Description

Technical Field

[0001] The present invention relates to the technical field related to lighting appliances, and in particular to an energy-saving intelligent anti-myopia desk lamp and a use method thereof. Background Art

[0002] The primary function of a desk lamp is illumination, making it particularly suitable for reading, studying, and working. Not only does it provide localized illumination, but it also adjusts the brightness and color temperature to enhance work efficiency or creative quality. Furthermore, desk lamps also serve as decorative elements in the home, adding a unique charm to any space.

[0003] Most existing desk lamps have independent height and brightness adjustment functions, making it difficult to automatically adjust the brightness when adjusting the height. After adjusting the height of the desk lamp to suit the user's needs, the user often needs to manually adjust the brightness again to achieve the desired lighting effect. This operation is not only cumbersome, but if the user fails to adjust the brightness promptly and accurately, the inappropriate brightness at different heights may cause eye damage and increase the risk of myopia. For example, if the brightness of the desk lamp is not increased accordingly when it is raised, the desktop may appear dim. Long-term reading and working in this environment can easily lead to eye fatigue and myopia. Conversely, if the brightness of the desk lamp is not reduced when it is lowered, the excessive light may cause glare, which can also have adverse effects on the eyes. Summary of the Invention

It is simple to operate, easy to use, and has a wide range of applications.

[0023] 2. This energy-saving intelligent anti-myopia desk lamp and its usage method are configured by setting a regulating component. When the exposed length of the regulating rod outside the support rod is adjusted by the regulating component, the regulating rod moves upward, and the cable pulls the driving sleeve to move horizontally toward the side close to the regulating rod. When the regulating rod moves downward, the cable pulls the driving sleeve to move horizontally away from the regulating rod. The movement of the driving sleeve drives the driving rod to follow the movement. The movement of the driving rod cooperates with the driving groove to drive the driving shaft to rotate. The rotation of the driving shaft drives the bevel gear sleeve to rotate through the bevel gear, and drives the ring sleeve to rotate through the connecting rod. The rotation of the ring sleeve can adjust the area of the light-transmitting channel through the adjusting unit. By adjusting the area of the light-transmitting channel, the light emitted by the lamp panel is made more concentrated or more dispersed, so as to adjust the brightness of the desktop, thereby linking the height adjustment and the illumination brightness adjustment together. The operation is simple and easy to use.

[0024] 3. This energy-saving intelligent anti-myopia desk lamp and its usage method, by setting a control component, the ring sleeve rotates through the arc-shaped gear ring to drive several column gears and the rotating shaft to rotate, the column gear rotates to drive the rack and the trapezoidal adjustment plate to move, and the several trapezoidal adjustment plates move synchronously and can adaptively adjust the area of the light-transmitting channel, that is, when the adjustment rod drives the lamp board to move upward, it will reduce the area of the light-transmitting channel and increase the reflection area of the trapezoidal adjustment plate, so that the light emitted by the lamp board is reflected by the reflective coating, and more reflections are concentrated in the range illuminated by the light-transmitting channel, making the light more concentrated and directional, thereby improving the brightness of the desktop illumination area; when the adjustment rod drives the lamp board to move downward, it will increase the area of the light-transmitting channel and reduce the reflection area of the trapezoidal adjustment plate, so that the light passing through the light-transmitting channel is more dispersed, avoiding the light being more concentrated due to the distance between the lamp board and the desktop being too close, making the brightness of the illumination area strong and interfering with the user's vision, always providing the user with appropriate lighting brightness and lighting range, avoiding eye fatigue caused by uncomfortable brightness, effectively preventing myopia, and protecting the user's vision health.

[0025] 4. This energy-saving intelligent anti-myopia desk lamp and its usage method, by setting a number of trapezoidal adjustment pieces, can make the trapezoidal adjustment pieces adjust the area of the light-transmitting channel in an infinite manner during the process of adjusting the area of the light-transmitting channel, so that the user can obtain appropriate brightness, with a wide range of applications and strong practicality.

[0042] Specifically, during the use of the desk lamp, the height of the lamp panel 10 can be adaptively adjusted through the adjustment component 12 according to the user's own situation and actual use needs. When the adjustment component 12 adjusts the height of the adjustment rod 3, the driving unit 91 will drive the adjustment unit 92 to adaptively adjust the area of the light-transmitting channel to adjust the brightness of the desktop. By adaptively adjusting the brightness when adjusting the height, the user is always provided with appropriate lighting brightness, avoiding eye fatigue caused by uncomfortable brightness, effectively preventing myopia, and protecting the user's vision health.

