Diagram for switching on LEDs and calculating the necessary parameters
Since the LED is a semiconductor device, polarity must be observed when connected to the circuit. The LED has two terminals, one of which is the cathode (“minus”), and the other is the anode (“plus”). The LED will “light up” only when switched on directly.
Features and benefits of LED TVs
When choosing the right TV model, many consumers are faced with new terms and modern technologies. For example, not everyone knows what a TV with LED technology is and what principle its operation is based on. Despite this, today
How to determine how many volts an LED is?
Despite the fact that the No. 1 electrical parameter for an LED is the rated current, it is often necessary to know the voltage at its terminals for calculations. The term “LED voltage” refers to the potential difference across the pn junction in the open state. It's me
DIY repair of LED lamps and chandeliers
Do-it-yourself repair of LED lamps and chandeliers is not often required. Let’s say you stupidly bought this one-eyed snake at FixPrice, and then suffer with it. First, it is discovered that the LED lamp itself is relatively small compared to the gi
What functions do LED chandeliers have and is it possible to repair them yourself?
LED lighting came to Russia a long time ago. It is associated with the installation of suspended and suspended ceilings, the design of shop windows, shops, and other retail and entertainment establishments. Recently, LED chandeliers have become in demand, which
Design and principle of operation of LED TV
Recently I was asked what is the difference between LCD and LED? I answer: both of them (LCD and LED) refer to LCD (liquid crystal display televisions). Structurally, they differ from LCD TVs only in the way the LCD display (or matrix, to
Correct repair of a chandelier with a control panel with your own hands
Lamps of this type are gradually beginning to be in increasing demand. But there is no trend towards a decrease in their cost yet. Therefore, it is not surprising that Chinese products are being sold out much more actively. But the products of this production have

Features of LED TVs with Edge and Direct backlighting
LED TVs have gained particular popularity among users due to their characteristics and quality. However, not everyone understands what an LED TV is, how it differs from others and how this technology works. That's why today we decided to
Connecting LEDs from batteries
The availability and relatively low prices of ultra-bright light-emitting diodes (LEDs) allow them to be used in various amateur devices. Beginning radio amateurs who use LEDs in their designs for the first time often wonder how to connect the light
Light-emitting diode
Light Emitting Diode (LED) is a semiconductor diode capable of emitting light when voltage is applied to it in the forward direction. Essentially, it is a diode that converts electrical energy into light. Depending on the material from which
