Description

Technical Field

[0001] The utility model relates to the technical field of stage lights, and more specifically, to a portable sealed color-changing light. Background Art

[0002] In the existing color-changing light technology, most lamps drive a lens assembly to move along a direction close to or away from a light source through a driving assembly to adjust the state of a light spot. However, when these color-changing lights are applied outdoors, since they need to work under various weather conditions, their waterproof performance requirements are relatively high, which usually means that their outer shells must have good sealing performance to prevent rainwater or moisture from entering the inside of the lamp body.

[0003] Meanwhile, to solve the heat dissipation problem, because metal has good heat conduction performance, which helps to quickly dissipate the heat generated inside the lamp body, these color-changing lights usually adopt a metal outer shell that has both fast heat dissipation and good sealing performance. However, the adoption of a metal shell also brings additional weight, resulting in an increase in the weight of the entire lamp. In addition, the thick metal outer shell will also increase the volume of the lamp, making the lamp appear bulky and even inconvenient to move or install. In the existing solutions, the outer shell is a single-layer structure. In this case, the waterproof performance of the color-changing light will face challenges, which may in turn cause water leakage problems. This will not only affect the normal operation of the lamp, but may also damage the internal circuit and shorten the service life of the lamp.

[0004] In summary, there are certain limitations in the waterproof, heat dissipation and structural design of the existing color-changing lights, and a new solution is urgently needed to improve these deficiencies to meet the high waterproof, high heat dissipation and lightweight requirements for outdoor applications. Summary of the Utility Model

[0005] The utility model aims to overcome at least one of the above-mentioned defects of the prior art, and provides a portable sealed color-changing light. By adopting the telescopic cylinder, a sealed cavity with good waterproof performance is formed among the lens assembly, the telescopic cylinder and the installation cylinder body, and at the same time, the overall volume of the lamp is effectively reduced and the weight is lightened.

[0006] To solve the above technical problems, the technical solution adopted by the utility model is: to provide a portable sealed color-changing light, including: a light source for generating light; an installation cylinder body forming an installation cavity with an opening and used for accommodating the light source; a lens assembly located outside the installation cylinder body and used for receiving the light emitted from the opening by the light source and integrating it to form at least one light beam; a driving assembly for driving the lens to move along a direction close to or away from the light source; a telescopic cylinder with one end connected to the lens assembly and the other end connected to the end of the installation cylinder body provided with the opening; the inner side wall of the installation cylinder body, the inner side wall of the telescopic cylinder and the inner side surface of the lens assembly jointly form a sealed cavity.

[0007] The installation cylinder body provides an installation position for the light source and other electronic components, and the telescopic cylinder is connected to both the installation cylinder body and the lens assembly at the same time, so that the light source and the electronic components are both located in a closed space with good waterproof performance, effectively preventing water vapor and dust impurities from entering and affecting them. At the same time, the telescopic cylinder has good elasticity. During the process of the driving assembly driving the lens assembly to move, the telescopic cylinder can follow the lens assembly to change its extended or folded form, having good waterproof performance and strong flexibility at the same time, and the structure is simple. Compared with the traditional waterproof housing, the addition of the telescopic cylinder body effectively reduces the volume of the lamp and greatly reduces the weight of the whole lamp.

[0008] Furthermore, it further includes a radiator with a heat dissipation substrate. The heat dissipation substrate seals the bottom of the end of the installation cylinder body away from the opening, forming a part of the inner side wall of the installation cylinder body. The substrate can more directly absorb the heat inside the installation cylinder body and transfer it outside the closed cavity to achieve efficient heat dissipation.

[0009] Furthermore, it further includes a first housing that wraps the radiator and is buckled on the bottom of the installation cylinder body. The first housing has heat dissipation holes communicating with the outside. Using the first housing to wrap the radiator makes the appearance of the lamp body more integral. At the same time, the setting of the heat dissipation holes also improves the efficiency of the radiator to dissipate heat to the outside.

[0010] Furthermore, it further includes a mounting frame fixed to the lens assembly. The mounting frame is fixedly connected to the driving assembly. Driven by the driving assembly, the mounting frame drives the lens assembly to move in a direction away from or close to the light source, and the telescopic cylinder correspondingly makes a form change of extension or folding at the same time. By setting the mounting frame, the fixation among the lens assembly, the driving assembly and the telescopic cylinder is more convenient. It not only provides a more stable support structure for the driving assembly, but also ensures the smoothness of the lens assembly during movement; when the lens assembly moves away from the light source, the telescopic cylinder is in an extended state, and when the lens assembly moves close to the light source, the state of the telescopic cylinder switches to a folded form, having good adjustability.

