Sometimes in practice we have to deal with the need for different ways of connecting incandescent lamps. Often this problem arises in everyday life, and this applies not only to lamps in the chandelier. Someone may want to improve the lighting in the kitchen, but someone will come up with a bright idea to extend the life of the lamp, replacing it with two connected in series.

Let's look at how these compounds are made, what is important to pay attention to, and what principles should be followed when performing various connections. In the figures below, simple and understandable diagrams will be given. When the lamps are connected in parallel, a full mains voltage is applied to each of them, that is, phase and zero are supplied directly to each of the lamps of the parallel circuit. And if one of the lamps burns out, the rest will shine, because their chains will remain completely intact. Parallel connection of lamps is used everywhere in everyday life ...

Do you change bulbs too often? Seriously, this question is hardly asked by those who use incandescent lamps in the old fashioned way. Indeed, incandescent lamps cost a penny, and there is no problem in replacing a burnt out bulb with a new one. If a person does not care about the energy saving problem, then everything is in order, he does not experience inconvenience.

But what about those people who have already switched to LED lamps? What if, for example, a zealous owner, deciding to take care of energy conservation, put LED bulbs at home, and they burn out all the time? In this case, you have to forget about saving, because LED lamps are quite expensive, compared with the same incandescent lamps. This is where a person is faced with a real problem. So why not eliminate the cause of regular burnout of LED lamps? Of course, it is worth eliminating it, but first you need to identify this reason. Let's see what are the reasons ...

Which lamps are better for home lighting? LED, fluorescent, halogen or incandescent? What are the advantages of some and the disadvantages of others? How economical is it to use lamps of one type or another? Let's try to figure it out.

Incandescent lamps remain the most common type of lamp in homes. To this day, they are available in various capacities, come in a variety of sizes and shapes, suitable for installation in almost any lighting device, whether it be a lamp, a night lamp or a chandelier. Incandescent lamp - the simplest electric light source. It consists of a sealed transparent evacuated flask, a metal base, and a spiral is installed inside the flask - a tungsten filament. During the operation of the lamp, an electric current flows through its tungsten filament, just causing the filament to heat up to white ...

For street lighting in settlements, energy-efficient luminaires with sealed reflectors are now used. On highways and major freeways, reflex lighting is often used with a reflective surface inside the luminaire, which allows the creation of powerful streams of directional light. For secondary roads, reflex and diffused lighting are equally suitable.

The most powerful lanterns, with power from 250 to 400 W, are installed on freeways, less powerful ones are used to illuminate secondary roads - 70 - 250 W, and scattered lighting with lamp power from 40 to 125 W is sufficient for pedestrian sidewalks and park areas.Street lighting fixtures in settlements have shades of various shapes: for parks these are balls and cylinders, for wide streets - directional floodlights ...

Creating comfort in an apartment or house is a multifaceted task, one of the essential elements of which is harmonious lighting of rooms. In the world of modern interior design, many have the desire to create a house with a magnificent design. An important component of the interior design of any room is its lighting.

Having decided to transform your living space and create a new interior in the house, it is worth paying special attention to your ceiling. The original ceiling system will not go unnoticed by guests, and you will be delighted every day. The beauty, quality and grace of a ceiling is largely dependent on its design and lighting. There are many types of ceiling designs, for example, mounted (using drywall) or suspended. There are also combined ceilings. In this article we will talk about the last - stretch ceiling and its lighting ...

Modern LED lamps can be classified according to several criteria: by the purpose of the lamp, by the type of its design, by the type of cap, and by the properties of the emitted light.

By designation, LED lamps are divided into: lamps for basic lighting in residential premises, lamps for local design lights, lamps for exterior architectural lighting and landscape design, lamps for use in explosive atmospheres, lamps for lighting streets, parking lots, bridges, sidewalks, railway stations and etc., lamps for floodlights that are installed on industrial buildings and territories.

By type, depending on other properties, LED lamps are divided into: general-purpose lamps for residential and office premises, directional lamps for spotlights, which are applicable both for local illumination of building interiors ...

The bright lights of garlands on the streets, shop windows, building facades, on trees create a unique holiday atmosphere that captivates and gives the New Year holidays fabulous magic. In addition to beauty, New Year's garlands also carry a hidden danger, as they are consumers of electrical energy and, like any other electrical appliance, must be operated in compliance with certain rules.

The correct connection of the garland to the electric network is the key to its long and, most importantly, safe operation. Very often gross errors are made when connecting a garland on the street, which can lead to negative consequences: which are limited at best to damage to the garland or various electrical components, but also the possibility of fire or electric shock ...

To adjust the brightness of the glow of the lamps, special electronic devices are used - dimmers. And if earlier this concerned only incandescent lamps, then with the advent of LED lamps on the market, there was a need to regulate them. In general, the dimmer function is to lower the average current through the lamp to the desired level, and thus reduce the intensity of the light emitted by it.

So, with incandescent lamps, triac and thyristor dimmers are traditionally used, which adjust the power supply to the lamp by cutting off part of the phase of the mains voltage. Since incandescent lamps are quite ingenious devices, then dimmers for them are quite simple in design. With LED lamps, the situation is more complicated.

Ordinary LED lamps sometimes contain in their design, in addition to LEDs, also a simple pulse converter circuit, which is designed to interact with an ordinary ...
