Description

Technical Field

[0001] This utility model relates to the field of lighting product technology, and in particular to a moving head light with a honeycomb lens array. Background Technology

[0002] With the rapid development of cultural and entertainment performances, concerts, and large-scale stage design projects, stage lighting has increasingly higher requirements for beam shape, dynamic effects, and equipment reliability. Moving head lights, which combine the functions of beam lights, color-changing lights, and special effects lights, have become one of the mainstream choices for stage lighting equipment.

[0003] Stage performances often take place outdoors or in venues with complex environmental conditions. When traditional bee-eye moving head lights are used in such scenarios, the lenses are prone to fogging due to environmental changes, affecting the beam effect and stage performance. For example, after rain or in an outdoor night performance, the ambient humidity is usually high. When the lights are paused or in standby mode, the temperature of the lens at the front of the light head drops rapidly below the dew point, and moisture in the air easily condenses on its surface, forming a fog layer. This not only causes blurred light spots and reduced brightness but also affects the normal progress of subsequent performances, requiring extra time for manual defogging or waiting for the equipment to warm up and recover.

[0004] Similar problems exist even in indoor environments such as air-conditioned theaters. When the lights are turned off after prolonged high-power operation, the lenses remain at a relatively high temperature. When the cold air from the air conditioner blows directly onto the light head, the surface temperature of the lenses drops sharply, easily causing condensation and fogging. Existing anti-fog designs mostly rely on heating films or localized fans, but the airflow coverage is limited, making it difficult to achieve comprehensive and uniform defogging. At the same time, the lens fixing structure and ventilation and heat dissipation paths are often set up independently, resulting in complex structures, large space occupation, and inconvenient assembly and maintenance. Therefore, there is an urgent need for an improved beehive moving head light that can achieve efficient ventilation and defogging while also ensuring stable lens positioning, heat dissipation performance, and structural compactness, to better adapt to the needs of complex performance environments. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, the technical problem to be solved by this utility model is to propose a moving head light with a honeycomb lens array, and the following technical solution is adopted:

[0006] A moving head light with a honeycomb lens array includes a base, a support arm, and a light box. The light box is formed by fastening a front cover and a rear cover of the lamp head. Inside, there are lens mounting components, a lamp body assembly, and a heat dissipation assembly. The lens mounting components include a front cover plate and a base plate. The base plate is provided with a plurality of mounting seats for placing lenses. The front cover plate is provided with a plurality of light-transmitting holes corresponding to the positions of the lenses. Reinforcing ribs are provided between adjacent light-transmitting holes. The plurality of reinforcing ribs surround to form a conical cavity. The opening of the conical cavity faces the base plate, and the side wall is provided with a guide hole. The base plate is provided with a first ventilation hole corresponding to the position of the conical cavity.

[0007] The aforementioned lamp head front cover is provided with an air inlet, and the aforementioned lamp head rear cover is provided with an air outlet. The aforementioned air inlet, guide hole, first ventilation hole and air outlet form a ventilation path.

[0008] As a further improvement, a fixing plate is provided between the front cover plate and the bottom plate. The fixing plate is provided with a plurality of limiting holes for fixing the position of the lens. A second ventilation hole is provided between the plurality of limiting holes. The opening of the conical cavity is aligned with the second ventilation hole, and the edge of the opening abuts against the fixing plate.

[0009] As a further improvement, an elastic sealing ring is provided on the inner wall of the aforementioned limiting hole.

[0010] As a further improvement, the light-transmitting hole array of the aforementioned front cover includes a central light-transmitting hole and six fan-shaped light zones surrounding the central light-transmitting hole, each of the aforementioned fan-shaped light zones having a fan angle of 60°.

[0011] As a further improvement, the conical cavity within the aforementioned fan-shaped cavity is a triangular pyramid, and the conical cavity between two adjacent fan-shaped lamp areas is a quadrangular pyramid. Each side of the aforementioned conical cavity is provided with the aforementioned guide hole.

