Since the appearance of the first LEDs, they have been actively used in various areas of human life. These are flashlights, household lighting, and, of course, TV screens and various gadgets that have a screen or display area. This article will focus on the SMD 5630 LED.
A bit of history
Emissions from a solid state diode were first observed in 1907 by Henry Round. He discovered that electroluminescence is observed when current is passed through metal and silicon carbide. And then the Russian scientist Losev noticed similar phenomena. He even published his discovery, however, due to the fact that the science of that time did not allow a full explanation of the phenomenon, it remained practically unnoticed. Losev was able to appreciate the practical significance of his discovery, which made it possible to create small-sized solid-state (non-vacuum) light sources with a very low supply voltage and unlimited potential for speed. He received two copyright certificates for the Light Relay. In 1961, Robert Byard and Gary Pittman of Texas Instruments discovered and patented infrared LED technology.
DevelopThe first workable diode was made by Nick Holonyak at the University of Illinois. His LED worked in the red range.
For a long time, LEDs were very expensive to manufacture. Their average price was about $ 200, which greatly influenced the scope. The Japanese managed to get a cheap LED in the early nineties. Since then, the LED has been found in almost every device on Earth.
What is the value of the LED?
LEDs are widely used in industry and everyday life for a number of useful characteristics:
- high luminous efficiency - in terms of the amount of light received from one watt, the LED is in many ways superior to standard lamps;
- high strength and good vibration and vibration tolerance;
- durability;
- large spectrum of emitted heat of light;
- low cost;
- no high voltages, which means lower input threshold for specialists and installers;
- good tolerance to low and ultra-low temperatures;
- sustainable.
This is confirmed by user reviews.
LED operation principle
The operation of any LED is based on electron-hole conductivity. In practice, this means that the element contains two different semiconductors with different degrees of conductivity. One of them is positive, the other is negative. That is, hole and electron, respectively. At the moment when an electric current is passed through the LED, at the point of contact of the twosemiconductors, the transition of electrons to free holes occurs. At the same moment, energy is released, which is expressed by the glow.
LED SMD 5630
The design of the element is a panel with dimensions of 5 mm by 3 mm by 0.8 mm. The case is made of heat-resistant plastic, inside of which there is a powerful crystal. SMD 5630 has 4 pins. However, only 2 are involved. In all specifications, it is customary to designate the anode with the number 4, and the cathode with the number 2. A special heat-conducting substrate is placed on the back side.
Parameters
Technical characteristics of SMD 5630 often depend on the specific manufacturer. But almost all of them are subject to common standards and produce elements within acceptable limits. This means that the power can be on the borders from 0.5 to 1.1 watts. The voltage range varies from 3 to 3.8 volts. The operating and pulse currents are 150 and 400 milliamps, respectively. Claimed life is typically 30,000 hours.
Comparison of SMD 5630 with an ordinary light bulb and closest analogues
With regard to conventional incandescent lamps, any LED wins to a large extent. SMD 5630 power starts at 0.5W. An ordinary light bulb, as a rule, is from 65 and above. The brightness of the element, although lower in relative terms and is only 57 lumens, can overtake a competitor if we translate all this into power per meter. SMD 5630 shows 0.34 lumens per sq. see, alight bulb - 0.031 lumens per sq. see As for the duration of the service, here the LED noticeably takes the lead. If a standard light bulb is designed to work for 1000 hours, then the SMD 5630 boasts 30,000 hours. At the same time, electricity costs are much less. This is due to the supply voltage of both elements. A light bulb needs about 200 volts, while LEDs only need about 3.
The closest competitors of SMD 5630 are 3528, 5050, 5730. It is worth noting that the marking of these LEDs corresponds to their size. For example, SMD 3528 has a size of 35 by 28 mm. A 5050 - 50 by 50 mm.
Of all the listed elements, only SMD 3528 stands out with its power so far. It starts from 0.11 watts. In terms of brightness, 5730 leads among all elements with its 60 lumens. The viewing angles of almost all LEDs are the same and are 120 degrees. The operating time also does not change much and is on average indicated by a figure of 30,000 hours. In terms of brightness, in terms of lumens per watt, of all the presented LEDs, the 5730 wins with a value of 120. The SMD 5630 has 114.
Scope of application
Because the SMD 5630 LED has exceptional performance, its application range is quite wide. It is used in tapes to provide illumination of various devices and devices. Cars, shop windows, as well as the interior of residential premises. In some cases, good intensity allows you to use the technical characteristics of SMD 5630 LEDs in street lighting.
The structure and design of the elements make it possible to mount it on a printed circuit board. When self-soldering, it is recommended not to exceed the temperature of the soldering iron by more than 200 degrees. You should also refrain from prolonged touching the element with it.
The characteristics of SMD 5630 LEDs allow it to be used almost everywhere. To illuminate large surfaces, a set of several elements or so-called rulers is used. As an example, the SMD 5630 72 LED line. It is a small panel with 72 elements placed on it. By assembling them together and mounting them in the required area, you can achieve excellent illumination of a large area of the exterior.
Standard light bulbs for indoor lighting are gradually starting to leave the market, in their place come LED, more advantageous in terms of technical characteristics. A 100 watt light bulb can easily be replaced by an LED counterpart with a power of only 11. And this is a significant savings on electricity.
The LED lamp for home lighting usually contains several LEDs. Together, they produce much more brightness than a conventional incandescent lamp.
LED strips based on SMD 5630 are also actively used as decorative elements in interior lighting. If the room is equipped with decorative niches, various eye-catching elements, then accentuating them with LED lighting will give the room elegance and a special style. LED strips contain severalLEDs that are placed with a certain step. This allows the light to scatter, which gives the room the effect of full illumination. Such tapes are mounted, as a rule, through a special adapter, which can supply the entire set of LEDs with the necessary power and stable voltage with a margin.
Conclusion
LEDs have had a big impact on almost every kind of industry. It became possible to create cost-effective lighting devices. And this, in turn, led to a decrease in the amount of pollution and emissions into the environment. The compactness and convenience of working with LEDs has attracted a large number of specialists in this field. Almost everyone can handle the connection of ready-made LED strips to the adapter, and then to the mains.
The use of LED backlighting in high-tech products also did not go unnoticed. Modern televisions began to give a richer bright picture. Smartphones have acquired an energy-efficient backlight system for their screens. Various means of indicating devices using LEDs have become much smaller and more economical.
