LED light bulbs are increasingly being used by people all over the world as they are an energy-efficient way of illuminating the home.
However, a company in Cambridge claims to have found a new way of cutting heat even further in LED ceiling light fittings.
Indeed, Cambridge Nanotherm has launched a new design of metal-backed PCB made from a ceramic dielectric which, it claims, can significantly reduce LED temperatures in luminaire designs.
The firm converts aluminium into alumina - Aluminium Oxide - which allows the surface of it to be converted into a layer of alumina that acts as a dielectric, which is an electrical insulator.
According to the company, tests in LED ceiling spotlights show that it offers a 20 per cent reduction in substrate thermal resistance, Electronics Weekly reports.
Nanotherm's head of product development Steven Curtis told the news provider that this substrate material will offer an alternative to designers that need the excellent performance of Aluminium Nitride in their packages, while meeting tight cost targets.
The company sees the material as an important addition to its customers' material toolboxes.
Chief executive officer and founder of Cambridge Nanotherm Dr Pavel Shashkov commented: "This nano-ceramic dielectric not only provides excellent electrical isolation, but also has a thermal performance which is much improved over the standard filled epoxies used for conventional thermal management dielectrics."
This news comes after scientists in Belgium, France and Canada claimed to have found ways to modify LED light bulbs that are one and a half times more efficient, after being inspired by the twinkling of fireflies.
Indeed, they believe they have made a substance to cover LED light bulbs that makes them much more energy efficient than the current illuminations are.
