A light unit that includes an internal power supply that may be used in the event of an external power failure to provide power to the light unit. In one aspect, the present disclosure provides a lighting apparatus, comprising (a) a power input configured to receive external power from an external power source; (b) a solid state light element that is interconnected to the power input; (c) a detection circuit interconnected to the power input and that, when power is not provided to the power input, measures input impedance at the power input and determines if there is a lack of external power; and (d) a back-up power source that is interconnected to the solid state light element and the power input and that provides power to the solid state light element when the light element is; not provided with power from the power input.

Light unit with internal power failure detection

A lamp assembly manages thermal energy output from solid state lighting elements. An aspect of the present disclosure provides a lamp assembly that achieves enhanced cooling of light elements within the assembly. Enhanced cooling is achieved, in this aspect, by providing a lamp assembly including a heat sink having a plurality of thermo bosses protruding therefrom on a first side, and a plurality of heat sink fins on a second side. A printed circuit board is secured to the first side of the heat sink, and has a plurality of through holes that correspond to the size and locations of the thermo bosses, such that when the printed circuit board is secured to the heat sink, the thermo bosses extend into the through holes.
