LED FLEXIBLE NEON LIGHT
In general, flexible neon has phenomenal properties: it is shockproof, resistant to moisture, and therefore it is perfectly suitable for indoor and outdoor use in lighting and decorative illumination of architecture, decorations, lighting of arches, buildings, complex architectural forms, shop windows, bridges, buildings , shop windows, theater posters, pointers.
In the industrial field, neon is made in two versions:
• cold glow
• warm glow
To select a glow, you need to determine the scope.
Cold glow is suitable for decorating the facade of buildings. Warm glow is more suitable for interior design. Two types of neon are also distinguished. One of them is LED. This type of flexible neon is more relevant in the advertising field. It consists of LEDs that fit into a PVC cord.
The LED cable does not heat up and it bends easily meaning you can create any shape. Such a sign will work at temperatures from -45 to +50°. It is used to illuminate buildings and interior designs, to decorate advertising structures, and in lighting for holidays and celebrations. Neon lights turn the room into a comfortable and cozy place. If you select the right colors and shapes, any room can become intriguing. It all depends on the design concept of the room and desires.
Types of neon signs:
Neon letters and signs in shop windows can be made of a transparent or opaque material (most often it is plexiglass, polystyrene or PVC) on a metal frame or fastened directly to the surface. Installation is made on thin cables, fishing line or directly on the wall. The main advantages of such advertising are a quick production time (2-4 days), a bright and attractive glow that works both in the daytime and at night, the long service life of the sign, affordable cost and low power consumption
Neon lettering for home
This is an excellent choice in the quality of decoration of walls, residential areas, corridors. They are an architectural addition, introducing a peculiar style of light that emphasizes individuality and design features. They fit seamlessly into interiors, creating special lighting zones. Small overall dimensions are often used to reduce the number of components that can be removed both in special niches and for the sign itself.
Neon for presentations, exhibitions and events
Emphasize any composition with bright neon lights. They give individuality and attractiveness, and create a special and unique style. Usually these are separate inscriptions, but often whole compositions can be placed on an entire wall.
Neon signs for photo shoots and for weddings
Decorate spaces and create bright light photos with neon colors. For weddings, a combination with natural or artificial flowers is used, as well as in the design of festive halls and street events. The ability to choose the right exposure and shooting mode allows you to create unique artistic photos with neon.
Neon signs for a bar, cafe, restaurant
There is also an application for decorative design, designation of zones, additional illumination, and they are a great addition to interior decoration by creating a soft, pleasant neon light. For many years now, it has been the best interior lighting design available. The main advantages are a stylish appearance, a calm pleasant light, making it one of the best options in the design of bars and cafes.
Other uses of neon include;
• Lighting the facade of the building along the contour
• Lighting of advertising structures on the contour
• Decoration of gardens and parks
• Decorative lighting of the ceiling, floor
The LED screen is a large multimedia complex that is designed for around-the-clock continuous work in the open air. This screen is designed with durability in mind, and manufactured to withstand exposure of harsh environments, such as: high humidity, dust, snow, rain, high and low temperatures. Used for a variety of purposes: entertainment, broadcasting news.Application area
The scope of application for Outdoor LED Video Screens is quite broad. They are most in demand for outdoor advertising. They are designed to be seen every day. Often, they can be seen under elevated parts of highways and in shopping centers. The LED screen attracts a lot of attention, which is why it is so actively used in advertising. If compared with classic billboards, the advertising screen has an advantage by having the ability to display a dynamic picture with bright text which colorfully describes services or products of your choice, therefore allowing your advertisement to be more informative in detail.
Another area of application is to show business. Each concert venue today has the opportunity to broadcast events which are performed on stage. The LED screen on a stage gives you the option to decorate the show, by showing off LED effects and dynamic video sequences. Venues could also use LED screens to market certain brands and products which are offered in-house, as well as display any sponsors or business partners of the event.
Nowadays, all large shopping centers are decorated with LED screens. The stores that display LED screens become more noticeable to the public are able to advertise their brands, services and current deals. This creates convenience and helps the potential customer notice your product or service.
Design features, specifications.
Every LED screen has a modular structure – thanks to the modules, it is possible to assemble structures of any size and easily assemble them at locations on a high level.
The image should always be clear and bright.
Consider the general principle of designing any modern LED screen:
The image is formed by connecting luminous points which are arranged on narrow raster grids of rectangular shape;
Dots or pixels consist of several LEDs, usually in three primary colors — blue, green, red;
Pulses are applied to the LEDs, resulting in flows of different colors and degrees of intensity. These streams are formed in one pixel and can make a palette of billions of colors: the brightness and color of each individual pixel are controlled – an image with the desired color is obtained on the screen;
The reaction speed of LEDs according to the control pulse is very high, allowing the possibility of streaming animation, pictures and videos on the external LED screens.
LED grids for streets usually have colour, while the connections between the blocks and power circuits have protective properties from weather. Often, suppliers are provided with modules for LED screens with a control system. Specialists will then assemble an external installation at a permanent location.
When ordering a LED screen, you need to pay attention to technical specifications which will contribute to a long service life:
The brightness is determined by the types of LEDs and the amount of current that passes through. For outdoor screens with a specific brightness in which the black and white balance is observed, the figure is 5500 cd / sq.m.
The contrast is usually higher if the distance between each LED in the matrix is filled with a dark compound (thermoplastic polymer resin).
The construction of the radiation pattern in the LED screen depends on each LED. In order for the pattern to fully comply with the directivity pattern of a separate diode, it is necessary to use LEDs of different colors and color schemes with the same design parameters. The LEDs need to be mounted in the screen with the lowest possible deviations in the angles of inclination relative to the axis line and height. If the LEDs are oval, it is important to note that turns are not allowed relative to the axis.
An important characteristic is resolution. It is expressed in the density of the location of pixels vertically and horizontally on the screen. it is this characteristic that the information content, elaboration of every detail of the image, and the smoothness of the lines depend on. It is not needed to strive for maximum resolution as the total price of the screen will be very high, one’s eyes will quickly get tired of one look, and small details will still not be visible from a far distance, but only the large details. In this case, the permissible pixel pitch is determined, at which the viewer who is at a minimum distance from the screen sees two adjacent pixels connected at one point.
It is worth paying attention to the quality of LEDs, here two indicators are taken into account: durability of operation and time between failures.
Types of LED screens
Depending on the construction method, there are three possible types of street screens: clusters, LED arrays and SMD installations.
Clusters are a group of diodes enclosed in an insulated case — it is usually filled with compound. Each grouping is called a cluster. Each cluster has a connection to its own board, used by the wiring harness. Cluster-type outdoor screens are used less often today and are getting replaced by more high-tech installations.
The LED matrix is different in that the cluster in it is connected to the board as a single element. A matrix is a segment consisting of a control system, diodes, switches and flooded with compound. Matrix screens are much easier to assemble, unlike cluster screens. Matrix screens have a longer operating life and are mostly resistant to the impacts of harsh weather conditions. The most primitive option is the LED display, which you can read about in this article;
The design was improved and LED screens became even more functional: SMD elements were used – these are so-called electrical radio elements, which are mounted directly on the surface of the board. Simply put, these are the same LEDs, but they are fundamentally different in assembly with lamp-type diodes, thanks to them the process of designing matrices became fully automated and the manual method of assembling them was excluded — That was the reason that sometimes products with low quality were obtained. This method of manufacturing screens gave the opportunity to install LED monitors with a small resolution inside the premises.
