Abstract

An angle adjustment mechanism for LED bar lighting includes a lamp body, two end covers arranged two ends of the lamp body along an axial direction thereof, two lamp frames respectively mounted on the two threading pipes, two wheel gears respectively fixed on the two lamp frames, two outer end caps fixed and covered on the two end covers, respectively, and at least two stopping plates respectively received in the two lamp frames. Each of the two end covers includes a threading pipe extending along the axial direction of the lamp body. Each of the two wheel gears includes a plurality of gear teeth taken along a radial direction thereof and rotating around the threading pipe. Each of the stopping plates provides at least one stopping tooth which is coupling to the gear teeth.

First claim

What is claimed is:

1 . An angle adjustment mechanism for LED bar lighting, comprising:
a lamp body; two end covers respectively arranged two ends of the lamp body along an axial direction thereof, each of the two end covers comprising a threading pipe extending along the axial direction of the lamp body; two lamp frames respectively mounted on the two threading pipes; two wheel gears respectively fixed on the two lamp frames, each of the two wheel gears comprising a plurality of gear teeth along a radial direction thereof and rotating around the threading pipe; two outer end caps respectively fixed and covered on the two end covers; and at least two stopping plates respectively received in the two lamp frames, each of the stopping plates providing at least one stopping tooth which is coupling to the gear teeth.

2 . The angle adjustment mechanism for LED bar lighting as claimed in claim 1 , wherein the outer end cap comprises a receiving chamber, the threading pipe and the wheel gears are received in the receiving chamber.

3 . The angle adjustment mechanism for LED bar lighting as claimed in claim 2 , wherein the stopping plate is a straight plate and is fixed in the receiving chamber.

4 . The angle adjustment mechanism for LED bar lighting as claimed in claim 3 , wherein the outer end cap comprises two mounting grooves spaced apart from each other, the two ends of the straight plate are slidably inserted into the two mounting grooves, respectively.

5 . The angle adjustment mechanism for LED bar lighting as claimed in claim 2 , wherein the stopping plate comprises an arc-shaped portion, and two installation portions arranged both ends of the arc-shaped portion, respectively, the outer end cap comprises two mounting grooves spaced apart from each other, the two installation portions are slidably inserted into the two mounting grooves, respectively.

6 . The angle adjustment mechanism for LED bar lighting as claimed in claim 1 , wherein the stopping plate is made of resilient material.

7 . The angle adjustment mechanism for LED bar lighting as claimed in claim 1 , wherein the wheel gear comprises a mounting portion in one end thereof along an axial direction of the wheel gear, and at least one ear extending along the radial direction of the wheel gear, the lamp frame provides a through hole disposed on the mounting portion, and at least one open configured for receiving the ear.

8 . The angle adjustment mechanism for LED bar lighting as claimed in claim 7 , wherein the through hole and the open are closely fitted with the mounting portion and the ear respectively so as to fix the relative position between the wheel gear and the lamp frame.

9 . The angle adjustment mechanism for LED bar lighting as claimed in claim 1 , wherein since the gear teeth of the wheel gear are provided in the radial direction thereof, the stopping plate cooperates with the wheel gear in the radial direction thereof so as to increase the coupling tightness therebetween and prevent from invalidating the angle adjustment mechanism as the installation interval becomes larger.

10 . The angle adjustment mechanism for LED bar lighting as claimed in claim 1 , wherein when the outer end cap drives the stopping plate around the threading pipe to rotate, the stopping plate will be switched between the deformed state and the normal state and while the stopping teeth is coupled to different gear teeth of the wheel gear so that the angle adjustment of the light emitting direction of the lamp body can be achieved.

11 . The angle adjustment mechanism for LED bar lighting as claimed in claim 1 , wherein when the lamp frame is rotated about the threading pipe, the lamp frame causes the wheel gear to rotate together around the threading pipe.
