Technical Field

[0001] The utility model relates to the technical field of lighting fixtures, and more specifically, to an LED surface-mounted downlight. Background Art

[0002] Surface mounted downlights are a common lighting fixture. Different from common concealed downlights, surface mounted downlights are generally fixed on the outside of the wall or ceiling. Compared with tube lighting fixtures, LED downlights have lower lighting power and can provide better lighting effects. The downlights themselves can also be used as decorations and can be well integrated into the indoor environment. Therefore, they are widely used in various occasions such as hotels, homes, and cafes.

[0003] When installing lighting fixtures, operators often use LED surface-mounted downlights to provide indoor lighting. In actual use, although the existing surface-mounted downlights have basic lighting functions, the existing surface-mounted downlights generally cannot adjust the lighting direction at any time, so that the surface-mounted downlights cannot illuminate the area other than directly below the downlight according to the needs of the user, so they need to be improved. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides an LED surface-mounted downlight, which has the advantage that the lighting direction can be adjusted at any time.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: an LED surface mounted downlight, comprising:

[0006] A lamp tube, wherein both left and right sides of the outer surface of the lamp tube are fixedly connected with a rotating shaft;

[0007] A connecting plate, the connecting plate being movably sleeved on the left and right ends of the outer surface of the rotating shaft;

[0008] A rotating mechanism, wherein the rotating mechanism is arranged on the right surface of the connecting plate;

[0009] Among them, the rotating mechanism includes a No. 1 motor, which is fixedly installed on the upper side of the right surface of the connecting plate, and the other end of the No. 1 motor output shaft is fixedly sleeved with a No. 1 circular shaft, and the outer surface of the No. 1 circular shaft is fixedly sleeved with a driving bevel gear, and the outer surface of the driving bevel gear is meshingly connected with a driven bevel gear, the left surface of the driven bevel gear is fixedly connected to the right end of the rotating shaft, and the left surface of the driven bevel gear is movably connected to the right surface of the connecting plate, and the rotation of the driving bevel gear causes the driven bevel gear to rotate together with the rotating shaft and the lamp tube as a whole.

[0010] As a preferred technical solution of the utility model, a connection box is fixedly connected to the left surface of the connection plate, and a mounting plate is fixedly connected to the upper surfaces of the connection plate and the connection box, and mounting holes are provided on both sides of the upper surface of the mounting plate.

[0011] As a preferred technical solution of the utility model, an LED lamp holder is fixedly installed on the top of the inner surface of the lamp tube, the top of the LED lamp holder passes through the lamp tube and extends to the inside of the lamp tube, and the bottom end of the inner surface of the lamp tube is fixedly connected to transparent glass.

[0012] As a preferred technical solution of the utility model, a fixing plate is fixedly sleeved on the lower side of the outer surface of the lamp tube, a cleaning brush is movably connected to the left side of the lower surface of the fixing plate, the lower surface of the cleaning brush is fixedly connected to a movable frame, and the front and rear sides of the inner surface of the movable frame are movably connected to the outer surface of the fixing plate.

[0016] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0017] 1. The utility model sets a lamp tube, a rotating shaft, a connecting plate, a driving bevel gear and a driven bevel gear. When the No. 1 motor is running, the No. 1 circular shaft and the driving bevel gear will start to rotate. Since the driving bevel gear and the driven bevel gear are meshed with each other, the driven bevel gear will rotate under the meshing drive of the driving bevel gear.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figures 1 to 5 As shown, the utility model provides an LED surface mounted downlight, comprising:

[0027] A lamp tube 1, with rotating shafts 2 fixedly connected to the left and right sides of the outer surface of the lamp tube 1;

[0028] A connecting plate 3, the connecting plate 3 is movably sleeved on the left and right ends of the outer surface of the rotating shaft 2;

[0029] A rotating mechanism, which is arranged on the right surface of the connecting plate 3;

[0030] Among them, the rotating mechanism includes a No. 1 motor 4, which is fixedly installed on the upper side of the right surface of the connecting plate 3. The other end of the output shaft of the No. 1 motor 4 is fixedly sleeved with a No. 1 circular shaft 5. The outer surface of the No. 1 circular shaft 5 is fixedly sleeved with a driving bevel gear 6. The outer surface of the driving bevel gear 6 is meshingly connected with a driven bevel gear 7. The left surface of the driven bevel gear 7 is fixedly connected to the right end of the rotating shaft 2, and the left surface of the driven bevel gear 7 is movably connected to the right surface of the connecting plate 3. The rotation of the driving bevel gear 6 causes the driven bevel gear 7 to rotate together with the rotating shaft 2 and the lamp tube 1 as a whole.

