Specific embodiments
[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.
[0021] Please refer to Figures 1 - 6 , the present utility model provides a technical solution: a conference lamp with adjustable angle, including a mounting plate 1 and a lamp shade 2. An angle adjustment component 5 is arranged between the mounting plate 1 and the lamp shade 2. A through groove is opened at the bottom of the lamp shade 2, and a light-transmitting cover 3 is fixedly installed on the inner wall of the through groove. An LED lamp board 4 is rotatably arranged in the lamp shade 2. There are two LED lamp boards 4, and the two LED lamp boards 4 are symmetrically distributed front and back in the lamp shade 2. A range adjustment component 6 is arranged between the two LED lamp boards 4. A cylindrical LED lamp 7, a plate-shaped LED lamp 8, and a first reflector 9 are fixedly installed on the opposite side of the LED lamp board 4. The cylindrical LED lamp 7 is close to the bottom end of the LED lamp board 4, and the first reflector 9 is close to the top end of the LED lamp board 4. By adjusting the angle of the lamp shade 2 through the angle adjustment component 5, the function of adjusting the irradiation angle is realized. By adjusting the opening and closing angle of the two LED lamp boards 4 through the range adjustment component 6, when the two LED lamp boards 4 are close together, the range is the smallest, and only the cylindrical LED lamp 7 can be used for irradiation. As the opening and closing angle of the LED lamp board 4 becomes larger, while the plate-shaped LED lamp 8 is exposed, the two cylindrical LED lamps 7 move away from each other, that is, the irradiation ranges of the two cylindrical LED lamps 7 are gradually staggered, thereby increasing the irradiation range. At the same time, the first reflector 9 is used to reflect the light of the cylindrical LED lamp 7 and the plate-shaped LED lamp 8, so that more light can be emitted from the light-transmitting cover 3;
[0022] The angle adjustment component 5 includes a fixed seat 501, which is fixedly installed at the bottom of the mounting plate 1. A first motor 502 is fixedly installed on the outer wall of the fixed seat 501. The output end of the first motor 502 is fixedly installed with a first rotating shaft 503. The first rotating shaft 503 passes through the outer wall of the fixed seat 501 through a bearing. A rotating seat 504 is fixedly installed on the outer wall of the first rotating shaft 503. The rotating seat 504 is fixedly installed on the top of the lamp cover 2. By driving the first rotating shaft 503 to rotate through the first motor 502, the rotating seat 504 is driven to rotate, and the rotation of the rotating seat 504 drives the lamp cover 2 to rotate, realizing the change of the orientation of the lamp cover 2, and thus adjusting the irradiation angle;
[0023] The range adjustment component 6 includes a second motor 601 and a second rotating shaft 602. The outer wall of the second rotating shaft 602 is fixedly connected to the inner wall of the top end of the LED lamp board 4. The right end of the second rotating shaft 602 is rotatably connected to the inner wall of the lamp cover 2 through a bearing. A gear 603 is fixedly installed on the outer wall of the second rotating shaft 602. The gears 603 on the two second rotating shafts 602 mesh with each other. The left end of the second rotating shaft 602 located in the front is fixedly installed with a second motor 601, and the second motor 601 is fixedly installed on the left inner wall of the lamp cover 2. Connecting the second rotating shaft 602 to the top end of the LED lamp board 4 can drive the LED lamp board 4 to rotate when the second rotating shaft 602 rotates. And because the gears 603 on the two second rotating shafts 602 mesh, the rotation directions of the two gears 603 are opposite when the second rotating shaft 602 rotates, so that the rotation directions of the two LED lamp boards 4 are opposite, realizing the opening and closing of the LED lamp board 4;
[0024] Heat dissipation holes 10 are opened on both the left outer wall and the right outer wall of the lamp cover 2. A metal corrugated sleeve 11 is fixedly installed between the mounting plate 1 and the lamp cover 2. The metal corrugated sleeve 11 covers the angle adjustment component 5. The heat dissipation holes 10 are opened for heat dissipation, and the metal corrugated sleeve 11 is provided to shield the angle adjustment component 5, making the whole more beautiful;
[0025] A second reflector 14 is fixedly installed on the inner wall of the top of the lamp cover 2. Skirts are provided on both the front and the back of the second reflector 14, and the skirts are fixedly connected to the front inner wall and the back inner wall of the lamp cover 2. The second reflector 14 is provided to reflect more light towards the light-transmitting cover 3, so that more light can be emitted from the light-transmitting cover 3;
[0026] Threading holes are opened at the centers of the mounting plate 1 and the lamp cover 2, and a flexible wire tube 12 is inserted into the inner wall of the threading hole. Fixed rings 13 are fixedly installed at both the top end and the bottom end of the flexible wire tube 12. The fixed ring 13 at the top end is fixedly connected to the mounting plate 1, and the fixed ring 13 at the bottom end is fixedly connected to the bottom of the second reflector 14. The flexible wire tube 12 is provided for the wire to penetrate into the lamp cover 2, so as to ensure that the cylindrical LED lamp 7, the plate-shaped LED lamp 8, and the second motor 601 can receive the driving power supply. At the same time, the flexible wire tube 12 can also protect the wire and prevent the wire from being damaged by friction with the inner wall of the threading hole.
[0027] Working principle: When in use, when it is necessary to adjust the irradiation angle, turn on the first motor 502 to drive the first rotating shaft 503 to rotate, and then drive the rotating seat 504 to rotate. The rotation of the rotating seat 504 drives the lamp cover 2 to rotate, realizing the change of the orientation of the lamp cover 2, and thus adjusting the irradiation angle. When it is necessary to adjust the irradiation range, turn on the second motor 601 to drive the second rotating shaft 602 to rotate. The rotation of the second rotating shaft 602 drives the LED lamp board 4 to rotate, and at the same time drives the gear 603 to rotate. The rotation of the gear 603 drives another gear 603 to rotate, and then drives another second rotating shaft 602 to rotate. The rotation of the other second rotating shaft 602 drives another LED lamp board 4 to rotate, so that the two LED lamp boards 4 are opened or closed. When the LED lamp boards 4 are closed, only the two cylindrical LED lamps 7 can be used for irradiation, and the irradiation ranges of the two cylindrical LED lamps 7 mostly overlap. After the LED lamp boards 4 are opened, while the plate-shaped LED lamp 8 is exposed, the two cylindrical LED lamps 7 move away from each other, that is, the irradiation ranges of the two cylindrical LED lamps 7 are gradually staggered, thereby increasing the irradiation range. At the same time, the first reflector 9 is used to reflect the light of the cylindrical LED lamps 7 and the plate-shaped LED lamp 8, so that more light can be emitted from the light-transmitting cover 3.
[0028] Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
