An in-grade light fixture is provided with a corrugated housing design. The corrugated housing design enhances structural integrity and the flow of air within the light fixture to facilitate cooling. The light fixture includes an annular door with slots aligned with the corrugations to facilitate the influx of cool air into the housing and the exhaust of hot air from the housing. The light fixture includes a hot-aiming system that allows a tilt optic to be rotated via magnetic force within the light fixture using an external instrument, such as magnetic wand. The beam direction can be rotated using this hot-aiming system without opening the light fixture.

In-ground lighting with external optics aiming system

A recessed light includes an enclosure with a cavity, an opening into the cavity and a mounting surface about the periphery of the opening. An intermediate light assembly including a peripheral frame and a lamp is mounted on the mounting surface of the enclosure. The peripheral frame includes a main frame and extension rings which can be stacked to extend the lamp away from the cavity. The lamp has an array of light emitting diodes on a substrate which is affixed to and thermally integral with a pivotally mounted reflector mounted to the peripheral frame. The reflector provides cooling fins for the array of light emitting diodes. A lens associated with a lens frame is attached to the intermediate lamp assembly.

A knuckle assembly for mounting an electrical device includes a rotatable knuckle mount, an articulated knuckle and an electrical device mount. Two knuckle elements forming the articulated knuckle each include an open cavity, which together form a closed cavity. One of the knuckle elements is pivotally attached to the rotatable knuckle mount and the other includes the electrical device mount. A grommet is positioned in the closed cavity; and a fastener engages the knuckle elements and extends through the grommet. The grommet includes spherical or spheroidal segments complementary to the inner surfaces of the closed cavity and in interfering fit when assembled. The grommet is in non-rotational engagement with one of the knuckle elements. Wires extend through the grommet adjacent a central through hole. A fastener extending through the central through hole draws the knuckle elements together to fix the grommet and seal the assembly.

Mounting knuckle

A lighting system has a sealable housing with a lamp cavity, a junction box and a partition wall there between with the junction box being laterally from beneath a lens opening. The system further includes a closure to close an access port in the partition wall which includes a conical wall with a circular plate truncating the wall. The plate extends across the bottom of the housing and a vertically extending sealing flange receives the closure. A ballast assembly is also located from beneath the lens opening. A formed seal is positioned about a lens which extends inwardly to capture optic components beneath the lens. A locking ring is restrained from compressing against the mounting flange of the lens. A lighting system employing an LED board array and LED power control includes a heat sink beneath the board array extending downwardly to a radiator for transfer of heat from the array downwardly to the lamp cavity for dissipation.

In-grade lighting system

A fountain lighting system including a light engine head containing an LED light engine and a control housing containing control gear electronics includes a fixture support providing thermal separation between the light engine head and the control housing. The fixture support includes a lid with a bar extending from the edge thereof. The lid closes the control housing while the bar mounts the light engine head. An anchoring mount is also on the bar. The lid includes receptacles for receiving power, control and light engine cables with wicking barriers separating the various components provided in the lid itself. Temperature sensors in the light engine head and in the control housing send data communication to the control gear electronics to limit power to avoid thermal loading. The control gear electronics modulates the power to prevent apparent cycling. A pool lighting system provides similar features in a niche. A gap open to the niche thermally separates the light engine head from the control housing.

Combined bollard and light fixture

A bollard includes a bollard post having a lamp which includes a louver stack. The louver stack includes louvers spaced apart in the longitudinal direction of the bollard post. The bollard post is rectangular in cross section and the louver stack extends outwardly beyond the periphery of the bollard. There is a primary light source inwardly of the louver stack and a mechanism for providing light downwardly about the base end of the bollard post. One such mechanism includes an LED providing a light wash down the bollard post from beneath where that louver extends outwardly of the periphery of the bollard post. A second mechanism employs a top reflector above the primary light source to reflect light downwardly about the light source. Bottom reflector surfaces direct the light from the top reflector outwardly to louver reflectors located beneath the lowermost louver. Such reflectors can reflect light downwardly for light wash of the bollard post and an illumination about the base of the bollard post. The spacing between the lowermost louver and the periphery of the bollard post is exposed to the primary light source to create additional light downwardly to about the bollard post.

Bollard lamp

A bollard for mounting to a foundation includes a bollard post element having a cavity therein with a base plate integrally fixed about its periphery to the bollard post element at the cavity. The base plate includes anchor holes and threaded holes extending therethrough. Levelers having threaded shafts with pads on one end and drivers on the other engage the threaded holes. Threaded anchor shafts extendible through the anchor holes and fixable to the foundation for the bollard are drawn in tension by nuts on top of the based plate. This simultaneously places the levelers in compression. In installation, the highest point on the foundation beneath the periphery of the base plate is established and the levelers adjusted to extend the bollard vertically with the bollard extending from that highest point.

Bollard and method of mounting

A lamp assembly for outdoor purpose includes a housing, a lamp module, and a potted power module. A support ring is positioned within the housing so as to connect the housing to the lamp module. An additional tilt ring may be connected therewith to provide an additional degree of movement. The support ring and, if included, the associated tilt ring has the ability to key the lamp module to the housing. This makes it possible to relamp or perform maintenance on the lamp without affecting the aim or distribution of the light. In addition, the lamp assembly preferably includes at least one flue plate disposed between the lamp module and the housing to form at least one flue, the at least one flue advantageously creates and maintains convective cooling within the housing of the lamp assembly during operation.
