LED products today are walking at the same time in the world of electrical engineering. Economical, versatile, with high luminous efficiency and various luminous flux spectra. But there is one significant drawback that manufacturers of LED products are silent about. Read further in the article.
What is LED lamp
The LED lamp is the direct LED itself, the voltage regulation board, the bulb and the standard base. The result: beautiful light and low energy consumption. Also, you can add to everything a solid guarantee for LED products, which some manufacturers offer up to two years.
Features of electronic lamp control
In any LED lamp there is a small board, the purpose of which is to adjust the voltage so that the LED does not fail.
Any electronic board for an LED lamp consists of the following elements:
- Capacitors.
- Resistors.
- Varistors.
- Inductors.
- "Paths" are conductors of electric current.
And if varistors and inductors may not be provided in all circuits, then capacitors and resistors are mandatory elements of any of them. A resistor is a certain resistance; if it fails, it simply burns out. But the principle of operation of the capacitor is somewhat different, and this circuit element should be considered in more detail.
What do capacitors in LED lamps lead to?
A capacitor is used to reduce the pulsation of the luminous flux. It is necessary because LED lamps are "powered" by alternating voltage. When electrons flow in one direction, the capacitor charges, when moving in the opposite direction, it powers the LED. In LED lamps, and indeed in all electronics, capacitors are irreplaceable.
The main disadvantage of a capacitor is that it needs charging at the moment the voltage is applied to the lamp. When the wall switch is turned on, this small circuit element can draw a large current, sometimes reaching tens of amperes. Of course, this happens within a few milliseconds, but still such an amperage does not pass unsuccessfully for switches.
The standard wall switch is a trip unit. If you remove it, then the phase wire to turn on the light would have to be twisted and disconnected when this very light would have to be turned off. And this device is not at all designed for a passing current of several tens of amperes. Prolonged switching on and off of the LED lamp leads to a significant reduction in the life of any switch, especially the dimmer.
Interesting to know!
Many manufacturers of LED products have repeatedly indicated in the instructions for their products that you should not turn on and off the lamps too often. Especially such points could be found in the technical documentation for the first LED lamps, which at the time births became insanely popular, due to their affordable cost and low consumption electricity. Only a very few users considered it necessary to familiarize themselves with this very instruction.
