LED strips are widely used in decorative lighting and functional lighting, but from time to time they fail completely or partially, in connection with which there is a need for their repair or replacement. Often, you can do just replacing a small part of it, which will reduce repair costs. In this article, we will cover typical problems with LED tape.

Before starting the discussion, I note that the main emphasis will be placed on common tapes with 12V power, 24V tapes are similar in design, and in the end we will consider the features of repairing network (220V) tapes. First, let's figure out what the LED strip consists of and why it is flexible. LED tape can be divided into two parts: a flexible printed circuit board and LEDs and current-limiting resistors. On one side, the flexible circuit board is coated with adhesive. A metallized layer is applied on the second side ...

LED strips are popular because the simplicity and ease of working with them allow you to implement many ideas. Moreover, this can be done not only quickly, but also relatively cheaply and without special knowledge. Tapes easily bend and repeat the shape of the interior or objects. They can be used as a backlight and for basic lighting. In this article we will consider what kind of LED strips are. Device

LED strip is a linear light source. Structurally, it is a flexible printed circuit board on an adhesive base. LEDs are located on it. It is cut into multiple segments along the cut line, it is applied between the pads. Depending on the number of LEDs per 1 meter, the cutting length is different. For example, for a 12V LED strip, the cutting ratio depends on the number of LEDs per meter - usually 3 pieces in a section ...

A backlit switch is a convenient and beautiful solution. It is needed in order not to look at night with your hand where the light turns on, randomly clapping on the wall. But with the transition to energy-saving, and then to LED lamps, many encountered the problem that the light is blinking or dimly lit with such a switch. The backlight also causes this effect. In this article, we will explain why the LED bulbs flash when the light is off.

The switches set the backlight of one of two possible types: a neon bulb (glow discharge indicator) or an LED. Light indication on a neon bulb, as well as on LEDs consumes low current (units of milliamps). The neon indicator lights up when the switch is in the “OFF” position, that is, when its contacts are open. When you press a key, closing its contacts, the lamp turns on and the display turns off. The logic of work is elementary ...

LED lighting fixtures and lamps are no longer a novelty for a long time, but often an ordinary person does not understand what he is buying at the store and whether a simple light bulb can somehow affect his health. The fact is that the quality of a light source is not determined by its power and how much light it gives out. These are just quantitative indicators, an indicator of the quality of light is the ripple coefficient and color rendering index.

As already mentioned, the quality of the lamps determines not their brightness, but such indicators as the ripple coefficient and color rendering index. These two characteristics determine both the perception of light and your well-being. You may have noticed that when you spend a lot of time, for example, in a garage with old fluorescent lamps, your head sometimes starts to hurt and there is a certain feeling of unnatural surroundings, and if you go out into the sun everything seems much more saturated and more pleasant for the eye ...

Fluorescent lamps (LL) are used for lighting and now, despite the fact that LED lamps make them a strong competition.Linear tubular lamps are more often installed in offices, garages, at enterprises, compact fluorescent lamps (CFLs) are installed in everyday life and in the same types of premises as listed above. For them there are characteristic malfunctions, so in this article we will consider how to fix a fluorescent lamp.

Fluorescent lamps differ in the shape of a tubular bulb, they are linear and curly. It is typical for CFL, where the flask is a tube twisted into a spiral or U-shaped. This is necessary to reduce the size while maintaining the length and area of ​​the emitted surface. In the general case, the LL flask is a glass tube into which mercury vapor and inert gases are pumped. Two spirals are installed in the flask, one at each of its ends ...

One of the most common tasks for an “apartment” electrician is to install one or more fixtures. Usually this does not create any problem, because connecting one switch is quite simple. But often you need to make sure that the bulb turns on from several places, for example, from two, more - less often. In this article, we will consider lighting control schemes with the help of several switches.

This problem is often found in private houses on a precautionary site, for example, near the front door and the gate, at the entrance to the courtyard, as well as in houses with several floors, so that it is possible to turn on the light from any floor and safely go down the stairs. The main problem is that if you install two ordinary switches on one lamp, then no matter how you connect them, they either must be on or both are off. Therefore, it will not work to control the lighting ...

A wide range of products in different price ranges is presented on the market of LED lamps and fixtures. The main difference between devices of low and medium price segments is to a greater extent not in the LEDs used, but in the power sources for them. LEDs operate from direct current, and not from the alternating current that flows in the household electrical network, and the reliability of the lamps and the mode of operation of the LEDs are more dependent on the quality of the converter.

In this article, we will look at how to protect LED lamps and extend the life of low-cost models. Everything described below is true for luminaires and lamps. The cheapest LED products use a blanking capacitor as a power source. The principle of its operation is based on the reactance of a capacitor. In simple words, the capacitor in an AC circuit is an analogue of a resistor.Hence the same disadvantages follow. ...

Lighting the workplace is an important condition for the productive implementation of tasks. The proper level of illumination is created by local light sources, which include table lamps. The comfort of its use depends on the choice of this light source. On the modern market there is a wide range of both decorative and functional lamps from simple to complex devices with a wide range of additional functions.

Table lamps can be divided into two types: decorative and for working lighting. Decorative table lamps are used to create a subdued uniform light in the room. For this, translucent diffuser shades or lampshades of glass, plastic or fabric are used. Such lamps complement design decisions in the interior and for the most part are not suitable for lighting a workplace. Table lamps create a directional beam...
