Abstract

The present disclosure provides a lighting fixture. The lighting fixture includes a light tube, a light source, a circuit board, and a stand. The light tube is provided with a guide rail used to clamp a substrate. The stand includes a first support bracket and a second support bracket that are opposite to each other, and a connection crossbeam. The first supporting bracket and the second supporting bracket are connected to two sides of the circuit board, and the connection crossbeam provides a support force to the first supporting bracket and the second supporting bracket.

First claim

The invention claimed is:

1 . A lighting fixture, comprising:
a light tube comprising a cavity and a guide rail located on an inner sidewall of the cavity, the guide rail extending along a length direction of the cavity; a light source and a circuit board located within the cavity, the light source being electrically connected to a circuit of the circuit board, the circuit board being mounted in the guide rail along a length direction of the cavity; and a stand comprising a first support bracket and a second support bracket that are opposite to each other, and a connection crossbeam between the first support bracket and the second support bracket, one end of the connection crossbeam being connected to the first support bracket and other end of the connection crossbeam being connected to the second support bracket, and wherein the first supporting bracket is connected to one side of the circuit board and the second supporting bracket is connected to other side of the circuit board in a width direction of the circuit board.

2 . The lighting fixture according to claim 1 , wherein the first support bracket comprises:
a first support column and a second support column located on two sides of the connection crossbeam, and a connection part connected to the first support column and the second support column, and, in the width direction of the circuit board, one end of one or both of the first support column and the second support column is connected to one side of the circuit board.

3 . The lighting fixture according to claim 2 , wherein:
the first support column comprises a first column and a buckle located at one end of the first column, and the circuit board comprises a corresponding buckle hole, and the buckle is snap-fitted with the buckle hole.

4 . The lighting fixture according to claim 3 , wherein:
the second support column comprises a second column and a plug located at one end of the second column, and the circuit board comprises a corresponding plug hole, and the plug is connected to the plug hole with an interference fit.

5 . The lighting fixture according to claim 2 , wherein:
the second support column comprises a second column and a plug located at one end of the second column, and the circuit board comprises a corresponding plug hole, and the plug is connected to the plug hole with an interference fit.

6 . The lighting fixture according to claim 2 , wherein:
the connection part comprises a first screw hole with an opening towards the circuit board, and the circuit board comprises a second screw hole corresponding to the first screw hole, the lighting fixture further comprising a screw, and the screw passes through the second screw hole and the first screw hole in sequence and is bolted to the connection part.

7 . The lighting fixture according to claim 2 , wherein the cavity comprises a first bearing shoulder and a second bearing shoulder being inwardly concave and facing each other; and
the stand further comprises a first bearing boss connected to the first support bracket and a second bearing boss connected to the second support bracket, the first bearing boss and the second bearing boss extending away from the connection crossbeam, the first bearing boss is mounted on the first bearing shoulder, the second bearing boss is mounted on the second bearing shoulder.

8 . The lighting fixture according to claim 7 , wherein:
the first bearing boss comprises a first sub-boss and a second sub-boss, and, in an extension direction of the connection crossbeam, one end of the first sub-boss abuts against the first bearing shoulder, and the other end of the first sub-boss is connected to the first support column, one end of the second sub-boss abuts against the first bearing shoulder and the other end of the second sub-boss is connected to the second support column; and the second bearing boss is a structure with mirror symmetry or central symmetry with the first bearing boss.

9 . The lighting fixture according to claim 1 , wherein the second support bracket is a structure with mirror symmetry or central symmetry with the first support bracket.

10 . The lighting fixture according to claim 1 , wherein the circuit board comprises a substrate and an electrical components is located on the substrate, and the first support bracket, the second support bracket and the connection crossbeam form an accommodation space with a door-frame structure, and the accommodation space accommodates the electrical components.

11 . The lighting fixture according to claim 1 , further comprising two end caps snap-fitted with two ends of the cavity, wherein:
each end cap of the end caps comprises an end groove opening towards the light tube, an end of the cavity protrudes into the end grooves, each end cap of the end caps further comprises two clamping members opposite in a circumferential direction of the end cap, each of the clamping members comprises a clamping plate and two limiting pieces located on two sides of the clamping plate in the length direction of the cavity, and an end of the circuit board in the length direction of the cavity is inserted into a clamping groove formed by the clamping plate and the two limiting pieces.
