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.

One embodiment of exhaust component (30) contains a shield (40). The shield being opaque allows indefinite designs to be cut out. These designs are illuminated by illumination assembly (36), which enhances cutouts (44), thereby allowing them to remain visible under all conditions. Another embodiment of the exhaust component without the shield contains illumination modules (58). These modules illuminate the exhaust component's mouth (32) through base (22) or outer wall (34), and this allows the shape of the exhaust component to be the design feature. The illumination of the mouth both enhances the shape and allows it to remain visible under all conditions. These embodiments can occur alone or together for both maximal design enhancement and additional visibility of the vehicle thereby increasing safety.

An illumination apparatus includes a case, a plurality of oscillators configured to generate electromagnetic waves, and housed in the case and arranged two-dimensionally, a window unit configured to emit therefrom the electromagnetic waves, and disposed on a first side of the case, a plurality of inflow holes configured to allow fluid to flow into the case, and disposed at positions at which the electromagnetic waves from the window unit propagate, and a discharging unit configured to discharge the fluid, which has flowed into the case, out of the case, and disposed on a second side of the case, which is an opposite side to the first side. When the oscillator is viewed from the window unit, a part of the oscillator is located on an inner side of the inflow hole, and the fluid which has flowed into the case through the inflow hole reaches the oscillator.

Sensor housings, modules, and luminaires comprising the same are provided. The sensor housings and modules set forth herein have improved heat sinking abilities for dissipating heat from a sensor while simultaneously facilitating thermal isolation of the sensor. Briefly, a sensor housing described herein comprises a cavity for housing a sensor and a heat sink. The heat sink is configured to dissipate heat from the sensor housing and thermally isolate the sensor housing from other heat generating components, such as other portions of a luminaire.
