Outdoor advertising is a type of advertising. Many businesses now choose outdoor advertising as a standard method. To achieve better results, outdoor LED billboards are generally installed with various lights to ensure visibility even at night. However, the installation of lighting must be reasonable, taking the surrounding environment into consideration. Only in this way can it benefit the advertiser without affecting others. Outdoor LED billboard lighting mainly refers to LED lights. Based on the size of the outdoor LED billboard: 1. "S" type sign - Billboard area exceeds 250 square meters, such as super-large advertising towers located on large rooftops and roadsides; 2. "B" type sign - Billboard area is between 21 and 249 square meters, such as medium-sized billboards on rooftops, building sides, and single-pillar billboards; 3. "P" type sign - Billboard area is between 1 and 20 square meters, such as pedestrian walkways, lamppost light boxes, telephone booths, and bus shelters. The use of outdoor LED billboards is now quite common. They are generally installed in areas with high traffic volume. When using lighting in these areas, the first consideration is whether it will cause any inconvenience to passing vehicles. Some lighting installations are unreasonable, illuminating not only the billboard but also the road surface and passing vehicles and pedestrians, creating a safety hazard. Bright lights ahead can temporarily impair vision and make it difficult to see the road conditions, increasing the risk of traffic accidents. When installing lights, it is best to illuminate from the bottom right upwards, avoiding reflection. The lights only need to illuminate the billboard; there is no need for excessive brightness. Downward illumination or scattered light is strictly prohibited. There are also requirements for the type of lights used. It is better to use lights with a yellowish color. Incandescent lights and other high-intensity lights should be avoided, and flashy lights should not be used. The use of lighting for outdoor LED billboards should not harm the interests of others, nor should it disregard other factors for the sake of profit. Reasonable planning is essential before installation.

What is a flexible LED module? A flexible module is different from a conventional LED display module. Conventional modules are made with rigid PCBs and casings, lacking flexibility. They cannot be used on curved surfaces or require special processes like cutting corners, which increases costs and compromises aesthetics. Flexible LED modules were developed to address these issues. Also known as flexible LED screens or soft LED screens, they offer high flexibility, foldability, and bendability. Flexible LED modules operate similarly to conventional LED displays, but utilize flexible PCBs and casings, resulting in exceptional flexibility and the ability to fold up to 120 degrees. Where are flexible LED modules used? 1. Curved Screens: While relatively easy to manufacture for screens with slight inward curvature by creating a curved steel structure for conventional indoor modules, those with large inward or outward curvature require flexible LED modules. 2. Cylindrical Screens: Many hotels, conference rooms, and bars use cylindrical pillars as display surfaces to enhance decor or atmosphere with special video. Flexible LED modules are ideal for this type of application, while conventional screens would be very complex. 3. Wave, Ribbon, and Other Special Shapes: Many designers incorporate wave and ribbon shapes. Flexible LED modules provide a solution that has been difficult to achieve with traditional LED display manufacturing. Flexible LED modules offer many applications, primarily using their high flexibility, foldability, and bendability. Any design idea that can leverage these features is suitable. Dongxian Electronics provides comprehensive display system solutions.

