An optical device includes a lower surface that is substantially transparent. The optical device further includes an upper surface disposed opposite the lower surface and having a first specular layer disposed thereon. The optical device further includes a first lateral surface extending between the lower surface and the upper surface and having a second specular layer disposed on at least a portion thereof.

A lighting device for use with one or more other networked devices is disclosed. In embodiments, the lighting device may comprise an outer globe, a diffuser, an outer cowling, a power input connector, a power control printed circuit board, a communication and control printed circuit board, an indicator printed circuit board, one or more microprocessors, a real-time clock, a supercapacitor, and an LED lighting printed circuit board. In embodiments, the real-time clock may be powered by the supercapacitor to track time without power from an input power source for the lighting device, enabling the lighting device to implement time-dependent settings, such as pre-programmed color temperatures and/or light intensities. The lighting device may communicate with one or more other networked devices, such as second lighting devices, mobile phones, servers, remote controls, and/or home or office automation equipment. The lighting device may be powered through a light socket.

The present disclosure provides an LED based light unit that produces an output lighting pattern that meets desired lighting characteristics using a reduced number of LED elements. The present disclosure provides a number of point sources that are directed into a desired direction such that, when combined with other point sources, a synthesized light output is provided that minimizes the LED headcount.
