In this embodiment, the desk lamp base 100 is roughly disc-shaped, the desk lamp connecting rod 200 is arranged on the front side of the desk lamp base 100, and the lower end of the desk lamp connecting rod 200 is connected to the front side of the desk lamp base 100. The lamp panel 300 is flat, the lamp panel 300 is arranged on the front side of the desk lamp connecting rod 200, and the lamp panel 300 is connected to the upper end of the desk lamp connecting rod 200, and a plurality of light sources 310 that can emit light when powered on are arranged at intervals on the lower surface of the lamp panel 300. In this embodiment, all the light sources 310 are LED light-emitting chips that can emit light when powered on. The control circuit is arranged on the lamp panel 300 or the lamp base 100, and the control circuit is connected to the circuits of all the light sources 310. The control circuit can adjust the brightness of each light source 310 when it is powered on, and / or the control circuit can control whether each light source 310 is powered on to emit light. The detection device 400 is arranged on the lower surface of the lamp panel 300, and the detection device 400 is electrically connected to the control circuit; when the light source 310 is powered on to emit light, the detection device 400 can detect the position of the user's hand movement in real time and feed back the detection result to the control circuit. According to the detection result fed back by the detection device 400, the control circuit can control and adjust the brightness of all the light sources 310 and make the brightness of the light irradiated to the surrounding environment of the user's hand consistent.

[0030] The shadowless eye-protection desk lamp of this embodiment is provided with a plurality of light sources 310 that can emit light when powered on, at intervals, on the lower surface of the lamp panel 300. At the same time, a detection device 400 that can detect the position of the user's hand movement in real time is provided on the lower surface of the lamp panel 300. When the shadowless eye-protection desk lamp of this embodiment is used for lighting, all the light sources 310 on the lower surface of the lamp panel 300 are powered on and emit light downward. At this time, a shadowless area is formed in the lighting area of ​​the shadowless eye-protection desk lamp. When the user's hand holds the pen and moves back and forth in the lighting area to write, the detection device 400 detects the position of the user's hand movement in real time and feeds back the detection result to the control circuit. The control circuit controls and adjusts the brightness of all the light sources 310 according to the detection result fed back by the detection device 400, so that the brightness of the light irradiated to the environment around the user's hand is consistent, thereby effectively preventing the formation of glare, and thus helping to protect the user's eyesight.

[0031] It should be noted that, in the above embodiments, the control circuit adjusts the brightness of each light source 310 when it is powered on, and / or the control circuit can control whether each light source 310 is powered on to emit light, so that the brightness of the light irradiated by the desk lamp to the surrounding environment of the user's hand is consistent. In certain embodiments of the present invention, the control circuit can also adopt other control methods, such as dividing the multiple light sources 310 arranged on the lower surface of the lamp panel 300 into multiple areas, and the control circuit is electrically connected to the light sources 310 in all areas. When the detection device 400 detects the position of the user's hand movement in real time and feeds back the detection results to the control circuit, the control circuit can adjust the brightness of the light emitted by the light sources 310 in different areas, so that the brightness of the light irradiated to the surrounding environment of the user's hand is consistent, thereby preventing the formation of glare.

[0032] It can be understood that in the above embodiment, the table lamp base 100 is roughly disc-shaped, while in other embodiments of the present invention, the shape of the table lamp base 100 can also be set to a rectangular or elliptical or hexagonal shape or other irregular shapes, and is not limited to the above-mentioned disc shape, and can be determined according to actual needs.

[0033] In order to facilitate the production and processing of the desk lamp connecting rod 200, in certain embodiments of the present invention, the desk lamp connecting rod 200 is a bar-shaped rod with a rectangular cross section. By setting the desk lamp connecting rod 200 to a bar-shaped rod with a rectangular cross section, it is convenient for enterprises to produce and process the desk lamp connecting rod 200, which helps to reduce the production cost of the shadowless eye protection desk lamp of this embodiment and increase the social competitiveness of the enterprise. It is understandable that in addition to being set to the above-mentioned shape, the desk lamp connecting rod 200 can also be set to other shapes, such as the desk lamp connecting rod 200 is a cylindrical rod, or the desk lamp connecting rod 200 is a rod with an elliptical or polygonal cross section or other irregular shapes, which can be determined according to actual needs.

