Modular solid state high bay lighting fixture
A modular solid state high bay lighting fixture is provided herein which includes at least two lighting modules, each including a body configured to define an open channel along one face thereof. A plurality of solid state light generating elements are located in the open channels of the bodies, with a lens or diffuser at least partly overlying each of the open channels. Bottom and upper plates extend between the lighting modules with the upper plate being spaced from, and at least partially overlying, the bottom plate so that a chamber is formed therebetween. A pair of endcaps are provided on opposite ends of the lighting modules. Advantageously, the subject invention allows for a solid state lighting fixture to be prepared in modular form which allows for both width and length adjustment.
1. A modular solid state high-bay lighting fixture comprising:
first and second bodies, each said body defining an open channel along one face;
a plurality of solid state light generating elements disposed within said open channels of said first and second bodies;
a first lens extending across said open channel of said first body;
a second lens extending across said open channel of said second body, said second lens being spaced from said first lens;
a bottom plate extending between, and in contiguous contact with, said first and second bodies; and,
an upper plate extending between, and in contiguous contact with, said first and second bodies, wherein said upper plate being spaced from, and at least partial overlying, said bottom plate so as to partially define a chamber between said first and second bodies.
2. A lighting fixture is in claim 1 , further comprising first and second endcaps formed to enclose therebetween said first and second bodies, said bottom plate and said upper plate.
3. A lighting fixture as in claim 2 , wherein said upper plate is unitarily formed with said first and second endcaps.
4. A lighting fixture as in claim 1 , wherein said first and second bodies have the same cross-section.
5. A lighting fixture as in claim 1 , wherein said first and second bodies each have a generally constant cross-section throughout the respective length thereof.
6. A lighting fixture as in claim 1 , wherein said first and second bodies are each provided with a plurality of protruding fins opposite said respective open channel.
7. A lighting fixture as in claim 1 , wherein a reflector is provided in at least said open channel of said first body, said reflector having one or more panels configured to reflect light emitted by said solid state light generating elements.
8. A lighting fixture as in claim 1 , wherein said first body is provided with mounting channels along edges of said open channel, said first lens being mounted to said first body with insertion into said mounting channels.
9. A lighting fixture as in claim 1 , wherein said first and second bodies are each provided with a secondary mounting channel, said bottom panel being edge supported by said secondary mounting channels.
10. A lighting fixture as in claim 9 , wherein said secondary mounting channels are each provided with a bead, said bottom panel having a curved edge formed to resiliently engage one of said beads to provide a rotatable connection therewith.
11. A lighting fixture as in claim 1 , wherein said bottom plate is generally coplanar with said first lens.
12. A lighting fixture as in claim 11 , wherein said second lens is generally coplanar with said first lens.
13. A lighting fixture as in claim 1 , wherein said first and second bodies are each provided with a ledge, said upper plate being secured to said ledges.
14. A lighting fixture as in claim 1 , further comprising a driver accommodated in said chamber, said driver being electrically coupled with said solid state light generating elements.
