Referring to FIG. 39 together, the desk lamp further includes a wiring structure including a first wire connecting the first lamp cap 50 and a second wire connecting the second lamp cap 70. The first wire and the second wire are both worn. The head of the over-rotating head is electrically connected to the second control module (ie, the aforementioned control module) for supplying power to the first base 50 and the second base 70. The first trace passes through the trench 815, and the second trace passes through the via hole 816, and the threaded via 816 is adjacent to the trench 815. The wiring structure further includes a wire connected to the second control module, and the wire enters the base 10 through the touch segment 23 and the support segment.

Specifically, the first wire passes through the through slot 315 and the rotating head of the connecting portion 35 of the bracket 30. The groove 815 of the 81 and the inside of the buckle tube 21 of the lamp post 20 are electrically connected to the circuit board 27 in the buckle tube 21. The second trace passes through the through slot 335 of the connecting portion 35 of the bracket 30, the threading hole 816 of the rotating head 81, the inside of the buckle tube 21 of the lamp post 20, and is electrically connected to the circuit board 27 in the buckle tube. Thereafter, the wire protrudes from the circuit board, passes through the through hole 237 of the transparent tube 231 and the channel 2502 of the buckle 25, and then enters the inside of the bottom case 11 and the first circuit board 151 of the circuit board 15 from the center hole 923 of the fixing member. And the second circuit board 152 is electrically connected.

The threading hole 816 is adjacent to the trench 815 and separated from the trench 815. The wires of the first lamp cap 50 and the second lamp cap 70 are respectively passed through the separated groove 815 and the threading hole 816 without passing through the groove 815 at the same time. First, the first lamp cap 50 and the second lamp are connected. The number of wires of the lamp cap 70 is very large. If they are mixed together through the groove 815, it is difficult to distinguish which one is connected to the first lamp cap 50 and which is connected to the second lamp cap 70 at the time of later cable management, which is liable to cause confusion. Therefore, the wire connecting the first lamp cap 50 is inserted into the groove 815, and the wire connecting the second lamp cap 70 is inserted into the threading hole 816 to avoid confusion.

Secondly, the groove 815 also has the function of threading the plunger 86, and the plunger 86 moves left and right in the groove 815. If the wire connecting the second lamp head 70 also passes through the groove 815, the second lamp head 70 is located. The left side of the trench 815, then the wire connecting the second lamp head 70 will also pass through the left side of the trench. However, since the space reserved for the left side of the groove 815 is small, if the wire connecting the second lamp head 70 passes through the groove 815, the plunger 86 will press against the second lamp head 70 when moving to the left. Wires can cause wire damage after repeated pressures for a long time.

Third, if the left side of the groove 815 is elongated, the space reserved on the left side of the groove 815 is made larger, so that the plunger 86 is prevented from being pressed against the wire connecting the second lamp head 70 when it is moving. However, the consequence of this is that when the first base 50 is rotated downward, the left side of the groove is too long to be blocked by the bracket 30 and exposed to the outside, thereby affecting the appearance of the lighting device. Moreover, the exposed left side of the groove 815 is also easy to enter impurities such as dust and water vapor, which affects the use of the lighting device.

Referring to FIG. 23, specifically, the first circuit board 531 of the first lamp cap 50 is provided with the first control module to control a plurality of LED lights. The light source and switch 562 are connected to the first control module by wires. The first control module may operate separately after the first base 50 is removed, or may cooperate with the second control module on the circuit board 27 within the light pole 20 after the first base 50 is inserted.

After the first base 50 is inserted, the first control module is electrically coupled to the connector 36 in the bracket 30 via the interface 552 of the first base 50. The joint 36 of the bracket 30 and the second control module in the lamp post pass the aforementioned The wires connecting the first caps 50 are electrically connected. The circuit board of the LED module 72 in the second lamp head 70 and the second control module in the lamp post 20 are electrically connected by the aforementioned wires connecting the second lamp heads 70.

The circuit board 27 housed in the buckle tube 21 of the lamp post 20 is a control circuit board, and the second control module is disposed on the circuit board 27. The wires connecting the first lamp cap 50 and the second lamp cap 70 are connected to the circuit board 27 through the opening of the top of the buckle tube 21, and the circuit board 27 is also electrically connected to the flexible touch panel 230 wrapped on the outside of the transparent tube 231 through the flexible circuit board. connection.

After the first cap 50 is inserted, the battery in the first cap 50 supplies power to the second control module of the stem 20 and the flexible touchpad 232 and the second cap 70. Of course, it is also possible to insert an external power source on the input interface 16 of the base 10 for power supply.

When the interface of the first base 50 is inserted into the bracket 30, the second control module is electrically connected to the first control module. The second control module is configured to control the brightness of the first base 50 and the second base 70 according to the touch gesture sensed by the flexible touch panel. For example, when the single finger slides from the top, the brightness of the first lamp head 50 is lowered. When the brightness of the first lamp head 50 is turned off, the second lamp head 70 is automatically turned on. When the single finger slides from bottom to top again, the second base 70 is extinguished and the first base 50 is gradually brightened. For example, the downward sliding of the two fingers is to adjust the color temperature of the first lamp cap 50.

The second control module is a central control module of the lighting device, which is placed in the light pole 20 to save overall volume, so as to avoid occupying the space inside the base 10 and affecting the placement of the circuit board 15. The second control module is disposed in an upper region of the light pole 20 (ie, above the flexible touch panel) because the number of wires extending from the second base 70 and the first base 50 into the pole is very large, if the second control module is located at the lamp The lower portion of the rod 20 (i.e., below the flexible touch panel), then these wires must pass a long distance to be connected to the circuit board 27. Such a long wire can cause the first base 50 to be easily entangled or even broken when rotated.

The above is a preferred embodiment of the present invention, and it should be noted that those skilled in the art can also make several improvements and retouchings without departing from the principles of the present invention. It is the scope of protection of the present invention.
