A system of networked lighting devices includes a central controller and a group of lighting devices. Each lighting device may include a fixture controller, one or more lighting modules, and a communication interface. The central controller receives data packets and send them to the lighting devices via a ring topology. The lighting devices may be connected to each other via the ring topology, or a set of routers may be connected in the ring topology, with each router controlling one or more connected lighting devices. The central controller and/or the fixture controllers may each translate data packets from one protocol to a different protocol. The different protocol may be a protocol that is compatible with the local system of networked devices, and/or a protocol that is compatible with the lighting device(s) that will use the data packets to actuate according to a command from the central controller.

A light assembly contains a housing. One or more LED light units are contained within the housing, wherein each of the LED light units may contain only one corresponding conductive end cap. A pair of conductors extending from each of the corresponding conductive end caps are mated with a corresponding socket contained within a DC power supply module contained within the housing.

A lighting apparatus is provided. The lighting apparatus includes a first light source module and a second light source module surrounding the first light source module. A half beam angle of the first light source module is smaller than a half beam angle of the second light source module. A correlated color temperature of light from the first light source module is higher than a correlated color temperature of light from the second light source module.

A lighting apparatus includes a first light source, a second light source, a first light guide plate, a second light guide plate and a driver. The first light source emits a first light. The second light source emits a second light. The first light guide plate receives the first light from a first lateral wall and guides the first light to escape via a first surface of the first light guide plate. The second light guide plate receives the second light and guides the second light to escape via a second surface of the second light guide plate. The second surface has an image pattern. The image pattern is rendered by placing multiple first light escaping dots on the second surface. The multiple first light escaping dots are divided into multiple sets for rendering multiple visual objects by arranging area intensities of the first light escaping dots.

In accordance with certain embodiments, systems of lighting components feature multiple illumination panels each having a backing support and, secured thereto, multiple illumination elements. The illumination elements have shapes defined by arrangements of illumination unit cells may be assembled to illuminate an arbitrary two-dimensional area.

A solid-state lamp includes a first plurality of solid-state emitters that emit light at visible wavelengths and a second plurality of solid-state emitters that emit light at a safe ultraviolet wavelength, wherein the second plurality of solid-state emitters emit light at least when the first plurality of solid-state emitters emit light.

A motor vehicle includes headlamps having a plurality of LED light sources, one or more processors, and a memory storing instructions. One or more processors executing the instructions are enabled to receive first data, including at least map data, indicating a road curvature upcoming along a road on which the motor vehicle is traveling. The processors are also enabled to determine a light change, the change adapting a light pattern of the headlamps in at least one of color, intensity or spatial distribution to increase light in a direction of the road curvature ahead of the motor vehicle and shaping light based at least in part on the road curvature. The processors are further enabled to control at least a first plurality of the LED light sources to provide light based at least in part on the determined light change and prior to the motor vehicle reaching the road curvature.

A lighting device is presented for highlighting a first product over a second product placed in a first and a second section respectively of a store fixture, display or shelf to draw a shopper's attention to the first product, the lighting device comprising: a first and a segment, adjacent to each other, arranged for providing a first light output for illuminating the first product and a second light output for illuminating the second product respectively, a controller arranged for changing an operational mode of the lighting device from a normal lighting mode to a highlighting mode based on a signal indicating presence of a field; wherein in both the normal lighting mode and the highlighting mode, the first segment and the second segment provide illumination, and wherein in the highlighting mode, the first segment highlights the first product over the second product.

A modular lighting assembly uses LED banks as the light sources. The assembly allows the power supply and LED banks to be independently replaced. The assembly uses a power supply that is separated from the LED banks and electrically connected to the LED banks with a plug connector that may be unplugged and plugged back in to allow the power supply or LED bank to be independently and readily replaced. The assembly provides for easy replacement of the different components of the assembly. One feature that makes the components easier to replace is that the light modules and/or the power supply may be carried by the housing that is removable from the base mount that is secured to a mounting structure such as a wall or ceiling.

A ceiling element including a base adapted to be mounted in a ceiling of a room, thereby defining a room space under the base and a ceiling space above the base, is provided. The ceiling element includes a battery container adapted to receive a battery and arranged at the base such that it is located in the ceiling space when the ceiling element is mounted in the ceiling. The ceiling element further includes a conduit arranged to convey air between the room space and the ceiling space and/or the battery space when a temperature of the room space is different from a temperature of the ceiling space and/or a temperature of the battery container. A method of thermal management of a battery received in a battery container located in a ceiling space is also provided.
