Luminaire with modular cooling system and associated methods

摘要

A luminaire comprising a base, a heat sink modularly connected to the base, and a heat-generating element in thermal communication with the modular heat sink. The heat sink may include a heat-generating element contacting portion, and a plurality of heat sink segments connected to and extending outwardly therefrom. Each of the heat sink assemblies segments may comprise at least one fin assembly. Each heat sink segment may pass through a respective plurality of passageways in the top portion of the base so that the heat sink segments may matingly engage the medial portion of the base. A method for forming a heat sink comprises fabricating a heat-generating element contacting portion, constructing a plurality of heat sink segments, and assembling the plurality of heat sink segments to connect to and extend outwardly from the bottom surface of the heat-generating element contacting portion.

主权项

1. A luminaire comprising:
a base having a bottom portion, a medial portion, and a top portion, the top portion of the base having a plurality of heat sink segment receiving passageways formed therein and the medial portion of the base having a substantially cylindrical walled core inside the base comprising an interior and an exterior; a heat sink modularly connected to the base and comprising:
a heat-generating element contacting portion having a top surface and a bottom surface,a plurality of heat sink segments connected to and extending outwardly from the bottom surface of the heat-generating element contacting portion, wherein each of the plurality of heat sink segments comprises at least one fin assembly; and a heat-generating element in thermal communication with the modular heat sink; wherein the plurality of heat sink segments pass through the respective plurality of heat sink segment receiving passageways so that the at least one fin assembly of each of the plurality of heat sink segments matingly engages the medial portion of the base such that a proximal edge of the at least one fin assembly of each of the plurality of heat sink segments is positioned adjacent to the exterior of the substantially cylindrical walled core inside the base and such that a distal edge of each of the at least one fin assembly of each of the plurality of heat sink segments is substantially exposed outside the base.
