The first driving device may be coupled to the reflective medium, the fixing column may pass through the second through-hole into the reflective medium, and the at least one first incoherent light source may be connected to the fixing column.

A ceiling fan light kit and a ceiling fan connecting module are provided. The ceiling fan light kit includes the ceiling fan connecting module, a light board, and a light cover module. The ceiling fan connecting module includes a mounting plate and a base. The mounting plate has a plurality of arc holes, a plurality of rotary fixing structures, and a plurality of backstop structures, and a placing hole and a fixing hole are respectively formed at two ends of each of the arc holes. The mounting plate has one of the rotary fixing structures and one of the backstop structures that are spaced apart from one another formed at two sides of each of the arc holes. The base has a bottom plate, a cooling portion, and a plurality of dowels that are respectively disposed in the placing holes.

The present invention an illuminated two-piece exhibit includes a first arcuate arm, a second arcuate arm joined to the first arcuate end at a proximate end, an intermediary arc extends between the first arcuate arm and the second arcuate arm at a distal end, a diffusor configured for receiving a light source, a centrally located receptacle extending between the first arcuate arm and the second arcuate arm, a window extending from the centrally located receptacle through the first arcuate arm and the second arcuate arm, the diffusor extending from said centrally located receptacle and at least partially through the window wherein the diffusor is configured for illumination by the light source.

An under-counter lighting system places a light-guide panel (LGP) or a set of LGPs under a countertop, or another such work surface, in order to backlight it. Specifically, a base layer is secured to a support, such as a cabinet. The base layer includes a support layer and a number of support posts attached to the support layer. An LGP layer includes the LGP or LGPs. Each of the LGPs has openings that correspond to positions of the support posts, such that the LGPs receive the support posts through their thicknesses. A countertop is secured to the tops of the support posts and may have a depending lip or other such feature sufficient to hide the base layer and the LGP layer. The resulting light, usually at least partially transmitted through the countertop itself, can serve as ambient light, task light, or accent light, depending on the installation.

An improved lighting system comprising a plurality of light units and incorporating safety features designed to reduce the likelihood of unwanted contact between the lighting system and aircraft, birds, or other flying objects. The safety features may include a lighting beacon coupled to one or more light units. A power source may be configured to provide power to both the light units and the lighting beacon. The safety features may also include a reflector coupled to one or more of the light units. The improved lighting system may comprise elongate members and brackets configured to attach the elongate members to a structure which may be a high mast structure such as a drilling rig.

A cross-shaped illuminating device, including a main body, and an illuminating unit, including a cross body having a cross shape disposed on at least a portion of the main body, a plurality of lights disposed on at least a portion of the cross body to illuminate a surrounding area, and a plurality of light covers disposed on at least a portion of the cross body to cover each of the plurality of lights.

An invisible, light-transmissive display system with a light resistant material is provided. Substantially invisible, tapered, light-transmissive holes are penetrated in a light transmissive pattern through at least a portion of the light resistant material using a laser beam having a focal width less than the smallest diameter of the tapered holes.

A power tool includes an output assembly, a housing, and an illumination device. The housing includes a main body, a grip, and a power supply connection portion. The power supply connection portion is configured to connect a power supply device. The main body and the power supply connection portion are respectively disposed at two ends of the grip. The illumination device is mounted to the power supply connection portion and includes a light-emitting element and a shield covering the light-emitting element. The shield has a light emission surface allowing light to be emitted therethrough. The power tool has a central plane, and a ratio of a size of the light emission surface in a width direction perpendicular to the central plane to a size of the power supply connection portion in the width direction is greater than or equal to 0.5 and less than or equal to 1.

Electronic light emitting flares and related methods. Flares of the present invention include various features such as self-synchronization, remote control, motion-actuated or percussion-actuated features, dynamic shifting between side-emitting and top-emitting light emitters in response to changes in positional orientation (e.g., vertical vs. horizontal) of the flare; overrides to cause continued emission from side-emitting or top-emitting light emitters irrespective of changes in the flare's positional orientation; use of the flare(s) for illumination of traffic cones and other hazard marking or traffic safety objects or devices, group on/off features, frequency specificity to facilitate use of separate groups of flares in proximity to one another, selection and changing of flashing patterns and others.

The present disclosure provides an artificial tree. The artificial tree includes a trunk including one or more trunk sections. The one or more trunk sections include a first trunk section including a first transmitter connected to a power source and configured to convert an input power received from the power source into an electromagnetic field, and a first receiver arranged proximate the first transmitter and configured to receive the electromagnetic field generated by the first transmitter and generate a first output current.