[0012] As a further improvement, bolt holes are provided in several of the aforementioned conical cavities, and the aforementioned base plate is fixedly connected to the aforementioned front cover plate by bolts through the aforementioned bolt holes.

[0013] As a further improvement, the lamp head front cover and the lamp head rear cover are fixedly connected by bolts, and the side wall of the lamp head front cover is provided with a plurality of clearance grooves for the bolts to enter, and the air inlet is provided between the plurality of clearance grooves.

[0014] As a further improvement, the aforementioned lamp head front cover is equipped with a windshield.

[0015] As a further improvement, the aforementioned windshield is an electronically atomized glass.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] Firstly, this utility model, through a lens mounting assembly formed by a front cover plate, a base plate, and a fixing plate, creates a multifunctional structure integrating limiting, airflow guiding, fastening, and heat dissipation while ensuring precise lens positioning. Specifically, multiple reinforcing ribs on the front cover plate enclose a conical cavity, with airflow guiding holes on the sidewalls of the conical cavity. The base plate and fixing plate have ventilation holes at corresponding positions. The front cover of the lamp head has an air inlet, and the rear cover has an air outlet. The air inlet, airflow guiding holes, the first ventilation hole, and the air outlet together form a continuous and independent ventilation path. This ventilation path can form a stable airflow guide during lamp operation or standby, continuously blowing on the area above and around the lens, promptly removing moisture and heat, effectively preventing condensation and fogging on the lens surface due to sudden changes in ambient temperature. It is particularly suitable for complex working conditions such as after rain, open-air night performances, high humidity, or drastic temperature differences.

[0018] Secondly, in this invention, the opening edge of the conical cavity can directly abut against the fixing plate or the upper surface of the lens, effectively limiting and fixing the lens, preventing lens displacement, and ensuring the consistency of the light projection direction and spot of the lamp. Bolt holes are pre-set inside the conical cavity, allowing bolts to be directly inserted to secure the base plate and front cover plate, eliminating the need for external installation space, improving structural compactness, simplifying assembly, and facilitating mass production and subsequent maintenance. The overall design highly integrates the lens fixing structure with the ventilation and heat dissipation function, effectively overcoming the problems of traditional moving head lights where the lens fixing structure and heat dissipation / anti-fog design are independent, complex to assemble, and occupy a large space.

[0031] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings:

[0032] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. The terms "part," "side," "end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this utility model.

[0033] This utility model provides a moving head light with a honeycomb lens array, including a base 200, a support arm 300, and a light box 100. The base 200 supports and mounts the overall structure of the light fixture and can be fixedly connected to an external support frame or mounting platform. The support arm 300 is rotatably connected to the base 200. Specifically, the lower end of the support arm 300 is connected to the base 200 via a rotating shaft structure and is equipped with a corresponding drive motor or transmission mechanism to achieve horizontal rotation of the support arm 300 on the base 200, i.e., horizontal adjustment of the light fixture. The light box 100 is rotatably connected to the upper end of the support arm 300. Specifically, the light box 100 is connected to the support arm 300 via another rotating shaft structure and is driven by a corresponding drive motor to achieve vertical rotation of the light box 100 on the support arm 300, i.e., vertical adjustment. In one specific embodiment, the horizontal rotation range is 540°, and the vertical moving head range is 270°, both being stepless rotations. At the control level, this luminaire is compatible with DMX512 and RDM protocols and can be optionally equipped with Art-Net or sACN network control. Through linear, logarithmic, or S-curve dimming modes, it achieves smooth brightness transitions and rich beam effects, and includes several pre-set built-in programs such as "vortex," "starry sky," and "slender waist." This structure allows the lightbox 100 to rotate freely in both horizontal and vertical directions, enabling precise control of the beam projection direction within the space and adapting to the lighting effect requirements of various complex stage scenes.