The LED display screen control card receives image display information from the computer's serial port, places it into the frame buffer, and generates the serial display data and scan control timing required for the LED display screen using a partitioned drive method. The LED display control system (LED Display Control System), also known as the LED display controller or LED display control card. LED display screens primarily display various texts, symbols, and graphics. Image display information is edited by a computer, pre-loaded into the frame buffer of the LED electronic display screen via the RS232/485 serial port, and then displayed screen by screen in a loop. The display methods are diverse, and the display screen operates offline. LED display screens are widely used in various industries due to their flexible control, ease of operation, and low cost. Several commonly used control cards are: AT-2 type control card, AT-3 type control card, AT-4 type control card, AT-42 type partition card. LED display control systems are divided into: Asynchronous LED display control system. The asynchronous LED display control system, also known as the offline LED display control system or offline card, is mainly used to display various texts, symbols, graphics, or animations. Image display information is edited by a computer, pre-loaded into the frame buffer of the LED display screen via the RS232/485 serial port, and then displayed screen by screen in a loop. The display methods are diverse and varied. Its main characteristics are: simple operation, low price, and wide range of applications. Simple asynchronous control systems for LED display screens can only display digital clocks, text, and special characters. The LED electronic display screen text and graphics asynchronous control system, in addition to the functions of the simple control system, has the greater characteristic of being able to control the screen content in zones, supporting analog clock display, countdown, images, tables, and animation display, and has functions such as timed on/off, temperature control, and humidity control. Synchronous LED display control system. The synchronous LED display control system is mainly used for real-time display of video, text and graphics, and notices, mainly for indoor or outdoor full-color LED large screens. The working method of the LED display screen controlled by the synchronous LED display control system is basically the same as that of a computer monitor. It maps the image on the computer monitor in real-time on a point-to-point basis at an update rate of at least 60 frames per second, usually with multi-gray-level color display capabilities, achieving multimedia advertising effects. Its main characteristics are: real-time, rich expressiveness, relatively complex operation, and high price. A set of synchronous LED display control systems generally consists of a sending card, a receiving card, and a DVI graphics card.

How to implement fire prevention measures for LED displays? Fire prevention technology for LED displays is closely related to fire-resistant raw materials and cabinet technology. Fire-resistant raw materials include four layers: wires and power supplies used inside the LED display, fire-resistant materials for the external safety protection structure, and plastic components. 1. In most LED display applications, the larger the display area, the higher the power consumption, and the higher the requirements for the stability of the wire's power supply. Among numerous wire products, only wires that meet national standards can ensure safety and reliability. There are three requirements: the core is a copper conductive carrier, the cross-sectional area tolerance of the core is within the standard range, and the insulation and flame retardancy of the rubber covering the core meet the standard requirements, unlike ordinary copper-clad aluminum wire cores. Wires with small core cross-sectional areas and insufficient insulation rubber grade have relatively stable power performance and are not prone to short circuits. 2. UL-certified power supply products are the best choice in the industry. Their reasonable conversion rate ensures the safety and stability of the power load and allows them to operate normally in high-temperature external environments. 3. For the materials of the external safety protection structure of LED displays, most display products with high fire resistance on the market are fire-resistant aluminum-plastic panels. They have excellent fire resistance, flame retardancy, and the core special material has strong oxygen aging performance, a melting point of 135, and a decomposition temperature of 300. They have good environmental performance, are UL94 halogen-free, and meet SGS standards. Their flame retardancy is B-S1, d0, t0. Referencing usage specifications, the aluminum-plastic panels of ordinary outdoor display products age rapidly under high temperatures and rainwater impact. In relatively humid climates, rainwater and dew easily penetrate the screen, causing short circuits and fires. 4. Among the raw materials for fire-resistant LED displays, plastic components are a key part. Plastic components are mainly used as raw materials for the unit module mask bottom shell. The key raw material is flame-retardant PC glass fiber material, which not only has flame-retardant properties but also does not deform or become brittle during high and low temperatures and long-term use, is not easily cracked, and can be directly combined with glue with good sealing performance to effectively prevent rainwater from entering the inside and causing short circuits and fires. 5. Without breakthroughs in key raw materials such as LEDs, increasing current does not improve brightness. In addition to internal raw materials affecting the actual effect of fire prevention, external configurations and designs are equally crucial. External configuration key points include fire prevention in terms of heat dissipation. When the display is working, exhaust fans and air conditioners will be configured to dissipate heat inside the screen. It is recommended to install one 1P air conditioner every 8-10 units in the square assembly line to ensure that the temperature inside the screen remains consistently normal. Improper configuration of air conditioners or exhaust fans, uneven heat dissipation, can easily lead to safety hazards due to increased temperature inside the screen body. Furthermore, many LED display companies only simply simulate environmental factors in spray waterproof testing when testing the protection level of the cabinet. The durability and strength of the actual waterproof effect need to be verified, leading to water seepage after the display product has been used for a period of time. This is also a key reason why outdoor displays are very prone to fire or have a short lifespan. To cope with the temperatures of thunderstorms, surge arresters for screen equipment are necessary to prevent lightning strikes and burning of internal components, and also to prevent lightning from entering the ground and damaging the screen. 6. Correct installation Because the electronic components of full-color LED displays are mainly made of combustible materials, to fundamentally prevent combustion, high-quality power supplies, wires, ICs, and connectors should be used.

