Lighting assembly
A lighting assembly including a shell, wherein the shell includes an inner wall defining an inner lumen, an outer wall encircling the inner wall, a set of radial fins connecting the inner and outer walls, the set of fins cooperatively defining a set of cooling channels between adjacent fins, the inner wall, and the outer wall; an insert removably mounted within the inner lumen, the insert defining a power storage lumen; a power storage unit arranged within the power storage lumen; a circuit board coupled to the power storage unit, the circuit board comprising a processor and communication module; a lighting module electrically connected to the circuit board, wherein the lighting module includes a substrate and a set of light emitting elements mounted to a first broad face of the substrate.
Street light with neck cuff
In one aspect, a light fixture assembly configured for exterior lighting includes a light fixture. The light fixture includes an LED light source configured for exterior lighting, a driver configured to power the light source and a first electrical connector coupled to the driver. The light fixture also includes a housing to house the LED light source and the driver, where the housing includes an elongated extension on which the first electrical connector resides. The light fixture assembly also includes a neck cuff that fits securely to a light pole. The neck cuff includes a second electrical connector inside that is connected to a power source in the light pole. The extension of the light fixture is configured to be inserted into the neck cuff such that the first electrical connector of the light fixture removably connects to the second electrical connector of the neck cuff.
Connectors for Linear Lighting
A connector for a strip of linear lighting includes an outer shell or block and an adapter configured to be removably inserted into a cavity of the outer shell. The adapter may be a printed circuit board (PCB) adapted to mount wires on one side or edge. On the opposite side or edge, a series of contact pins are formed on the underside of the adapter. The outer shell includes a pressure-applying mechanism, like screws that insert through its thickness and are secured in a bar with threaded holes. The adapter is positioned such that the screws bear on and supply pressure to the contact pins. A strip of linear lighting is inserted into a slot beneath the adapter such that the contact pins of the adapter coincide with the solder pads or other electrical contacts of the strip of linear lighting.
Compressive heat sink
A heat-sink assembly is configured with two parts to grip a light-emitting element and produce a transverse force urging a surface of the light-emitting element toward a surface of the heat-sink assembly, which conducts heat away from the light-emitting element. Fastening mechanisms and a fulcrum inter-connect the heat-sink parts and produce the force that grips the light-emitting element. A configuration of the heat-sink parts creates a semi-enclosed space accessible through a gap. A configuration of elastomeric gaskets within the semi-enclosed space protects a portion of the space from intrusion of liquids or other environmental influences. Configuration of the heat-sink parts to form a recess in the heat-sink assembly provides protection of the light-emitting element from mechanical damage, and the recess may contain transparent materials that further protect the light-emitting element from detrimental environmental influences.
LIGHTING DEVICE WITH LIGHT-EMITTING FILAMENTS
There is presented a lighting device comprising: several light-emitting filaments (15, 15′) with solid-state light sources and a circuit board (10) with first and second electrically conductive tracks (13, 14) following first and second paths, respectively. Each light-emitting filament (15, 15′) comprises a first electrical contact (19, 19′) electrically connected to the first track (13) at a first point on the first path, and a second electrical contact (20, 20′) electrically connected to the second track (14) at a second point on the second path. The first and second points associated with each light-emitting filament (15, 15′) are arranged on an axis (A) which is non-perpendicular to a tangent (T.sub.1) to the first path at the first point and to a tangent (T.sub.2) to the second path at the second point. The lighting device may be adapted to emit light from what appears to be a surface according to an observer.
LIGHT FIXTURE CONNECTION SYSTEM AND OPTIC HOLDER
A connection assembly includes an electrical cord providing electrical communication between a first light fixture and a second light fixture, and a cover removably coupled to the first light fixture and the second light fixture. The electrical cord includes a first electrical connector coupled to the first light fixture, and a second electrical connector coupled to the second light fixture. The cover extends over the electrical cord, and includes a first end adjacent the first light fixture, a second end adjacent the second light fixture, and a surface extending between the first end and the second end. The cover provides a continuous surface between the first light fixture and the second light fixture.
Lighting device for a motor vehicle
Lighting device for a motor vehicle including a light source and/or an optical part. A substrate including electrical tracks, the light source and/or optical part being fastened to the substrate, and a part forming an electrical ground for the electrical tracks. The substrate includes a cut-out forming a tab, electrical tracks of the substrate extending onto the tab, at least one of the tracks on the tab making electrical contact with the ground-forming part.
DUO LED LIGHT FIXTURE WITH A DOWNLIGHT SOURCE AND AN OPTIONALLY OPERABLE UPPER LIGHT SOURCE
A dual LED light fixture is comprised by a lower LED light source housing and an upper LED light source housing. A lower LED light source is mounted in the lower light source housing to generate downlight. An upper LED light source is mounted in the upper LED light source housing and remote from an outer circumferential light transmitting outer side area of the upper light source housing and from which is emitted side light illumination. An LED power supply and light control circuit mounted in the LED light fixture and adapted for connection to a power source. The LED light power supply and control circuit has a dimming circuit and a lower and upper driver current supply circuit. A switch is operative to connect driver current to the upper LED light source when actuated to an “on” position and to disconnect driver current to the upper LED light source when in a normal “off” position. The switch is operative for engagement to its “on” position when desirable to provide drive current to the upper light source and illumination from both the lower and upper LED light sources of the LED light fixture. Various embodiments of the LED light fixture is described.
