During the time of my passion for tourism, I purchased a Duracell flashlight with a powerful krypton lamp on two large D-size batteries (in the Soviet version, type 373). The light was excellent, but it drained the batteries in 3-4 hours. In addition, trouble happened twice
The demand for dimmers for LED lighting is constantly growing. This is explained by the fact that they have clear advantages over lighting devices with conventional incandescent lamps. This device is very easy to connect with your own hands. Installing it
Color temperature is one of the most important characteristics of lighting technology, which should be taken into account not only when decorating the interior, but also when selecting lamps for a car. Spectral properties, color rendering index, glow color - this is not everything
It's sad, but you need to start with theory. You will have to study the types of diodes, area and purpose of application. Without delving into the physical foundations of electronics, let's go over the search queries. It is important to understand that all diodes are united by the ability to pass current in one direction.
With the advent of “white” super-bright light-emitting diodes (LEDs), a revolution occurred in lighting technology. High energy efficiency, enormous service life, low ripple coefficient have allowed LEDs to significantly displace traditional light sources
Instructions LEDs can serve well for many years, but one quickly fails if operated at high current levels. To correctly calculate the current, you need to know the voltage for which a particular LED is designed. Supply voltage bo
The ability to change the brightness of lighting and create different lighting scenarios is becoming as necessary for a modern home as connecting to an electrical outlet or the Internet. Therefore, I recommend luminous flux regulators or dimmers for LEDs
Due to my “crazy” passion, I am often asked how to choose the right LEDs? What characteristics should you pay attention to? In order to resolve these questions, I had to sit down and write one, but detailed article, in which I would have to combine
Good afternoon dear friends! Once again, welcome everyone to the “Electrician in the House” website. Recently, the demand for LED products has been constantly increasing. The use of innovative light sources is used in various industries
With the advent of conventional incandescent lamps, the question arose: is it possible to make a device that changes the brightness of the glow. The inventors solved the problem a little later by creating a dimmer. What kind of device is this, how to choose a dimmer for LED lamps and install it yourself, p
Glow of crystals Quite often people have to buy LEDs with a power of 1 W and 3 W. If we do this in trusted stores, then there is no big problem. What if we do this at new sites? How not to be deceived? How to distinguish 1W LEDs
Since the discovery of the red LED (1962), the development of solid-state light sources has not stopped for a moment. Each decade was marked by scientific achievements and opened new horizons for scientists. In 1993, when Japanese scientists succeeded in
Testing an LED with a multimeter is the easiest and most correct way to determine its performance. A digital multimeter (tester) is a multifunctional measuring device, the capabilities of which are reflected in the switch positions on the pen.
Properly organized lighting plays an important role in everyday life. The color of the light flux created by a light bulb affects our state, perception of the environment and the shades of objects. Let's figure out what kind of light, warm or cold, will be
To check an LED and find out its parameters, you need to have a multimeter, a “Tseshka” or a universal tester in your arsenal. Let's learn how to use them. Testing individual LEDs Let's start with a simple one, how to test an LED with a multimeter. Pereve
In this article we will tell you how to choose a dimmer for LED and incandescent lamps, consider possible mistakes in choosing a dimmer, and give answers to common questions. Dimmer for LED lamps Regulators are divided into: Modular - devices,
