Agree, it’s nice to realize that the life of your LED lamp will be 5, or maybe more, years. At least that's what it says on the packaging. In fact, many sellers of LED lamps and tapes overestimate this indicator simply with the aim of attracting a buyer. After all, each of us somehow wants to take care of energy saving at home or at work, and for some it is always advisable to do this with a minimum expenditure of funds.

This is where a frugal consumer lies in wait for a tricky trap: the average LED lamp has about 7 times more light output compared to an incandescent lamp. And this benefit overlaps with any other, seemingly desirable, arguments. But in vain. In fact, there are some factors that it is advisable to pay attention to when choosing an LED lamp, and not to miss the cheapest ...

The most energy-efficient artificial lighting technology to date is LED lighting. And since LEDs are capricious, they need special power. You can’t just turn on and turn on the LEDs to the outlet, and if it looks like this, then most likely there is a converter for the mains voltage to the required low constant voltage, but it is hidden inside the base part, say, of an LED lamp.

However, we do not always deal with an LED lamp, sometimes it is necessary to connect single LEDs or an LED strip, so choosing a power supply for LEDs for someone can become quite an urgent task. Let’s figure out what’s happening in this article. A correctly selected power supply for LEDs is the key to high-quality and reliable lighting. And since the LEDs need constant current, the mains voltage must first be converted ...

No matter how economical the LEDs are, there is no limit to perfection. And the next step in optimizing efficient light sources is luminaires with motion sensors for houses and apartments. Imagine that you no longer need to press the switch button, but just enter the room and the light will turn on itself. The lamp will notice you and immediately light the light.

At the same time, we are not talking about a “smart home” system with some kind of complex software. On the contrary, the motion sensor is built directly into the lamp or is connected directly to it by a wire. Such a sensor works on the principle of an infrared sensor, the so-called "volume", which is completely safe for both humans and animals. Where can this be claimed? Firstly, in the hallways and hallways of houses and office buildings. The lamp turns on for a while while a person is walking along the corridor, then goes out, and you do not need to press anything ...

One of the stages of repairs in an apartment or a private house is the decoration of the ceiling. Before installing the ceiling, it is necessary to determine the location of the fixtures. The main task in this case is to provide the desired level of illumination in each of the rooms, while satisfying your wishes regarding their placement. In this article, we will consider the question of how to arrange lamps on the ceiling.

The options for the location of the fixtures, first of all, depend on their type. There are standard spotlights built-in type, as well as decorative, differing in material and version. A decorative lamp, like a chandelier, scatters the light evenly around the surface.Conventional built-in lamps, as a rule, scatter a directed beam of light, they can be of a non-rotary type or a rotary one, which allows you to direct ...

To calculate the illumination of various surfaces, it is sometimes very convenient to consider light sources as point sources. But in reality, there are no point sources of light, they always have some specific size and their own shape. A lamp, a chandelier, a floor lamp, a searchlight, etc. are real, that is, not point sources of light that cannot be characterized only by the power of light.

If, for example, we consider a luminous ball located in the distance, and compare it with another luminous ball, with exactly the same intensity of light, but of a different diameter, it turns out that although the balls create the same illumination at equal distances, nevertheless for the observer they they look different: a ball of a smaller diameter looks brighter than a larger ball. The reason for this phenomenon is that although the luminous intensity of the balls is the same, one of them has a larger radiating surface ...

LED strip is one of the most popular solutions for the manufacture of decorative lighting or economical main lighting systems today. It can be the light in the apartment or the backlight in the car, the luminous strip under the ceiling or near the bookshelf, finally the festive decoration of the facade of the house or the New Year's lighting of the composition on the street - you can just decorate anything with LED tapes, you just need to choose these tapes correctly for this or that application.

In this article we will talk about choosing LED strips for various purposes, note important aspects of the choice, and warn the consumer against possible errors. First, you need to decide if you need a single-color or multi-color LED strip. Monochrome ribbons shine in a specific color: red, orange, yellow, green, cyan, blue, violet or white ...

The light distribution curves of luminaires are one of their most important parameters, along with the ratio of light fluxes distributed in the lower and upper hemispheres. A lamp as a lighting device is not manufactured for one object, therefore, even at the design stage, a lamp is developed as a standard one, which can be used massively in many places.

Here, one of the key points is the distribution of the light flux in space, which determines where this lamp can be used and where it is not possible, in accordance with GOST 17677-82 “Lamps, general technical conditions”. The first thing to understand is that the light distribution curve can be symmetric or asymmetric, and there are seven main types of symmetrical (most common) light fluxes, which depends on the shape of the distribution curve ...

The range of lamps today is quite wide, and it is not at all surprising that someone may have difficulty choosing lamps. Someone still uses incandescent lamps, while someone has already switched to more economical compact fluorescent and LED lamps. Meanwhile, Federal Law No. 261 “On Energy Saving” significantly limits the possibility of using incandescent lamps in the future.

In order to help the consumer make the right choice, we compare the power of various types of lamps. Let us consider how the power of an incandescent lamp, a compact fluorescent lamp, and an LED lamp correlate with approximately equal requirements for the luminous flux emitted by them.We will compare the following three lamps: a 75 W incandescent lamp, a 15 W compact fluorescent lamp, a 9 W LED lamp ...
