Electronics housing assembly with improved heat dissipation

A light fixture comprising:

• a. a lighting subassembly comprising:
• i. a chassis body having an upper side, a lower side, a chassis outer perimeter edge, and a central aperture extending from the lower side to the upper side such that air may pass through the central aperture upwardly from the lower side to the upper side of the chassis body, wherein an aperture edge defines the central aperture and a central aperture area;
• and
• ii. at least one LED module mounted on the lower side of the chassis body;
• and
• b. an electronics housing having an upper side and a lower side and comprising:
• i. a central driver compartment having a compartment perimeter and comprising at least one base wall, a first sidewall, and a second sidewall, wherein the first sidewall and the second sidewall extend upwardly from the base wall;
• and
• ii. a plurality of perimeter heat sink fins extending outwardly from the central driver compartment, wherein adjacent perimeter heat sink fins define air passageways between the upper side and the lower side of the electronics housing and wherein the air passageways are adapted to receive air passing upwardly through the central aperture of the chassis body;
• iii. a first driver positioned within the central driver compartment such that a first surface of the first driver is in contact with the at least one base wall and a second surface of the first driver is in contact with the first sidewall;
• iv. a second driver positioned within the central driver compartment and physically isolated from the first driver, wherein a first surface of the second driver is in contact with the at least one base wall and a second surface of the second driver is in contact with the second sidewall;
• and
• V. a cover adapted to engage the electronics housing to enclose the central driver compartment.

An electronics housing assembly comprising:

• a. an electronics housing having an upper side and a lower side and comprising:
• i. a central driver compartment having a compartment perimeter and comprising at least one base wall, a first sidewall, a second sidewall adjacent the first sidewall, and a third sidewall adjacent the first sidewall and the second sidewall, wherein the first sidewall, the second sidewall, and the third sidewall extend upwardly from the at least one base wall and form a triangular shape;
• ii. a plurality of perimeter heat sink fins extending outwardly from the central driver compartment, wherein adjacent perimeter heat sink fins define air passageways that extend between the upper side and the lower side of the electronics housing;
• and
• iii. at least one connecting wall spaced outwardly a distance from the central driver compartment and that connects at least some adjacent perimeter heat sink fins such that at least some of the air passageways are bounded by the adjacent perimeter heat sink fins, the connecting wall, and the central driver compartment;
• b. a first driver positioned within the central driver compartment such that a first surface of the first driver is in contact with the at least one base wall and a second surface of the first driver is in contact with the first sidewall;
• c. a second driver positioned within the central driver compartment and physically isolated from the first driver, wherein a first surface of the second driver is in contact with the at least one base wall and a second surface of the second driver is in contact with the second sidewall;
• and
• d. a cover adapted to engage the electronics housing to enclose the central driver compartment.
