The use of LEDs in lighting technology is expanding every day. While they have not yet become a complete replacement for all light sources such as HID lamps, they appear to have good prospects.
LEDs have now become affordable, they consume significantly less energy than incandescent and halogen lamps and provide quite a decent quality of light. All this makes them very popular in the consumer segment. In lamps, LED can be presented either as a familiar lamp with a base and a familiar shape, or as an integral part of the lighting device (this is the so-called LED module located on the board), and usually, it cannot be replaced, only together with the lamp itself.
If two or three decades ago light-emitting diode (LED) was used exclusively as an indicator in devices, now it is actively replacing traditional light sources.
LED modules are used to equip lamps of various shapes and purposes. In everyday life, these are LED strips and linear lamps based on them; flat lamps for decorative or local lighting, furniture lamps, and spotlights.
10 advantages of LED lighting systems
- Properly designed LED lighting fixtures provide high uniformity of illumination.
- These are digital devices whose parameters can be precisely adjusted using control systems.
- The ability to create directional light sources that have higher efficiency compared to lighting devices that emit light in all directions.
- The energy efficiency of LEDs can be up to 5 times higher than incandescent and halogen lamps.
- The useful life of LEDs is several times higher than that of traditional light sources.
- LEDs do not produce IR radiation and can be installed where IR heating is not desired.
- Unlike fluorescent lamps, LEDs do not emit harmful ultraviolet rays that destroy some materials and discolor paint.
- LED light sources can operate in low temperatures and vibration.
- RGB lights can produce millions of colors and have different color temperatures without the use of filters.
- LED lighting devices are inertia-free: no time is required to warm up or turn off.
Lamps of all types of base
LED lamps are now available with almost all types of bases that are used in everyday life. These are models with a screw base E27 and E14 and with a pin base (GU10, G4, GX53, etc.). The compact dimensions of the LED module allow it to be used as a replacement for furniture lamps, which previously used halogen lamps. LED models have lower energy consumption, but their main advantage in this case is a longer service life. Therefore, it makes sense to install LED lamps primarily in hard-to-reach places where replacing lamps is difficult (in the same furniture, for example). At the same time, do not forget that overheating is harmful to LEDs – the lamps must be provided with heat dissipation.
Structurally, LED lamps are a “cluster” of LEDs together with a built-in driver (current stabilizer), from which the LEDs are powered. The LEDs are enclosed in a transparent or frosted bulb, and in the latter case, such a lamp is visually indistinguishable from other types of lamps. Perhaps only the metal heat exchanger-radiator indicates that this is an LED lamp.
LEDs are a convenient light source that can provide general and accent lighting, be used to create direct and indirect light, provide functional task light, as well as relaxing, mood-setting, cool and stimulating, warm and cozy, colorful and playful. It is no coincidence that industrial designers are very fond of LEDs. It has become much easier to create new lamps and think through unusual shapes. Previously, it was necessary to think about how and where to place the lamp in the product, take into account its physical dimensions and the strong heating of the material. Now designers can create continuous curved shapes, evenly glowing flat surfaces over large areas. Light lines from metal profiles with LED strips can move from ceiling surfaces to walls or floors, outlining the interior with a light graphic pattern. Lamps that have become style icons and have existed for several decades now appear in updated versions – LED. The most important thing to remember is that light shapes space. He can create and destroy, deceive and guide, decorate or spoil. Light is a powerful tool both indoors and outdoors.
Glowing tape
Besides lamps, a very common way to use LEDs is LED strips. LED modules are placed on a flexible basis in one, two or three rows. The more modules, the brighter the lighting will be. The tape is in most cases presented on reels of 5 or 10 m, it can be cut in certain places (usually after 10 cm, and this is indicated by the corresponding symbols on the product).
Most often, an LED strip is used as an eaves ceiling light, gluing it onto a thin metal profile or directly onto the surface itself. This application is primarily decorative; it is usually not possible to obtain enough light. But the effect will be interesting. You can make a “floating” ceiling, podium, shelves, etc. In another case, tape glued to the bottom surface of the cabinets above the kitchen worktop will provide uniform bright lighting when cooking. Waterproof models with a silicone shell can also be used in the bathroom.
There are LED strips that reproduce both regular “white” light and color RGB strips. The latter are used to create vibrant and dynamic light displays. For this purpose, complex systems are used, consisting of a large number of LED lamps of variable color. They also contain power supplies and controllers that control, synchronize, and switch lighting devices to create various lighting effects and dynamic color-changing light shows.
About the variety of profile lamps
So-called linear lamps are created on the basis of LED strips. They are a profile with an LED strip connected inside. Such lamps are universal: they can be used both in technical rooms and for lighting public and residential interiors. The body of some profile models has a compartment for the power supply, which significantly improves the appearance of the finished luminaire. Installation of lamps is carried out using special fasteners for surface-mounted or suspended installation.
Linear luminaires can be used for both main and local lighting. The advantage of such devices is their relatively small depth, limited by the thickness of the profile, which makes it possible to create almost flat structures.
As local lighting, such lighting is most often used in the kitchen in the work area. For this purpose, linear lamps are used, which are mounted on the lower surface of the cabinet. However, the need for such lighting may arise in a workshop, or in the workplace of a schoolchild or student.
To create uniform lighting, lamps with wide diffuse screens are used. For decorative lighting – lamps with directional beams of light.
The aluminum profile is complemented by a large number of components: connectors, plugs, and fasteners. This allows you to create interesting design models of lamps: overhead or pendant, straight or cubic, strict lines or original.
Such models have a number of advantages over conventional ready-made lamps:
- Exclusive luminaire design at lower costs.
- The ability to change the lighting by simply replacing the tape (light color), adding a controller, and making dynamic lighting.
- Easy to replace the strip, like a light bulb in a regular lamp.
- A reliable tape will ensure a long service life of the lamp.
The production of exclusive designer lamps is an interesting task in which creativity is practically not limited by technical boundaries. For example, there is a special flexible Arlight ARH-BENT profile for creating lamps in the form of waves, circles or spheres. The desired shape of the profile can be given directly by hand, but to obtain perfect bends, we recommend using rigid frames or blanks. Simply wrap the profile around the frame with slight tension and then carefully remove it. The diameter of the circle must be at least 20 cm. The KLUS PDS45-KUB profile is interesting for others: it is used to create volumetric cubic structures, for example, original designer lamps: pendant, wall or floor. However, even with the help of universal profile models, you can create truly unique designs. For example, KLUS PDS-S and KLUS PLS-GIP profiles are most often used for making light lines, but good imagination and skillful execution allow them to be used to create original designer chandeliers.
