CORNELIUS J. YOUNG FIG. 3
ATTORNEY United States Patent 3,240,928 FLUORESCENT LIGHTING ARRANGEMENT Cornelius J. Young, 9 Condit Road, Mountain Lakes, NJ. Filed Feb. 24, 1964, Ser. No. 346,667 6 Claims. (Cl. 24051.11)
This invention relates to indoor and outdoor lighting fixtures and more particularly to the construction of fluorescent outdoor lighting fixtures of the cantilever suspension type to render them easily manageable for assembly and quickly accessible for repair.
The primary object of this invention is to provide a cantilever arrangement for fluorescent lighting fixtures in which the greater portion of the weight of the fixture is concentrated adjacent or directly upon a supporting standard.
Another important object of this invention is to provide an improved construction for a fluorescent lighting fixture enabling detachment of a lamp-reflector housing from a separate ballast chamber without necessitating the removal of the ballast chamber form a support structure.
Another object of this invention is to provide a separate chamber for the lamps and the ballast unit of a fluorescent lighting fixture and to provide a removable or hinged lid for each chamber to enable ease in servicing.
With the foregoing and other objects in view, the invention resides in the following specification and appended claims, certain embodiments and details of construction being illustrated in the accompanying drawings in which:
FIGURE 1 is an exploded perspective view of a lighting fixture and support structure illustrating the detachable and accessible nature of an assembly within the contemplation of this invention;
FIGURE 2 is a plan view of detachable rectangular lamp and ballast housings and a support standard for attachment with the lighting fixture; and
FIGURE 3 is a plan view of a modified form of the invention illustration detachable fan-shaped lamp and ballast housings with a tubular passage in the ballast housing for insertion of a supporting pole.
Referring particularly to the drawings there is shown in FIGURE 1 a generally rectangular fluorescent lamp housing 10. Housing is provided with end Walls 11, side walls 12, top wall 13, and a movable, transparent bottom wall 14all components defining -a generally boxshaped enclosure. Housing 10 is also provided with suitable electrical and mechanical connecting members to allow attachment of fluorescent lamps 15 within the enclosure. Preferably, bottom wall 14 is rotatably supported along one of its edges to an adjacent side wall 12 or end wall 11 with means provided to form a secured closure with an opposite end wall or side wall. Although, bottom wall 14, as illustrated, is rotatably supported to housing 10 to facilitate access to the illuminating elements, it is recognized that wall 14 may be adapted for complete removal from lamp housing 10 or suitable means may be provided to permit sliding relationship between bottom wall 14 and lamp housing 10. Preferably, at least one side wall or end wall of lamp housing 10 is provided with holes 16 to receive connecting means such as bolts (not shown) to enable attachment to a separate ballast housing 17.
Ballast housing 17 is also shown in FIGURE 1 as a generally rectangular unit provided with end walls 18, side walls 19 and 19a, a bottom wall (not shown) and a top wall 20 adapted for pivotal movement about a side wall or an end wall. The components of ballast housing 17 form a generally box-shaped enclosure for encasement of electrical transforming means 21. At least 3,240,928 Patented Mar. 15, 1966 ice.
one side wall 19 or end wall 18 of ballast housing 17 is provided with holes 22 to receive connecting means such as bolt 48 for securing the ballast housing to a terminal connecting member 23 on an angularly disposed upper portion 24 of a generally vertical supporting standard 25. The opposite side wall or end wall of ballast housing 17 is provided with holes for receiving suitable connecting means to enable easy junction of lamps housing 10 to ballast housing 17 and apertures through which electrical connections may be passed between the transforming means to the connecting members for lamps 15 within the lamp housing 10.
Preferably, top wall 20, as illustrated in FIGURE 1, is hinged to allow rotation about side wall 19a furthest from the terminal connecting member 23. In the event that servicing of the transforming means is required, as a result of this manner of construction a person may easily attain access to the transforming means by boarding a ladder positioned against the supporting member 25. However, top wall 20 may be adapted for complete removal from ballast housing 17 or suitable means may be provided to permit sliding relationship between top wall 20 and housing 17.
The fluorescent lamp fixture of this invention, as generally described above, provides an improvement over the prior art relating to lamp fixtures and particularly the art relating to fixtures of the cantilever suspension variety in that ease in assembly and repair are obtained. Prior art devices of this nature have provided one housing for encasement of both the fluorescent lamps and their associated transformers. To meet the electrical requirements necessary to provide proper operation of the fluorescent lamps, the transformers are generally bulky and quite heavy. oftentimes, the approximate range in length of the housing itself may vary anywhere from four feet to six feet and, depending on the number of lamps for which the fixture is adapted, the weight of the dual housing may vary from 50 to pounds. The transformers, or ballasts to which they are commonly referred in the art, have been positioned at various locations within the dual housing, but at such a position within the housing that an undue moment of force is created around the supporting end of an upstanding structure.
