In addition, the light body may be moved with respect to the adjustment bracket to provide more flexible light effect.

An integrated-lighting-module may have a driver cap, a heat sink module, a LED light chip, an optical reflector, and a holder/trim. The driver cap may be configured to hold a driver within the driver cap to power the LED light chip. The driver cap may attach to a top of the heat sink module. The heat sink module may be finned at various locations. The holder may attach to the heat sink module with the optical reflector and the LED light chip disposed between elements of the holder and elements of the heat sink module. Trim, such as MR16 sized trim, a lamp, and/or a lens holder, may attach to bottom flanges of the holder. The integrated-lighting-module may be adjusted without interfering with the trim. The holder may be trim in some embodiments.

The present disclosure is directed to wallpacks containing at least one light source, such as a light-emitting diode (LED). The wallpack light fixtures disclosed herein generally contain a housing, at least one light source, a power supply, and a plurality of heat sink fins.

A light device including a housing having at least one wall that defines an internal cavity. A heat sink is attached to the housing. The heat sink includes a body, a plurality of mat fins disposed about a periphery of a body, and a plurality of pin fins disposed in staggered rows on a central portion of a face of the body. The plurality of mat fins direct air in a predetermined direction to the central portion and the plurality of pin fins define a plurality of tortuous air paths along the central portion.

A light emitting device includes a housing; a light source unit; and a cooling unit provided in the housing to discharge heat to an outside of the housing by means of a gas, the heat being generated by the light source unit. The cooling unit includes an introduction portion, a heat exchange portion, and a circulation portion that guides the gas from the introduction portion to the heat exchange portion. The circulation portion includes a first flow path receiving the gas from the introduction portion, and a second flow path receiving the gas from the first flow path, and being connected to the heat exchange portion. The first flow path includes a portion having a flow path area larger than a flow path area of the introduction portion.

A luminaire has a first housing portion and a second housing portion formed of a polymeric material. A hinge pivotably connects the first housing portion to the second housing portion and includes a pintle formed as one-piece with one of the first and second housing portions and a knuckle formed as one-piece with the other one of the first and second housing portions. A sealing structure seals a compartment formed between the first housing portion and the second housing portion. The sealing structure includes a channel supported by one of the first and second housing portions and a frame supported in the channel. The frame supports a deformable gasket. A sealing member extends from the other one of the first and second housing portions where the sealing member extends into the channel and engages the gasket. A locking feature secures the first housing portion to the second housing portion.

The invention relates to a heat sink (1, 100) for a light source of a motor vehicle light module, wherein: the heat sink (1, 100) comprises a main body (2) and cooling plates (3, 300) which can be arranged on the main body (2); when the cooling plates (3, 300) are connected to the main body (2), the cooling plates (3, 300) are in heat-conducting contact with the main body (2), each cooling plate (3, 300) having a base side (31, 310); the main body (2) has fastening elements (21) on a surface (22), the surface (22) facing the base sides (31, 310) of the cooling plates (3, 300); counter elements (32) mating with the fastening elements (21) are arranged on each base side (31, 310), the fastening elements (21) being designed to engage in the counter elements (32); the fastening elements (21) are arranged in a grid (23); the counter elements (32) are arranged on the respective base sides (31, 310) at regular distances (d1) from one another, and the grid (23) has a grid spacing (d2), the grid spacing (d2) being greater than the distance (d1) between the counter elements (32).

An assimilation lamp device (101; 800) for stimulating plant and crop growth comprises: a central lamp unit (10), comprising a body (14) and one or more LEDs (12) mounted to the bottom surface of the body, wherein the body acts as a heat sink for the heat generated by the LEDs. The device further comprises air stream generating means (42) for generating a downward air stream (43; 341), and heat transfer and exchange means for transferring heat from the body to the air stream, so that heat from the LEDs is used to increase the temperature of said downward air stream and is eventually used to warm the environment of the plants. A device controller (850) has a set point input (859) and generates control signals for the LEDs and the air stream generating means in conformity with an input signal received at its set point input.

A plant growing lamp includes a lighting unit and a hanging unit. The lighting unit includes a control box and a sliding part, and the hanging unit includes connection lines and a rope ratchets. Cables such as the rope ratchets and the connection lines can be roughly pulled straightly and fully by weight of the lighting unit. The rope ratchets can be pulled to adjust a distance between the lighting unit and the hanger, so as to change an interval between a lamp of the lighting unit and the plants under the lighting unit, thereby appropriately adjusting light intensity for plant growth to prevent from burning the plants.

A thermally conductive polymer luminaire includes a polymer housing including at least one thermally conductive filler to configure the polymer housing as a thermally conductive polymer housing. The housing includes an inner surface, an outer surface, and a thickness extending between the inner surface and outer surface. The thickness varies along a length of the housing. An electrical component is mounted to the inner surface of the housing opposite a location of the housing having a reduced thickness to facilitate thermal energy release from the housing. A light source is mounted to the housing and electrically connected to the electrical component for emitting light from the housing.
