1 Claim. 1

This invention relates generally to lighting units and more particularly to a fioodlight unit for illuminating the area symmetrically about the base of the light support and in projected areas extending therefrom.

A fioodlight comprising this invention may be advantageously used for the lighting of service stations, parking lots, freight transfer depots and the like. The principal object of this invention is the provisionof a floodlight arranged When supported in the air to provide an uninterrupted symmetrical light pattern at the base of the support.

Another object is the provision of a fioodlight arranged to project an uninterrupted symmetrical light at the base of its support and also provide an extended light pattern extending from the base in a predetermined direction.

Another object is the provision of a floodlight arranged to project a symmetrical light pattern at the base of its support.

Another object is the provision of a fioodlight arranged to project a continuous predetermined light pattern which is symmetrical at the base of its support.

Other objects and advantages appear hereinafter in the following description and claim.

A practical embodiment illustrating the principles of this invention is shown in the accompanying drawing wherein:

Fig. 1 is a sectional view of a fioodlight com prising this invention.

Fig. 2 is a sectional view taken on the line 22 of Fig. 1.

Fig. 3 is a perspective view of the floodlight comprising this invention.

Fig. 4 is a view illustrating a light pattern that may be produced by the floodlight comprising this invention.

Referring to the drawings, the floodlight casing I6 is supported from the standard I I which is preferably made of a single pipe stem preferably rising from theground orsupported onarelatively small independent structure around which it is desirable to provide a pattern of light of uniform intensity. The standard I I may be set in a concrete island such as found in a gas station or it may be supported on the top of a structure such as a gasoline pump. The upwardly extending pipe standard II is arranged to be inserted into the socket member I2 of the floodlight base I3 Which is preferably cast from a suitable material. The base I3 is provided with the horizontally disposed bottom portion I4 from which the integral socket I2 depends. The standard II is provided with a threaded hole I5 adjacent the upperend thereof arranged to receive the bolt I6. The lower portion of the socket I2 is provided with the slot II for the purpose of receiving the stem of the bolt I6 when the socket of the base I3 is inserted over the end of the standard The slot I'I may be guided down over the stem of the bolt I6 and when the latter is tightened against the lock washer I8 the base becomes secured to the upper end of the standard I I.

The horizontal section I4 of the base I3 is joined integrally with the upwardly and outwardly extending faces 20 and 2| which extend to the vertically disposed ends 22 and 23. The sections of the base I3 are closed by the sides 24 and 25 and provide an upwardly open hollow base member, the upper perimetral surface of which is substantially rectangular.

The central portion of the sloping faces 26 and 2| are provided with the circular beveled openings 26 and 21 which are outlined by the circular ridges 28 and 29 forming annular seats or sockets for the globes of the sealed in beam lights 30 and 3 I.

The lamp base cover 32 is substantially rectangular in shape and is provided with a substantially flat top 33 with an outwardly and downwardly curved wall 34 matching the perimetral edge of the upwardly extending rectangular wall of the base I3. The perimetral edge of the cover 32 is provided with an offset skirt 35 providing a lapped joint arranged to fit down around the perimetral surface of the top of the base member I3. The cover 32 may be secured by the screws 36 which pass through threaded openings in the skirt 35 and clamp against the surface of the base I3 thereby providing a complete closure member or light casing which does not permit the entry of the elements.

The bracket 31 is secured by means of the bolts 38 to the inside of the cover 32 and is provided with two angularly disposed portions 40 and 4| which areseparated by an intermediate portion 4-2 and arranged to receive the electric light sockets 43 and 44 which are secured to the bracket by the screws 45. The sections 40 and 4| of the bracket 31 are formed to properly align the axis of the sockets 43 and 44 with their respective sockets 26 and 21 in the faces 20 and 2| of the base I3. The bracket is also formed so as to properly lock the light sockets 43 and 44 at the proper distances from the faces 20 and 2| so as to permit the glass bulb section of the lamps 3|] and 3| to become properly seated in the sockets 26 and 21 when the base of the lamps 3 are screwed to substantially their full depth into the electric sockets 43 and 44.

The cover 32 is arranged to support three inde pendent light holders 46, 41 and 48 which are mounted on the swiveled stems 50, 5| and 52 attached to or formed integral with the top 33 of the cover"; Each f the independentilight holdeers 46, 4 1 and 48 may: be arrangedtto; receive sealed-in beam lights 53, 54 and 55 which may be either spot or floodlight type. If spotlights:- are employed the independentlight.holderscmay be adjusted to direct the beamxotthe; spottoni any desired portion around the area to be lighted? On the other hand if floodlights are employed they may be directed so as to provideanextendedr' pattern of light on one sideot the.floodlight,

casing III, the independent beams being arranged to intersect a portion of the beams from the" floodlights 30 and 3| to produce a continuous lightxpattern such as illustratedrimFig, L-wherein thei fioodlights 3i and. 32V produce the, patterns 56 and 5-1 and the floodligl'its 53=andt55procluce the. patterns 581, and t 5 91;. and the centermostg light 5.4 produces: the pattern 60.- When the floodlights are: adiustediand, lighted the pattern. such; as shown in .Eig i may beproduced.

Then-light holders 46; 4?! and481may thus:- bedirected to project a= lightpattern .in; any, direc tion from the lights l0: andsuchipatternsemayg or I I claim:

A floodlight fixture comprising a box, two opposite side walls of said box having downwardly and inwardly sloping faces, an annular seat defining an opening in each sloping face to be engaged by a floodlight glass bulb larger in diameter than said'annularrseat'; an electric socket to receiveithebase of each floodlamp, and means to mount the electric sockets within the box on the same axis as that of the corresponding annulari seat and to h01d the glass bulb against its seat toh-makecit coact and produce a predetermined=floodlightypattern of a pair of overlapping ellipses when the floodlamps are lighted.