[0031] When the No. 1 motor 4 is running, the No. 1 circular shaft 5 and the driving bevel gear 6 will start to rotate. At this time, due to the mutual meshing between the outer surfaces of the driving bevel gear 6 and the driven bevel gear 7, the driven bevel gear 7 will start to rotate driven by the driving bevel gear 6. At the same time, the rotation of the driven bevel gear 7 will also drive the rotating shaft 2, so that the rotating shaft 2 and the lamp tube 1 as a whole start to rotate with the rotating shaft 2 as the axis.

[0032] The left surface of the connecting plate 3 is fixedly connected to the connecting box 8, the upper surfaces of the connecting plate 3 and the connecting box 8 are fixedly connected to the mounting plate 9, and the upper surface of the mounting plate 9 is provided with mounting holes 12 on both sides.

[0033] The design of the mounting plate 9 and the mounting hole 12 facilitates the operator to install the lamp tube 1 as a whole.

[0034] An LED lamp holder 10 is fixedly installed on the top of the inner surface of the lamp tube 1 , the top of the LED lamp holder 10 penetrates the lamp tube 1 and extends to the inside of the lamp tube 1 , and a transparent glass 11 is fixedly connected to the bottom end of the inner surface of the lamp tube 1 .

[0035] When the LED lamp head 10 is in operation, the LED lamp head 10 will begin to emit light.

[0036] Among them, a fixing plate 13 is fixedly sleeved on the lower side of the outer surface of the lamp tube 1, a cleaning brush 15 is movably connected to the left side of the lower surface of the fixing plate 13, and a movable frame 16 is fixedly connected to the lower surface of the cleaning brush 15. The front and rear sides of the inner surface of the movable frame 16 are movably connected to the outer surface of the fixing plate 13.

[0037] When the moving frame 16 moves to the right, the cleaning brush 15 cleans the lower surface of the transparent glass 11 .

[0038] The outer surfaces of the front and rear sides of the fixed plate 13 are both provided with limiting grooves 14 , the inner surfaces of the limiting grooves 14 are movably connected to limiting blocks 17 , and the outer surfaces of the limiting blocks 17 are fixedly connected to the inner surfaces of the movable frame 16 .

[0039] The limit block 17 limits the movable frame 16 to ensure the stability of the movable frame 16 when it moves to the right as a whole.

[0040] A No. 2 motor 18 is fixedly mounted on the right surface of the fixing plate 13 , and a No. 2 round shaft 19 is fixedly sleeved on the other end of the output shaft of the No. 2 motor 18 .

[0041] When the second motor 18 is running, the second circular shaft 19 will start to rotate.

[0042] The outer surface of the second circular shaft 19 is fixedly sleeved with an active rod 20 , the other end of the active rod 20 is hinged with a driven rod 21 , and the other end of the driven rod 21 is hinged to the left surface of the moving frame 16 .

[0043] When the active rod 20 rotates, the driven rod 21 drives the moving frame 16 , so that the moving frame 16 as a whole starts to move under the limit of the limit slot 14 .

[0044] The working principle and use process of this utility model:

[0045] When the operator needs to adjust the lighting direction, the operator starts the No. 1 motor 4. As the No. 1 motor 4 runs, the No. 1 circular shaft 5 and the active bevel gear 6 begin to rotate. At this time, the driven bevel gear 7 begins to rotate under the meshing drive of the active bevel gear 6. At the same time, the rotating shaft 2 and the lamp tube 1 as a whole will also begin to rotate around the rotating shaft 2 as the axis driven by the driven bevel gear 7, which changes the overall lighting direction of the lamp tube 1 until the lamp tube 1 is aligned with the direction where lighting is required.

[0046] When the lower surface of the transparent glass 11 is stained with dust or stains, the operator starts the No. 2 motor 18. As the No. 2 motor 18 runs, the No. 2 circular shaft 19 and the active rod 20 begin to rotate. The rotation of the active rod 20 drives the driven rod 21, so that the driven rod 21 begins to rotate with the other end of the active rod 20 as the axis. At the same time, the other end of the driven rod 21 drives the entire movable frame 16, so that the cleaning brush 15 and the movable frame 16 begin to move toward the direction of the transparent glass 11 under the limit of the limit block 17. In this process, the cleaning brush 15 wipes off the dust and stains on the lower surface of the transparent glass 11, thereby ensuring the overall lighting effect of the lamp tube 1.