Consequently, due to the size and great weight of the ballast, the material of which the fixture is constructed and the coupling between the fixture and the supporting structure are subjected to unwarranted stress. In the construction of the fixture, it is necessary to employ a heavy material capable of withstanding the stress. As a consequence, the overall weight of the unit is increased. The fixture is therefore quite awkward and difficult to handle, especially when it is to be positioned at an appreciable height above the ground. In the event that the dual unit requires servicing, such as adequately cleaning the inside of the fixture and/or refinishing the inner reflecting sur face, it is necessary to remove the combination lamp and ballast unit from the standard. Since the dual unit is quite heavy, in order to hold it during detachment from the standard or even to hold it during attachment to the standard, the services of a boom-truck are often necessary.
It is therefore within the contemplation of this invention to provide an arrangement for a fluorescent lighting fixture in which the ballast is mounted directly adjacent to the supporting-member or around the terminal of the supporting member. Thus, the largest portion of the weight of the fixture is concentrated at or directly upon the end of the supporting standard. As a result, the torque about the end of the supporting structure is substantially :reduced and the stress upon the coupling between the fixture and support-ing structure is minimized.
Furthermore, since the ballast is enclosed within a housing separate from a housing in which the fluorescent lamps are enclosed, the stress upon the material of the lamp housing will also be substantially reduced. Consequently, the lamp housing may be construced from a very light, narrow gauge, inexpensive material. By providing a separate, easily detachable, lightweight lamp housing, removing and servicing of the lamp portion of the fixture can be readily accomplished without removing the heavy transformer from the standard. Ease in mounting the fixture to the standard will also be attained.
Referring more particularly to FIGURE 2 there is shown a specific manner in which the lighting fixture of this invention may be mounted to a support member 26. At the terminus of member 26 there is provided a connecting plate 27 having apertures (not shown) through which. bolts 28 may be passed. Ballast housing 29 is shown as rectangular in shape and positioned such that the central axis of the generally longitudinal ballast 30 will be transverse to the central axis of the generally cylindrical support member 26 when the ballast housing is secured to the connecting plate 27. Apertures within side wall 31 of ballast housing 29 are provided to coincide with the apertures in connecting plate 27 of member 26. Depending on the thickness and strength of the material with which ballast housing 29 is constructed, a reinforcing plate 32 may be provided to back side wall 31. The reinforcing plate 32 is provided with apertures coincident with the apertures in side wall 31. Bolt members 28 and nut members 33 or any other suitable means may be employed to couple the ballast housing 29 to connecting plate 27. Similar coupling means, such as illustrated, consisting of bolt and nut members 34 and reinforcing plates 35 and 36 or any other suitable coupling means are provided to secure a generally rectangular lamp housing 37 to ballast housing 29. Provision of the reinforcing plate 36 is preferable since the material with which the lamp housing is constructed is generally of a lightweight substance and is generally capable of withstanding only a relatively light load.
In FIGURE 3 there is shown another manner of mounting the lighting fixture within the contemplation of this invention. The coupling means between connecting plate 38 and ballast housing 39 and between the ballast housing 39 and the lamp housing 49 are illustrated as a nut and bolt combination similar to coupling means illustrated in FIGURE 2. However, FIGURE 3 illustrates a ballast housing provided with a passage 41 therethrough and a support member 42 provided with a connecting plate 38 disposed inwardly from the terminus 43 of support member 42. The passage 41 through ballast housing 39 is of suflicient size to permit insertion of the end portion 44 of supporting member 42. When the ballast housing is mounted on the support member, connecting plate 38 preferably abuts side wall 45 of ballast housing 39 to enable the connecting means to establish a tight relationship between the connecting plate 38 and the side wall 45 of the ballast housing. Encased within the ballast housing 39 is a pair of transforming units 46. The central axis of transforming units 46 may be angularly disposed, or may be transverse or parallel to the central axis of tubular passage 41. A nut and bolt combination and a reinforcing plate 47 or any other suitable coupling means are provided to connect the lamp housing 40 to the ballast housing 39.
Although the illustrations indicate that the lamp housing may be mechanically coupled to the ballast housing, it is recognized that the ballast housing may be provided with a seating arrangement, such as a saddle, so that the ballast housing may sit upon the end portion of the supporting structure. The supporting structure may then be provided with two connecting plates, one similar to plate 38, as illustrated in FIGURE 3, and another similar to plate 27, as illustrated in FIGURE 2. The ballast housing could then be coupled to plate 38 while the lamp housing is separately coupled to plate 27. Conceivably, the ballast housing could thus be removed from the supporting structure without removing the lamp housing.
This invention may be embodied in other specific forms Without departing from the spirit or essential characteristics thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