[0034] like Figure 1 and Figure 2 As shown, the lightbox 100 is formed by fastening together a front cover 110 and a rear cover 120. The front cover 110 and the rear cover 120 are fixed together by snaps, screws, or other suitable connection methods to accommodate the internal components and protect them from external environmental interference. The lightbox 100 contains a lens mounting assembly, a lamp body assembly, a focusing assembly, and a heat dissipation assembly. The lamp body assembly includes multiple LED beads and a corresponding light source circuit board, used to emit high-brightness beams required for stage performances or shows.

[0035] like Figure 2 As shown, the lens mounting assembly is located at the front end of the light box 100, including a front cover plate 1 and a base plate 2. The base plate 2 is provided with several mounting seats 21 for placing and positioning the lenses 4. The mounting seats 21 may be further provided with precise positioning steps to ensure the stability of the lens 4. The front cover plate 1 is provided with several light-transmitting holes 11 corresponding to the positions of the lenses 4. The light-transmitting holes 11 allow the light beam to pass through smoothly. Reinforcing ribs 12 are provided between adjacent light-transmitting holes 11 to improve the rigidity and stability of the overall structure. Figure 3As shown, several reinforcing ribs 12 surround and form an inwardly protruding conical cavity 13. The opening of the conical cavity 13 faces the base plate 2, and a guide hole 14 is provided on the side wall. The base plate 2 has a first ventilation hole 22 corresponding to the position of the conical cavity 13. An air inlet 111 is provided on the side of the lamp head front cover 110, and an air outlet 121 is provided on the lamp head rear cover 120. A complete and continuous ventilation path is formed through the air inlet 111, the guide hole 14 on the conical cavity 13, the first ventilation hole 22 on the base plate 2, and the air outlet 121 on the lamp head rear cover 120.

[0036] The heat dissipation assembly is located at the rear of the light box 100. This assembly typically includes a fan, heat sink, or heat pipes to promptly remove heat generated by the LEDs and lenses 4, preventing excessive heat buildup inside the light box 100 and ensuring continuous and stable operation of the luminaire. The heat dissipation assembly (such as a combination of a fan and heat sink fins) inside the light box 100 creates a rearward airflow during operation, rapidly drawing hot air out of the light box 100 and expelling it through the air outlet 121 on the rear cover. Simultaneously, external air is drawn in through the air inlet 111 of the front cover 1 and moves rearward along the guide holes 14 on the side wall of the conical cavity 13. As the airflow passes through these guide holes 14, it adheres closely to and flows over the front surfaces of each lens 4, effectively removing heat from the lens surface and directly dispersing any condensation that may form on the lens surface. This structure achieves efficient cooling of the LEDs and lens area, ensuring continuous airflow over the lens surface, allowing for timely evaporation or removal of moisture as the airflow passes, thus improving the anti-condensation effect.

[0037] like Figure 2 As shown, in the lens mounting assembly, a fixing plate 3 is further provided between the front cover plate 1 and the base plate 2. The fixing plate 3 has several limiting holes 31 for positioning the lens 4, ensuring the consistency of the beam direction and optical effect after the lens 4 is installed; simultaneously, a second ventilation hole 32 is provided between adjacent limiting holes 31. The second ventilation hole 32 corresponds to the first ventilation hole 22 on the base plate 2, allowing air introduced by the guide hole 14 on the side wall of the front cover plate 1 to smoothly pass through the front cover plate 1, the fixing plate 3, and the base plate 2, forming a complete airflow channel and achieving good heat dissipation and anti-condensation effects. Furthermore, the opening of the conical cavity 13 is precisely aligned with the second ventilation hole 32 on the fixing plate 3, and the edge of the opening of the conical cavity 13 abuts against the surface of the fixing plate 3, preventing the lens 4 from shifting due to lamp vibration or other reasons.

[0038] like Figure 4As shown, in a preferred embodiment, an elastic sealing ring 311 is also provided on the inner wall of the limiting hole 31 of the fixing plate 3. The elastic sealing ring 311 abuts against the outer edge of the lens 4, improving the assembly stability of the lens 4 while preventing moisture, dust and other impurities from seeping into the mounting base 21, enhancing the dustproof and moisture-proof effect of the internal components of the lamp box 100, and ensuring the reliable operation of the lamp under harsh working conditions.

