A bracket is pivotally attached to the linearly extending luminaire, the bracket having an axis of rotation around a horizontal axis, whereby the linearly extending luminaire is separately rotatable along a horizontal axis relative to the elevated structure. The bracket also has an axis of rotation around a vertical axis, whereby the linearly extending luminaire is separately rotatable along a vertical axis relative to the elevated structure.

An attachment device 10 for securing a lighting shade 20 to a lighting fixture 30, wherein the lighting shade 20 has an upper surface 22 for receiving thereon a plurality of magnet members 24, 26, and 28 that form the attachment device 10. The lighting fixture 30 has a connection housing 32 and an engaging surface 34 for engaging the attachment device 10 having magnet member 24, 26, and 28 on the upper surface 22 for retaining the removably connected lighting fixture 30 to the magnet members 24, 26, and 28 on the lighting shade.

According to aspects of the embodiments, an integrated light and heat arrangement of low profile light-emitting diode (LED) fixture to harness both the light and the heat generated by the LEDs is described. New system architectures and example form factors are provided for the development of new LED fixtures for integrative lighting and heating arrangement to increase their overall luminaire system efficiency. The integrative lighting and heating arrangement of the LED fixture in low profile design can minimize interference of harvesting the heat from LEDs with their light output. The heat which would otherwise be wasted from LEDs is harvested for the purpose of heating up some nearby body, such as a body of air, or a component, or a lens to accomplish some benefits, including, for example, reduction in overall energy uses for space heating, cooling, and lighting and associated cost, and melting snow and de-icing on outdoor LED fixtures for safety and security.

A modular approach is provided for sensing and responding to detected activity or an event in a region that can be implemented quickly and easily using existing city infrastructure to establish a grid of sensors and detectors to provide localized or wide area coverage. The approach provides a turnkey solution or smart city in a box that can be adapted to different situations and needs to provide communications functionality and/or a desired or customized functionality for a wide range of different applications.

The present invention is directed to a mobile light tower that utilizes multiple sources of energy to provide a highly energy efficient source of illumination. The lights of the light tower draw power from the energy stored in the batteries. During the day, solar energy can captured and stored in batteries. In times of cloud cover, or at night, wind energy can be captured and stored in the batteries. Additional alternative energy sources can also be incorporated. In the event that neither of these sources are sufficient, a fuel powered generator can be utilized to generate energy to be stored in the batteries.

Disclosed is a waterproof LED light string that provides outdoor lighting in a simple and reliable manner. Waterproof bulb assemblies are used with replaceable LED light sources. The bulb assemblies are easily suspended from a rope or wire, screwed to a support, or magnetically supported from a ferrous metal support. Duplicate circuitry in the LED light source allows the LED light source to be connected in either direction.

An outdoor lighting fixture, comprising:

a housing;

a light emitting diode (LED) board connected to the housing and comprising at least one LED light source; and a thermally conductive reflector operably connected to a front side of the LED board and having an opening to allow light emitted from the at least one LED light source to pass through, wherein the sheet metal reflector comprises an inner reflective surface and an outer surface, and wherein the inner surface reflects light from the LED light source towards an illumination area and the outer surface radiates heat from the LED board into ambient air.

A light-emitting device includes: a balloon, a light source disposed outside the balloon; and an optical fiber that connects the balloon and the light source and propagates light emitted by the light source. At least one of the balloon and the optical fiber becomes luminous by the light emitted by the light source.

A light fixture assembly configured to direct light outwardly and downwardly, while precluding the directing of light upwardly. The light fixture assembly comprises a housing, an LED light and a reflector. The LED light includes a mounting surface and a light emitting member. The mounting surface is coupled to the housing, and in particular on an inside surface of the upper side wall, with the light being directed in at least a downward direction. The reflector includes a second portion which is positioned within the inner cavity and below the LED light. The second portion is angled at least at 45° relative to a horizontal axis in an operational configuration. The reflector directs light imparted by the light emitting member in at least one of a downward and an outward direction, while precluding the directing of light imparted by the light emitting member in an upward direction.
