LED street lighting

LED emits monochromatic light (contains only one wavelength). Then most important information is the so-called color temperature which is expressed in degrees Kelvin [K]. The sun’s surface temperature is 5780 K, and the peak of its radiation’s wavelength is at 500 nm.
Even though the degrees are big in the light devices, it does not mean that the lamp will heat up to this temperature, but that the light emitted by it corresponds to the maximum emission value of this temperature. Attached please find some indicative color temperatures.

Warm white: > 2700 K
Intermediate white:2900 - 3000 K
Cold white :4000 K
Daylight:5000K

Due to monochromatic radiation, a 5000 Kelvin light has proved to be the most popular in use. LED’s typical rated current is 20 milliampers [mA], and the threshold voltage, i.e. the voltage crossed for the LED to start conducting is 1,5 – 5 Volts [V]. The threshold voltage depends on the color of the LED, i.e. the semiconductor materials used in it.
The power should be thus restricted for example with a resistor, so that it does not exceed the allowed value. If a 12 volt voltage is in use and the LEDs threshold voltage is 2,9 volts (voltage when the current begins to circulate) and 20 mA current, the needed series resistor to restrict the current is 470 Ohmns [%uF057].
We must notice that in this case, considerably more power is used in the resistor (172 milliwatts, mW) than in the LED itself (57mW). It is worth it then to use methods in which the conduction voltage in the LED is smaller, and the restricting resistor also consumes less power or is not needed at all, when the whole power in use is focused on LEDs. This can be achieved, for example, with a series connection. In this case, four LEDs in a series would exactly make the used 12 volts.
Since the light efficiency of one traditional LED is really not enough for lighting, power leds have been developed, and their light efficiency (and electric efficiency used) is much greater than that of the traditional LED’s, all the way until one watt. Their light efficiency has also improved, and is even 80 lm/W. However, power leds form much waste heat, and it has to be cooled down. The LEDs’ efficiency starts to fall strongly if they heat up too much. The alternative is to use traditional LEDs connected to a series.
Then also the light pattern can be targeted to a wider area, and the light fitting itself looks beautiful, as the many small light spots form a light source.
The latest LED technology studies done in Meijo University in Japan, have led to the development of even 130 lm/W LEDs. A normal incandescent lamp produces only 15-20 lm/W and 60-110 lm/W. It is clear that in the future the lighting technology will increasingly utilize LEDs. In the future, the LED light fittings’ prices can also be competitive with the current light fittings as mass production and technology develop.
LED lighting has many advantages compared to the traditional incandescent lamp. The biggest is the possibility to save energy when energy becomes scarce, and the climate change caused by energy production causes concern. On the other hand, as LED lights do not heat up, much, they are easy to install in places where the heat is harmful or can cause, for example, a fire danger.
By adding a sufficient amount of luminous LED lamps, we can achieve sufficiently bright lighting in any area requiring resolution. In addition, LED lights are much more durable than any other lighting technology. The lamps can last even 100,000 hours, meaning 10 years of continuous lighting. Traditional lamps only reach a fraction of that time. Although as they get older, the light efficiency of LEDs starts to fade, and they cannot withstand heat. In the lighting of a sauna, the age may be much shorter than, for example, in outdoor use.

