When the lamp body 300 is flipped upward, part of the light will directly hit the human eye. At this time, the second control part 420 in the control component can be connected against the first control part 410 to form a control circuit to automatically dim the illumination brightness of the lamp body 300. When the lamp body 300 is flipped downward, the illumination direction is away from the human eye and the brightness needs to be increased. At this time, the third control part 430 in the control component can be connected against the first control part 410 to form a corresponding control circuit to automatically brighten the illumination brightness of the lamp body 300.

[0036] Reference Figure 3 to Figure 4 According to some embodiments of the present invention, the bracket 100 has a wiring channel, the first receiving groove 211 is connected to the wiring channel, the second hemispherical member 220 has a second receiving groove 221 with an opening facing upward, so that the first receiving groove 211 is connected to the second receiving groove 221, and the lamp body 300 has a wiring channel 310 inside, and the wiring channel 310 is connected to the second receiving groove 221. Specifically, the bracket 100 is generally provided with components such as a power supply and a control button, so it is necessary to lead wires from the bracket 100 to the lamp body 300, the bracket 100 has a wiring channel for wiring, the universal joint assembly 200 is connected to the end of the bracket 100, the first hemispherical member 210 can be connected to the bracket 100, the second hemispherical member 220 can be inserted into the first receiving groove 211, so that the first receiving groove 211 is connected to the second receiving groove 221, and the inner wall of the first receiving groove 211 can be set to a spherical shape, so that ... The ball part 220 can rotate universally along the inner wall of the first receiving groove 211, and the second hemispherical part 220 can be connected to the lamp body 300. The wiring channel 310 in the lamp body 300 is connected to the second receiving groove 221, and the wiring channel is connected to the first receiving groove 211. The wire can pass through the first receiving groove 211 and the second receiving groove 221 from the wiring channel of the bracket 100 to the wiring channel 310, and the hidden connection of the wires between the bracket 100 and the lamp body 300 can be achieved without affecting the universal rotation of the lamp body 300.

[0037] Reference Figure 2 and Figure 5 In some embodiments of the present invention, the first hemispherical member 210 is provided with a first wire through hole 212 and a second wire through hole 213, the second wire through hole 213 is provided on one side of the first wire through hole 212, and the first wire through hole 212 and the second wire through hole 213 are both provided on the upper part of the first hemispherical member 210, and are both connected to the first accommodating groove 211 and the wiring channel. Specifically, the first hemispherical component 210 opens downward, and the first wire through hole 212 can be set at the upper part of the first hemispherical component 210, so that the wire can be introduced into the first accommodating groove 211 from above, so that the second hemispherical component 220 is not easy to interfere with the wire when rotating, and a sufficient rotation range can be guaranteed. When there are multiple wires, the multiple wires can be passed through the first wire through hole 212 and the second wire through hole 213 respectively, so as to avoid overlapping of multiple wires to form a wire group with a larger radial size, thereby blocking the rotation of the second hemispherical component 220 and reducing the rotation range. The two wire through holes can separate the wires, thereby avoiding wire accumulation, so as to ensure the normal rotation of the universal joint assembly 200.

[0038] Reference Figure 5 In some embodiments of the present invention, the first wire through hole 212 is extended in the front-to-back direction, and there is a rounded corner between the inner wall of the first receiving groove 211 and the first wire through hole 212. Specifically, when the lamp body 300 is in use, the frequency of flipping up and down in the front-to-back direction is relatively high. By extending the first wire through hole 212 in the front-to-back direction into a long shape, the wire can be offset to a large range in the front and back at the first wire through hole 212, that is, when the second hemisphere rotates until the wire abuts, it can also push the wire to move in the extension direction of the first wire through hole 212, so that the rotation range of the second hemisphere 220 in the front-to-back direction can be expanded, and the rounded corner can prevent the wire from being squeezed by the edge during the rotation process. Through the above structure, the frequency of failure of the desk lamp can be reduced.

[0039] It can be understood that the second hemispherical member 220 is provided with a third wire through hole 222, the third wire through hole 222 is provided at the lower part of the first hemispherical member 210, and the third wire through hole 222 is connected with the second receiving groove 221 and the wiring channel 310.
