At this time, the light source 10 is vertically downward to illuminate the desktop to meet the needs of nighttime study.

[0022] The threaded sleeve 7 is sleeved on the outside of the first threaded column 5, and the threaded sleeve 7 is threadedly matched with the first threaded surface 51 opened on the outside of the first threaded column 5 and the second threaded surface 81 opened on the outside of the second threaded column 8. The threaded sleeve 7 is provided with a condenser 6 with light-condensing ability on the side away from the mounting head 4. The threaded sleeve 7 can be rotated on the outside of the first threaded column 5 and the second threaded column 8, and can be rotated from the first threaded column 5 to the outside of the second threaded column 8. By continuing to rotate the threaded sleeve 7, the condenser 6 at the end of the threaded sleeve 7 can be moved to the vicinity of the light source 10, and the relative position of the light source 10 and the condenser 6 can be adjusted, thereby converging the divergent light source and changing the lighting angle to meet the use requirements in different scenes.

[0023] In order to realize the function of focusing light, the focusing cover 6 is a conical cover body, and the diameter of the port where the focusing cover 6 is connected to the threaded sleeve 7 is larger than the diameter of the port at the other first end of the focusing cover 6. The focusing cover 6 is a focusing component commonly used in existing lamps, and no further explanation is given.

[0024] Specifically, the height adjustment bracket includes a fixed tube 2 and an adjustment rod 3, the lower end of the fixed tube 2 is fixedly connected to the upper end of the pad 1, the lower end of the adjustment rod 3 penetrates into the upper port of the fixed tube 2 and is slidably connected to the inner wall of the fixed tube 2, a positioning assembly is provided at the connection between the fixed tube 2 and the adjustment rod 3, and the upper end of the adjustment rod 3 is fixedly connected to the lower end of the mounting head 4. The lower end of the adjustment rod 3 enters and exits the fixed tube 2 and is pulled and rotated along the inner wall of the fixed tube 2. By rotating the fixed tube 2, the irradiation direction of the light source 10 can be adjusted, and by pulling the adjustment rod 3, the height of the light source 10 can be adjusted, wherein the positioning assembly plays a role in locking the position of the adjustment rod 3.

[0025] More specifically, the positioning assembly includes a positioning hole 13 formed on the outside of the fixing tube 2, the positioning hole 13 is located at one end of the fixing tube 2 close to the adjusting rod 3, and a fixing bolt 14 is provided on the positioning hole 13, the fixing bolt 14 penetrates into the fixing tube 2 and is threadedly connected with the positioning hole 13. When the position of the adjusting rod 3 is locked, the fixing bolt 14 is rotated, and the fixing bolt 14 is screwed into the fixing tube 2, and the fixing bolt 14 abuts against the outer wall of the adjusting rod 3 to clamp the adjusting rod 3.
