Abstract

The application discloses a lighting device. The lighting device includes a device body, having a first length in an axial direction; a plurality of lighting components arranged within the device body, wherein the lighting components is configured to emit light outward, such that a lighting area is generated by the lighting components; two support brackets being respectively connected to two ends of the device body in the axial direction; wherein each of the lighting component has different orientations, such that an angular coverage of the lighting area in a circumferential direction is at least 300°.

Claims (30)

1 . A lighting device, comprising:

a device body, having a first length in an axial direction;

a plurality of lighting components arranged within the device body, wherein the lighting components is configured to emit light outward, such that a lighting area is generated by the lighting components;

two support brackets being respectively connected to two ends of the device body in the axial direction;

wherein each of the lighting component has different orientations, such that an angular coverage of the lighting area in a circumferential direction is at least 300°;

wherein the support bracket comprises:

a bracket base contacted a support surface;

a support rod extending along a height direction from the bracket base;

a connecting component fitted on the support rod;

wherein the connecting component is detachably connected to one of the end of the device body in the axial direction; and

wherein the connecting component is capable of being fixed at different heights of the support rod to adjust a distance between the device body and the support surface.

2 . The lighting device according to claim 1 , wherein the device body comprises:

a main body frame provided with a plurality of accommodating slots extending along the axial direction; wherein one lighting component is confined within one accommodating slot;

a plurality of light guides; wherein one light guide covers over one accommodating slot to envelope the lighting component above;

two end structures being respectively fixedly connected to two distant ends of the main body frame in the axial direction;

wherein the end structures are detachably fixedly connected with the connecting components.

3 . The lighting device according to claim 2 , wherein the lighting component comprises a substrate and several LED diodes integrated on the substrate.

4 . The lighting device according to claim 3 , wherein the accommodating slot is compatible with the substrate and the substrate is detachably locked and fixed in the accommodating slot by one or more fasteners.

5 . The lighting device according to claim 2 , wherein the light guide is snap-connected to the main body frame.

6 . The lighting device according to claim 5 , wherein the main body frame comprises:

an internally hollow frame, wherein the internally hollow frame is rectangular in shape and formed by enclosing a bottom surface, a top surface, a first side and a second side; and the bottom surface is close to the support surface, while the top surface is the surface away from the bottom surface;

three accommodating components being connected to the top surface, the first side, and the second side respectively through three extension components;

wherein one accommodating component is provided with one accommodating slot.

7 . The lighting device according to claim 6 , wherein the accommodating components have a first surface and a second surface mutually opposed to the first surface, and the accommodating slot is formed on the first surface.

8 . The lighting device according to claim 7 , wherein two edges of the second surface of the accommodating component are provided with two step surfaces extending along the axial direction and the light guide is provided with a snap-fit, which is engaged with the step surface.

9 . The lighting device according to claim 7 , wherein the light guide is arc shaped.

10 . The lighting device according to claim 2 , wherein each end structure is provided with an electrical connection interface facing the support surface.

11 . The lighting device according to claim 2 , wherein the lighting components are connected by a plurality of interconnecting cables, and the interconnecting cables are less than a predetermined length.

12 . The lighting device according to claim 2 , wherein the connecting component has a fixing plate extending outward along the axial direction and the end structure is provided with a receiving groove compatible with the fixing plate;

wherein the fixing plate is accommodated in the receiving groove to restrict a relative movement in the height direction between the end structure and the connecting component.
