Dispersers for LED strips - choice and fixing
LED lighting has appeared on the domestic market relatively recently, but thanks to its economy, flexibility and high production resources, it is gaining more and more popularity in various industrial sectors, as well as in everyday life. One of the main constructive elements that make LED-lighting comfortable, and the diode itself is protected from damage, are the diffusers for LED strips.
Functions performed by the diffuser
Although traditional incandescent bulbs are quite uneconomical in use and short-lived, the light spectrum emitted by them is the most optimal for human eyes, since in many respects it is identical to natural light. The diode strip provides bright, but cold and unpleasant for eyes lighting.
The solution to the problem was the scatterers, which are a structural part of many lamps that make the light warmer and more natural. But there are also objects that do not need to "refine" the light spectrum. An example is architectural monuments or devices that do not require protection from damage.
The tasks that the diffusers perform for LED tapes are reduced not only to obtaining low-cost lighting. Such devices are used to decorate the appearance of an object: a room, a car or an interior. You can not forget about the protective function and the vandal-proof, which is especially relevant in public places.
Modern technologies have significantly expanded the range of materials used for the manufacture of diffusers. Today, in addition to the usual classic glass, use the combined formulations.
LED diffusers can be made of the following materials:
- Polymethyl acrylate materials (acrylic / organic glass) are distinguished by high transparency, strength, resistance to aging, plasticity. It is also worth noting the flammability and fragility of the material.
- Transparent polystyrene - thermoplastic polymer is distinguished by its strength, versatility, low cost.
- Polycarbonate. Products are characterized by increased strength, durability due to UV resistance, high transparency and lightness. Adding fire retardants and fire extinguishing elements makes the material ideal for making diode lamps. At a cost, it is more expensive than acrylic.
The choice of material depends on the financial capabilities of the buyer and the requirements for lighting equipment, as well as environmental conditions.
Types of diffusers
In addition to the differences in the composition of the material, the diffusers for LED strips have differences in the way the light is applied and the surface structure, thus expanding its scope of application. The surface may differ in its color and structure.
Lamps made from prismatic glass, due to the effect of refraction of light rays, give the greatest effect of light scattering (up to 90%). With the use of frosted glass, the coefficient is not higher than 60%, while providing a cozy, muted light.
A separate type of diffusers, differing in diversity in design and color, is made using 3D-polymeric material. Such devices are mounted on lamps of large dimensions of the Armstrong type.
Profile with lens for LED strip can be installed:
- Consignment / universal.
- Mortise. Installed in particleboard or cardboard: ceilings, furniture.
- Angular. For lighting rooms, furniture.
- Interior. It is easily combined with any design of the room, used to install LED strips.
- For mounting on glass shelves with silicone gaskets.
Convenience and ease of installation allow you to do the work yourself, the main thing is to choose the necessary type of glass. Also it is worth bearing in mind that due to the fragility of acrylic delivery it is desirable to order from a trusted company, since it is dangerous to be healthy to perform the installation of a damaged profile. The diffusers based on plastic and polycarbonate are more practical, since they have a more resistant structure to mechanical shocks.
Types of fastening
Diode tape has several ways to install, therefore, and lenses are available in the form of blanks, allowing for the most rapid and convenient installation.
To install the tape, a smooth and smooth structure of the surface is required, specially designed profiles for LED lighting meet these requirements. Thus, it is possible to install LEDs in the form of rulers, strips, lamps, searchlights, rings, allowing to decorate car headlights, etc.
Flexible diffuser for LED strip is most often installed on a plastic profile to provide illumination of various interior objects in the form of a circle or along an arc on arches, car lights and circular lamps.
Diffusers for luminaires made with the use of acrylic materials are of several types: with a high level of transparency, as well as with a prismatic or matt structure. The disadvantage is fragility. Therefore, such devices are recommended to be used indoors. They are produced with a smooth or corrugated surface.
Due to the ease of processing the use of plexiglass is very popular for interior decoration of apartments, night clubs and other public buildings.
For street lighting, including transport, public places and in rooms subject to constant vibrations (underground, stations, transitions), the most optimal option will be scatterers from monolithic carbonate. Indoor use is impractical due to their relatively high cost.
Plastic diffuser for LED strip is made of polystyrene, characterized by its small price and ease of installation. It is widely used for installation on street lamps and indoors, as well as in the industrial sector. Types: mirror raster of aluminum (Armstrong lamps), opal (matte), prismatic, transparent.
The task of the diffuser is to give a soft and uniform glow, removing the punctuality inherent in the LED ribbons and lamps. Since the lighting level for different residential zones and objects is different, the fixtures must have different degrees of dispersion. In this regard, there is a separate sale of components for installation. The diffuser is selected separately depending on the customer's requirements. Convenient installation allows in an independent manner to replace a non-approached or damaged profile.
In the process of planning costs, it must be borne in mind that matte fixtures, most often used to create a warm semi-darkness in bedrooms and children's rooms, have a higher cost than transparent ones.
Outdoor diffusers for luminaires must withstand temperature extremes and shocks. Such devices should not contain cracks through which moisture can penetrate.
The new century requires new types of lighting. The usual fluorescent lamp due to its low cost still firmly holds positions in the domestic market, but the situation is changing. LEDs in combination with the diffuser, despite its high cost, are selected by an increasing number of buyers who want to not only illuminate and decorate the room, but also save energy.
