Street lighting device including traffic sensing and communication with observers and associated methods
A thoroughfare lighting device includes a housing to be attached to a thoroughfare surface, and including sidewalls that taper. A plurality of light-emitting diodes (LEDs) selectively illuminate individual lanes, including a first set of LEDs to emit a generally white light, and a second set of LEDs to emit colored light that is observable by an observer. A driver circuit operates the second set of LEDs to emit colored light illuminating a single lane indicating a condition of the individual lane. Optics may be carried by the housing and positioned in optical communication with at least a portion of the plurality of LEDs. A traffic sensor communicatively coupled to the driver circuit and configured to sense a traffic pattern and generate information regarding traffic on the associated thoroughfare. The driver circuit is configured to operate the plurality of LEDs responsive to the information generated by the traffic sensor.
Pixelated Water Display and Design Tools Therefor
A water display including a number of pixels or manifolds that may include water nozzles to emit streams of water and/or other utilities such as lighting is described. The water streams may be pixelated so as to provide a high resolution waveform or other choreography. The choreography transitions between waveforms to provide the appearance of a cascading or undulating wave. A tool to design the water display and simulate its appearance is also described.
Luminaires
An LED luminaire (10) comprising: a main body portion (12) adapted, in use, to house an LED light panel (24); a mount (14) for securing, in use, the luminaire (10) to a surface; a driver unit (62); and a hinge (16, 42, 44) adapted to hingedly connect the main body portion (12) to the mount (14), wherein the hinge (16, 42, 44) comprises a, hollow interior volume for accommodating the driver unit (62), and wherein the driver unit (62) comprises a water-resistant housing.
Adjustable light fixture and lighting system
An adjustable light fixture and lighting system are selectively adjustable in the field and provide even light distribution across a space. A housing is selectively adjustable to a selected housing length and is mountable to the surface. A tray mountable to the housing includes plates which are selectively adjustable relative to one another to a selected tray length. Each plate includes a plurality of electroluminescent light sources providing uniformly luminous light across the light fixture. Overlap of plates varies the tray length and blocks light from light sources on one plate by the opposite plate. Evenly distributed light is therefore provided with no bright or dark spots. A lighting system of a plurality of light fixtures electrically connected to one another includes at least one adjustable light fixture, and preferably at least one stationary light fixture of fixed length. Methods of installation are also disclosed.
PLANAR LIGHT SOURCE AND ILLUMINATION APPARATUS
The present invention provides a planar light source and an illumination apparatus which have higher design property than that of conventional ones. The planar light source includes: a planar light emitting panel which has a light emitting surface; and a decorative member which covers the light emitting surface of the planar light emitting panel. A light emitting region which emits light when the planar light source is turned on and a non-light-emitting frame region which surrounds the light emitting region are provided on the light emitting surface. The decorative member has a pattern forming section. The pattern forming section includes a frame shielding section which covers entirety of the frame region in the front view, and a light-emission shielding section which extends from the frame shielding section so as to divide the light emitting region into a plurality of regions.
ADJUSTABLE LIGHT FIXTURE AND LIGHTING SYSTEM
An adjustable light fixture and lighting system are selectively adjustable in the field and provide even light distribution across a space. A housing is selectively adjustable to a selected housing length and is mountable to the surface. A tray mountable to the housing includes plates which are selectively adjustable relative to one another to a selected tray length. Each plate includes a plurality of electroluminescent light sources providing uniformly luminous light across the light fixture. Overlap of plates varies the tray length and blocks light from light sources on one plate by the opposite plate. Evenly distributed light is therefore provided with no bright or dark spots. A lighting system of a plurality of light fixtures electrically connected to one another includes at least one adjustable light fixture, and preferably at least one stationary light fixture of fixed length. Methods of installation are also disclosed.
Multi-use auxiliary light
Disclosed is a multipurpose assistance lamp in which a lighting unit includes a transparent film and a casing plate, which have a curved surface, respectively, and are disposed on a front surface and a back surface of an OLED lighting sheet having a curved surface, a rotary body is coupled to one end portion of the lighting unit so as to support the lighting unit, and a circuit part and a battery for operating the OLED lighting sheet are provided in a base that is hingedly coupled to the rotary body, thereby reducing or minimizing a thickness by adopting an OLED as a light source, and providing light having improved brightness.
Illuminating safety and notification device
A safety device comprises a light source, a power source coupled to the light source, a controller coupled to the light source and the power source to control operation of the lighting device, and a connection port that transmits and receives power up and control signals. In some embodiments, the connection port transmits and receives a wired signal. In further embodiments, the connection port transmits and receives a wireless signal. In some embodiments, the connection port receives a signal from an external source. In some of these embodiments, the external source is a remote control. In further embodiments, the external source is a program located on a computing device. In still further embodiments, the external source is one or more additional connection port of one or more additional safety devices. In some embodiments, the signal is a signal to power the light source.
Electrically conductive carriageway marking
An electrically conductive carriageway marking includes a carrier strip, electrically conductive wires extending along the carrier strip, an electrically insulating covering layer covering the wires, a power feed formed by an interface connecting the wires to a supply line, and interfaces arranged spaced apart from each other along the carriageway marking and having electrical contact areas. The contact areas include contact elements protruding laterally from the carriageway marking, and the supply line is connectable to a first contact area of the wires and a second contact area of the wires by electrical contacts that can be tapped off. In the region of the contact areas the covering layer is formed by a detachable adhesive protective strip, and the protective strip is connected via predetermined break points or perforations to adjoining sections of the covering layer, and the wires are exposed by detaching the protective strip.
Lighting panel adapted for improved uniformity of light output
The invention provides a lighting panel, for use for example within a modular surface system, comprising one or more strips of solid state lighting elements associated with a reflector structure. The lighting panel is adapted for improved uniformity of light intensity across the width of its output area. Lighting elements comprise two or more subsets, each subset adapted to collectively generate a different light intensity profile across the width of the panel output window. The subsets are selectively adapted to generate profiles which, when blended, mutually offset one another's deviations from some common mean intensity across the width of the output window, thereby generating a combined intensity profile of improved uniformity. Embodiments include arrangements in which subsets of lighting elements are adapted to have differing actual or virtual optical path lengths to the reflector surface. Also provided are embodiments further comprising an acoustically absorbing back surface, for providing an acoustic dampening function.
