LED usage examples
As soon as the production of LEDs reached industrially significant proportions, their widespread introduction began. The use of LEDs these days is so vast that if you look around you will almost certainly catch something that has LEDs. What explains their popularity?
It's simple: an LED is a very efficient, safe, and inexpensive light source that meets many lighting needs, not inferior to either incandescent or neon lamps, and in fact, significantly surpassing them all. Where are the LEDs used, what are their areas of application? We will try to give an answer to this question here.
First of all, we pay attention to the fact that many LCD screens, for example, screens of TVs, monitors, displays of mobile phones, and various mobile gadgets, have LED backlight. This applies to both old models and the latest, because the LEDs themselves are changing, but the essence remains unchanged.
For example, the backlight of the Retina display in an Apple MacBook Pro laptop is carried out by 48 bright LEDs located at the bottom of the display, the light of which is converted by the scattering system, so that the display displays the picture in the best way for human perception.
Single LEDs as indicators of inclusion on the front panels of various household appliances have long become the norm. Here you can recall the standby indicators of the TV or DVD-player, indicating that the device is plugged in. This also includes backlighting the liquid crystal clock on the same DVD player, and similar backlighting on other home appliances, kitchen appliances, etc.
Instrument lighting in a car deserves special attention, since it is inextricably linked to ensuring the safety of life of people, both passengers and pedestrians. The use of LEDs here also opens up great opportunities for tuning, and everything is limited only by the creative approach of the car owner.
Speaking of cars and indications, one cannot but mention the LED road signs. Over the past couple of years, they can increasingly be found both on the streets of megalopolises and on wide freeways.
As for the traffic lights, they have been using LEDs for a long time, and the appearance of powerful LEDs in recent years makes the light of traffic lights better, more comfortable for drivers.
Street LED lighting is an important step towards energy saving on a city scale. Powerful LEDs are used in street lamps, which can save energy many times, and their service life significantly exceeds any other lamps, reaching 50,000 hours.
An example of the use of LEDs in lighting is USS street lamps, which are distinguished by their versatility and laconic design. The average life of such lamps is about 20 years.
Power LEDs They are also used in industrial floodlights at enterprises, they are now replacing industrial lamps. They serve to illuminate equipment, installations, and simply as light sources in large industrial premises, large-scale workshops, etc.
Household LED lighting deserves special attention. First of all, it is important to note that compact fluorescent tubes can already be replaced by LED lamps, characterized by increased efficiency and durability. This also applies to recessed ceiling lights, and night lights, as well as decorative lighting.
Decorative lighting is a truly comprehensive application of LEDs, and especially LED strips.Luminous signs on the walls, patterns on the doors of rooms, patterns on the walls, a "starry sky" on the ceiling, light zoning of the space in the home - this is not a complete list of decorative solutions.
Emergency or night lighting, staircase lighting, furniture lighting, which makes ordinary interior items bright and unusual, souvenir lighting on shelves, and much more.As you can see, LEDs are ideal for light interior decoration.
Noteworthy is the light decoration of car interiors, which can give individuality to each salon.
External LED design of the car is another way to create an individual style.
Not without tuning and headlights. Powerful lamps can already be replaced by LEDs.
When reducing the load on the generator, the luminous flux remains quite strong, this is an important advantage of LED technology in comparison with both conventional and halogen incandescent lamps.
The existence of LEDs in basic shades (red, blue, green) creates tremendous opportunities for building large advertising displays to display full-fledged animation.
It is easy LED signs with graphics in various shades and colors, and giant canvases, like a huge screen extending 500 meters above the main street of Las Vegas, consisting of 12.5 million LEDs.
LED running lines and light boxes, in which LEDs are also used, have long become a familiar advertising attribute of stores and other establishments where owners always use modern methods of visually attracting the attention of potential visitors.
LEDs are used to transmit modulated optical radiation through optical fiber, and they also work successfully in high-speed optocouplers.
LED lamps are also used in crop production. 8 Watt LED lamps can be used in greenhouses, greenhouses, and gardens, where plants for some reason do not receive enough light.
LED lighting improves photosynthesis of plants, since LED lamps specially designed for them have a higher light output, they do not have thermal radiation, and most importantly - this is the desired light spectrum.
Special LED lamps for plants combine two wavelengths, consisting of 1 part of blue (450-460 nm) and 8 parts of red light (650-670 nm), or 6 parts of red and 3 of blue. There is no ultraviolet and infrared radiation, so such lamps are absolutely safe for any plants and for the environment.
