[0037] Please refer to Figures 1 to 2 , an adjustable focus dyeing lamp provided by an embodiment of the present utility model includes a light source assembly 1;

[0038] A focusing assembly 2 includes two nested focusing parts 20. The focusing parts 20 are movably arranged on the light source assembly 1. A lens part 21 is provided on the first end surface of the focusing part 20, and the light incident surface of the lens part 21 corresponds to the light rays of the light source of the light source assembly 1;

[0039] A driving assembly 3 is connected to the second end surface of the focusing part 20 and is used to drive the focusing part 20 to reciprocate along the direction of the light rays of the light source.

[0040] In this embodiment, the two nested focusing parts 20 are taken as an inner ring focusing part 20 and an outer ring focusing part 20 respectively for detailed description.

[0041] Specifically, the innovation of the present utility model lies in that the outer ring focusing part 20 and the inner ring focusing part 20 can be respectively controlled by the driving assembly 3 to realize the movement of the outer ring focusing part and / or the inner ring focusing part 20, so that the light rays of the light source assembly 1 can obtain different light effects after passing through the light-transmitting lens part 21. Moreover, the driving assembly 3 can control the moving stroke of the inner ring focusing part 20 and the outer ring focusing part 20 to further refine different light effects, thereby meeting various focusing requirements.

[0042] In a possible implementation scheme, in order to facilitate the setting of the focusing part 20 that can move along the irradiation direction of the light source assembly 1 in the dyeing lamp, the present utility model is provided with a guiding slide column 201, and a first guiding hole for the guiding slide column 201 to pass through is opened on the light source assembly 1. In terms of structure, the space of the dyeing lamp can be fully utilized to improve the space utilization rate of the dyeing lamp. Specifically, the focusing part 20 of the above adjustable focus dyeing lamp includes a mounting plate 200 and a guiding slide column 201. The guiding slide column 201 is vertically installed on the mounting plate 200. One end of the guiding slide column 201 away from the mounting plate 200 is connected with the lens part 21. A first guiding hole for the guiding slide column 201 to pass through is provided on the light source assembly 1. A slider 202 is further provided on the mounting plate 200. The driving assembly 3 includes a lead screw, and the lead screw is threadedly connected with the slider 202. The lead screw drives the slider 202 to reciprocate along the axial direction of the lead screw. By setting the slider 202 on the mounting plate 200, the driving assembly 3 drives the lead screw to rotate around its own axis, and then drives the slider 202 to move, realizing the movement of the focusing part 20.

[0043] In a possible implementation, a limit sliding sleeve 203 is further sleeved on the outer periphery of the guiding sliding column 201 of the above-mentioned focus-adjustable dyeing lamp, and the limit sliding sleeve 203 is used to limit the movement stroke of the guiding sliding column on the light source assembly 1. Specifically, please refer to Figure 2 and Figure 3 , when the driving component 3 drives the lead screw to rotate, the slider 202 is driven to move along the axial direction of the lead screw. When the lead screw rotates a certain number of turns, the limit sliding sleeve 203 can abut against the light source assembly 1 to prevent the guiding sliding column 201 from moving further. By setting the limit sliding sleeve 203, the movement stroke of the guiding sliding column 201 can be effectively controlled, the structural stability of the focus-adjusting component 2 can be ensured, and the slider 202 can be prevented from falling off due to excessive rotation of the lead screw.

[0044] In a possible implementation, the driving component 3 of the above-mentioned focus-adjustable dyeing lamp further includes a stepper motor 31, the stepper motor 31 is fixedly arranged on the light source assembly 1, and the stepper motor 31 is connected to the lead screw.

[0045] The stepper motor 31 is a motor that converts an electrical pulse signal into a corresponding angular displacement or linear displacement. For each input pulse signal, the rotor rotates an angle or moves forward one step. Its output angular displacement or linear displacement is proportional to the number of input pulses, and the rotational speed is proportional to the pulse frequency. Therefore, the stepper motor 31 can accurately control the rotation amplitude of the lead screw, and thus can accurately position the moving distance of the guiding sliding column 201. Specifically, in this embodiment, each of the two nested focus-adjusting parts 20 is provided with a stepper motor 31, and each focus-adjusting part 20 realizes movement through its own stepper motor 31. During the process of driving the focus-adjusting part 20 to move along the axial direction of the lead screw, the stepper motor 31 can be matched according to the thread density of the lead screw and the slider 202 and the diameter of the lead screw, and the short-distance displacement of the guiding sliding column 201 is realized through the lead screw and the thread density on the lead screw.

