A solid state light sheet and method of fabricating the sheet are disclosed. In one embodiment, bare LED chips have top and bottom electrodes, where the bottom electrode is a large reflective electrode. The bottom electrodes of an array of LEDs (e.g., 500 LEDs) are bonded to an array of electrodes formed on a flexible bottom substrate. Conductive traces are formed on the bottom substrate connected to the electrodes. A transparent top substrate is then formed over the bottom substrate. Various ways to connect the LEDs in series are described along with many embodiments. In one method, the top substrate contains a conductor pattern that connects to LED electrodes and conductors on the bottom substrate.

A lighting assembly with a single edge lit optical configuration produces various asymmetric light distributions which provide targeted control of light output with peak intensity that is non-normal to the light guide output face. The compact form factor of the lighting assembly embodiments having narrow width are particularly well-suited for use in linear lighting applications requiring suspended, surface and recessed installations typically used to illuminate walls, floors and/or ceilings. The lighting assembly can also be selectively configured and oriented during assembly and installation to achieve various lighting distributions. Optical components within the lighting assembly are typically positioned and retained in optical alignment with internal support features of a linear housing. The optical configuration typically includes LED board, light guide, and one or more reflectors, and an optically transmitting component providing further control of the lighting distributions and a broader range of design choices. A variety of asymmetrical and symmetrical light distributions can be achieved with one or more peak intensities. Further embodiments utilize selective alignment of the light guide with one or more reflectors to achieve different light distributions.