[0034] Reference Figure 2 , Figure 3 and Figure 4 In order to make the lighting area of ​​the shadowless eye protection desk lamp wider, in some embodiments of the present invention, the lamp panel 300 is circular. Specifically, the lamp panel 300 is a circular plate, and all the light sources 310 are arranged on the lower surface of the lamp panel 300 at intervals along the circumference of the lamp panel 300. Specifically, all the light sources 310 are arranged on the lower surface of the lamp panel 300, and all the light sources 310 are arranged into a plurality of light source ring components, all the light source ring components are arranged coaxially with the lamp panel 300, and all the light source ring components are arranged in sequence from the center of the lamp panel 300 to the outer periphery of the lamp panel 300 at intervals, that is, all the light source ring components are gradually arranged from the center of the lamp panel 300 to the outer periphery of the lamp panel 300. By adopting the above structure, the area of ​​the lighting area of ​​the shadowless eye protection desk lamp of this embodiment can be increased, and the brightness of each position of the lighting area of ​​the shadowless eye protection desk lamp can be made more uniform.

[0035] In certain embodiments of the present invention, a plurality of groups of light source ring assemblies are evenly arranged in sequence on the upper surface of the lamp panel 300 in a direction from the center of the lamp panel 300 toward the outer periphery of the lamp panel 300. Each group of light source ring assemblies contains the same number of light sources 310, that is, the number of light sources 310 arranged to constitute each group of light source ring assemblies is the same. In one group of light source ring assemblies, all the light sources 310 are evenly arranged at circumferential intervals around the lamp panel 300. By adopting the above-mentioned structure, when the shadowless eye protection desk lamp of this embodiment is powered on, the shadowless eye protection desk lamp can emit light more evenly, can avoid the formation of glare as much as possible, and helps to protect the user's eyes and vision.

[0036] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 In order to enable the detection device 400 to better detect the movement of the user's hand in the lighting area, in some embodiments of the present invention, the detection device 400 is arranged at the center of the lower surface of the lamp panel 300. By arranging the detection device 400 at the center of the lower surface of the lamp panel 300, when all the light sources 310 on the lower surface of the lamp panel 300 are powered on to emit light downward and form a lighting area, the detection device 400 is just located at the center of the lighting area, so the detection device 400 can better monitor the user's hand moving up, down, left and right in the lighting area, so the detection device 400 can more accurately detect the position of the user's hand moving in the lighting area and feed back the detection results to the control circuit, and the control circuit can adjust and control the luminous brightness of different light sources 310, so as to keep the light brightness of the environment around the user's hand consistent, achieve a shadowless effect, and at the same time prevent the formation of glare, which helps to protect the user's eyes.

[0037] In order to reduce the production cost of the shadowless eye protection desk lamp, in some embodiments of the present invention, the detection device 400 is a camera. Since the use of a camera to monitor the movement of an object is a well-known technique in the art, it will not be described in detail here. The shadowless eye protection desk lamp of this embodiment uses a camera as the detection device 400, which can make the real-time detection or monitoring of the position of the user's hand movement by the detection device 400 more accurate and reliable, and the camera can be purchased on the market, and the cost of the camera is low, which helps to reduce the production cost of the shadowless eye protection desk lamp.

[0038] It should be noted that in the above embodiment, the detection device 400 is a camera, and in some embodiments of the present invention, the detection device 400 can also be set to other structures, such as the detection device 400 is a plurality of infrared detection sensors, in which case the lower surface of the lamp panel 300 can be evenly spaced to set a plurality of infrared detection sensors, and all infrared detection sensors are electrically connected to the control circuit. When the shadowless eye protection desk lamp of this embodiment is used for lighting, all light sources 310 are powered on and emit light downward to form a lighting area, and at this time, the plurality of infrared detection sensors are also powered on and emit light and send multiple infrared rays to the lighting area. When the user's hand moves up, down, left, and right in the lighting area, the user's hand will block and reflect the infrared rays to the infrared detection sensor for reception. The control circuit can calculate the position of the user's hand in the lighting area by calculating the time and sequence of the reflected infrared rays received by the plurality of infrared detection sensors, thereby being able to achieve real-time monitoring or detection of the position of the user's hand moving in the lighting area.

