Whether it's for automotive headlights, in greenhouses, or for offices and homes, LEDs have gained acceptance in almost all fields of lighting applications. This is because, in addition to their low energy consumption, LEDs are also very versatile. However, this often requires integrating additional electrical and electronic components into the LED luminaires. For this purpose, Wevo-CHEMIE GmbH offers tailor-made potting compounds, gels, adhesives, and sealants that also satisfy additional requirements such as protection against environmental influences, heat, and chemicals.

The demands on lighting are manifold and nowadays go far beyond classical aspects such as safety. Among other things, factors like easy adaptability to ambient conditions, integration into smart applications, or the technical possibilities for further development play an important role. State-of-the-art lighting systems, for example, can precisely create the mood people are looking for – whether they are at home, at work, or in their car. In greenhouses, plant growth is promoted by creating lighting conditions with specific wavelengths ("horticultural lighting"). On the roads, intelligent lighting systems automatically adapt to approaching vehicles or pedestrians.

Technically, this means that LEDs and electronic components need to be integrated into the luminaire and protected against environmental influences in order to guarantee a long service life. In addition, electrical insulation is another important aspect essential to protect users and electricians from hazards and to avoid short circuits and fires. The development of smart and networked systems, as well as new technologies such as Li-Fi (light fidelity), also demands additional components, including sensors, antennas, transformers, drivers, and IoT devices. These are increasingly being integrated directly into the luminaire itself rather than realized as an external component.

With its tailor-made materials based on polyurethane and silicone, Wevo is actively facilitating these developments in LED lighting systems – and the products can be used in a wide variety of applications (Fig. 1).

Fig. 1: Possible applications of Wevo materials in the lighting industry

Regardless of the application, the use of potting compounds, adhesives, and sealants brings benefits in terms of design, the manufacturing process, and product longevity, and solves among other things the following challenges that arise with respect to lighting engineering.

CHALLENGE: ENVIRONMENTAL CONDITIONS

Potting compounds, gels, adhesives, and sealants from Wevo can be used both indoors and outdoors. Thanks to special ingredients used in their production, LED luminaires (including LED strips) are reliably protected against environmental influences such as ultraviolet light, humidity, dust, or corrosive gases. The materials, which are based on polyurethane and silicone, can be used for interior luminaires as well as for street lamps, architectural lighting, or illuminated advertising systems.

When light sources are used in hazardous or safety-critical environments, such as chemical plants, tunnels, or airports, they are subject to high requirements in terms of resistance to a wide range of environmental conditions. These include, for example, chemicals, explosive gases, salt, weather, or insects. The use of hydrolysis-resistant and hydrophobic polyols with low hygroscopicity and special UV-resistant isocyanates in the hardener component ensures both reliable protection and electrical insulation even in such cases.

CHALLENGE: FOGGING

For use in automotive headlamps and rear lights, Wevo has developed special adhesives and sealants that prevent tension cracks in the housings as well as fogging. To achieve this, the compatibility of the materials with amorphous plastics such as PC and PMMA was adjusted. In addition, they consist of particularly pure and solvent-free raw materials.

CHALLENGE: OPERATING TEMPERATURES

Another challenge is high operating temperatures, as in the case of high-power LED spotlights for theatre stages and closely packed LED luminaires for greenhouse lighting. In these cases, the special heat-conducting potting compounds and gap fillers provide reliable protection for the components and LEDs. Effective heat dissipation from the LED modules to the heat sink and ultimately to the ambient air is ensured by the use of special thermally conductive fillers in the potting compound or thermally conductive paste.

Wevo Developed Silicones and Polyurethanes with a Lower Hydrogen Permeability Used as Adhesives and Sealants for PEM fuel cells

Wevo’s polyurethane sealants, which have similar thermo-mechanical properties to silicones, have even lower hydrogen permeability depending on the Shore hardness setting. Their permeation coefficients vary between about 30 and 70 E-8 cm²/s, also after a 16-hour measurement period.

Wevo Potting and Sealing Compounds Pass the Endurance Test, Protected Redox Flow Batteries From the Corrosive Electrolyte

Redox flow batteries are elaborately constructed wet-cell batteries in which electrolytes, often based on vanadium, are circulated by means of pumps. The technology is seen as having great potential as a storage system for renewable energy from solar photovoltaic and wind farms or rooftop systems. However, the design of the battery stacks has been a real challenge so far as the aggressive electrolytes may cause stress on the materials.