Outdoor LED advertising billboards have advantages such as good stability, low energy consumption, and wide radiation range, making them the most suitable product for outdoor information dissemination. Common LED displays generally include advertising screens, strip screens, and graphic screens, which are also the preferred choice for city life and lighting. When building high-quality outdoor LED advertisements, there are some important details to pay attention to. These are key concerns, especially for technical construction personnel. Understanding outdoor construction and maintenance of advertising screens effectively promotes the dissemination of business advertising and information. Specifically, the installation of outdoor LED electronic display screens involves four stages: on-site investigation, equipment setup, installation, and commissioning. 1. On-site Investigation This refers to the pre-installation testing of outdoor LED display screens for specific environment, topography, radiation range, and brightness acceptance. To ensure smooth installation, a unified lifting plan must be implemented for the command personnel before lifting and installation to guarantee normal and stable operation of the equipment. 2. LED Equipment Setup For outdoor LED advertising screens, it is necessary to differentiate between wall-mounted, suspended, and rooftop screens. During actual installation, depending on the height and distance, cranes and winches should be used for section-by-section hoisting, ensuring coordination among personnel. For high-altitude LED advertising screens, a better installation process should be followed. 3. Radiation Range Adjustment Next, radiation range detection is carried out. Since the radiation range varies, the viewing angle of the LED display screen also varies. The outdoor LED display screen should be fixed according to the on-site acceptance capacity and common viewing range. This ensures normal and evenly bright images and subtitles are visible from all angles. 4. Subsequent Inspection and Maintenance Subsequent inspections cover many aspects, such as waterproofing of the LED display screen, heat dissipation layer, LED surface waterproof coating, rain protection above the display screen, side heat dissipation spaces, power supply lines, etc. These basic components constitute a stable graphic LED display screen. Post-technical maintenance involves unified management and maintenance of these components. When rust, instability, or damage occurs, timely replacement is necessary to ensure safe operation of the entire display screen. Overall, outdoor LED advertising screens, using high-tech backplane heat dissipation and dot matrix light source emission, are more conducive to screen use. These basic outdoor advertising screen installation steps highlight the important aspects of LED display screen installation. Understanding these steps allows for smoother and faster use of the advertising display screen, maximizing its excellent information dissemination capabilities.

However, LED lighting fixtures are high-tech, high-value-added products. China's previous research on LED lighting has been limited, with a significant gap compared to international levels, especially in application-based research, which cannot meet the needs of China's industrial development. II. LED Full-Color Display Testing Content: 1. Radiation Bandwidth: The wavelength range where the spectral radiant power is greater than or equal to half of its value. 2. Half-Intensity Angle: In the luminous (or radiant) intensity distribution, the angle formed by the luminous (or radiant) intensity greater than or equal to half of the maximum intensity (LED light). 3. Reverse Current: The current flowing through the light-emitting diode when the reverse voltage applied across the light-emitting diode is a predetermined value. 4. Forward Voltage: The voltage drop across the anode and cathode when the forward current passing through the light-emitting diode is a predetermined value. Summary: In today's information society, with continuously improving living standards, the demand for full-color LED displays is also increasing.