[0043] Further, such as Figure 4 、 Figure 5 、 Figure 7 、 Figure 8 and Figure 9 As shown, the regulating assembly 9 includes a driving unit 91 arranged in the crossbeam 4 and a plurality of regulating units 92 arranged on the fixing ring 11. One end of the cable 7 extends into the support rod 2 and is fixedly connected to the support rod 2. The bottom of the regulating rod 3 is provided with a channel for the cable 7 to pass through. The driving unit 91 includes a ring sleeve 911 rotatably mounted in the cylindrical portion 51. A driving shaft 912 is rotatably mounted in the crossbeam 4, and a driving groove 913 is provided on the outer surface of the driving shaft 912, and the driving groove 913 is a spiral structure. A driving sleeve 914 is slidingly mounted in the crossbeam 4. The driving sleeve 914 A driving rod 915 is fixedly installed inside for use with the driving groove 913. The other end of the cable 7 is fixedly connected to the driving sleeve 914. One end of the driving shaft 912 extends into the cylindrical portion 51 and is fixedly installed with a bevel gear 916. A bevel gear sleeve 917 that meshes with the bevel gear 916 is rotatably installed on the mounting column 8. Several connecting rods 918 are fixedly installed on the ring sleeve 911. The top ends of the several connecting rods 918 are fixedly connected to the bevel gear sleeve 917. A mounting ring 919 is fixedly installed inside the crossbeam 4. A spring 9110 is fixedly installed between the mounting ring 919 and the driving sleeve 914.

[0044] Specifically, when the exposed length of the adjusting rod 3 outside the support rod 2 is adjusted by the adjusting assembly 12, the adjusting rod 3 moves upward, and the cable 7 will pull the drive sleeve 914 to move horizontally toward the side close to the adjusting rod 3; when the adjusting rod 3 moves downward, the cable 7 will pull the drive sleeve 914 to move horizontally away from the side of the adjusting rod 3, and the movement of the drive sleeve 914 drives the drive rod 915 to follow the movement, and the movement of the drive rod 915 cooperates with the drive groove 913 to drive the drive shaft 912 to rotate, and the rotation of the drive shaft 912 drives the bevel gear sleeve 916 through the bevel gear 17 rotates, and drives the ring sleeve 911 to rotate through the connecting rod 918. The rotation of the ring sleeve 911 can adjust the area of the light-transmitting channel through the adjustment unit 92. By adjusting the area of the light-transmitting channel, the light emitted by the lamp board 10 is made more concentrated or more dispersed, so as to adjust the brightness of the desktop, thereby linking the height adjustment and the illumination brightness adjustment together. The operation is simple and easy to use. By setting the spring 9110, the cable 7 can be kept in a taut state, so that the cable 7 can respond quickly during the movement of the adjustment rod 3.

[0045] Further, such as Figure 5 、 Figure 8 and Figure 9 As shown, a plurality of guide blocks 9111 are fixedly installed on the outer surface of the driving sleeve 914, and a plurality of guide grooves 9112 for cooperating with the guide blocks 9111 are opened in the crossbeam 4. By cooperating with the guide blocks 9111 and the guide grooves 9112, the stability of the driving sleeve 914 during movement can be ensured.

[0046] Among them, such as Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 10 As shown, the number of adjustment units 92 is no less than six, and the adjustment unit 92 includes a rotating shaft 921 rotatably mounted on the fixed ring 11, a column gear 922 fixedly mounted on the rotating shaft 921, an arc-shaped gear ring 923 fixedly mounted on the ring sleeve 911 and meshing with the column gear 922 on the same side, and a trapezoidal adjustment piece 924 slidably mounted on the fixed ring 11, one waist of the trapezoidal adjustment piece 924 is fixedly mounted with a rack 925 meshing with the column gear 922 on the same side, a trapezoidal groove 926 is provided on the trapezoidal adjustment piece 924, a trapezoidal guide column 927 used in conjunction with the trapezoidal groove 926 is fixedly mounted on the fixed ring 11, the trapezoidal guide column 927 fits and slides in the trapezoidal groove 926 on the same side, and the inner side surface of the cylindrical portion 51, the inner side surface of the conical portion 52 and the upper surface of the trapezoidal adjustment piece 924 are all provided with a reflective coating.