LED street light

The light-emitting diode is based on semiconductor technology. Components used in electronics, such as diodes and transistors, are called semiconductors. Semiconductors are, however, like their name indicates, materials which conduct electricity in a weaker manner than the real conductors, such as copper.
This is caused by the fact that in the material’s atom’s outer shell composed of electrons there are four electrons in the so-called conduction band, when conduction is present it has two electrons and when it is insulating has eight. The conduction band of the insulators is thus “full,” and the electrons cannot move from one atom to another, whereas the charging materials have space for the electrons to move. The function of the semiconductors is thus somewhere between these. In electronics, the most important semiconductors are silicon and germanium
In the nucleus of the silicon atom there are 14 positively charged protons, and in its electrical field there are 14 negatively charged electrons with three shells. In the inner shell 2 electrons can be found, in the middle shell 8 and in the outer shell 4. These types of atoms can bind to one another so that they join each other in the outer shell to form a covalent bond. When the outer electron belt has four electrons, the atom can bind with four other adjacent atoms thus forming a steady crystal structure.
When small amounts of other materials, which contain more (or less) electrons in the outer shell, are added to the semiconductor, a disturbance in the covalent bond is made. This kind of disturbance causes either the gain or loss or an electron in the outermost electron shell. If the added material, for example arsenic, causes the addition of an electron (so-called donor atoms) the structure will have one electron that does not participate in the crystal structure.
Since the electron is negatively charged, this type of semiconductor is called type N. Similarly, if the semiconductor is mixed with a material, for example boron, which causes the leaking of electrons (acceptor atom), a positive charge will be generated, because one negative electron has been taken away. Then the electron that left only leaves an empty space, a hole, which acts as a positively charge carrier. This type of semiconductor is called type P.
We also talk about majority charge carriers (type N) and minority charge carriers (type P). By combining the two different types of semiconductors, we get a PN junction, which is composed of type P and type N semiconductors and the interface between them. This union forms a diode.
The density of charge carriers (holes and electrons) is the greatest in the vicinity of the diode’s interface. From the interface, electrons from the N side move to the P side, and the electrons fill available holes, which then disappear. This phenomenon is called recombination. Correspondingly, from the P side holes move to the N side and are filled with extra electrons, they recombine with the electrons.
When the charge carriers thus move across the interface, they leave behind them in the charge layer’s P side a positive charge composed of acceptor ions and in the N side of donor ions
The layer begins to resist the diffusing currents, and the diffusing currents stop. In the interface zone is thus created an area, which has donor and acceptor ions, but almost no free charge carriers.
The PN union is in balance until external energy is brought to it. If the external voltage source’s positive pole is connected to the PN union’s type N material and the negative pole to the type P material, the PN union is connected to the reverse bias. The reverse bias voltage causes the widening of the interface zone and the growth of the barrier. A slight leakage current, less than a microamper, travels to the reverse bias. This current depends on the temperature.
If an external source of voltage is connected so that the negative pole is connected to the type N material and the positive correspondingly to the type P material, the interface zone narrows and the majority charge carriers cross over the interface, and the current begins to circulate. As the voltage increases, the current’s rate rises noticeably. Nevertheless the current’s rate cannot grow unlimitedly, but it has to be regulated, for example with a resistor connected in serial. In light diodes, the current is conducted clockwise over the diode, and the recombination of the electron hole pair causes the emission of a photon (emission = the sending of particles or radiation). This causes the light effect.
Already as early as the beginning of the1920s, Henry Round noticed that the semiconductor union could generate light. In the middle of the same decade, the Russian Oleg Losev developed the first LED but went unnoticed. In 1955, Rubin Braunstein of RCA noted that the gallium-arsenide mix radiates infrared light, and in 1961 Bob Biard and Gary Pittman received the patent for IR-LED.
In 1962, Nick Holonyak developed the first LED functioning in a visible area. In 1972, George Craford invented the yellow LED and ten times as bright as the previous one red and orange LED. Professor Shuji Nakamura developed the bright blue LED based on indium gallium nitride and shortly after that by using theY3Al5O12:Ce phosphorus coating to mix yellow light with blue light he achieved the white LED. Professor Nakamura was awarded the world's biggest technology award, the Finnish Millennium Technology Prize, for his invention. The picture below shows a white light-emitting LED.

LED street light (Light Emitting Diode)

LED street light is vital for all creatures on earth, only the rare forms of life found in the ocean depths do not rely on light to survive. An important source of light is of course the sun, but during the night and in other dark conditions we have to rely on artificial lighting.
Historically, light has been produced the longest by different techniques based on burning. After the invention of electricity, the production methods for light have increased considerably and the efficiencies of light production have grown.
The incandescent lamp invented by Edison in 1879 is still the most common light production method in use. The light based on an incandescent filament was introduced much earlier in 1802 by Humphry Davy, who is better known for the arc lamp he introduced in 1810. Before Edison many others developed (22 people in total according to historians) and even patented the incandescent lamp, but Edison got it into a commercial shape due to his inventions of electricity production and distribution methods. For a long time, incandescent filaments made from coal was used in incandescent lamps, and the shift to the current tungsten filament took place in 1910.
It is thought that light emits particles known as photons or light quantum, which have no mass or charge. The modern quantum theory of light was introduced by Albert Einstein. In a vacuum, photons move at a speed of 300,000 kilometers per second. The word photon comes from the Greek φως meaning light.
The incandescent lamp’s operation is based on conducting electricity over the incandescent filaments acting as a resistor. The tungsten filament is inside an air-proof bulb in shielding gas, typically argon. Now when the electric current is conducted through the filament, the filament heats up powerfully to 2000 – 3300 Kelvin [K]. (On the Kelvin scale, the zero point is an absolute zero point –273,15 ºC.)
The heated filament radiates on a wide spectrum, of which only a small part is in the area of visible light. Most of this radiation is heat radiation and thus does not provide light, though the heat generated in houses with electric heating decreases the need for heating almost correspondingly. The incandescent lamps’ light efficiency is very small, only around 5%. The visible light’s amount unit is the SI standard’s unit lumen [lm].
The efficiency is thus calculated by dividing the amount of lumens produced by the power [W] used. The problem with incandescent lamps is also their relatively short life. Since the resistance of the incandescent light when cold is much smaller than when warm, the break usually happens when turning on the light, as the momentary big charge burns the incandescent lamp and cuts it.
The disadvantages of incandescent lamps have led to the development of new lighting techniques, among them the so-called energy saving light bulbs. These are partly problematic regarding the environment because of the mercury they contain. LED lighting has been developed as the newest lighting idea, which despite all the suspicions seems to become a very notable lighting method leading to energy savings.
