Ultrabright LEDs Overview: Applications

Today LEDs are used in many areas of human activity. They are very diverse. But today we will focus on such a variety of them as super-bright LEDs.

Such products have their own specific characteristics, advantages and disadvantages, which will be discussed in our article.

Description

Super-bright types of diodes are a light source that produces super-bright light. They were developed due to the fact that not always standard LED strips can provide the required level of light.

Note! This super-bright type of product is very often used for cars.

Superbright LED strip is a superbright light source with specific parameters and performance characteristics. These products have the following operating parameters:

  • frugality;
  • high indicators of light emission;
  • durability of crystals;
  • the ability to use the product in any conditions;
  • minimum power consumption.

Note! Models with a voltage of 12 volts are very often used.

Any super-bright light source works the same way. Superbright types of diodes consist of a chip made from a semiconductor material. The chip itself is coated with doped impurities in order to create a pn junction. This structure is typical for the smd and cree models.
The principle of operation here is based on the flow of current from the p-side (anode) to the n-side (cathode). In this case, the transmission of voltage is carried out in one direction.
Such diodes have the design shown in the photo below.

Super bright diode design

The color and wavelength of the light emitted by the product is determined by the width of the working area, which transmits a signal to the materials that form the pn junction. Very often germanium and silicon are used to create this transition.
The super-bright type of LEDs (12 volts or with a different voltage) is of two types:

  • infrared;
  • ultraviolet.

For them, sapphire is often used as a substrate. But besides this gradation, there is another classification.

Product types

Today, products of this kind are divided into the following types:

  • epistar. These are high quality diodes with compact dimensions. They are characterized by a long period of work. They are widely used in the modern world;

Epistar - super-bright type diode

Cree - super bright type diode

  • cree. Such diodes operate on the basis of gallium nitride and silicon carbide. And their characteristics are distinguished by a long period of work. In addition, the cree, like other models, consumes a minimum of electricity (12 volts). Cree LEDs are most commonly used to illuminate underground and pedestrian crossings, roads and highways. Very often cree is used in hand and street lamps;

Note! This type of lighting product is characterized by excellent quality, which is why it is more expensive than other models. The 3528 and 1210 chips are slightly cheaper, but they have a lower light emission.

Smd - super bright type diode

  • smd. It is also a fairly common type of superb LED products. Smd models are widely used in a wide variety of areas of human activity. Especially often, smd diodes are used to illuminate buildings outside, as well as create high-quality interior lighting inside buildings. Smd LED strips are characterized by a dense glow, which made them so popular and in demand in the modern world.

When using this kind of products, regardless of the type, it is always necessary to use drivers to connect their 220 volt AC network. This is due to the fact that most often the products of such a plan are produced at 12 volts. A special driver (power supply) will lower the voltage from 220 to 12 volts. This must be taken into account when purchasing a product and additional equipment for it, as well as when installing lighting.

Advantages and disadvantages

In just a few years, LED light sources, including super-bright and conventional diodes, have become very popular. The reason for this lies in the following benefits obtained by installing them:

  • energy efficiency. These are the most economical light sources in terms of energy consumption. When using such products, it turns out to save up to 80%;
  • long period of service;
  • lack of heating during operation. Here it must be borne in mind that the most heated element in the circuit will be the power supply;
  • can function normally over a wide temperature range;
  • the presence of impact resistance and moisture resistance (if necessary).

As you can see, the operating parameters of such devices are very beneficial. But besides the advantages, there are also some disadvantages:

  • for external use, additional protection against moisture, dust and mechanical damage is required;
  • the need to install a special radiator;
  • sensitivity to very high temperatures;
  • the possibility of breakdown when the signal strength changes;
  • over time, the conductivity of light decreases, and the level of brightness decreases.

Today, due to the obvious advantages of such light sources, they are widely used in:

  • industry;
  • advertising sphere;
  • household sphere (LCD backlighting, internal and external lighting of objects of various types, etc.);

Home lighting

  • as a backlight on vehicles.

As you can see, despite the abundance of advantages, there are still certain disadvantages. With the right approach to installation, some of them can be leveled. The use of ultra-bright LED products will allow you to create the required level of illumination anywhere in the house or on the street.
