| 主权项 | 1. A lighting apparatus comprising: a heat sink comprising a forward surface and a central axis that is substantially perpendicular to the forward surface, a first fin section having a plurality of radial fins with a first length and a plurality of radial fins having a second length, the plurality of radial fins being substantially parallel to the central axis and extending radially outward from the central axis, wherein the first length is greater than the second length, and a second fin section with a plurality of radial fins having a third length and being substantially parallel to the central axis and extending radially outward from the central axis, wherein the third length is different from the first length and the second length; and a light engine coupled to the forward surface of the heat sink. | ||
