    摘要： 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.

    摘要： An illumination apparatus has a light source having a planar emission surface and a centroid, wherein the surface has a maximum distance L between opposite edges. A lens has an incident surface and an optical axis. In cross section along the optical axis, the incident surface, at a first incident point, is concave or flat to light emitted at a normal from the emissive surface. At a second incident point, the surface an instantaneous angle of curvature, relative to the emissive surface, with an absolute value of no more than 25 degrees to light emitted at an oblique angle greater than 75 degrees from the emissive surface normal. Considered in parallel to the optical axis, the second incident point is within a less than 0.2 L from the first plane. In an orthogonal direction to the optical axis, the second incident point lies within less than 2 L from the centroid.

    摘要： Apparatus and associated methods relate to development of a LED system with high thermal dissipation power relative to the system weight by the inclusion of open regions. The open regions reduce the weight of the optical system while improving airflow. Associated optics are described to efficiently and evenly distribute the light from an LED by tailoring the optical distribution. In addition, circuitry and methods are described to allow for the LED system to operate with existing power sources such as ballast or offline AC voltage sources or both.
