Patent ID: 7938559

Claim:
A multiple optical assembly for a LED lighting device, comprising: three modular units, each modular unit having a single lens associated with a respective LED, and connecting means for connecting the modular units to one another and maintaining the lenses in predetermined positions with respect to one another, the lenses being defined by respective curved lateral surfaces defining respective distinct optical surfaces which are reflecting surfaces for transmitting light internally to each lens between two opposite ends of the lens, wherein the optical assembly formed by the three modular units has, at an axial end, a substantially circular peripheral end edge, and in plan view the lenses are inscribed in the peripheral end edge, which is defined by respective consecutive edge portions of the modular units, and wherein the curved lateral surface of each lens has two beveled surface portions, and adjacent lenses are positioned with the respective beveled surface portions facing and contacting each other, each lens of said assembly contacting the other two lenses at the beveled surface portions.
