An optical sheet with a structured surface profile performing as secondary optics for LED lighting devices. The optical sheet is manufactured with a structured profile, like fresnel lens type, on its surface but leaving a flat portion in the centre of the optical sheet which does not possess the structured profile. ...
An optical system comprising of bi-cylindrical lens(2) and lens array(l) for a distant area illumination pattern control is disclosed. The lens array(l) is comprised of individual bi-cylindrical lenses (2), with controlled structural parameters: Front Surface Curvature (FSC), Back Surface Curvature (BSC), front cyli...
An architecture for an LED and a method to fabricate this architecture are proposed. The method relates to a 3D geometry for the LED die. Semiconductor layers like u-GaN, n-GaN, multiple quantum wells and p- GaN, are sequentially grown over a substrate. The top surface of the p- GaN layer is etched using Photo litho...
