## Title
Lighting fixture assembly

## Abstract

A lighting fixture assembly includes a base having a plate and a peripheral wall which has recesses defined in an inner periphery thereof. The plate has connection slots in which V-shaped clamp members are respectively received. Each clamp member has a C-shaped connection end which includes an opening and two extensions extend from two ends of the connection end at an angle. Two parts each have an insertion and a frame is connected on the insertion. Each frame is connected with light tubes thereon. Each insertion has protrusions for being engaged with the recesses and positioning rods for being slidably inserted through the connection slots and engaged with the V-shaped clamp members. The two parts can be replaced by different shapes of parts.

## Background
FIELD OF THE INVENTION
The present invention relates to a lighting fixture assembly which is easily assembled and cooperated with multiple light tubes.
BACKGROUND OF THE INVENTION
A conventional lighting fixture for being cooperated with U-shaped light tubes generally includes a main body which is includes a plurality of connection ports for being connected with the U-shaped tubes. The body cannot be changed and the positions of the connection ports are fixed so that the users can only connect the U-shaped light tubes to the connection ports. The users do not have many options when purchasing in the market to have a lighting fixture that provides the users to assemble different shapes of frame for holding the light tubes.
The present invention intends to provide a lighting fixture which is composed of a base with connection slots and at least two frames are optionally connected with the connection slots and each frame can be connected with multiple light tubes.
SUMMARY OF THE INVENTION
The present invention relates to a lighting fixture assembly which comprises a base having a plate with connection slots defined therethrough and a peripheral wall extends perpendicularly from the plate. A plurality of recesses are defined in an inner periphery of the peripheral wall. A plurality of substantially V-shaped clamp members are received in the connection slots and each clamp member has a C-shaped connection end which includes an opening, and two extensions extend from two ends of the connection end at an angle. Each extension has a groove defined in an inside thereof.
A first part has a first insertion and a plurality of first protrusions extending radially from an outer periphery of the first insertion so as to be engaged with the recesses of the peripheral wall. A first frame is connected on a top of the first insertion and a plurality of first connection ports are defined in the first frame for receiving light tubes. A plurality of first positioning rods extend from an underside of the first insertion and are slidably inserted into the first connection slots. A second part has a second insertion and a plurality of second protrusions extend radially from an outer periphery of the second insertion. A second frame is connected on a top of the second insertion and a plurality of second connection ports are defined in the second frame so as to be connected with light tubes. A plurality of second positioning rods extend from an underside of the second insertion. The second protrusions are slidably engaged with the recesses and the second positioning rods are slidably inserted into the first connection slots. The first and second parts are simultaneously rotated an angle to move the first and second positioning rods into the C-shaped connection ends via the respective openings of the V-shaped clamp members.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIGS. 1-3, 4A, 4B, 5, 6A and 6B, the lighting fixture assembly of the present invention comprises a base 20 having a plate 21 and a circular peripheral wall extends perpendicularly from the plate 21. A plurality of recesses 23 defined in an inner periphery of the peripheral wall and a plurality of connection slots 22 are defined through the plate 21. A plurality of substantially V-shaped clamp members 10 are received in the connection slots 22 and each clamp member 10 has a C-shaped connection end 11 which includes an opening 12. Two extensions 13 extend from two ends of the connection end 11 at an angle so that the two extensions 13 have flexibility and can be pushed inward and outward. Each extension 13 has a groove 132 defined in an inside thereof. Each extension 13 of each of the V-shaped clamp members 10 has a first stub 14 which splits outward from the extension 13 and forms a first opening 131. The C-shaped connection end 11 of each of the V-shaped clamp members 10 has a second stub 112 which splits inward from the C-shaped connection end 11 and forms a second opening 111.
A first part 30 has a first insertion and a plurality of first protrusions 32 extending radially from an outer periphery of the first insertion. The first insertion includes a first connection surface 33 and a first ridge 331 extends from the first connection surface 33, and a first engaging groove 332 is defined in the first connection surface 33. A first frame 34 is a substantially V-shaped frame and connected on a top of the first insertion. A plurality of first connection ports 341 are defined in the first frame 34 so as to connect light tubes 50 as shown in FIG. 5. A plurality of first positioning rods 31 extend from an underside of the first insertion. The first protrusions 32 are slidably engaged with the recesses 23 and the first positioning rods 31 are slidably inserted into the first connection slots 22 and engaged with the grooves 132 of the extensions 13.
A second part 40 has a second insertion and a plurality of second protrusions 42 extend radially from an outer periphery of the second insertion. A substantially V-shaped second frame 44 is connected on a top of the second insertion and a plurality of second connection ports 441 are defined in the second frame 44. A plurality of light tubes 50 as shown in FIG. 5 are connected with the second connection ports 441. A plurality of second positioning rods 41 extend from an underside of the second insertion. The second insertion includes a second connection surface 43 and a second ridge 431 extends from the second connection surface 43, and a second engaging groove 432 is defined in the second connection surface 43. The first ridge 331 is engaged with the second engaging groove 432 and the second ridge 431 is engaged with the first engaging groove 332 so that the first and second insertions are matched with each other as a one piece.
The second protrusions 42 are slidably engaged with the recesses 23 and the second positioning rods 41 are slidably inserted into the first connection slots 22 and are engaged with the grooves 132 of the V-shaped clamp members 10. The first and second parts 30, 40 are then simultaneously rotated an angle to move the first and second positioning rods 31, 41 into the C-shaped connection ends 11 via the respective openings 12 of the V-shaped clamp members 10.
The first stubs 14 assist the V-shaped clamp members 10 to be positioned in the connection slots 22 and the second stub 112 is located between the first and second positioning rods 31, 41 to prevent the first and second positioning rods 31, 41 from being tangled to each other.
As shown in FIGS. 8-11, the first and second frames 34, 44 can be any shape and the number of the first and second connection ports 341, 441 can be varied as needed.
While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