[0011] Furthermore, the telescopic cylinder is connected to a side surface of the lens assembly close to the light source. The telescopic cylinder is used to connect the lens assembly and the light source. Through such a setting, the edge of the telescopic cylinder does not need to wrap the lens assembly for connection, and only needs to be connected below it, effectively reducing the volume occupied by the telescopic cylinder.

[0012] Further, it further includes a pressing plate which tightly presses the end of the telescopic cylinder to install it on the edge of the installation cylinder body and / or the edge of the lens assembly. Using the pressing plate can ensure the stability of the connection.

[0013] Further, the light source includes at least two light-emitting bodies and a light guide rod closely arranged on the light-emitting bodies. The light guide rod fully mixes the light emitted by the light-emitting bodies, correspondingly forms uniform small light beams, and then enters the lens assembly.

[0014] Further, the lens assembly includes a lens for changing the light exit direction and a mounting substrate for mounting the lens. The lens is at least one of a Fresnel lens, a frosted lens or a magnifying lens. When the lens is a Fresnel lens, the lens can evenly focus or disperse the light to the area to be illuminated, providing a more uniform and concentrated light spot. At the same time, for the thickness and weight of a traditional lens, the Fresnel lens can significantly reduce the material usage through its segmented structure, making the optical system lighter; when the lens is a frosted lens, the lens equalizes the light beam, thereby projecting a light spot with uniform brightness and color; when the lens is a magnifying lens, as the lens assembly moves, the size of the formed light spot correspondingly becomes larger or smaller.

[0015] Further, it further includes an anti-glare lens barrel arranged on the side of the lens assembly away from the light source. It reduces unnecessary glare and light pollution, improves the light spot quality, and enhances the visual comfort of the audience.

[0016] Further, it further includes a second outer shell buckled on the outer periphery of the telescopic cylinder, the lens assembly and the installation cylinder body. The second outer shell is provided with a through hole for the anti-glare lens barrel to extend out. The second outer shell makes the outer periphery of the lamp body more integral. At the same time, the second outer shell can also block most of the external moisture or dust, further improving the waterproof and dustproof performance.

[0017] Further, it further includes a support arm pivotally connected to the installation cylinder body and a waterproof breathable valve. The inner cavity of the support arm is sealed and communicated with the closed cavity. The waterproof breathable valve is installed on the installation cylinder body and / or the support arm. During the operation of the dyeing lamp, the light source and other electronic components located in the closed cavity generate heat and heat the air in the closed cavity. The inner cavity of the support arm provides a heat dissipation space. When the hot air flows into the inner cavity of the support arm, the heat exchanges with the outside through the side wall of the support arm, so as to achieve the heat dissipation effect; since the closed cavity and the inner cavity of the support arm form a relatively sealed cavity, during the movement of the lens assembly, the volume of this cavity changes accordingly, resulting in the change of its internal air pressure. The setting of the waterproof breathable valve ensures that the air pressure inside the cavity is balanced with the outside and effectively blocks the entry of external moisture.

To better illustrate the present embodiment, some parts of the drawings may be omitted, enlarged, or reduced, and do not represent the size of the actual product. For those skilled in the art, it is understandable that some well-known structures and their descriptions may be omitted in the drawings. The positional relationships described in the drawings are only for illustrative purposes and cannot be construed as limiting the present invention.

[0026] like Figures 1 to 4As shown in the figure, a portable sealed dyeing lamp includes a light source 110 that generates light; a mounting cylinder 100 that forms a mounting cavity with an opening 120 and is used to accommodate the light source 110; a lens assembly 200 located outside the mounting cylinder 100, which is used to receive the light emitted by the light source 110 from the opening 120 and integrate it into at least one light beam; a driving assembly 300 that is used to drive the lens to move in a direction close to or away from the light source 110; a telescopic cylinder 400, one end of which is connected to the lens assembly 200, and the other end is connected to the end of the mounting cylinder 100 where the opening 120 is provided; the inner side wall of the mounting cylinder 100, the inner side wall of the telescopic cylinder 400 and the inner side surface of the lens assembly 200 together form a sealed cavity.

