A lamp assembly includes a central holder attached to and disposed under the ceiling fan and having an electric wire passage, and several circumferentially equidistant illuminating units extending radially from the central holder. Each of the illuminating units includes a tubular connecting rod attached to the central holder, a rotary member connected rotatably to the connecting rod and capable of being locked on the connecting rod, a lamp equipped with an electric plug, and a reflection lamp shield connected removably to the rotary member and positioned over the lamp. The tubular connecting rod has a radial inner end fastened to and extending radially from the central holder, a central bore formed through the connecting rod in communication with the electric wire passage, and a radial outer end. The rotary member has a radial inner end connected rotatably to the radial outer end of the connecting rod, and a radial outer end equipped with an electric socket in which the electric plug is engaged. An electric wire can be passed through the electric wire passage of the central holder and through the central bore of the connecting body to couple with the rotary member.
A ceiling fan includes a plurality of fan blades radially secured to a motor shaft of a driving motor of the fan, each fan blade fixed with a holographic recording plate thereon pre-recorded with holograms of many sets of interference patterns of colorful decorative features within the recording plate, whereby upon a rotation of the fan blades as driven by the driving motor as being illuminated by a plurality of lamps, the patterns of color features recorded in each holographic recording plate will be observed with diversified color changes of the decorative features and superimposed decorative feaures with respect to a rotating angle as rotated by each fan blade, thereby enriching an optical decorative effect with simpler production, easier operation and minor maintenance problems of the fan.
This invention provides a high-output industrial light fixture that employs a plurality of commercially available fluorescent light sources in an array of adjustable arm assemblies each housing one or more light sources (fluorescent bulbs) in an associated reflector box or other source housing structure. By adjusting the arm assemblies, a more-precise spread of light onto the target surface can be achieved. Arm mounting brackets can be provided with one or more locking positions to facilitate multi-position angular placement of each individual arm. A plurality of arm assemblies can be provided around a center housing or hub, each directed outwardly in a radial direction from a central point or axis of the center housing/hub. Each arm's source reflector box/source housing structure can be located to project light either downwardly or upwardly and can be angled at a plurality of angular adjustment positions with respect to the center housing in each of the upward and/or downward positions. The bottom surface of center housing remains unobstructed (with arm assemblies extending away from it) so that cameras, sensors and other devices can be provided thereon. In an alternate embodiment, the reflector box/source housing structure for containing each light source can be mounted so as to extend transversely to a radial direction from the center. Accordingly, each box is located at a radial spacing from the center and extends substantially perpendicularly with respect to the radius, so as to define a polygon of reflector boxes around the center.
A nail-driving tool includes a body and an illumination device detachably mounted to the body. The body includes a plurality of engaging members formed thereon, and the illumination device includes a casing having an engaging groove for releasably engaging with one of the engaging members of the body.
A new and improved illuminated blade, ceiling fan apparatus includes a circular planar electrical contact assembly which includes a first circular planar conductor and a second circular planar conductor spaced from the first planar conductor such that the first planar conductor and the second planar conductor are not in electrical contact with each other. A brush contact assembly includes brushes for providing sliding electrical contact with the first planar conductor and the second planar conductor when there is relative rotation between the circular planar electrical contact assembly and the brush contact assembly. Respective sources of illumination, e. g. neon lamps, supported by the fan blade assemblies are in circuit with the circular planar electrical contact assembly and the brush contact assembly, such that the sources of illumination are energized when the brush contact assembly is in electrical contact with the first circular planar conductor and the second circular planar conductor. The fan blade assemblies may include blade members which include hollow interiors and are made from transparent materials. The sources of illumination are housed within the hollow interiors of the transparent blade members. A partially opaque and partially transparent design is supported by a transparent blade member, such that, when a source of illumination is energized, the partially opaque and partially transparent design is provided with backlighting. Either the first circular planar conductor or the second circular planar conductor includes a discontinuous circular conductive path. The discontinuous conductive path provides intermittent illumination.
A pull chain light assembly that attaches to a pull chain for the lamp portion of a ceiling fan. The pull chain light assembly is actuated by a light sensitive switch that turns on a light emitting diode when the amount of light in a room falls below a predetermined level. The pull chain light assembly employs a long lasting lithium battery as its power source.
