The LED is an electrical component that emits light when an electric current passes through it. This is a light source based on semiconductors. They are used as a standard light source in electrical equipment. In this article, you'll find a history of them, an explanation of how they work, and more.
History of LEDs
LED (Light Emitting Diode) This is an electrical element that emits and emits light when assembled or connected to an electrical current. It works according to the well-known principle of electro-luminescence and can reflect light in a clear display, as well as in infrared and / or ultraviolet light.
In particular, they have lower power consumption than conventional lamps, as well as much smaller dimensions, longer life and faster replacement than incandescent lamps, and therefore have a wide range of applications and uses in everyday life.
Currently, the LED diode is the most convenient energy-saving luminescence technology for efficient and useful use, and it is natural that it will be one of the fastest and most stable development processes over time.
LED refers to a type of light where a semiconductor converts electricity to light (without generating heat), usually in a small area (diode) of 1 square millimeter or less. So, an LED lamp actually has several light-emitting diodes.
The light created is projected in one direction, eliminating the need for diffusers and lights.
Visible LED is used as a replacement for incandescent and neon lights, as elements in versatile displays, large reflectors, traffic lights and other visual signals, as well as in computers, clocks and lights. Infrared LEDs are used in remote control units for TVs, DVD players, and other areas that require wireless control.
The advantages of LEDs are endless, but they also have disadvantages. The advantages are that they emit more light per watt than glow bulbs, they are much smaller, they have a much shorter life than other types of electric light sources (they are fast), and they have a much longer service life. stable in the long run.
In addition, it is difficult to harm them. Its disadvantages are high cost per lumen, high dependence on external temperature and easy overheating if the external temperature is too high and there is no heat sink. Despite their shortcomings, LEDs are finding their place in human use and are here to stay.
Types of LEDs
Since the new LED was introduced to the market, the technology and science have been a has created different types of LEDs with specific characteristics and uses.
Traditional inorganic LEDs
This type of LED is a traditional diode presentation that has been on the market since the XNUMXs. As the name suggests, they are made of inorganic materials. Some of them are compounds responsible for conductivity, such as arsenium, aluminum, gallium, phosphide, etc. The color of the light usually depends on the material used.
These LEDs are identified by the small LED lamps used as panel indicators, although there are many such formats. However, there are many different LED styles that can be seen and used in the inorganic LED category.
high brightness LEDs
It is a type of inorganic LED that is starting to be used for lighting applications. This type of LED is basically the same as the basic inorganic LED, but the light output is much higher. In order to produce the highest light output, these types of LEDs need to withstand much higher current levels and power consumption.
Often these LEDs are assembled in such a way that they can be mounted on a heatsink to remove excess heat. Due to its high efficiency, this type of LED is used as a replacement for several old lighting options. Home lighting with car lamps.
They have advantages over fluorescent and incandescent lamps in terms of efficiency and environmental factors. These types of LEDs have a high level of optimization and also have a long life, especially when activated frequently.
organic LEDs
Organic LEDs are a development of the basic idea of the light-emitting diode. This type of LED, as its name suggests, uses organic substances. organic type screen is produced in LED sheets and is based on organic materials that provide light diffusion.
Typically, a very thin film of organic material is pressed onto a glass substrate. A semiconductor circuit is then used to transfer electrical charges to the printed pixels, causing them to glow.
