## Abstract

A light fixture, comprising a main body box (1), a guide rail head (2) positioned above the main body box (1) and capable of rotating relative to the main body box (1), and a light barrel (3) positioned on at least one side of the main body box (1) and capable of swinging up and down relative to the main body box (1), wherein a radiator (32) and a first light source (33) are arranged in the light barrel (3); the main body box (1) comprises a main body box top cover (11), a main body box bottom plate (12) and a main body box side plate (13) connected between the main body box top cover (11) and the main body box bottom plate (1); and the guide rail head (2) is pivotally connected to the main body box top cover (11), and the light barrel (3) is pivotally connected to the main body box side plate (13). The guide rail head of the light fixture can rotate in a horizontal direction relative to the main body box for adjustment, and the light barrel of the light can swing in a vertical direction relative to the main body box for adjustment, such that the irradiation angle and the irradiation range of the light barrel can be adjusted and various lighting requirements can be met.

## Claims

### Claim 1

A light fixture, wherein, the light fixture comprises a main body box, a guide rail head positioned above the main body box and capable of rotating relative to the main body box, and a light barrel positioned on at least one side of the main body box and capable of swinging up and down relative to the main body box;
a radiator and a first light source are arranged in the light barrel;
the main body box comprises a main body box top cover, a main body box bottom plate and a main body box side plate connected between the main body box top cover and the main body box bottom plate;
the guide rail head is pivotally connected to the main body box top cover, and the light barrel is pivotally connected to the main body box side plate;
wherein, the light barrel is connected to the main body box side plate through a light barrel pivot shaft;
wherein, the light barrel pivot shaft is configured in an upper part of the main body box side plate or in a lower part of the main body box side plate;
wherein, the main body box side plate is provided with a holding groove and the light barrel pivot shaft is rotatably configured in the holding groove;
