered battery LED device. First of all, such lighting does not depend on the centralized supply of electricity, and, therefore, in the event of an accident, when the main light sources do not operate an autonomous lamp, continues to burn.

But even such a seemingly perfect device has a significant drawback - for the device to work in emergency mode it must be charged. And as you know, battery charging is possible only from the mains. From this we can conclude that in the case of a discharged battery, LED emergency lighting is absolutely useless. Therefore, to maintain such a device in working condition, a person must be appointed who is responsible for the timely charging of the battery.

Accumulator LED-based emergency light source - optimal choice  provide emergency lighting. This is primarily due to the minimum power consumption of LEDs. This is especially true when they are combined with a battery whose charge is not infinite.

In addition, the LED is designed for a fairly long number of hours of continuous operation. And if you take into account that emergency light sources are not used so often, then the LED lamp on batteries will last for a long time, the main thing is not to forget to recharge the battery in time.

Features of the choice of the suitable lamp

In the process of selecting emergency lighting is important to decide with the main parameters of the lamp.

Permanent emergency lights operate from the main power grid, in the event of a breakdown of which they will continue their autonomous operation due to the use of energy from the built-in rechargeable battery. A non-permanent device is a backup light source that is not operated in a trouble-free mode. Combined emergency lighting systems operate on a permanent basis. Several lamps are built into them, one of which will work after the main luminaire fails.

Pros and cons of LED lamps

The advantages of the LED lamp emergency lighting before similar devices include a number of parameters.

Disadvantages of the LEDs have been identified. But blindly believing manufacturers who promise a continuous operational resource of several tens of thousands of hours should not be. However, even the numbers are several times smaller than the manufacturers promised, which is quite enough for the device to operate in emergency mode.

All the nuances of the choice and installation of emergency lighting are precisely spelled out in the GOST. Here everything is very clear, we have acquired a suitable lighting device and it is possible to install, and it is impossible to predict whether an accident will happen or not. In addition, such devices according to GOST, should have certain parameters.

• Autonomous lamp must be marked according to GOST. In this case, the marking should contain information about the operating modes and characteristics of the light sources, as well as the operating time of the power source.
• The battery should be equipped with a charge level indicator. This is primarily necessary to monitor the performance of the device.
• A battery power source must have a warranty period of at least 4 years, since such a device is quite expensive.
• Electric lamp holder must also be marked. This is important in the case of replacing the lamp with an equivalent.

Based on the foregoing, it can be concluded that an autonomous light source is a rather important attribute in any production. At the same time, the LED emergency light is the simplest and most convenient to use. Although any other source of light has the right to exist. But before giving preference to one or another emergency lighting system, it is necessary to understand the whole danger of the situation.

When buying a portable rechargeable LED lamp, you need to think about its true purpose. By stopping your choice on a particular model, you either expand the possibilities of using it or narrow it down. Now consider the types of rechargeable LED lights: portable, emergency and others.

The content of the article about the types of rechargeable LED lights

The main types of rechargeable LED lamps

Rechargeable LED luminaire can be portable or stationary. Portable are low-powered, charged quickly, are used for domestic purposes, like ordinary flashlights. Emergency LED lamps mainly belong to the second type, and we will stop at this type.

Emergency LED lamp battery

Accumulator emergency luminaires are automatic lighting devices that, when the mains voltage disappears, instantaneously switch to emergency mode. One of the most popular types is the battery emergency LED lamp. It is offline without interruption covers de-energized premises within a few hours. The time period depends on the power and type of lamp installed in the lamp. Also, the glow time depends on the energy intensity of the battery. The stronger the battery and the longer the operating time of the LED emergency lamp, the greater its price.

Review of the models of portable LED lights

The most popular flashlight - battery!

And yet, all of the above models for the average person are exotic. For example, for a city dweller who goes on short walks, goes to the cottage, where he hasn’t yet had a light, or just wants to buy a lamp for frequent power outages in a house, the most common rechargeable lamp will do.

The advantages of all LED lamps are high efficiency, brightness of the beam or diffused light, long time of using LEDs (up to five years of continuous operation), focusing of the light spot and high vibration resistance.

Among the models of rechargeable flashlights there is one that will be interested in hunters. This is a professional device of small size and can be mounted near the sight. Its body is made of high-strength polymer, which means it is ultra-resistant to shocks. The handles of such lanterns are clad in thermoplastic rubber that protects from the aggressive environment of sweat and chemicals. When buying this model, make sure that it is not fake, as the device has a very accurate factory focusing of the lamp and the battery for 1000 charge cycles.

Stylized rechargeable LED lights for home

Agree that it is unpleasant to feel discrimination on any occasion! The designers involved in the development of battery-powered lighting fixtures also thought so. And what if you need a wireless luminaire in your home, but not in the traveling version, but in a housing adapted. In any, you can purchase such necessary models. After all, it also happens that there is no outlet nearby, and an extension cord is uncomfortable and ugly across the room. That's when you can take advantage of a pretty battery-powered lamp.

Appearance of such wireless desk lamps is the most diverse. They can be in the form of a floor lamp, folding with an adjustable head of light or in a modern style in the form of a beautiful crystal with a remote control, which will provide an opportunity to change the white color to whatever you like. The battery in cordless rechargeable LED luminaires is very energy-intensive and some of these devices can operate without recharging for up to 12 hours. Just before making a purchase, make sure that the choice is correct, because some models can only serve as decoration, and others as lighting fixtures.

Why is LED lighting the most popular?

If you put in one line the three most famous at the time type of lighting, you get this picture.

1. Lamps and lanterns on batteries with incandescent lamps

They can not claim to be in the first place, because they pull a lot of electricity and therefore are too heavy because of the capacious battery. The second drawback - the lamp is very tiny. It is not considered as an interior lighting device, as the design is suitable only for hiking and temporary emergency lighting.

2. Halogen and fluorescent lamps.

First of all, it can be said about their harmful for human evaporation of mercury and “heavy” light for the eyes. And the second minus - even more tiny, than the first.

At this time, they have primacy in all respects. They are lightweight, as the LED is very economical in terms of energy consumption. They have the most diverse design suitable for the interior of the apartment, for hiking. There are models for emergency lighting that are used in public places.

It often happens that there is no electricity, for various reasons, and there is no lighting. Then in the course let the candles, lanterns, well, at worst, kerosene lamps. Candles smoke and fire hazardous, the flashlight has a directional light and not always a great resource of light. I propose to make an alternative.

This design will use the available components, mainly from old computer power supplies. The schematic diagram of the device is shown below:

The power supply of the circuit is a 12V battery, with a capacity of at least one and a half ampere-hours. The role of the light source will perform the bulb "housekeeper", with a capacity of 8 - 15 watts.

Components borrowed from a computer power supply:
- pulse transformer;
- PWM controller TL494;
- high voltage capacitors (C3, C4);
- high-frequency diodes (VD1, VD2);

The remaining components must be purchased. All components are mounted on a single-sided printed circuit board, size 50mm. on 54mm. (minimum size, excluding space for fasteners).

Output transistors must be installed on the heat sink, a radiator, for example, from the processor of the old computer. Properly assembled device does not need adjustment and will work immediately. When turned on, the board consumes briefly, for a charge of capacitors, about 1.5 amperes, then, at the end of the charge, 0.75 amperes per hour.

Since the case is not there yet, respectively, the radiator for the sample is not screwed.

ATTENTION: at the output of the circuit we get a constant voltage with an amplitude of 220 volts, BE CAREFUL !!!
