Technical Field

[0001] The invention relates to a desk lamp, and in particular to a smart and intelligently adjustable LED desk lamp. Background Art

[0002] LED desk lamps are a type of lighting equipment that uses light-emitting diodes as a light source. They are widely used in homes, offices, and learning environments.

[0003] Currently, desk lamps are roughly divided into two types: one is a desk lamp installed beside a bed for lighting, and the other is a desk lamp installed on a desk for learning lighting. The desk lamp installed beside a bed for lighting is generally large in size, and there is no way to fold it, making it inconvenient to move. The desk lamp installed on a desk for learning lighting also needs to be adjusted manually, and this type of desk lamp is small in size and light in weight, and is easily knocked over or even dropped and broken due to external force.

[0004] Therefore, there is an urgent need to develop a smart LED desk lamp that can be adjusted according to the user's own needs. Summary of the invention

[0005] In order to overcome the above-mentioned shortcomings of the prior art, the present invention provides a smart LED desk lamp that can be adjusted according to the user's own needs.

[0006] The technical solution is: a smart and intelligent LED desk lamp, including a base, a support rod, an articulated rod I, an articulated rod II, an articulated rod III and a lighting body.

[0008] Furthermore, the lighting body includes an adapter and a lampshade. The adapter is rotatably connected to the top of the hinge rod III through an axis, and the lampshade is installed at the bottom of the adapter.

[0009] Furthermore, the light bulb is contained in the lampshade, and the lampshade is composed of a fan-shaped light-blocking material and a fan-shaped light-transmitting material.

[0010] Furthermore, the lighting body also includes a connecting rod, a connecting plate and a light-blocking plate. A circle of arc-shaped holes are evenly spaced at an eccentric position at the lower part of the adapter seat. Connecting rods are slidably connected in the arc-shaped holes. The bottom end of the connecting rod is connected to the light-blocking plate. The inner side of the light-blocking plate is fitted with the outer side of the lampshade. Initially, the light-blocking plate is on the outside of the light-blocking material of the lampshade, and a connecting plate is connected between the top ends of the connecting rods.

[0028] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments.

[0029] Embodiment 1: A smart LED desk lamp, such as Figure 1-Figure 6 As shown, it includes a base 1, a support rod 2, an articulated rod I3, an articulated rod II4, an articulated rod III5, a connecting seat 6, an electric push rod 8, a control knob 81, a slider 9, a lighting body 10, a pull rod 11, a rack 12, a pinion 13, a square frame 14 and a cushion block 17. The top of the base 1 is rotatably provided with a support rod 2, the lower part of the support rod 2 is round, and the upper part is square. The top of the support rod 2 is connected to the articulated rod I3 through an axis rotation, and the articulated rod I3 can only rotate forward and reverse along the direction of the support rod 2. The top of the articulated rod I3 is connected to the articulated rod II4 through an axis rotation, and the articulated rod II4 can only rotate forward and reverse along the direction of the articulated rod I3. The top of the articulated rod II4 is connected to the articulated rod III5 through an axis rotation, and the articulated rod III5 can only rotate forward and reverse along the direction of the articulated rod II4. The bottom of the articulated rod III5 is fixedly connected to the connecting seat 6. A slide groove 7 is provided on the connecting seat 6. An electric push rod 8 is fixed on the side of the support rod 2 by bolts. The telescopic end of the top of the electric push rod 8 is rotatably connected to a slider 9. The slider 9 is slidably connected to the slide groove 7. The top of the hinged rod III5 is rotatably connected to the lighting body 10 through an axis. A pull rod 11 is slidably connected to the side of the hinged rod III5. A rack 12 is connected to the right end of the pull rod 11. Square frames 14 are provided at both front and rear ends of the axis for rotatably connecting the lighting body 10. The square frame 14 is slidably connected to the pull rod 11. A pinion 13 is provided on the axis for rotatably connecting the hinged rod III5. The pinion 13 meshes with the rack 12. A control knob 81 is provided on the base 1. The control knob 81 is linearly connected to the electric push rod 8. A pad 17 is provided at the bottom of the base 1. The height of the pad 17 can be adjusted.

[0030] like Figure 5 and Figure 6 As shown, the lighting body 10 includes an adapter 101 and a lampshade 102. The adapter 101 is connected to the top of the hinge rod III5 through an axis rotation. The lampshade 102 is installed at the bottom of the adapter 101. The lampshade 102 has a light bulb inside. The lampshade 102 is composed of a fan-shaped light-blocking material and a fan-shaped light-transmitting material.