[0039] It is understandable that in the above embodiment, the detection device 400 is a plurality of infrared detection sensors, and in certain embodiments of the present invention, the detection device 400 can also be set to other structures, such as the detection device 400 includes a plurality of ultrasonic detection sensors, and the plurality of ultrasonic detection sensors are evenly spaced and arranged on the lower surface of the lamp panel 300, and all ultrasonic detection sensors are electrically connected to the control circuit. When the shadowless eye protection desk lamp of this embodiment is used for lighting, all light sources 310 are powered on and emit light downward to form a lighting area. When the user's hand moves up, down, left, and right in the lighting area, the plurality of ultrasonic detection sensors synchronously emit ultrasonic waves to the lighting area. The user's hand will block and reflect the ultrasonic wave to the ultrasonic detection sensor during the movement. The control circuit can calculate the time and order of receiving the reflected ultrasonic wave by the plurality of ultrasonic detection sensors, that is, the position of the user's hand in the lighting area can be calculated, so that real-time monitoring or detection of the position of the user's hand moving in the lighting area can be achieved.

[0040] Reference Figure 2 and Figure 3In order to prevent the light source 310 from emitting light in the horizontal direction, in some embodiments of the present invention, a groove 301 is provided on the lower surface of the lamp panel 300, which is sunken into the interior of the lamp panel 300, and all the light sources 310 are arranged on the bottom wall of the groove 301. By adopting the above structure, the side wall of the groove 301 can block the light emitted in the horizontal direction when the light source 310 is powered on, thereby preventing the light from directly entering the user's eyes, which helps to prevent the formation of glare.

[0041] In some embodiments of the present invention, a connecting arm 320 is provided on one side of the lamp panel 300, and one end of the connecting arm 320 away from the lamp panel 300 is rotatably connected to the upper end of the table lamp connecting rod 200, and a second locking device is provided between the connecting arm 320 and the table lamp connecting rod 200. Specifically, the second locking device includes a second bolt 420 and a second nut. An upper mounting hole is provided on the upper end of the table lamp connecting rod 200, and a connecting mounting hole 321 is provided on one end of the connecting arm 320 away from the lamp panel 300. When the lamp panel 300 and the table lamp connecting rod 200 are connected, the second bolt 420 is inserted into the upper mounting hole and the connecting mounting hole, so that the second bolt 420 rotatably connects the lamp panel 300 and the table lamp connecting rod 200 together, and the second nut is threadedly connected to the outer peripheral wall of the second bolt 420. When the user needs to adjust the rotation of the lamp panel 300 relative to the desk lamp connecting rod 200, the user can loosen the second nut. At this time, the lamp panel 300 can rotate relative to the desk lamp connecting rod 200 around the second bolt 420. When the lamp panel 300 is rotated to a suitable angle or position, the user can tighten the second nut to lock the position of the lamp panel 300 and the desk lamp connecting rod 200 to prevent the lamp panel 300 from rotating at will during subsequent use and affecting the light emission direction of the light source 310.

[0042] In some embodiments of the present invention, the lower end of the table lamp connecting rod 200 is rotatably connected to the table lamp base 100, and a first locking device is provided between the table lamp base 100 and the lower end of the table lamp connecting rod 200. Specifically, the first locking device includes a first bolt 410 and a first nut. The lower end of the table lamp connecting rod 200 is provided with a lower connecting hole, and the table lamp base 100 is provided with a base connecting hole. When the table lamp connecting rod 200 and the table lamp base 100 are connected, the first bolt 410 is inserted into the lower connecting hole and the base connecting hole, and the first nut is threadedly connected to the outer peripheral wall of the first bolt 410. When the user adjusts the table lamp connecting rod 200 to swing relative to the table lamp base 100, the user can loosen the first nut. At this time, the user can drive the table lamp connecting rod 200 to swing relative to the table lamp base 100 to a set angle or position, and then the user tightens the first nut, thereby locking the relative position of the table lamp connecting rod 200 and the table lamp base 100, which is convenient for the subsequent use of the shadowless eye protection table lamp.

[0043] In order to facilitate the user to turn on or off the shadowless eye protection desk lamp, in some embodiments of the present invention, a switch 110 electrically connected to the control circuit is provided on the upper surface of the desk lamp base 100. The user switch 110 can quickly control the light source 310 to be powered on or off, which is convenient for the use of the shadowless eye protection desk lamp.
