A method is disclosed of modifying a lighting apparatus including a housing. The method involves detachably attaching at least one speaker to the housing when the at least one speaker is in the housing. At least one light source is detachably attachable to the housing independently from attachment of the at least one speaker to the housing. Lighting apparatuses are also disclosed.

An underwater light having a replaceable light-emitting diode (LED) module and cord assembly is provided. The underwater light includes a lens, a bezel, a screw, a cable attachment assembly, a mounting flange, a rear housing, a fastening assembly, an internal lens, a printed circuit board (PCB) including light-emitting diodes (LEDs) mounted thereon, a heat sink, and an electronics assembly. The assembly of the underwater light provides for the dissipation of heat away from the PCB thereby cooling the LEDs and electronic components mounted thereon. The electrically non-conductive nature of the exterior components of the underwater light permit the underwater light to be installed in any location in a pool or spa. Since the exterior of the underwater light is electrically non-conductive, no specific bonding or grounding of the underwater light is necessary.

An embodiment of an LED luminaire assembly is provided. The LED luminaire assembly includes an LED assembly configured to emit light and a lens coupled to the LED assembly and forming a concavity facing the LED assembly. The lens includes a side wall forming an opening sized to receive at least part of the LED assembly and a bottom opposite the opening and coupled to the side wall. The side wall further includes one or more prisms positioned proximate the bottom and configured to direct the light emitted from the LED assembly away from the bottom.

The present invention generally relates to lighting systems, in particular, to adjustable down lights using an arc assembly and turntable component system providing a compact adjustable insulation contact (IC) light housing having the ability to adjust the direction of the light source, a field-swappable modular component system, and a modular trim system providing, in some scenarios, lighting flexibility and glare-free viewing angles.

Reduced glare light fixtures are provided. In one example implementation, a reduced glare light fixture includes a light emitting diode (LED) system. The LED system includes at least one LED module having one or more LED devices. The reduced glare light fixture further includes a bezel physically coupled to the LED system engine. The bezel has one or more glare reduction openings. At least one of the one or more glare reduction openings is configured to be approximately coaxial with one LED of the one or more LED devices.

A light fixture includes a housing, and a lighting module. The housing defines first and second portions. The second portion defines a window. The lighting module is at least partially disposed in the second portion. The lighting module includes a submount, a plurality of light emitting diodes, a lens cover, and an encapsulating material. The plurality of light emitting diodes is coupled with the submount and is configured to project light through the window. The lens cover includes an exterior surface and overlies the plurality of light emitting diodes and the submount such that the lens cover and the submount define an interior therebetween. The encapsulating material substantially fills the interior.

Embodiments disclosed herein describe systems and methods for heat sinks within light fixtures. In embodiments, the heat sink may be a passive system that creates a cross-flow thermal management system to dissipate large amounts of heat in a slim light fixture. Embodiments may utilize a series of wings assembled in a linear design that are positioned perpendicular to the length of the light fixture to preserve the cross-flow heat sink.

The present invention discloses a modular lamp, including several modular units and lamp connectors, where the modular unit is a single lamp, and the lamp connector is configured to connect to the modular unit; and a male connector terminal on either side of each lamp connector is electrically plug-connected to a female connector terminal of one modular unit. In the present invention, female connector terminals connected to a power cable and a control cable are disposed on the modular unit, matched male connector terminals are disposed on the lamp connector, and the lamp connector is directly plug-connected to multiple modular units, so that the multiple modular units can be simultaneously physically and electrically connected to obtain the modular lamp. In this way, diversified lighting requirements can be met by adding different installation accessories to the modules. In addition, assembly operations can be completed by simply performing plugging and unplugging operations, without needing a professional to perform cable-connection and cable-routing between the modular units. Special scenario requirements such as good lighting effects and high ambient temperatures can be met by adjusting module power.

An adjustable, modular flood light fixture is provided herein which includes a plurality of light modules, each including an enclosure and a luminaire configured to generate light, the luminaire being pivotably mounted to the enclosure. The light modules are serially connected with the luminaires of the light modules being each independently, pivotably adjustable. Advantageously, with the subject invention, the size of an illuminated area may be controlled by the number of light modules being used, with pivoting adjustment allowing further control over how light from each of the light modules is directed.

A presence or an absence of an occupant is detected, and an occupancy sensor signal is generated representative of an active state in which the presence of the occupant is detected, and an inactive state in which the absence of the occupant is detected. An ambient light sensor detects the ambient light level and generates an ambient light sensor signal representative of the ambient light level. Dimmable illumination is generated at a first dimming level, based on the ambient light level, corresponding to the active state and a second dimming level corresponding to the inactive state. A transition delay time between an onset of the inactive state and a transition between the first dimming level and the second dimming level may be controlled. The first dimming level, the second dimming level, and/or the transition delay time may be variably set or controlled locally or via a remote device.