[0047] Specifically, the ring sleeve 911 rotates through the arc-shaped gear ring 923 to drive several column gears 922 and the rotating shaft 921 to rotate. The rotation of the column gear 922 drives the rack 925 and the trapezoidal adjustment piece 924 to move, so that the trapezoidal adjustment piece 924 slides close to the adjacent trapezoidal adjustment piece 924. Several trapezoidal adjustment pieces 924 move synchronously and can adaptively adjust the area of the light-transmitting channel. Specifically, when the adjustment rod 3 drives the lamp board 10 to move upward, the cable 7 will pull the drive sleeve 914 horizontally to the side close to the adjustment rod 3, so that the drive shaft 912 rotates forward, thereby driving several trapezoidal adjustment pieces 924 to move closer to each other, reducing the area of the light-transmitting channel while increasing the reflection area of the trapezoidal adjustment piece 924, so that the light emitted by the lamp board 10 is reflected by the reflective coating, and more reflections are concentrated in the range illuminated by the light-transmitting channel, making the light more concentrated and directional. To improve the brightness of the desktop illumination area, so as to avoid the situation where the brightness does not increase accordingly after the lamp board 10 is raised, the desktop may appear dim, and long-term reading and working in such an environment will easily cause eye fatigue, which in turn causes myopia; when the adjustment rod 3 drives the lamp board 10 to move downward, the cable 7 will pull the drive sleeve 914 horizontally to the side away from the adjustment rod 3, causing the drive shaft 912 to reverse, thereby driving several trapezoidal adjustment pieces 924 away from each other, increasing the area of the light-transmitting channel while reducing the reflection area of the trapezoidal adjustment piece 924, making the light passing through the light-transmitting channel more dispersed, avoiding the light being more concentrated due to the lamp board 10 being too close to the desktop, making the brightness of the illumination area stronger and causing interference to the user's vision, always providing users with appropriate lighting brightness and lighting range, avoiding eye fatigue caused by inappropriate brightness, effectively preventing myopia, and protecting the user's vision health.

[0048] Among them, such as Figure 5 、 Figure 6 and Figure 7 As shown, several trapezoidal adjustment pieces 924 are evenly distributed in an array along the circumference of the fixed ring 11, and two adjacent trapezoidal adjustment pieces 924 are slidingly fitted together. The shape of the trapezoidal adjustment piece 924 is an isosceles trapezoid, which allows the trapezoidal adjustment piece 924 to infinitely adjust the area of the light-transmitting channel during the process of adjusting the area of the light-transmitting channel, so that the user can obtain appropriate brightness, with a wide range of applications and strong practicality.

[0049] Among them, such as Figure 1 、 Figure 2 and Figure 3 As shown, the adjustment assembly 12 includes a threaded rod 121 rotatably mounted in the support rod 2, a sleeve 122 is threadedly mounted on the top end of the threaded rod 121, and the top end of the sleeve 122 is fixedly connected to the adjustment rod 3, a worm gear 123 is fixedly mounted on the threaded rod 121, and a worm 124 meshing with the worm gear 123 is rotatably mounted on the support rod 2, and one end of the worm 124 extends to the outside of the support rod 2 and is fixedly mounted with a handwheel.

[0050] Specifically, rotating the handwheel drives the worm 124 to rotate, the rotation of the worm 124 drives the worm wheel 123 and the threaded rod 121 to rotate, the rotation of the threaded rod 121 drives the sleeve 122 and the adjusting rod 3 to move, and the movement of the adjusting rod 3 drives the lamp board 10 to follow the movement, so that the height of the desk lamp can be adaptively adjusted according to the user's own height and actual usage needs. It is simple to operate, easy to use, and has a wide range of applications.

[0051] Among them, such as Figure 2 and Figure 3 As shown, the adjusting rod 3 is fixedly installed with no less than two inserting strips 125, and the support rod 2 is provided with a slot 126 for cooperating with the inserting strip 125. Through the cooperation of the inserting strip 125 and the slot 126, the movement of the adjusting rod 3 can be guided and limited to prevent the adjusting rod 3 from rotating during the movement, thereby ensuring the stability of the adjusting rod 3 when moving up and down.

[0052] Among them, such as Figure 4 As shown, a damping pad 14 is provided at the rotational connection between the beam 4 and the lampshade 5, which is used to increase the friction force of rotation between the lampshade 5 and the beam 4. By providing the damping pad 14, it is convenient to adjust the angle of the lampshade 5, so that the illumination angle of the lamp panel 10 can be adaptively adjusted as needed.

