Lighting Design & Specification

Litecool Lumen BlocksThe new package enables the assembly of LED arrays with no circuit board, putting the LED package directly on the heat sink for ultimate thermal performance and cost reduction. The package will be available soon, says the company.

Litecool’s Lumen Block is an LED package that doesn’t require any circuit board enhances performance and reduces costs for luminaire manufacturers. The package can connect directly to the next LED package without the need for a circuit board to hold it or provide connections. They can be placed directly onto a heat sink and automatically clip together forming mechanical and electrical connections. That means no soldering, no PCB and direct thermal connection to the heat sink.

This technology removes the need for PCBs and SMT assembly. Litecool takes bare chips from die manufacturers and puts them in their package, which they supply direct to luminaire manufacturers who can then simply place them on their heat sinks. This shortened supply chains means the system is more easily optimized for specific applications, reduces time to market for new products and reduces costs.

“Instead of trying to reduce the thermal resistance of an individual component in a system we ask ourselves why these components were in the system at all,” explains Elwyn Wakefield, Chief Packaging Engineer, Litecool. “By removing the circuit board form the system we can optimize cost and performance.”

The Lumen Block will be available with a variety of LED die inside giving a choice of performance. First product will be a 10mm x 10mm package containing a Cree Gen 3 LED capable of nearly 150 lm/W. The packages will fit standard optics from Carlco giving a range of high efficiency beam patterns.
