In the field of modern lighting and sign technology, LED light characters are widely used in various scenarios, from outdoor commercial signs to brand logos inside shopping malls, for their high efficiency, long service life and superior visual effects. In the production process of LED light-emitting characters, the heat-resistant hot-melt adhesive rod plays a crucial role in the fixing of the internal lamp harness and the splicing of light-emitting characters components.

First, the needs and challenges of LED light word production

The interior of the LED light word contains complex electronic components and components, of which the fixing of the lamp harness is the key to ensure its normal operation. The lamp belt itself needs a stable fixed position to prevent displacement due to vibration, thermal expansion and contraction during the use of the luminous word, which affects the uniformity of the light and the luminous effect. At the same time, the splicing requirements between the various components of the luminous word are also extremely strict, which needs to ensure the firmness of the splicing without affecting the overall aesthetics and structural stability. In addition, because the LED luminous characters will emit heat when working, this poses a challenge to the high temperature resistance of the fixed material.

Second, the advantages and advantages of high temperature resistant hot melt glue rod in LED light internal lamp with wire harness fixing

Excellent bond stability: the high temperature resistant hot melt adhesive rod can be tightly wrapped after melting the lamp harness to achieve strong bonding force. This bonding force will not be weakened by small external forces or long-term vibration, so as to ensure that the lamp strip always maintains a stable position. For example, in the LED light-emitting characters installed in public transportation hubs, such as stations and airports, a large number of pedestrians and vehicle vibrations are experienced every day, but the lamp harness fixed with a heat-resistant hot-melt adhesive stick can still work normally, without loosening or breaking.

Good high temperature resistance adaptability: LED luminous characters will generate a certain amount of heat during the working process, especially in the case of long-term high brightness work. The high temperature resistant hot melt adhesive stick can maintain its own physical and chemical properties in a higher temperature range, and will not be softened, deformed or lose the bonding ability because of heat, thus effectively protecting the fixed effect of the lamp harness.

Flexible applicability: Due to the diversity of LED light word design, the layout of the lamp harness is also different. High temperature resistant hot melt adhesive sticks can be adapted to a variety of wire harness diameters and arrangements. Whether it is a more slender lamp harness or multiple lamp belts combined together, it can be effectively bonded and fixed, which provides great flexibility for the fixing of the lamp harness.

Third, the advantages and advantages of high-temperature hot melt glue rod in the splicing of luminous word components

High strength bonding: High temperature resistant hot melt adhesive sticks have excellent bonding ability for different components of luminous letters, such as metal frames, plastic shells, etc. In the assembly process of luminous letters, the use of this hot melt glue rod can make each component closely connected to form a strong overall structure. In the installation scenario of the outdoor large luminous word sign, it can withstand the test of various external environments such as strong winds and bad weather, to ensure that the luminous word does not have the problem of loose structure during long-term use.

Meet the balance of aesthetic and functional needs: on the basis of ensuring a solid splicing, the high-temperature hot melt glue rod will not affect the appearance of the luminous character. It can be bonded at the same time, keep the surface of the luminous word flat and smooth, so that the luminous word in the visual unity of the overall beauty. At the same time, in terms of function, it will not negatively affect the optical properties such as light propagation and reflection of luminous characters because of the presence of glue.

Improve production efficiency and reduce costs: In the production process of luminous letters, the high temperature resistant hot melt adhesive rod curing speed. When workers paste the light-emitting components, they can quickly complete the operation and move on to the next process, thereby improving production efficiency. Moreover, due to its precise adhesion, the waste caused by the use of excess glue is reduced, which helps to reduce production costs.

4. Application cases and effect witness

In practical commercial applications, many well-known brands of light-emitting lettering signs use hot melt glue sticks to hold the lamp harness and splicing components. For example, brand logos of large supermarket chains, outdoor advertising logos of famous automobile brands, etc. These luminous character signs have been used for a long time and a lot of practice verification, which proves that the high-temperature hot melt adhesive rod plays an important role in ensuring the quality and performance of luminous characters, and provides a reliable guarantee for the long-term stable work and good visual presentation of luminous characters.

In summary, the high-temperature hot melt adhesive rod with its stable bond, high temperature resistance, flexible application and other characteristics, has become an indispensable material for the wiring harness fixation of the LED light internal lamp and the splicing process of the light-emitting word component.
