LED diodes

Diodes are common components in electronics and are used, among other things, to convert alternating current to direct current. LEDs have become incredibly popular because they are much more energy-efficient than traditional incandescent bulbs. Since the LED is a type of diode, it only lets current through in one direction. To indicate how to mount it, one leg is longer than the other. The longer leg is the anode - the leg that should be closest to the positive coil. Depending on the material used to produce LEDs, they get different colors and electrical properties. Classic red LEDs are usually operated with a voltage from 1.8 V to 2.4 V and current from 5 mA to 10 mA. At Botland.store, you will find a large selection of LEDs and accessories at reasonable prices. Check our offer, and buy the high-quality LED diode, LED stripes, and many more!

Light-emitting diodes - semiconductor light source

Light-emitting diodes are a very popular electric light source, which in many applications replaces conventional thermal, halogen and fluorescent bulbs - including compact ones, available as energy-saving bulbs. This was not always the case - when introduced to the market, LEDs emitted little light and were only used as a replacement for small incandescent and fluorescent lamps, used, for example, as controls in electronic equipment. Only recently have light-emitting diodes, capable of illuminating the surroundings, become commercially available. This coincided with the introduction of white LEDs, which use special phosphors and multicolor LED structures to emit a wide spectrum of light.

The history of the LED

The first light-emitting diodes appeared on the market in 1962 - they emitted low-intensity infrared light. Over the next six years, HP developed these solutions to create the first red LED. They were characterized by low intensity, which made them suitable only for use as indicators. It was then that seven-segment LED displays, which are still popular today, were created. In the following decades, semiconductor materials and their technology were developed , which enabled the creation of increasingly intense colors in a wider range of operating wavelengths. This also allowed the creation of white LEDs, which are made of materials emitting red, green and blue colors, thanks to which our eye registers their emission as white light. Over 40 years of development, light-emitting diodes have increased their emission efficiency (in lumens per watt) by about seven orders of magnitude. Modern LEDs are available in the visible, ultraviolet and infrared wavelength range and are characterized by very high emission efficiency.

LED diodes - Principle of operation and structure of a light-emitting diode

In LEDs, light is produced by the recombination of electrons and holes in the semiconductor . This process is called electroluminescence, hence the name of these elements. The LED is a junction device. There are natural enriched areas in the PN structure, where there is an excess of electrons (N) and holes (P). Under the influence of the applied current, electrons move from the N region and recombine with the holes existing in the P region. The free electrons are in the conduction band, and the holes are in the valence band. The difference in energy levels must be dissipated to recombine electrons and holes. This energy is emitted in the form of a photon of light. The length of the emitted electromagnetic wave depends on the energy gap - the distance between the conduction band and the valence band - of a given semiconductor.

LEDs and accessories - FAQ

1️⃣ What is the LED used for?

Compared to traditional light sources that convert electricity into heat and then into light, LEDs (Light Emitting Diodes) convert electricity directly into light. They thus ensure efficient light generation with low losses of electricity.

2️⃣ What type of LED?

At Botland, we have divided the available diodes into RGB LEDs, LED strips and matrices, laser diodes, IR infrared diodes and all LED accessories such as lampholders and drivers. Diode types differ in parameters such as wavelength, digital control, lens, illumination angle, tightness class, light color and nominal power.

3️⃣ How to connect LEDs?

Resistors are most often used before connecting to the battery. A resistor is a basic electronic component used to limit the value of electric current flowing through it. We have a full guide to connecting LEDs on the Botland Blog .

4️⃣ How to power LEDs?

The simplest way to power an LED is to use a constant DC voltage source that already powers other electronics in the circuit. You can regulate the current using an appropriate resistor - do not connect the LED directly to a battery or power supply, as it will be destroyed by excessive current flowing through it.

5️⃣ How to calculate the power of an LED?

To calculate the power consumption of an LED, simply multiply its voltage (in volts) by its current (in amps). The result, expressed in watts, is the amount of energy the LED consumes.

6️⃣ What are LEDs made of?

Diodes, generally speaking, are made of very thin layers of semiconductor material. One layer has an excess of electrons, while the other has a deficiency of electrons. Manufacturers can now produce such layers as thin as 0.5 microns or even less.
