Landscape lighting fixture with adjustable bollard shroud

Abstract

A landscape lighting fixture utilizes a cylindrical bollard shroud member which houses an electrical light source, e.g. an LED module. The shroud number extends upwardly from an elongated riser element. A vertically adjustable path hat support system affixed to a path hat circumscribes the shroud member, thereby allowing the path hat to be vertically adjustable in relation to the shroud member. The path hat and path hat support system can also be vertically adjustable along the riser element, without an attached shroud member. In either case, the adjustability of the path hat allows the lighting fixture to provide a wider or narrower light beam angle from the light source without adjusting the illumination from the light source.

Description

FIELD OF THE INVENTION

This invention relates to electrical landscape lighting fixtures and particularly to decorative lighting fixtures with adjustable components providing a variety of illuminating effects.

BACKGROUND OF THE INVENTION

The typical outdoor lighting system designed to illuminate and often to enhance the look of exterior landscapes, usually consists of a variety of different lighting fixtures. Each fixture in the system is designed to provide a specific illuminating effect. These effects can normally only be changed by increasing or decreasing the fixture's illumination by substituting different lighting sources or using dimmers or like components. Illumination effects cannot be altered by simple adjustment of and at the fixture itself.

SUMMARY OF THE INVENTION

It is thus the object of the present invention to provide a landscape lighting fixture with a bollard shroud which is easily and simply adjustable, in order to produce different lighting beam widths and thus a variety of lighting effects.

These and other objects are accomplished by the present invention, a landscape lighting fixture utilizing a cylindrical bollard shroud member which houses an electrical light source, e.g. an LED module. The shroud member extends upwardly from an elongated riser element. A vertically adjustable path hat support system affixed to a path hat circumscribes the shroud member, thereby allowing the path hat to be vertically adjustable in relation to the shroud member. The path hat support system with the path hat can also be vertically adjustable along the riser element, without an attached shroud member. In either case, the adjustability of the path hat allows the lighting fixture to provide a wider or narrower light beam angle from the light source without adjusting the illumination from the light source.

DETAILED DESCRIPTION OF THE INVENTION

Landscape lighting fixture 2 comprises elongated riser element 4 having upper end 6 and lower end 8. Clear cylindrical bollard shroud member 10 is located on and extends upwardly from upper end 6 of riser element 4. Shroud member 10 houses lighting source in the form of a directional LED module 12. Electrical wiring 14 extends from LED module 12 through riser element 4 to electrical connectors 15 and 17 extending from the wiring at lower end 8 of the riser element. Ground penetrating member 16 is also located and connected by threading at lower end 8 of riser 4. Likewise, LED module 12 is threadably connected to riser element 4 at the top of the riser element (see FIG. 6).

First connection means in the form of set screw 20 removably secures shroud member 10 to riser element 4 by rotation of Allen wrench 35. Second connection means in the form of path hat support system 22 affixes path hat 24 to shroud number 10. Path hat support system 22 comprises path hat armature 26 which circumscribes shroud member 10, a plurality of arm elements 28, 30, and 32, each upstanding from the path hat armature to path hat 24, and set screw connector 34 which removably secures the path hat support system and the path hat to the shroud member by rotation of Allen wrench 35. Path hat support system 22 can also be positioned directly around riser element 4, without utilizing an attached shroud member. In this case, set screw connector 34 would affix path hat support system 22 and path hat 24 to riser element 4. Thus, path hat support system 22 allows path hat 24 to be vertically adjustable along both shroud member 10, as seen in FIGS. 7-10, and riser element 4, as seen in FIGS. 11 and 12.

By vertically adjusting path hat 24, a wider or narrower light beam angle emanating from a light source is created without having to adjust the illumination from the light source. As best seen in FIG. 11, LED module 12 is the light source located within riser element 4. The higher path hat 24 is positioned along riser element 4, the wider the light beam angle 25. FIG. 12 illustrates that the lower path hat 24 is positioned along riser element 4, the narrower the light beam angle 27. Once the desired position of path hat 24 is attained, screw connector 34 is tightened to maintain this position.

When the present invention uses shroud member 10, it houses LED module 12, knurled cap with reflector 36 and diffuser 38. Shroud member 10a, itself, has a decorative nautilus design. It is contemplated that many different bollard shroud members with different decorative designs, e.g. 10b and 10c, can be utilized, as seen in FIGS. 18 and 19 respectively. The shroud members utilized in the invention can be decorative, like shroud members 10a, 10b, and 10c, or without decorative design, as illustrated by shroud member 10. However, the bollard shroud members which are used in accordance with the present invention are not to be considered restricted to those disclosed herein. It is contemplated that any shroud member, with decorative design or without, is encompassed within the scope of the invention.

Shroud members are interchangeable. For instance, removal of set screw 34 will allow path hat support system 22 and path hat 24 to be lifted off shroud member 10. A second shroud member 10a having the nautilus design, is next positioned over riser element 4 and secured in place by set screw 20, as illustrated in FIGS. 12-16. Path hat support system 22 can then be installed over shroud member 10a. Path hat support 22 adjusted is to the desired height. It is then affixed to that height by means of set screw 34.

Certain novel features and components of this invention are disclosed in detail in order to make the invention clear in at least one form thereof. However, it is to be clearly understood that the invention as disclosed is not necessarily limited to the exact form and details as disclosed, since it is apparent that various modifications and changes may be made without departing from the spirit of the invention.
