A lighting apparatus includes a circuit board and light emitting diodes (LEDs) attached to the circuit board. The LEDs are arranged in an array of row and columns and are attached to the circuit board are arranged in a single plane. A support substrate supports the circuit board. Optical elements are configured to redirect light from the plurality of LEDs. Each optical element is substantially the same as all other optical elements. Each LED is associated with a single optical element and each optical element is associated with a single LED. The lighting apparatus is configured to direct light away from the circuit board so that the light is directed so as to illuminate a substantially rectangular area that is off-center relative to the light assembly. The substantially rectangular area has an edge that is at least 14 feet in length.

An illustrative light fixture provides an emitter housing and a driver housing in a single fixture with an airflow channel defined between the emitter and driver housings. The airflow channel minimizes thermal conduction between the emitter and driver housings, and maximizes thermal convective cooling for at least one of the emitter housing and driver housing. The emitter housing includes vertical fins extending into the airflow chamber. The left and right sides of the emitter and driver housings define top and bottom edges that are respectively coplanar with the top and bottom edges of the vertical fins.

Apparatus and associated methods relate to an LED device having thermally compartmentalized enclosures. In an illustrative example, a lighting device may include an LED module and a power circuit. The power circuit, for example, may include a heat generating component (HGC) (e.g., a power transistor) and a thermally sensitive component (TSC) (e.g., a capacitor). For example, the lighting device may include a first enclosure including the HGC, and a second enclosure including the TSC. In operation, the first enclosure may be higher than the second enclosure. In some implementations, the second enclosure may be thermally isolated from the first enclosure, and physically external to the first enclosure and the LED module. For example, the second enclosure may be exposed to an ambient environment. Various embodiments may advantageously maintain the temperature of the second enclosure isolated from, and lower than, the temperature of the first enclosure.
