Application May 8, 1939, Serial No. 272,515

1 Claim.

This invention relates to an electric light flxture especially adapted for the use of fluorescent lamps, and has for the primary object the provision of a device of this character wherein obstructions to the light rays from the lamps will be reduced to -a minimum and permit the rays of light to extend unobstructedv upwardly, downwardly and horizontally to give full lighting of the work surface or the floor, ceiling and walls 10 similar devices and undesirable shadows within the room or in other words permit the entire room to be illuminated to the maximum amount.

With these and other objects in view, the invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which Figure 1 is a perspective view illustrating an electric light fixture constructed in accordance with my invention.

Figure 2 is a bottom plan view same.

Figure 3 is a fragmentary perspective view illustrating one of the corner brackets of the .fixture. 30 Referring in detail to the drawings, the numeral 5 indicates a casing which may be of any desired design and size and is equippedwith a ceiling attaching suspension medium 6 whichalso may be of any desired design. In this instance, the medium 6 is in the form of a chain or flexible element 1 having the usual ceiling attaching'flxtu're 8 so that the casing 5 will be supported in a suspended position from the ceiling. The casing 5 is for the purpose of housing electric feed conductors as well as a support for a control switch 9.

Extending radially from the casing 5 are supporting arms Ill of hollow formation having downwardly directed end portions H equipped with removable caps or nuts l2 to permit mounting on the end portions corner brackets I3. It is to be understood that the supporting arms I radiate horizontally from the casing preferably adjacent the lower end of the latter.

Each supporting bracket l3 includes angularly related portions M of channel construction in which are mounted conventional electric sockets [5 to receive and support fluorescent electric lamps l6. By reference to Figures 1 and 2 it 55 will'be seen that the lamps l6'are supp'orted by .the corner brackets in substantially rectangular shape. However, this shape may be varied by a rearrangement of the arms and corner brackets -without departing from the spirit and scope of go this invention. 4

illustrating the of a room, eliminating the use of reflectors and extended thereto by way of the hollow arms so as to be concealed from view and further to provide a safety factor.

The fluorescent lamps supported by the device and similar devices and permits the entire room in which the device is located to be illuminated substantially free'of shadows.

Other types of tubular electric lamps may be employed successfully with this device as its use is not necessarily restricted to a fluorescent type of lamp.

. By referring to Figure 3 it will be seen that each corner bracket "l3 has certain walls thereof cut away for the purpose of exposing the sockets l5 so that the ends of the terminals of fluorescent lamps may be readily placed in and removed from said sockets, the other walls concealing the sockets and connections thereof with the lamps from positions exteriorly of the fixture.

While I have shown in the drawings a specified number of lamps grouped in a certain configuration it is to be understood that the number of lamps. may be varied and the grouping thereof also varied through minor rearrangement of the supporting arms on the casing, it still being understood that the supporting arms are so positioned as to not obstruct the rays of light from the lamps either upwardly, downwardly or horizontally outwardly of the fixture.

It is believed that the foregoing description when taken in connection with the drawings will fully set forth the construction and advantages of my invention to those skilled 'in the art to which such device relates, so that further detailed description will not be required.

Havingdescribed the invention, I claim:

An electric light fixture comprising a casing, a ceiling supporting means for said casing, arms extending radially from said casing, and including downwardly curved end portions, brackets removably mounted on the end portions of said arms and each including angularly related portions of channeled formation having certain walls thereof cut away,electric sockets mounted insaid brackets. and fluorescent lamps received by the sockets and extending outwardly of the brackets by way of the cuts-away walls thereof and grouped outwardly of thearms and about the casing.
