New large LED light engines simplify design and enhance performance of panel lighting designs

Universal Science has announced the introduction of large LED light engines that can be manufactured up to 600mm x 600mm in size. Capable of providing a fully integrated, low-profile, single-board solution with zero interconnects, they offer an approach that has significant design, thermal, and light benefits, plus mechanical and electrical reliability advantages, compared to existing approaches.

Versus multi-board, LED edge lit, and traditional compound fluorescent (CFL) assemblies, the innovative new technology enables greatly simplified designs including a reduction in the assembly’s weight and offers highly efficient panel lighting in both commercial and industrial settings. A 560mm x 560mm version of the light engine is fully compliant with the Zhaga standard, and the size and shape options available to luminaire designers is almost limitless with board lengths up to 1.2m possible.

The new large light engines from Universal Science utilise a single insulated metal printed circuit board (IMPCB) making them both lightweight and durable. The substrate itself is employed as the housing / back of the luminaire for the panel light alleviating the need for complex, heavy and space consuming gear trays and associated fixings and other hardware. This results in a major reduction in the bill of materials for an assembly and will speed and ease installation.

A further benefit of simplified designs with minimal fixings and complexity is the potential to completely seal the assembly. This can be especially important in challenging environments with perhaps, high humidity, or installations in hospitals for example.

An array of low power LEDs – up to 700  for a 600mm x 600mm light engine – can be mounted on the IMPCB directly behind the luminaire diffuser lens. The large array gives evenly distributed light and is 40 to 50% more efficient compared to edge lit designs where light loss is an issue. Using multiple low power LEDs also minimises thermal management problems, and with the whole assembly running cooler, reliability and life expectancy are optimised.

Universal Science light engines can run on single or multiple circuits bringing flexibility and control to lighting configurations. RGBW combinations are possible as are varying colour temperatures and dimming.
