A recessed light fixture includes an LED module, which includes a single LED package that is configured to generate all light emitted by the recessed light fixture. For example, the LED package can include multiple LEDs mounted to a common substrate. The LED package can be coupled to a heat sink for dissipating heat from the LEDs. The heat sink can include a core member from which fins extend. Each fin can include one or more straight and/or curved portions. A reflector housing may be coupled to the heat sink and configured to receive a reflector. The reflector can have any geometry, such as a bell-shaped geometry including two radii of curvature that join together at an inflection point. An optic coupler can be coupled to the reflector housing and configured to cover electrical connections at the substrate and to guide light emitted by the LED package.

A light including a housing having an upper portion, a lower portion, and a central axis. The lower portion defines a battery port. The upper portion acts as a lens. The light further includes a heat sink extending upward from the lower portion of the housing and including a body defining a central aperture. A plurality of light support surfaces are arranged around a perimeter of the body and a top support member is coupled to and oriented perpendicularly relative to the plurality of light support surfaces. The light further includes a first plurality of LEDs coupled to the plurality of light support surfaces and a second plurality of LEDs supported on the top support member. The light further includes a first battery pack and a second battery pack, both of which are electrically connected to the first and second pluralities of LEDs when received in the battery port.

A heat sink (140) for cooling an electronic component of a vehicle headlamp, which has a cooling structure with an outer contour, which, as viewed along an imagined sectional plane, follows a contour curve, which can be described in at least one section by means of a contour function, wherein a fundamental course is formed from a first superposition of a base function and a fundamental function, and the contour function is formed from a second superposition of the fundamental course and a superposition function, wherein the first superposition takes place in that the functional course of the base function forms an axis of a curved coordinate system of the fundamental function, and the second superposition takes place in that the functional course of the fundamental function forms an axis of a curved coordinate system of the superposition function, wherein the base function has a straight, circular or arc-like course, and the fundamental function has a straight or wave-like course, and the superposition function has a wave-like course.
