Led lamps and their impact on human health
The devices based on diodes have appeared recently, but already managed to occupy a leading position. This is not surprising because they usher in a new era in artificial lighting.
Consider led bulb consume a much lower amount of energy compared to their counterparts. But everything is so beautiful as we are trying to get manufacturers? Not whether they are harmful to humans?
Performance of led lamps in lighting fixtures
In addition to the quality and durability of modern household appliances must possess and efficiency. In addition, they directly save money by consuming less electricity, these devices also improve the environment by reducing electricity consumption. This means that they reduce the release of toxic substances from power plants. The first electrical appliances, who became the head of this movement was the bulb. Now hardly anyone uses the classic incandescent bulbs, most opted for best option is led lamps. The reasons why they are gaining such popularity, are:
How to calculate the lamp power? Table power lights.
In the past, T. A. Edison shook the world with its discovery. He improved the design of the very first lamp using a carbon filament as the filament body. Then he suggested to pump the air out of the bulb. Thus, American scientist, was a pioneer of incandescent lamps. After a certain time the carbon filament was replaced by tungsten.
LEDs — the ideal light source
Correctly chosen lighting office, office or home is regarded as a pledge of comfort and more productivity. So today all the attention is focused on the installation of led light sources. They represent the only quality alternative to the huge number of lamps used previously.
How to choose light-emitting diode (led) lamp
What is an led
Led – это полупроводниковый элемент с электронно-дырочным переходом, генерирующий свет при прохождении электричества через него. Главным отличием светодиодного источника света от других ламп то, что в кристалле светодиода преобразование переменного тока в постоянный сопровождается minimal loss to heat.
What is LED technology, the principle of operation. The pros and cons of LED.
LED (Light-emitting diode) technology, which allows to obtain a light emission between the cathode and the semiconductor is connected to the anode (the electrons interact with the emission of photons when passing through the semiconductor to the cathode).
The led was discovered by accident when, during experiments it was found that in certain cases, the charge transfer occurs glow in the visible range.
