ProPhotonix announces Patent Application for Optical Module Heat Sink Array
Scalable, water-cooled heat sink array for precise orientation of optical modules

(Salem, New Hampshire, May 14, 2015) ProPhotonix Limited (OTC: STKR and London Stock Exchange - AIM: PPIX and PPIR), a designer and manufacturer of LED illumination systems and laser diode modules with operations in Ireland and the United Kingdom, today announces that it has filed a patent application on its unique heat sink for optical modular array assemblies.

The invention is a water-cooled heat sink design suitable for a range of different optical module arrays and sizes that allows for easy replacement of individual optical modules. Design features include precise orientation of the optical modules to ensure an exact electrical connection to an external driver circuit. In addition, the thermal management capacity allows a large density of optical modules, which enables high optical output for many applications.

The invention allows for easy removal and replacement of modules in the field by non-technical personnel, thus alleviating the need for skilled technicians for repair. Importantly, the heat sink has been designed to ensure that the "back end" of the optical module (e.g., the end of optical module where the emitter is located) is circumferentially orientated within a given opening. This allows for light sources of optical modules to be precisely connected to an external circuit every time, even when optical modules are being replaced. In conjunction with optical modules, typical applications for this invention include computer-to-plate printing, maskless lithography and laser marking.

Tim Losik, CEO & President, ProPhotonix, stated" This patent application serves as a reflection of ProPhotonix' continued progression and leadership in developing technology-driven solutions. The design and features of this thermal management device are modular, scalable, and importantly allow for easy field repair with precision "plug and play" alignment of optical modules. We are constantly developing new and unique capabilities, and ProPhotonix will continue to pursue additional patent applications resulting from our technical development initiatives."
