CSGtech’s bright idea optimises architectural light housing seal

Modern lighting designs, in residential, commercial and industrial applications, require a blend of architectural elegance and durable performance.

One often overlooked element of a light’s aesthetics, is the sealing materials used in the housing. If an unsuitable material is selected, it may result in dust or water ingress, or light leakage that can ruin the beautiful aesthetic it has been installed to create.

Mood lighting (such as this generic subject) depends on careful engineering to produce the enduring aesthetic required

Problem solving engineer Vinh Lam, General Manager of CSGtech component solutions, says the key to performance is selecting the right material for each unique application.

CSGtech manufactures precision components to solve complex problems where sealing and interfacing components must achieve durability, reliability and precision. Such was the case recently when an Australian manufacturer of architecturally designed lighting solutions was seeking, within a tight timeframe, a sealing gasket for a new light housing prototype.

“This lighting manufacturer placed a high importance on aesthetics, and their end customers were expecting a high quality product,” said Mr Lam. “Part of the challenge when specifying the right sealing component, was to ensure no light leakage through the sides of the housing – a glowing gasket certainly wouldn’t fit in with their aesthetic!” he said.

In addition to aesthetics, the client also needed a durable product, so the material needed to have Ingress Protection rating, IP66, which specifies water and dust resistance properties.

“These requirements are common to a broad range of architectural technologies, where manufacturers want to ensure their products are reliable, durable and add to the desired aesthetics of the building or facility,” said Mr Lam.

CSGtech lights the way

CSGtech began testing and developing different material solutions to meet the unique requirements of this application, and provide a reliable, long-lasting solution. The final solution was a sealing gasket made from closed cell foam with chemical resistant properties, which met the IP66 and all other requirements.

“The sealing gasket was designed with adhesive on one face and a clamp on the other side. The client requested this design because it’s easier for servicing in the future. For a permanently installed item, double-sided adhesive would be used,” explained Mr Lam.

To ensure the client was totally satisfied with the solution, CSGtech hand cut the material to exact specifications and delivered prototypes on a tight deadline.

“The client was very happy with our customised solution. It provided the standards compliance properties, whilst ensuring durability and aesthetics were maintained,” said Mr Lam.