[0031] When the desk lamp is placed beside the bed for lighting, it can be turned on directly. When the desk lamp is needed for lighting for study, the desk lamp is first placed on the desk. The pad 17 can play an anti-slip role, and the height of the pad 17 can be adjusted, so that the desk lamp can be placed more flat on the desktop. Then, the electric push rod 8 is extended by turning the control knob 81. The electric push rod 8 drives the articulated rod III5 to move upward. At the same time, the articulated rod I3, the articulated rod II4 and the articulated rod III5 in the folded state change to a vertical state. At the same time, the lighting body 10 moves upward. When the articulated rod III5 rotates upward, its rotating connected shaft also rotates clockwise, driving the gear The strip 12 moves to the right, thereby driving the pull rod 11 to move to the right, thereby driving the upper part of the square frame 14 to swing to the right, so that the adapter 101 swings to the left, driving the lampshade 102 and the light bulb therein to swing to the left for lighting. When the lampshade 102 is adjusted to the required angle, the electric push rod 8 is controlled to stop working by the control knob 81. After the table lamp is used, the electric push rod 8 is controlled to shorten by the control knob 81, driving the articulated rod Ⅰ3, the articulated rod Ⅱ4 and the articulated rod Ⅲ5 to fold downward, and the height of the lighting body 10 is reset, saving the placement space of the table lamp. After the lighting body 10 is reset, the electric push rod 8 is controlled to stop working by the control knob 81.

[0032] Embodiment 2: Based on embodiment 1, Figure 5 and Figure 6 As shown, in order to make the desk lamp more convenient to use, the lighting body 10 also includes a connecting rod 104, a connecting disk 105 and a light blocking plate 106. A circle of arc holes 103 are evenly spaced at an eccentric position at the lower part of the adapter 101. The arc holes 103 are slidably connected with the connecting rods 104. The bottom end of the connecting rod 104 is connected to the light blocking plate 106. The inner side of the light blocking plate 106 is in contact with the outer side of the lampshade 102. Initially, the light blocking plate 106 is on the outer side of the light blocking material of the lampshade 102. The connecting disk 105 is connected between the tops of the connecting rods 104. Rotating the connecting disk 105 can drive the connecting rods 104 to rotate synchronously. When performing learning lighting, In order to prevent the light transmitted through the lampshade 102 from affecting learning, the connecting disk 105 can be rotated counterclockwise at this time, and the light blocking plate 106 can be driven to rotate counterclockwise through the connecting rod 104, so that the light blocking plate 106 blocks the position of the light-transmitting material of the lampshade 102, so that the light transmitted through the lampshade 102 becomes darker, reducing the impact on the learner. At the same time, when the light blocking plate 106 blocks the position of the light-transmitting material of the lampshade 102, the light concentration in the lampshade 102 is enhanced, and the irradiated position is brighter, which can better help learners see the fonts on the book clearly. When focusing is not needed, the connecting disk 105 is reversed, and the light blocking plate 106 is driven to rotate clockwise and reset through the connecting rod 104.

[0033] like Figure 6As shown, it also includes a limit rod 107, a push rod 108 and a spiral spring 109. The push rod 108 is vertically arranged at the eccentric position on the top of the connecting plate 105. The bottom of the hinge rod III5 is fixedly connected to the limit rod 107. The end of the limit rod 107 presses on the outer side of the push rod 108, so that the push rod 108 cannot rotate. The spiral spring 109 is connected between the connecting plate 105 and the adapter 101. Figure 6 When the lampshade 102 is in the right state, the spiral spring 109 is in a deformed state; when the square frame 14 rotates to the right and drives the lampshade 102 to rotate to the left, the limiting effect of the limit rod 107 on the top rod 108 is released. At this time, under the action of the reset of the spiral spring 109, the connecting disk 105 is driven to rotate counterclockwise, and then the light blocking plate 106 is driven by the connecting rod 104 to block the position of the light-transmitting material of the lampshade 102. When the lampshade 102 is rotated to the right and reset, the limit rod 107 limits the top rod 108 from rotating to the right. At this time, under the action of gravity, the lighting body 10 is reset, and the connecting disk 105, the connecting rod 104 and the light blocking plate 106 are reset at the same time. In this way, the position of the light blocking plate 106 can be automatically adjusted, making the table lamp more convenient to use.

[0034] like Figure 7 As shown, it also includes a motor 15 and a large gear 16. The motor 15 is fixedly connected to the top of the base 1 by bolts, and the output shaft of the motor 15 is installed downward. A large gear 16 is arranged between the output shaft of the motor 15 and the bottom of the support rod 2, and the large gears 16 are meshed with each other. When it is necessary to adjust the irradiation position of the lighting body 10, the motor 15 can be controlled to rotate forward or reverse to drive the large gear 16 to rotate forward or reverse, thereby driving the support rod 2 and the device thereon to rotate forward or reverse, so that the irradiation position of the lighting body 10 is changed. After the irradiation position of the lighting body 10 is adjusted, the motor 15 is controlled to stop working.

[0035] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