[0027] The mounting cylinder 100 provides a mounting position for the light source 110 and other electronic components, and the telescopic cylinder 400 is simultaneously connected to the mounting cylinder 100 and the lens assembly 200, so that the light source 110 and the electronic components are all located in a sealed space with good waterproof performance, effectively blocking the entry of water vapor, dust and impurities and affecting them. At the same time, the telescopic cylinder 400 has good elasticity. During the process of the driving assembly 300 driving the lens assembly 200 to move, the telescopic cylinder 400 can follow the lens assembly 200 to change its extended or folded form, having good waterproof performance and strong flexibility at the same time, and the structure is simple. Compared with the traditional waterproof housing, the addition of the telescopic cylinder 400 effectively reduces the volume of the lamp and greatly reduces the weight of the whole lamp.

The first housing 610 has heat dissipation holes 611 communicating with the outside. Using the first housing 610 to wrap the radiator 500 makes the appearance of the lamp body more integral. At the same time, the setting of the heat dissipation holes 611 also improves the efficiency of the radiator 500 in dissipating heat to the outside. The first housing 610 is fixedly fastened to the bottom of the mounting cylinder 100 by screws.

[0036] In a preferred embodiment of the present utility model, it further includes a mounting frame 210 fixed to the lens assembly 200.

By providing the mounting frame 210, the fixation among the lens assembly 200, the driving assembly 300, and the telescopic cylinder 400 becomes more convenient. It not only provides a more stable support structure for the driving assembly 300 but also ensures the smoothness of the lens assembly 200 during movement. When the lens assembly 200 moves away from the light source 110, the telescopic cylinder 400 is in an extended state.

Through such a setting, the edge of the telescopic cylinder 400 does not need to wrap the lens assembly 200 for connection, and only needs to be connected below it, effectively reducing the volume occupied by the telescopic cylinder 400.

[0041] Preferably, when the folding lamp cylinder is in a folded form, its diameter is smaller than the diameter of the opening 120 of the lens assembly 200 and / or the mounting cylinder body 100, which can effectively reduce the volume of the staining lamp.

[0047] In a preferred embodiment of the present invention, the lens assembly 200 includes a lens 230 for changing the light emission direction and a mounting substrate 220 for mounting the lens 230. The lens 230 is at least one of a Fresnel lens, a frosted lens, or a magnifying lens. When the lens 230 is a Fresnel lens, the lens 230 can evenly focus or disperse the light to the area to be illuminated, providing a more uniform and concentrated light spot. At the same time, for the thickness and weight of traditional lenses, the Fresnel lens can significantly reduce the material usage through the segmentation structure, making the optical system lighter; when the lens 230 is a frosted lens, the lens 230 equalizes the light beam, thereby projecting a light spot with uniform brightness and color; when the lens 230 is a magnifying lens, as the lens assembly 200 moves, the size of the formed light spot correspondingly becomes larger or smaller.

[0054] Preferably, the diameter of the anti-glare lens barrel 700 is only slightly larger than the diameter of the through hole 621 to prevent excessive water vapor or dust from entering.

[0055] As Figure 2 and Figure 5 shown, in a preferred embodiment of the present utility model, it further includes a support arm 800 pivotally connected to the mounting cylinder body 100 and a waterproof breathable valve 810. The inner cavity of the support arm 800 is sealed and communicated with the sealed cavity. The waterproof breathable valve 810 is installed on the mounting cylinder body 100 and / or the support arm 800. During the operation of the dyeing lamp, the light source 110 and other electronic components located in the sealed cavity generate heat and heat the air in the sealed cavity. The inner cavity of the support arm 800 provides a heat dissipation space. When the hot air flows into the inner cavity of the support arm 800, the heat exchanges with the outside through the side wall of the support arm 800, thereby achieving a heat dissipation effect; since the sealed cavity and the inner cavity of the support arm 800 form a relatively sealed cavity, during the movement of the lens assembly 200, the volume of the cavity changes accordingly, resulting in a change in its internal air pressure. The setting of the waterproof breathable valve 810 ensures that the air pressure inside the cavity is balanced with the outside and effectively blocks the entry of external moisture.
