Incorporation of Light Emitting Diodes in the Clothing

The integration of Light emitting diodes in the textile products allows assign additional functions, such as the visibility on the street, or may serve as a fashion design. During the conductive system integration in the textile structures there should be find the solutions for approximation of both electronic and textile physical characteristics (for example, flexibility, elasticity etc.). The aim of this research is to analyze integration possibilities of light emitting diodes in the clothing. Depending on the type of light-emitting element and their construction, there are designed a variety of integration and incorporation technologies; some of them are summarized in the table 1. Using the solder method, there are getting a high-quality, reliable electrical connections, where the connection point is durable and it has a good electrical conductivity, however the mechanical properties are not suitable for textile characteristics - it is not flexible and is subject to breakage and disconnection of electrical circuit. The using of conductive adhesives is more suitable than soldering method, since they conduct the electricity very well, are durable and flexible, they comply with a folding of textile and cover electronics parts. Popular and appropriate method for electronics incorporation in the textile is attaching by sewing, using conductive threads. In such way created sewn LED provides a good connection with the sewn circuit integrated in the clothing fabric, due to the enough wide conductors, while 3-dimensional foot material protects the LED of mechanical defect potentialities and provides a necessary stability for electrical circuit