[0046] In another implementable manner, the driving component 3 can also be driven by a push rod motor. When the driving component 3 is a push rod motor, at this time, the piston rod of the push rod motor is directly connected to the mounting plate 200.

[0047] In a possible implementation, in order to further enrich the lighting rendering effect of the dyeing lamp, please refer to Figure 4 , the light source assembly 1 of the above-mentioned focus-adjustable dyeing lamp includes a base 11, a lamp bead board 12 and a plurality of lamp beads 13. The base 11 is connected to the lamp bead board 12, and the plurality of lamp beads 13 are evenly distributed on the lamp bead board 12; a receiving space for receiving the mounting plate 200 is formed between the base 11 and the lamp bead board 12, and the first guiding hole is provided on the lamp bead board 12.

[0048] In a possible implementation, the above-mentioned focus-adjustable dyeing lamp further includes a radiator 4, the radiator 4 is arranged on the accommodation space, and the heat source acting surface of the radiator 4 is attached to the lamp bead board 12. A second guiding hole for the guiding slide column 201 to pass through is provided on the radiator 4.

[0049] Specifically, the radiator 4 is arranged on the setting base 11. Therefore, an avoidance cavity for placing the driving assembly 3, such as a stepper motor 31, needs to be dug on the radiator 4. The stepper motor 31 is housed in this avoidance cavity, and the heat source acting surface of the radiator 4 is attached to the lamp bead board 12 to realize the two functions of focus adjustment and heat dissipation.

[0050] In a possible implementation, the lens part 21 of the above-mentioned focus-adjustable dyeing lamp includes a plurality of lenses 210, a lens pressing plate 211, and a lens fixing plate 212. The plurality of lenses 210 are installed on the lens pressing plate 211, the lens fixing plate 212 clamps the lens pressing plate 211, and the lenses 210 correspond to the lamp beads 13 one by one.

[0051] In a possible implementation, the above-mentioned focus-adjustable dyeing lamp further includes a magnet 5 and a Hall element 6. The magnet 5 is arranged on the lens part 21, the Hall element 6 is arranged on the light source assembly 1, the magnet 5 and the Hall element 6 are arranged opposite to each other, and the Hall element 6 collects the magnetic field change information of the magnet 5.

[0052] In practical applications, different lenses 210 in the lens part 21 have different focus adjustment effects, and the distance between the lens 210 and the light source assembly 1 also has different focus adjustment effects. To facilitate the precise control of the focus adjustment effect of the lens part 21, in this embodiment, a magnet 5 and a Hall element 6 are arranged on the dyeing lamp, and the displacement amount of the adjustment part is obtained in real time through the Hall element 6, so that the user can perform fine control in real time.

[0053] When the driving assembly 3 drives the focus adjustment part 20 to move along the irradiation direction of the light source assembly 1, the Hall element 6 acquires the magnetic field change information of the magnet 5, and then transmits this magnetic field change information to the dyeing lamp. After the dyeing lamp processes this magnetic field change information, the processed information is fed back to the user terminal (such as a console, a mobile terminal with software, etc.).

[0054] In a possible implementation, the above-mentioned Hall element 6 of the focus-adjustable dyeing lamp includes an induction element and an information processing element. The induction element is used to sense the magnetic field change information of the magnet 5, and the information processing element is used to output the displacement amount of the lens part 21 according to the magnetic field change information.

[0055] The induction element can select a Hall chip. The Hall chip can concentrate the magnetic field signal of the magnet 5 and convert the magnetic field signal into a digital signal representing the current angle value. A magnetic flux concentrating sheet (IMC) is provided in the Hall chip. The magnetic flux concentrating sheet can concentrate the magnetic field acting parallel to the surface of the Hall chip and generate a vertical component proportional to the magnetic field at the edge of the IMC structure. Then, two pairs of conventional planar Hall elements 6 located below the IMC are used to measure this signal.

[0056] Compared with the prior art, the utility model can obtain a variety of different light effect effects by providing two mutually nested focusing parts 20 on the dyeing lamp and enabling the common or independent movement of the focusing parts 20 through the driving assembly 3.
