A light emitting device comprises a light emitting element having a light emission peak wavelength in a range of 400 nm or more and 490 nm or less and a first fluorescent material having a light emission peak wavelength in a range of 570 nm or more and 680 nm or less, and emits light having a correlated color temperature being 1,950 K or less, an average color rendering index Ra being 51 or more, a full width at half maximum of a light emission peak having a maximum light emission intensity in a light emission spectrum of the light emitting device being 110 nm or less, and a first glare index Ls1/L that is a ratio of a first effective radiance Ls1 to a luminance L being 0.493 or less, wherein Ls1 and L are as defined in the disclosure.

The present invention relates to a novel crosswalk light device. The device is designed to ensure that a crosswalk is highly visible during nighttime and other lowlight hours of the day to prevent accidents. The device comprises an LED floodlight mounted on top of a pedestrian crosswalk signal. The light illuminates the crosswalk area during the walking phase of the crosswalk. The light is wired through a series of relays and a capacitor to hold steady voltage. Accordingly, the device maintains an optimal level of safety for both pedestrians and motorists.

Apparatus and associated methods relate to an energy efficient and pollution reducing post top lamp. In an illustrative example, a replaceable light unit (RLU) includes a LED package distributed about a first axis of the RLU. The LED package, for example, may emit a light being redirected by a first optical element to generate a first optical distribution along a first optical axis in a first direction, the first optical axis being substantially parallel to the first axis. The first optical distribution may be, for example, reflected by a second optical element such that at least a portion of the light in the first optical distribution may be reflected into a second optical distribution. For example, at least fifty percent of the light in the second optical distribution may be greater than fifty degrees from the first optical axis. Various embodiments may advantageously conserve energy and/or reduce light pollution.

A solar energy harvesting assembly having a unique attachment that can be arranged, mounted, moved and attached to new or existing structures. Solar rings are mounted on any vertical structure that may benefit from solar power using an aesthetically pleasing design that is resistant to wind load. The assembly does not require the need for pitch, azimuth or bearing measurements. The assembly is also capable of energy harvesting from reflected light below with the use of bifacial photovoltaic panels. The mounting design allows the solar energy harvest device to be installed on any vertical structure, including light poles, power poles, parking structures and other minimal load bearing structures. Further, the assembly can be attached to water towers, existing radio towers (guyed, monopole, stealth, self-supporting towers) all used to create vast amounts of unshaded vertical space for solar energy harvesting.

It is disclosed a lamp for public, industrial or commercial lighting, with radio control. The lamp comprises a casing provided with an opening, a protection screen and a printed circuit board housed entirely inside the casing. The board comprises a printed circuit board comprising a mounting surface on which are mounted at least one light beam source, a processing unit, a transceiver of wireless signals connected to the processing unit, an antenna connected to the transceiver and a power supply circuit.

The invention provides a light management information system for an outdoor lighting network system, having a plurality of outdoor light units each including at least one sensor type, where each of the light units communicates with at least one other light unit, at least one user input/output device in communication with at one or more of said outdoor light units, a central management system in communication with light units, said central management system sends control commands and/or information to one or more of said outdoor light units, in response to received outdoor light unit status/sensor information from one or more of said outdoor light units or received user information requests from said user input/output device, a resource server in communication with said central management system, wherein the central management system uses the light unit status/sensor information and resources from the resource server to provide information to the user input/output device and/or reconfigure one or more of the lights units.

A system for upgrading and retrofitting existing streetlights. The system enables conventional streetlights using sodium vapor, and other conventional lighting technologies, to be upgraded to more energy efficient and long-lasting LED lighting. At the same time, cellular and wireless communications can be added to the streetlight to provide additional bandwidth over that provided by conventional cell towers. The system can offload bandwidth in otherwise overloaded areas, such as densely populated urban areas. The system can include mini- or micro-cellular routers, GPS, Wi-Fi, Bluetooth®, and other micro cellular and wireless technologies. The system can include a light fixture styled to look like existing conventional light fixtures and can be retrofitted to existing streetlight poles and mounts with little, or no, modification to the pole and wiring.

A street equipment assembly including a base and a plurality of poles. The poles can accommodate external devices, and the base is for receiving internal devices. The street equipment assembly allows sufficient electronic equipment to be installed on limited areas of roads, thereby in line with the needs of electronic equipment for smart urban development. The street equipment assembly in the present invention includes a connection pipe for guiding and connecting lines of the external and internal devices to the base. The connection pipe is further extended upwards to have its opening reach above top of the base to form a chimney structure. The chimney structure can prevent any liquid at the top of the base from entering the base through the opening of the connection pipe and can dissipate heat out of the base.

In one aspect, an exterior lighting insect zapper includes a photosensor configured to sense an amount of light for turning on or off an exterior light and an insect zapper coupled to the photosensor. The exterior lighting insect zapper also includes a twist-lock plug compatible with a receptacle of an exterior light for a photosensor unit plug, such that the exterior lighting insect zapper can replace existing photosensors of exterior light fixtures.

A twist-lock connector system includes a first twist-lock connector including a first connector housing holding first twist-lock contacts at a first rotate-to-mate interface. The first twist-lock connector includes a first high speed electrical connector. The first high speed electrical connector is movable relative to the first connector housing between a home position and a rotated position. The first twist-lock connector includes a biasing member coupled to the first high speed electrical connector to bias the first high speed electrical connector to the home position. The twist-lock connector system includes a second twist-lock connector having a second connector housing holding second twist-lock contacts and a second high speed electrical connector at a mating interface.