[0053] A method for using an energy-saving intelligent anti-myopia desk lamp comprises the following steps:

[0054] S1, installation, place the support rod 2 on the table through the base 1;

[0055] S2. Adjust the height of the adjusting rod 3 by turning the hand wheel to rotate the worm 124. The rotation of the worm 124 drives the worm wheel 123 and the threaded rod 121 to rotate. The threaded rod 121 rotates to match the slot 126 and the insert 125 to drive the sleeve 122 to move upward. The movement of the sleeve 122 drives the adjusting rod 3 to follow the movement, and the adjusting rod 3 is adjusted to the appropriate height;

[0056] S3, while the adjusting rod 3 moves upward, the cable 7 will pull the driving sleeve 914 to move horizontally to one side of the adjusting rod 3. The movement of the driving sleeve 914 drives the driving rod 915 to follow the movement. The movement of the driving rod 915 cooperates with the driving slot 913 to drive the driving shaft 912 to rotate. The rotation of the driving shaft 912 drives the bevel gear sleeve 917 to rotate through the bevel gear 916, and drives the ring sleeve 911 to rotate through the connecting rod 918. The rotation of the ring sleeve 911 drives several column gears 922 and the rotating shaft 921 to rotate through the arc-shaped gear ring 923. The column gear 922 rotates and drives the rack 925 and the trapezoidal adjusting piece 924 to move. Several trapezoidal adjusting pieces 924 move synchronously and adjust the area of the light-transmitting channel to adjust the brightness of the desktop. Through the adaptive adjustment of height and brightness, the user is always provided with appropriate lighting brightness, avoiding eye fatigue caused by brightness discomfort, effectively preventing myopia, and protecting the user's vision health.

[0057] During operation, the height of the adjusting rod 3 and the light board 10 is adjusted according to the actual needs of the user. The hand wheel is turned to rotate the worm 124, and the rotation of the worm 124 drives the worm wheel 123 and the threaded rod 121 to rotate. The rotation of the threaded rod 121 drives the sleeve 122 and the adjusting rod 3 to move. The movement of the adjusting rod 3 drives the light board 10 to follow the movement.

[0058] When the adjusting rod 3 moves, the driving sleeve 914 will follow the movement through the cable 7, and the driving sleeve 914 will drive the driving rod 915 to follow the movement. The driving rod 915 will move in conjunction with the driving groove 913 to drive the driving shaft 912 to rotate. The driving shaft 912 rotates through the bevel gear 916 to drive the bevel gear sleeve 917 to rotate, and drives the ring sleeve 911 to rotate through the connecting rod 918. The ring sleeve 911 rotates through the arc gear ring 923 to drive several column gears 922 and the rotating shaft 921 to rotate. The column gear 922 rotates and drives the rack 92 5 and the trapezoidal adjusting piece 924 move, so that the trapezoidal adjusting piece 924 slides close to the adjacent trapezoidal adjusting piece 924, and several trapezoidal adjusting pieces 924 move synchronously and can adaptively adjust the area of the light transmission channel. Specifically, when the adjusting rod 3 drives the light board 10 to move upward, the cable 7 pulls the driving sleeve 914 horizontally to move toward the side close to the adjusting rod 3, so that the driving shaft 912 rotates forward, thereby driving several trapezoidal adjusting pieces 924 to move closer to each other, reducing the area of the light transmission channel while increasing the trapezoidal adjusting piece 9 The reflective area of 24 makes the light emitted by the lamp board 10 reflect through the reflective coating, and more reflections are concentrated in the range of the light-transmitting channel, making the light more concentrated and directional, thereby improving the brightness of the desktop illumination area, thereby avoiding that when the lamp board 10 is turned up, the brightness does not increase accordingly, and the desktop may appear dim. Reading and working in such an environment for a long time will easily cause eye fatigue, which will lead to myopia; when the adjustment rod 3 drives the lamp board 10 to move downward, the cable 7 will pull the drive sleeve 914 horizontally to the side away from the adjustment rod 3, causing the drive shaft 912 to reverse, thereby driving several trapezoidal adjustment pieces 924 away from each other, increasing the area of the light-transmitting channel while reducing the reflective area of the trapezoidal adjustment pieces 924, making the light passing through the light-transmitting channel more dispersed, avoiding the light being more concentrated due to the lamp board 10 being too close to the desktop, making the brightness of the illumination area strong and interfering with the user's vision, always providing users with appropriate lighting brightness and lighting range, avoiding eye fatigue caused by inappropriate brightness, effectively preventing myopia, and protecting the user's vision health.
