Energy saving is a hot topic globally; there has been a significant shift in businesses and consumers striving to reduce carbon footprints and energy costs. As a result, there has been an increase in the use of LED lighting, which creates some additional challenges for designers such as thermal management. Adhesive material manufacturers have responded to these needs by offering a wide range of materials that enhance the efficiency and lengthen the lifespan of lighting products.
Parafix has been a supplier into the lighting industry for a number of years and understands the evolving needs and challenges of this market. We work with world leading lighting manufacturers, designing and manufacturing bespoke components from a wide variety of high performance materials.
There are a number of opportunities to use an adhesive tape, film, foil or foam to reduce the weight of your lighting product, enhance its efficiency, extend its lifespan and reduce the cost of manufacture. These can be seen below.
Our adhesive materials for lighting include:
Heat/flame resistant bonding materials are a vital component of LED lighting due to the high temperatures generated. High temperature tapes resist this heat and ensure the long term holding of lighting systems, for extended lifespan and reliable bonding. They are lightweight, offer a clean finish, will bond various substrates and seal as well as bond in one operation.
As with all electronic products, sealing is vital to protect internal components, to enhance the lifespan of the product. Adhesive bonding tapes offer a trusted solution to sealing indoor and outdoor lighting products from environmental contaminants such as dust, debris and water, whilst also allowing for differential thermal expansion of substrates. Our foam bonding products can also dampen sound and vibration e.g. in automotive lighting. These products can make your lighting systems more durable and can eliminate the need to add protective coverings.
Exposure to daily and seasonal changes in temperature causes the air inside lighting enclosures to expand and contract. The resulting pressure differentials can cause seals to fail, allowing water and other contaminants to enter the enclosure. Pressure differentials can also be caused by altitude and thermal shock e.g. exposure to rain and snow. Other challenges include the level of humidity within the enclosure; this can generate condensation which will compromise the electronics and reduce the LED effectiveness, as well as the aesthetic quality.
The solution is to incorporate a protective vent that allows air to flow freely in and out of the luminaire, whilst preventing the contamination of water, dust and debris. This equalizes the internal pressure and protects components, ensuring the LED remains effective and durable.

Thermal management for lighting applications
Today’s high intensity LEDs generate more heat than conventional LEDs, both of which require effective thermal management to transfer or sink the heat they emit. This ensures they can operate to optimum performance. Our thermal management materials offer a cost effective solution that will extend LED lifespan and provide a lightweight heat management solution for a smaller and lighter end product. These high performance cooling materials have a proven track record of durability in the most demanding applications and environments.
Highly reflective Micro cellular (MCPET) foams and light enhancing films offer a light weight solution for improved energy efficiency in LED or fluorescent light fixtures and signage. These products improve the visual impact of light by balancing blue and red light reflection equally. The result is an increase in light output using less energy and a lighter end product, without the need for additional manufacturing equipment or lighting components. Neon tubes, fluorescent tubes and LED lights can often be reduced by 50%, resulting in lower component costs and energy consumption.
Uniformity tape is a light mixing product that provides a solution to some of the constraints in edge lit LED lighting. The microstructured thin film diffuses light generated by LEDs, reducing dark zones and improving brightness uniformity by inducing lateral light spreading in the plane of the light guide. The benefits of the uniformity tape include a reduction in the number of LEDs used, whilst maintaining the same light output, and the light mixing near source is more evenly distributed.
