[0026] Example
[0027] like Figure 1-4 As shown, this embodiment provides a focusable moving head wash lamp, comprising a base 1, the top of the base 1 is rotatably connected to a rocker arm assembly 2, the rocker arm assembly 2 is transmission-connected to a lamp head assembly 3, the lamp head assembly 3 comprises a lamp head housing 31, a light guide fixing bracket 32 is embedded inside the lamp head housing 31, a lamp board 5 is fixedly installed at the bottom of the light guide fixing bracket 32 by bolts, a plurality of LED lamp beads 51 are distributed in a circular array on the lamp board 5, a focusing mechanism is arranged inside the lamp head housing 31, a lens bracket 4 is movably connected to the top of the lamp head housing 31, a lens 41 is embedded at a position corresponding to the LED lamp beads 51, the number of the lenses 41 is the same as the number of the LED lamp beads 51, and the focusing mechanism is transmission-connected to the lens bracket 4, driving the lens bracket 4 to move up and down, so that the lens 41 is close to or away from the LED lamp beads 51, so as to achieve the effect of focusing. Moreover, in this embodiment, the number of the LED lamp beads 51 is 19.
[0028] Specifically, the focusing mechanism includes a motor bracket 61 fixedly connected to the bottom of the light guide fixed bracket 32 by bolts, and a focusing motor 62 is fixedly installed on the motor bracket 61 with screws. The motor bracket 61 passes through the light board 5 so that the focusing motor 62 is fixedly installed on the side of the light board 5 away from the light guide fixed bracket 32. The output shaft of the focusing motor 62 is transmission-connected with a screw rod 63, and a focusing bracket 64 is threadedly connected to the screw rod 63. One end of the focusing bracket 64 passes through the light board 5 and the light guide fixed bracket 32, and extends to the top of the shell and is fixedly connected to the lens bracket 4. The focusing motor 62 drives the screw rod 63 to rotate, and the rotation of the screw rod 63 drives the focusing bracket 64 to move forward and backward along the direction of the screw rod 63, thereby driving the lens bracket 4 to move up and down, so that the lens 41 is away from or close to the LED lamp bead 51, so as to achieve a focusing effect, realize the effect switching between dyeing and light beam, and improve the stage lighting effect.
[0029] Furthermore, a light guide channel 321 is provided at a position corresponding to the LED lamp bead 51 of the light guide fixing bracket 32. One end of the light guide channel 321 extends to the top of the LED lamp bead 51 and is in clearance with the LED lamp bead 51. The other end extends to a position close to the lens 41. A light guide rod 322 is embedded in the light guide channel 321. A light guide pressure plate 323 is fixedly connected to the top of the light guide fixing bracket 32. The top of the light guide rod 322 is fixedly connected to the light guide pressure plate 323. The light guide plate is fixed by the light guide pressure plate 323 to prevent the light guide rod 322 from loosening and moving. The light from the LED lamp bead 51 enters the light guide channel 321 and is guided by the light guide rod 322, which can prevent the light from the nearby LED lamp beads 51 from crossing each other and make the emitted light more uniform and bright.
[0030] Furthermore, a heat sink 52 is fixedly connected to the bottom of the lamp board 5 by bolts. The LED lamp beads 51 generate heat when working, and the heat is conducted away through the heat sink 52, thereby accelerating the heat dissipation efficiency and increasing the service life.
[0031] Furthermore, a cooling fan 7 is bolted and fixedly connected to the bottom of the lamp housing 31, and a plurality of cooling holes are provided at the bottom of the lamp housing 31.

The first driving wheel 24 is driven to rotate by the first motor 23, which drives the first driven wheel 25 to rotate, thereby driving the light guide fixed bracket 32 to rotate, so that the entire lamp head assembly 3 rotates to achieve swinging.
[0033] Specifically, the middle part of the top of the base 1 is rotatably connected to a second driven wheel 28, the second driven wheel 28 is fixedly connected to the U-shaped bracket 22, the bottom of the U-shaped bracket 22 is fixedly connected to a second motor 26, the output shaft of the second motor 26 is fixedly connected to a second driving wheel 27, and the second driving wheel 27 and the second driven wheel 28 are connected through a second synchronous belt transmission. Similarly, the second motor 26 drives the second driving wheel 27 to rotate, driving the second driven wheel 28 to rotate, thereby driving the entire U-shaped bracket 22 to rotate, thereby driving the lamp head assembly 3 to rotate, thereby achieving a rotation effect of the lamp head assembly 3.
[0034] Furthermore, two origin sensors 29 are included, and the two origin sensors 29 are respectively fixedly connected to the two sides of the bottom of the U-shaped bracket 22, and the two origin sensors 29 are respectively used to detect the origin positions of the first driving wheel 24 and the second driving wheel 27. When the lamp is turned off, the origin positions of the first driving wheel 24 and the second driving wheel 27 are detected by the two origin sensors 29 to reset.
[0035] Specifically, the base 1 is internally bolted and fixedly connected with a control panel, and a display screen 11 and a control button 12 are integrated on the control panel. The display screen 11 is used to display parameters, and the control button 12 is used to adjust parameters to control the lamp to work. A signal receiving interface 14, a signal sending interface 15 and a power socket 13 are embedded on one side of the base 1. A power supply is provided inside the base 1, and the power socket 13 is connected to the power supply. The power socket 13 connects the external power supply to power the lamp or charges the internal battery by inserting a power cord. The signal receiving interface 14 and the signal sending interface 15 are used to connect multiple lamps in series, and the model receiving interface of one of the lamps is connected to the host computer, so that all the lamps are uniformly controlled by the host computer.
[0036] Furthermore, the bottom of the base 1 is detachably connected with a hanger 10. The hanger 10 can be used for hoisting, or the hanger 10 can be disassembled and directly placed for use.
[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them.
