The circuit components are connected to the LED bead board 20 via a connecting wire. This connecting wire passes through the telescopic rod 31, the connector 32, and the rotating shaft 37 before extending into the lamp head rear shell 19. The battery 11 then supplies power to the LED bead board 20.

[0054] The display screen 8 is used to display the battery level, and the button 6 is used to turn the LED board 20 on or off. Open the socket cover 7 to charge the battery 11 through the charging port.

[0055] Working principle:

[0056] In use, rotate the support leg 35 to disengage the locking strip from the silicone pad 17, causing the support leg 35 to open away from the telescopic rod 31. The support leg 35 will move the open end of the support rod 12, and the other end of the support rod 12 will rotate on the telescopic sleeve 36. At the same time, the other end of the support rod 12 will pull the telescopic sleeve 36 upward, causing the telescopic rod 31 to move upward, allowing the telescopic rod 31 to slide upward within the light guide 2.

[0057] After the three support legs 35 are opened to a certain angle, the telescopic sleeve 36 can be pushed upwards directly. The movement of the telescopic sleeve 36 will push the support legs 35 to rotate through the support rod 12, causing the support legs 35 to open to the side away from the telescopic rod 31.

[0058] After the support leg 35 is extended, it supports the lighting fixture. The telescopic sleeve 36 is located above the support surface.

[0059] Moving the telescopic rod 31 upwards will cause the connector 32 and the lighting head 33 to move upwards. The height of the connector 32 can be adjusted via the telescopic rod 31.

[0060] Handheld lighting head 33. The lighting head 33 can be rotated in the horizontal direction, so that the bottom ends of the first rotating shaft 25 and the second rotating shaft 26 can rotate within the connector 32.

[0061] The lamp head 33 can also be rotated independently, causing it to swing vertically. This causes the lamp head back cover 19 and the rotating shaft clamp 22 to rotate on the first rotating shaft 25 and the second rotating shaft 26, and the screws will rotate together.

[0062] During rotation, the slot rotates on the locking block, and the spring 24 remains compressed throughout the process. After rotation, the spring 24 positions the locking block within the slot, thereby fixing the position of the lighting head 33.

[0063] Therefore, the mirror 21 can be rotated to fit against the top surface of the light guide 2, allowing the light emitted from the LED board 20 to pass through the mirror 21 and enter the light guide 2. The light source then enters the lampshade 1 through the light guide 2 on the lampshade 1, and then diffuses through the through-hole. The light guide 2 weakens the light intensity, allowing the lamp to function as an ambient light.

[0064] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
