DETAILED DESCRIPTION

[0027] 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.

[0028] Embodiment: A LED desk lamp, such as Figure 1-Figure 8 As shown, it includes a base 1, which is rectangular and made of plastic material. The main function of the base 1 is to support the entire device and protect various parts in the base 1; the upper end of the base 1 is fixedly connected with an adjusting seat 2, and the adjusting seat 2 is rotatably connected with a support rod 3, which is rectangular and made of plastic material. The adjusting seat 2 is fixedly connected with a first rotating shaft 17, and the lower end of the support rod 3 is provided with a first rotating shaft hole 18, and the first rotating shaft 17 is arranged through the first rotating shaft hole 18. Both ends of the first rotating shaft 17 are threadedly connected with first nuts 11, and the support rod 3 is fixed by the threaded connection between the first nut 11 and the first rotating shaft 17.

[0029] The support rod 3 is rotatably connected to the mounting base 4, one end of the mounting base 4 is fixedly connected to the second rotating shaft 12, the upper end of the support rod 3 is provided with a second rotating shaft hole 19, the second rotating shaft 12 is arranged through the second rotating shaft hole 19, both ends of the second rotating shaft 12 are threadedly connected with second nuts 13, and the mounting base 4 is fixed by the threaded connection between the second nut 13 and the second rotating shaft 12.

[0030] When in use, loosen the first nut 11 and the second nut 13 to rotate the support rod 3 and the mounting seat 4, thereby adjusting the illumination angle of the LED desk lamp. After the adjustment is completed, re-tighten the first nut 11 and the second nut 13 to fix the support rod 3 and the mounting seat 4, thereby maintaining the adjusted illumination angle of the LED desk lamp.

[0031] Further, such as Figure 3 and Figure 4 As shown, the mounting base 4 is detachably connected to the lampshade 5, and a threaded hole 20 is opened at the other end of the mounting base 4. The upper end of the lampshade 5 is fixedly connected to the lamp housing 14, and the lamp housing 14 is threadedly connected in the threaded hole 20. An LED light source board 15 is fixedly installed in the lamp housing 14, and a driver 16 is fixedly connected to the middle part of the LED light source board 15, and the driver 16 is electrically connected to the LED light source board 15.

[0032] The driver 16 is a constant current high frequency driver 16, which can stabilize the output current and keep it constant, which is crucial to achieving optimal performance and reliability. By stabilizing the output current, the constant current high frequency driver 16 can avoid the driving current exceeding the maximum rated value of the LED, thereby improving its reliability and reducing the flicker of the LED desk lamp; at the same time, the constant current high frequency driver 16 can also ensure the consistency of the brightness and chromaticity of each LED, and effectively avoid lightning strikes, power grid surges, overcurrent, overvoltage and other protective measures, so as to extend the life of the LED.

[0033] like Figure 5-Figure 8 As shown, a battery slot 21 is provided on one side of the lower end of the base 1, and a battery is installed in the battery slot 21. The battery slot 21 is detachably connected to a battery cover 6. A cavity is provided in the base 1, and a mainboard 7 is fixedly installed in the cavity. A touch pad 8 is fixedly connected to the upper end of the base 1, and the touch pad 8 is electrically connected to the mainboard 7. When a user touches the touch pad 8, a pulse signal is generated, and this signal is received by the mainboard 7 and converted into a trigger pulse signal, thereby controlling the switch and brightness adjustment of the LED desk lamp.

[0034] Furthermore, a protective plate 9 is movably connected to the upper end of the base 1. The protective plate 9 is circular and made of plastic material. Its main function is to protect the touch pad 8. An anti-slip strip is provided on the protective plate 9 to facilitate pushing the protective plate 9. The protective plate 9 is arranged above the touch pad 8. A rotating assembly 10 is provided in the base 1. The rotating assembly 10 is used to rotate the protective plate 9, that is, after the protective plate 9 is rotated to one side of the touch pad 8, it can be reset to the touch pad 8 through the rotating assembly 10.

[0035] The rotating assembly 10 includes a connecting rod 101, one end of which is fixedly connected to one side of the protective plate 9, and the other end of the connecting rod 101 is fixedly connected to the limiting plate 102. A groove (not shown) is provided at the upper end of the base 1, and the connecting rod 101 and the limiting plate 102 are rotatably connected in the groove.

[0036] A rotating drum 103 is fixedly mounted on the inner wall of the groove of the base 1 , a spring 104 is wound around the outer wall of the connecting rod 101 , one end of the spring 104 is fixedly connected to the outer wall of the connecting rod 101 , and the other end of the spring 104 is fixedly connected to the inner wall of the rotating drum 103 .

[0037] When the protective plate 9 is rotated, the protective plate 9 will drive the connecting rod 101 to rotate to overcome the elastic force of the spring 104. When the protective plate 9 is released, the connecting plate will rotate due to the rebound force of the spring 104, thereby causing the protective plate 9 to rotate. The protective plate 9 rotates back to the touch pad 8 to protect the touch pad 8 again.

[0038] A coaxial slideway (not shown) is provided in the groove of the base 1 , and a slider 105 is slidably connected in the slideway. The slider 105 is fixedly connected to one side of the limiting plate 102 , and the slider 105 is used to limit the rotation of the limiting plate 102 .

[0039] When the connecting rod 101 rotates, the limit plate 102 will rotate accordingly, thereby driving the slider 105 to slide in the slide of the base 1, and the slide is arc-shaped, so that when the slider 105 slides to the edge of one end of the slide, it abuts the edge of the slide and cannot continue to slide. When the protective plate 9 rotates to the top of the touch pad 8, the slider 105 just slides to the edge of the other end of the slide, abuts the edge of the slide and cannot continue to slide, so that the protective plate 9 will not fall off the top of the touch pad 8.

[0040] By setting a protective plate 9 above the touch pad 8, the protective plate 9 can protect the touch pad 8 when the touch pad 8 is not in use. When the touch pad 8 is used, it is only necessary to push the protective plate 9 and turn the protective plate 9 to one side of the touch pad 8, and then touch the touch pad 8. After releasing the protective plate 9, the clockwork spring 104 in the rotating drum 103 rebounds and drives the connecting rod 101 to rotate, thereby causing the protective plate 9 to rotate. At the same time, the slider 105 will limit the rotation of the protective plate 9, so that the protective plate 9 is just above the touch pad 8, and the touch pad 8 is protected again.

[0041] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
