Luminous character signs face multiple challenges in outdoor environments, such as direct sunlight, rain erosion, temperature changes, etc., all of which may affect their durability and service life. In order to ensure the durability of luminous character signs in outdoor environments, it is necessary to start from multiple aspects.First, the choice of materials is crucial. High-strength and weather-resistant materials should be selected, such as metal materials such as stainless steel and aluminum alloy, and special coating materials. These materials can resist the erosion of natural environments such as sunlight, wind and rain, and maintain the integrity of luminous character signs. At the same time, acrylic sheets or PC sheets with good light transmittance and strong impact resistance are also ideal choices for making luminous character signs, which can ensure that the brightness and appearance of the luminous characters are not affected.Secondly, reasonable structural design is also key. The internal structure of luminous character signs needs to be carefully calculated and designed to withstand external forces such as wind load and self-weight. The use of a sturdy frame structure, such as reasonable keel arrangement and support point setting, can effectively disperse the force and reduce the risk of deformation and damage. At the same time, the effects of thermal expansion and contraction should be taken into account, and appropriate expansion joints should be reserved to avoid structural rupture due to temperature changes.In addition, waterproofing and heat dissipation treatment are also important factors to ensure the durability of luminous character signs. Rainwater and humid air in outdoor environments can easily invade the interior of luminous characters, causing circuit failure and corrosion. Therefore, effective waterproof sealing measures need to be taken, such as using high-quality sealants and waterproof gaskets to ensure that the interior of the luminous characters is dry. At the same time, luminous characters generate heat when working. If the heat is not dissipated in time, it will affect the life and luminous effect of the lamp. Therefore, it is crucial to reasonably design ventilation holes and heat dissipation channels.Finally, regular maintenance and inspection are also important means to ensure the durability of luminous character signs. A regular maintenance plan should be formulated, including cleaning the surface of the luminous characters, checking the stability of the fixed parts, and promptly repairing damaged or faded parts. Through these measures, the service life of luminous character signs can be effectively extended to maintain their stable performance and attractiveness.
