Definitions

  • This contrivance relates to a hang type lighting assembly for decoration particularly composed of a plurality of illumination units.
  • a light transmitting cover or globe to cover outside of respective illumination unit is provided.
  • luminance differs noticeably between near positions of the light source and the surroundings, and lamp image can hardly be eliminated and the improvement of illumination image is not very effective.
  • a decorative light assembly is known from US-A-3061715, which may be used to decorate Christmas trees and spell out words. It is formed from a plurality of interconnecting units, and strings of units may be flexed.
  • One form of unit comprises a spherical cover in two hemispherical pieces.
  • a tube which opens into the centre of the sphere extends away from the point on each hemispherical piece remote from the diameter defining the hemisphere.
  • the units are joined by plugging a tube from one spherical cover into a tube from the next.
  • Two electrically conductive connectors extend spaced apart within the tube, and extend across the internal cavity of the spherical cover and into the other tube of the cover.
  • a light bulb is supported by the connectors in the cavity, in electrical connection between the connectors.
  • the electrical connectors of the two covers are electrically connected.
  • the material of the spherical covers is relatively thin compared with the size of the cavities within the covers. It is not suggested in US-A-3061715 that the completed assembly could be hung or suspended, and it is not clear that this could be done without the units separating under the force of gravity.
  • FR-A-365362 discloses a lighting assembly in which the units each comprise a support member which holds a bulb, and metal electrical conductors pass through the support member, making electrical contact with the bulb and supplying power to it. Each electrical conductor extends beyond the edges of the support member and terminates in a hook. Units may be electrically connected together by engaging the hooked ends of the conductors of one unit with the hooked ends of the conductors of another unit. It is not explicitly stated in FR-A-365362 whether the hooking engagement of the electrical conductors is also intended to support the units nor whether the assembly of hooked together units is intended to be suspended.
  • an illumination unit and a lighting assembly as set forth in the claims.
  • An embodiment of the invention provides a hang type lighting fixture for decoration with which the illumination units connection work completes the electrical wiring work at the same time, yet the work is very easy, and changes in the combination of the illumination units after connection or cleaning is also easy, and the illumination image can be improved easily by eliminating lamp image of the light source.
  • the cover may be formed of glass.
  • the illumination units may be connected together by setting the upper hooks of one illumination unit on the lower hooks of another illumination unit positioned above the 1st illumination unit.
  • the conductive suspension members may provide both electrical connection and support for the illumination units, and in this way the connection work of the illumination units comprising the lighting assembly also serves as the electrical wiring work. Accordingly, changes in the layout or combination and cleaning work may be easier.
  • the light transmissive cover may reduce the image of the bulb and improve the illumination image.
  • FIG. 1 is a partially cut-away perspective view of an illumination unit for a suspended decorative lighting fixture embodying the invention.
  • One illumination unit is provided with two hooking members (1 and 2) of the two conducting wires. At the ends of said hooking members (1, 2), upper hooks (1a, 2a) and the lower hooks (1b, 2b) are provided respectively.
  • Two hooking members are held by a fixing member (4) made of an insulating material so as not to come in contact each other.
  • Two electrode wires of the bulb (6) are inserted into the fixing member (4) and are respectively put in contact with the hooking member (1) and (2), and the bulb (6) is held by the fixing member (4).
  • a cover or globe (3) made of light transmitting glass material is attached at approximately the center of the illumination unit.
  • Each cover part (3) is approximately in the shape of semi-circular cylinder with a dent (3a) near the center.
  • Two parts are mounted from both sides of the illumination unit so that the bulb and the fixing member (4) are fitted to said dent (3a), and a ring form spring (5) is fitted and fixed to the pheriphery of the parts (3).
  • Fig. 2 is a side sectional view showing composition of the main part of the illumination units for forming a hang type lighting fixture for decoration.
  • the bulb (6) and the fixing member (4) are positioned at the dent (3a) formed approximately at the center of the cover (3) composed of light transmitting glass material.
  • a groove not illustrated is formed at the part in contact with the hooking member (1) in the cover (3), and two cover parts (3) can be attached to the illumination unit by putting the respective inner sides in contact with the illumination unit.
  • the spring (5) formed in ring form is fitted to the groove (3b) formed on the peripheral surface of the cover (3) and the two parts are fixed by elasticity of said spring (5).
  • Fig. 3 is a front view showing condition of use of said hang type lighting fixture for decoration.
  • power voltage is supplied through the power line not illustrated.
  • the upper hooks (1a, 2a) of the illumination unit A are hooked, and source voltage is supplied to the hooking member of the illumination unit A when the two fittings are connected.
  • source voltage is supplied to the bulb connected to the hooking member by the electrode wires and the bulb glows.
  • source voltage is also supplied to the hooking member of the illumination unit B hooked to the lower hooks (1b, 2b) of the illumination unit A respectively by the upper hooks (1a, 2a). Accordingly, the bulb of the illumination unit B also glows in the same manner as the illumination unit A.
  • the illumination unit C hooked to the lower hooks (1b, 2b) of the illumination unit B by the upper hooks (1a, 2a).
  • the installation work of the hang type lighting fixture for decoration and the wiring work can be carried out at a time by connecting the hooks formed at both ends of the hooking member of each illumination unit one after another.
  • Installation of the hang type lighting fixture for decoration can be made simpler and alteration of combination after connection or cleaning work can also be made easily.
  • lamp image can be eliminated and illumination image can be improved by covering the bulb of each illumination unit with a cover made of light transmitting glass material. The work to detach the cover from the illumination unit at cleaning or bulb replacement can be made easier by fixing said globe with a spring.
