TECH NOTES: Tesla™ simplifies LEDs for the OEM general lighting market

Sept. 30, 2008
Building on several years of increasingly successful implementation in general lighting sector applications, Lynk Labs has taken its Hybrid AC topology into a chip-level product.
As the emphasis on low carbon impact increases, so the importance of LEDs in lighting grows. Unlike traditional lighting sources, LEDs are DC current devices and whilst their efficacy has now passed even fluorescents, their basic incompatibility with the power infrastructure leads to loss of efficiency and complicates their adoption in many applications.

With AC LED architecture from Lynk Labs, the adoption of an LED based lighting solution becomes as simple as a ‘bulb and ballast’. Simple applications reduce cost and promote adoption by the lighting industry. High efficacy, particularly at the system level which includes the power source, puts AC LEDs ahead of most other solutions.

Building on several years of increasingly successful implementation in general lighting sector applications, Lynk Labs has taken its Hybrid AC topology into a chip-level product. Launched at the LEDs 2008 conference in San Diego, the Tesla™ LED is the first 12V AC Surface Mount single chip light engine. The driving principle behind this evolution has been to simplify the adoption of LED technology into the OEM general lighting sector.

Lighting designers and luminaire manufacturers are faced with many complexities as they develop solid state lighting strategies. Lynk's technology reduces these challenges and complexities by offering true "Plug n' Play" LED lighting system solutions that simplify or improve system integration, reliability, thermal management, weight reduction and lighting system scalability. Tesla does this in a 6.5mm square 1.2W package (the TL6565) which is set to cut through that complex web of design issues.

A common theme at the LEDs conference was the need, expressed by OEMs and Industry specialists alike, to develop architectures which were more compatible with the real world of luminaire OEMs. Put simply, most OEMs want “bulb and ballast” simplicity, not electronic complexity.

Tesla LEDs are designed to enable lighting OEMs to develop end products faster and in more infrastructure-friendly solutions for the general lighting market. They can be scaled easily in 12VAC increments and designed into 12VAC – 240VAC lighting applications and are available in CCT’s of 2700, 3000, 3500, 4000, 4500, 5000, 6300K with a standard CRI of 75 and High CRI in all CCT’s for special orders. Integrators and end users now have access to Lynk Labs AC LED technology in the most simplified LED device design solution available for the general lighting market. This is essentially a 12VAC LED light bulb in an SMT LED package.

Tesla LEDs, like previous XyLite modules deliver flexible X and Y dimensional building blocks of light that enable luminaire and OEM designers to significantly accelerate and simplify their product design strategy for almost any LED lighting application. Adding to this the benefits of Lynk Labs AC LED technology, OEM product designers and engineers can deliver LED lighting products that are Lighting Infrastructure Friendly and better understood by architects, contractors, reps, distributors and End Customers from existing experience with lighting.

In addition to several standard XyLite module configurations which carry the Tesla LED, Lynk will offer the same module design capability as it has with previous AC light engines. Tesla will also be available as a SnapBrite™ system.

SnapBrite is a patented AC LED “light engine system solution” that helps OEMs to simplify inventory, product design, manufacture and sales challenges. SnapBrite can be easily broken down or put back together in production, based on product demand. Supplied as a 12” linear light engine that can snap apart in production to fill multiple lighting applications, it can be broken down into any combination of shorter lengths (in 1” multiples) and is easy to connect back together or into longer than 12” lengths with a novel interconnect system.

SnapBrite provides highly configurable AC LED “Plug and Play” capability for a wide variety of new product and retrofit LED applications. The Tesla LEDs in the SnapBrite system are connected in parallel, offering maximum system reliability while maintaining the advanced flexibility of the SnapBrite architecture.

The next Tesla LED to be released after the TL6565 will be the TL1203. This is a ½ w linear light engine 12 mm long and 3mm wide. Designed to address applications requiring a thin ribbon form factor, this LED will be launched early in 2009. Other Tesla variants will be produced to meet specific OEM requirements in the general lighting sector as they emerge.

Nikola Tesla was the founding father of AC power technology in the 19th century. His visionary work enabled the evolution of economic power generation and distribution which is one of the primary underpinnings of our 21st century civilization. So it seemed fitting to name Lynk Labs’ first major commercial AC powered LED after that great scientist in the hope that its contribution to the adoption of green lighting technology might in some small way reflect the same spirit of unorthodox and pioneering technology application.
