An illumination device includes a plurality of light panels facing in different directions and having light emitting elements, a user-operable power switch, an orientation detector for detecting the current orientation of the illumination device, and a controller for receiving information from the orientation detector and the user-operable power switch, and controlling electrical power to the light emitting elements based on such information. A timer, used for automatic shutoff and/or delayed-on functionality, might also be included. The controller is configured to operate in one or more different operational modes, which can be preset and/or user-selectable.

Lamp with LED light bulb

A lamp includes a light fixture mounted on a pole. The light fixture includes a transparent or translucent housing, and a solar energy collecting portion mounted on the light fixture. The solar energy collecting portion includes a top solar photovoltaic panel and side solar photovoltaic panels for collecting and converting incident solar energy to electricity. An electrical power source is mounted on the solar energy collecting portion. At least one LED light bulb is mounted on the base. The LED light bulb includes one or more LED lights mounted on a substrate provided with electrical wiring and housed in a transparent or translucent bulb enclosure. The substrate is mounted at one end of a slender stem.

Light emitting device

A light emitting device includes at least one light emitting unit configured to emit light, a body unit supporting the at least one light emitting unit, and a support unit disposed on the body unit defining a light emitting position of the at least one light emitting unit. The support unit has a conical shape and is configured to support the at least one light emitting unit.

System for directional control of light and associated methods

A lighting device for emitting light in selective directions including a light source structure member, a plurality of lighting devices attached to the light source structure member, a controller, a power supply, and an optic carried by the light source structure member and including a plurality of facets. Each light source of the plurality of light sources may be positioned such that light emitted thereby is emitted through a facet of the plurality of facets of the first optic. Each facet of the plurality of facets may be configured to redirect light in a direction that is unique from the other facets of the plurality of facets. Additionally, the controller may be configured to selectively operate each light source of the plurality of light sources. Multiple pairs, or combinations, of light source structure members and optics may be included.
