LED - how does it work?

led lights

The operation of the LED for people who have little in common with the current can be complicated, but we will try to explain it as simple as possible. It should start with the fact that in the diode there is a connector of two semiconductors that have different charges - PN is used for such a connector. The carriers, in this case, are electrons with a negative charge and positive electron deficits, which are called holes or free places. Light is generated by jumping electrons from layer N to holes from level P. In this process, during the jump, electrons have a large surplus of energy, which is given out in the form of light. The element of the diode, which changes the electric energy into light, is a semiconductor chip that conducts the current only one way. It should also be mentioned that the intensity of lighting depends on the power of the supplied electricity.

White diode and RGB

Not everyone knows that white light does not exist in nature. So what is the result of the fact that our brain is distinguished by such a color of lighting? The consequence of receiving white light by the brain is the combination of several colors in certain proportions. Therefore, you should be aware that there is no such thing as white LEDs. The ones that we receive for white really shine in blue, but thanks to covering them with a phosphor, we perceive their light as white.
RGB diodes are also available on the market. These consist of three small LEDs in three basic colors: red, green and blue. The RGB diode, thanks to the appropriate combination of colors, can illuminate white. RGB LED lighting usually gives you the ability to control the brightness of colors, so we can create any color of light.

The advantages of LED lighting

LED lighting is becoming more and more common in our homes. No one is surprised by the LED lamp, LED sconces in the bathroom, or hall lighting using this technology. For what reason do we so willingly decide on this type of lighting?
The main and most frequently mentioned advantage of LED lighting is energy efficiency. LED lamp and other LED lamps are characterized by low power consumption, so the change of traditional LED lighting will positively affect the number of electricity bills.
The LEDs are small, thanks to which they have a very wide range of applications. They can be an element of not only central lighting in the room but also great as additional and decorative lighting.
They decide on lighting with LED diodes, we are also sure of the long lifetime of this type of lighting. Depending on the manufacturer, a specific light source can be up to 100,000 hours!
LED diodes in such light sources as an LED lamp, street lamps or sconces are a commonly used solution. Low power consumption and long life of this type of lighting allow us to conclude that LED lamps can completely dominate the lighting market, and traditional light bulbs and other light sources will go away.

HOW TO SELECT LEDs

Selecting lighting for my space should take into account the following: The quality of lighting The quality of lighting can be measured by using the CRI (Color Rendering Index). This index can take values ​​from 0 to 100, with natural outdoor light having a CRI index of 100. Substantially the natural light output in colors is the benchmark for all other light sources. In the case of fluorescent lamps, the CRI indicator is around 50-60 while in the case of LED lamps the CRI, depending on the brand of the lamp, is greater than 80. Specialty LED lights can achieve values ​​up to 98CRI. Kinds of lighting One of the most important parameters to consider when purchasing a light bulb is the type of lighting they offer. The color of the light required by a room (also called light color temperature measured in degrees Kelvin-K) depends on its use and can vary from hot to cold. Depending on the temperature of the light, the lamps can be divided into 3 categories, warm white, warm daylight...

LED strip assembly

LED tapes are more and more often used in interior design. They are most often used as additional lighting and they are used in kitchen tops, in suspended ceilings or around wall decorations, whose uniqueness we want to emphasize. In this article, we will show differences between individual LED strips, explain how to properly install them and suggest what additional elements will be necessary for their proper functioning. The correct installation of the LED strip LED tape should be glued to aluminum profiles, metal elements, flat bars or to any surface that can be used as a heat sink (heat dissipation) for the tape.  Before gluing, the surface must be degreased with a special preparation, cleaned and dried.  The tape should be soldered or using a suitable connector, connect the tape contacts with the power supply, and the power supply itself to the network through a cube or a socket plug.  Then tape the tape using double-sided tape, remembering that the glued surfa...
