Philips LED lamps are considered one of the most high-quality and durable among analogues. The company itself has an excellent reputation, based on more than a century of international experience. With all the authority, on some packages of its LED lamps, the manufacturer responsibly declares that the lighting devices of this brand are able to serve reliably for more than 15 years.

At the moment, the range of Philips LED lamps is quite wide and diverse, let's look at it. There are several standard forms of Philips LED lamps, from which each consumer can choose what is right for his purpose. Technically, the lamps differ from each other by the type of cap, power, brightness, color temperature of the glow, the presence or absence of the ability to use a lamp with a dimmer. The typical Philips LED lamp energy efficiency is around 95 Lm / W ...

On the sites of modern online stores you can find a variety of Peltier thermoelectric modules. They differ from each other in temperature characteristics, electrical parameters, size, as well as the number of thermocouples installed inside the module. These modules are used both in portable refrigerators and air conditioners, as well as in amateur crafts.

It is worth noting that Peltier modules are single-layer and multi-layer, so that the installation issue is solved quite freely. In the framework of this article, we will consider several types of the most common Peltier thermoelectric modules, we will understand their device and compare the parameters. Here is a typical single-layer Peltier thermoelectric module. Two ceramic plates with a thickness of less than 1 mm are installed in the upper and lower parts of the module. They serve as a support for internal thermocouples ...

If you started a serious repair, then it is unlikely to do without drilling holes in the walls, without driving nails, without tightening the screws. But what about hidden wiring, which can accidentally fall under a drill, nail, screw? Drilling at random is life-threatening, but a preliminary search for wiring will make work safer.

In the search for hidden wiring, a hidden wiring detector will help you, just select the appropriate device in the store. Fortunately, today's stores of construction and household goods offer a wide range of compact, easy-to-use detectors of this kind, differing only in functionality, principle of operation and price tag. There are cheaper partitions, there are more expensive ones, but first things first. By the principle of operation, hidden wiring detectors are divided into: electrostatic, electromagnetic, metal-detector and combined ...

Power semiconductor devices - elements that are used in electric energy converters and in power plant circuits, are an integral component of both direct and alternating current circuits. They play the role of rectifiers or blockers that prevent switching overvoltages. Most often, these details are found in the designs of powerful turbine generators, galvanic plants, low-voltage welding devices, synchronous compensators, electric generators of cars and tractors.

Power diodes are classified into low-frequency and frequency. The first can have a pin, tablet and avalanche versions. Silicon is used to produce such elements. Modifications are used in circuits with a frequency of up to 500 Hz. They can withstand vibration and repeated shock for a short time.Power diodes are used at frequencies from 2000 Hz and more ...

What do you associate with this holiday? Probably a Christmas tree, tinsel, garlands ... right? Celebration is impossible without flickering lights. Garlands come in many forms and designs; they can consist of LEDs or incandescent bulbs. However, LED structures in our time have almost completely replaced other types of light sources. In this article we will look at what kind of LED strips are and which one to choose for the house, and which one to the street.

Most LED lights are powered by 220 volts. It consists of one or more LED circuits. Such a connection allows you to assemble a chain that can be powered from a rectified mains voltage. If there are several chains, then one of the modes of operation of the garland can be implemented. In general, they distinguish: the static glow of the entire garland. Sometimes this mode is called "fixing"? scintillation or overflow - the alternate inclusion of different chains of garland ...

Technology for enhancing comfort is now called smart. They touched almost all spheres of life. In stores you can find smart kettles, crock-pots, light bulbs and even door locks. They will be discussed in the article. Special attention is paid to this topic, because the safety of your property, and possibly personal safety, depends on the quality and reliability of the castle. Locks come in various designs, both as a standalone device and as a superstructure over a conventional mechanical lock.

Z-wave Dana Lock fits most doors. Works in conjunction with a Z-wave controller or Z-wave gateway, except for which it is compatible with Fibaro Home Center 2 and Home Center lite controllers. It is installed instead of the core of the old castle, the mechanism remains the same. There is a video on the network about the installation process of this system.In addition to the lock, a number of products are included in the Z-wave smart home system, for example, a common controller Fibaro Home Center interacts with all connected...

We use electricity every day. We don’t even notice how many times a day we press the light switch or insert the plug into a power outlet. Sockets and switches belong to wiring accessories and how long they last will depend on their quality. Buying cheap options, we do not think about whether we will save or spend more on their periodic replacement, so you need to consider options from well-known manufacturers. In this article we will talk about the popular manufacturer of sockets and switches Legrand.

Legrand company was founded in 1866, was engaged in the production of table porcelain. But with the advent of electricity and the beginning of the electrification of cities, porcelain began to be considered not only as a material for saucers and cups, but also as an insulator. Already in 1949, the company began to thoroughly engage in the production of wiring accessories. By 1966, the first international representation of Legrand in Belgium was opened. Now on the market Legrand is represented by a number of brands ...

Smart home is a system that makes technology work for you and simplifies life. In order to make your home smart, you either need to radically redo the entire wiring and introduce microprocessor or even microcomputer control systems ... Or go softer, different way, gradually equipping it with smart things. The simplest thing you can do is automate the lighting. This article will discuss how smart lamps help in this and what it is.

What is a smart lamp? The concept of "smart" or "smart" in our time is glued to almost all technology. Progress has come to seemingly such a simple and mundane thing as a light bulb.What is called a smart lamp? There are two possible answers: A lamp or a full-fledged lamp with additional functions, such as automatic switching on by popping, human presence, in the dark and by triggering other sensors. Lighting device with a set of sensors and a microcontroller system ...
