Plessey Integrates Optics into GaN-on-Silicon CSP LEDs

Plessey announced that it has developed a patented technology for Chip Scale Optics (CSO) based on its award winning GaN-on-Silicon MaGIC ™ LEDs.  Chip Scale Optics permits design of light emission angles down to ten degrees direct from the LED.  Having the primary optics on-chip eliminates the cost of primary optics typically found in packaged LEDs and chip-on-board modules.  Furthermore, it significantly lowers the cost and provides for far greater design freedom for secondary optics within a luminaire.  The first off applications include retail spot lighting, hospitality lighting, high and low bays, street lighting and stadium lighting.  It is estimated that Plessey’s chip scale optics will halve the cost of these lighting applications.
