Description

Technical Field

[0001] The utility model relates to the technical field of LED imaging lamps, and more specifically, to a zoomable LED imaging lamp. Background Art

[0002] As a special type of lamp, LED imaging light has unique working principle and advantages. Its core lies in using LED as light source and achieving high-quality imaging effect through specific design and technology.

[0003] Existing LED imaging lights still face challenges in some aspects, among which the difficulty in changing the focal length and the poor optical performance of the imaging lights are two major problems. These problems have limited the application of LED imaging lights in the fields of stage, film and television to a certain extent, and it is difficult to meet the diverse needs of consumers. First, regarding the change of focal length, the design of existing LED imaging lights often fixes the focal length, which makes it difficult to flexibly adjust according to needs in actual use. The fixed focal length not only limits the applicability of the lamp in different scenes, but also may affect the clarity and layering of the image. In stage performances, the change of focal length is crucial to highlight the details of the performers and create different visual effects. Therefore, LED imaging lights that lack focal length adjustment function seem to be unable to cope with the diverse stage needs. Secondly, the poor optical performance of imaging lights is also a problem that needs to be solved urgently. Poor optical performance may manifest itself in uneven light distribution, inaccurate color reproduction, glare and other problems. These problems not only affect the audience's visual experience, but may also interfere with the performers' performance. In stage performances, lighting is an important means to create an atmosphere and highlight the theme, and poor optical performance of imaging lights will directly affect the presentation of stage effects. Therefore, improving the optical performance of LED imaging lights is crucial to improving stage effects. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figures 1 to 5 As shown, the utility model provides a variable-focus LED imaging lamp, comprising a housing 1, a bracket 2 is fixedly installed inside the housing 1, a lamp 3 is fixedly installed inside the bracket 2 and extends to both ends, and a lens 4 is fixedly installed at one end of the lamp 3;

[0024] Rectangular grooves 5 are provided on the inner walls of both sides of the housing 1. Slide blocks 8 are movably installed inside the two rectangular grooves 5. A lens 2 11 is fixedly installed between the two slide blocks 8. An electric push rod 7 is fixedly installed at one end of the slide block 8.

[0025] A slide groove 6 is provided inside the rectangular groove 5, and a protrusion 9 is movably installed inside the slide groove 6, and the protrusion 9 is fixedly connected to the slider 8;

[0026] A spring 10, wherein the spring 10 is arranged between the rectangular groove 5 and the slider 8;

[0027] When in use, the staff starts the electric push rod 7 through the external switch, and the round rod inside the electric push rod 7 pushes the slider 8 to move forward, thereby driving the lens 2 11 to move forward synchronously, so that the spring 10 is in a compressed state. At the same time, when the slider 8 moves, the protrusions 9 at the upper and lower ends thereof move inside the slide groove 6, thereby changing the position of the lens 2 11 inside the housing 1, thereby achieving zooming;

[0028] The thrust of the electric push rod 7 causes the slider 8 to move, and the protrusions 9 at the upper and lower ends thereof move inside the slide groove 6. The movement of the slider 8 drives the lens 2 11 to move. Compared with the traditional device, this device can achieve a zoom effect by changing the distance between the lens 2 11 and the lens 1 4. This device has a simple structure, strong practicality, and a good zoom effect.

[0029] A filter plate 12 is fixedly installed inside the housing 1, a generator 13 is fixedly installed at one end of the filter plate 12, and a fan 14 is movably installed at the other end of the filter plate 12, and the generator 13 and the fan 14 are electrically connected;

[0030] When the device is in use, a large amount of heat is generated inside the housing 1. At this time, the staff starts the generator 13. The electricity stored in the generator 13 causes the fan 14 to rotate through the electrical connection. The rotation of the fan 14 discharges the heat inside the housing 1 through the heat dissipation slot 15.

[0031] The electricity from the generator 13 causes the fan 14 to rotate, and the rotation of the fan 14 discharges the heat inside the housing 1 through the heat dissipation slot 15. Compared with the traditional device, this device can ensure that the device maintains a stable and efficient working state for a longer period of time by dissipating the heat inside the housing 1, thereby extending the service life of the device. Excessive temperature may cause unstable performance of the device. By dissipating heat, it can ensure that the device operates within an appropriate temperature range, thereby maintaining stable performance output and improving imaging quality.

[0032] Among them, a heat dissipation groove 15 is opened on one end surface of the housing 1, and the number of the heat dissipation grooves 15 is eight;

[0033] A heat dissipation groove 15 is provided on one end surface of the housing 1 , through which the heat generated inside the housing 1 can be discharged. Eight groups of heat dissipation grooves 15 make the discharge efficiency higher, thereby greatly reducing the occurrence of accidents.

[0034] Wherein, fixed blocks 16 are fixedly installed on both end surfaces of the housing 1, a connecting rod 17 is movably installed between the two fixing blocks 16, and an anti-slip pad 18 is provided on the surface of the connecting rod 17;

[0035] Fixed blocks 16 are fixedly installed on the surfaces of both ends of the shell 1, and a connecting rod 17 is movably installed between the two fixing blocks 16. An anti-skid pad 18 is arranged on the surface of the connecting rod 17. By rotating the connecting rod 17, the device can be stably installed on the stage surface, and the anti-skid pad 18 can increase the friction with the stage surface, making the device more stable.

[0037] A rubber ring 19 is fixedly mounted on the surface of the housing 1, which makes it more convenient for the staff to take the device. The inner diameter of the rubber ring 19 is equal to the outer diameter of the housing 1, so that the rubber ring 19 fits better with the housing 1 and the use effect is better.

[0038] The working principle and use process of this utility model:

[0039] When in use, the staff starts the electric push rod 7 through the external switch, and the round rod inside the electric push rod 7 pushes the slider 8 to move forward, thereby driving the lens 2 11 to move forward synchronously, so that the spring 10 is in a compressed state. At the same time, when the slider 8 moves, the protrusions 9 at the upper and lower ends thereof move inside the slide groove 6, thereby changing the position of the lens 2 11 inside the housing 1, thereby achieving zooming.

[0040] When the device is in use, a large amount of heat is generated inside the housing 1. At this time, the staff starts the generator 13. The electricity stored in the generator 13 causes the fan 14 to rotate through the electrical connection. The rotation of the fan 14 discharges the heat inside the housing 1 through the heat dissipation slot 15.