[0039] like Figure 3 As shown, the array of light-transmitting apertures 11 adopts a specific layout, specifically with a central light-transmitting aperture 11 and six fan-shaped light zones 10 surrounding this central aperture, each with a central angle of 60°. Each fan-shaped light zone 10 comprises four layers from the inside out: the first layer has one light-transmitting aperture 11, the second layer has two light-transmitting apertures 11, the third layer has three light-transmitting apertures 11, and the fourth layer has four light-transmitting apertures 11. This design results in a more symmetrical and uniform illumination effect for the beam array, enhancing the overall consistency of the optical output. Correspondingly, the lamp assembly includes 61 20W RGBW four-in-one LED beads, and each LED bead can be controlled in single-color mode.

[0040] Furthermore, the conical cavities 13 within the fan-shaped light area 10 are triangular pyramids, while the conical cavities 13 between two adjacent fan-shaped light areas 10 are square pyramids. This alternating arrangement of triangular and square pyramids further enhances the structural rigidity. Simultaneously, each conical cavity 13 has a guide hole 14 on its side, allowing air to flow rapidly within the conical cavity 13, fully covering the surface of the lens 4 and achieving uniform and efficient heat dissipation and defogging effects.

[0041] like Figure 3 As shown, bolt holes 131 are provided inside the conical cavity 13. The connecting bolts on the base plate 22 can be directly inserted and fixed in the bolt holes 131 to fix the front cover plate 1 from inside the conical cavity 13. After installation, the bolts are hidden inside the conical cavity 13, making the overall lamp structure more compact and saving internal space.

[0042] like Figure 2 As shown, the lamp head front cover 110 and the lamp head rear cover 120 are connected by bolt fixing. The side wall of the front cover plate 1 is provided with several relief grooves 112 for installing bolts along the circumferential direction. These relief grooves 112 facilitate the quick and accurate insertion and installation of bolts. The aforementioned air inlet 111 is provided between adjacent relief grooves 112 to achieve efficient use of space layout.

[0043] In one embodiment, a front windshield 5 is further provided at the front end of the lamp head front cover 110 to protect the lens array from external dust, moisture, or accidental impacts, maintaining the stability and clarity of the light output effect. Preferably, the front windshield 5 is made of electronically atomized glass, i.e., a transparent glass with a built-in electronic atomizing film. When the lamp needs to achieve diffused or uniform light effects during operation, the electronically atomized glass can be powered on by a power source, causing it to quickly switch from a transparent state to a atomized state. In this state, the light diffusion characteristics of the glass surface change, and the light beam scatters when passing through the front windshield 5, making the output light spot softer and more uniform, effectively improving the visual comfort and atmosphere of the stage lighting effects, and meeting the diverse lighting needs of different stage scenarios. Simultaneously, the electronically atomized glass can quickly switch between transparent and atomized states according to actual needs, offering flexible functionality and convenient operation, expanding the application range and performance capabilities of the lamp.

[0044] Although not shown in the figure, it should be understood that a focusing assembly is also provided inside the lightbox 100. The focusing assembly includes a drive motor, a transmission mechanism, and a corresponding guide rail or linear slide rail structure. The lens mounting assembly can move back and forth along the inner axis of the lightbox 100 under the drive of the focusing assembly to change the distance between the lens 4 and the LED beads in the lamp body assembly, thereby adjusting the beam thickness and achieving precise focusing. In the above embodiment, 61 40W RGBW four-in-one LED beads, combined with the focusing assembly, can achieve a focusing range of 4°-60°, meeting various lighting needs from fine beams to wide beams. Through the setting of the above focusing assembly, users can quickly and freely switch between narrow beam focusing and wide beam coloring according to the actual needs of the stage.

[0045] In summary, the moving head light of this utility model, through the above structural design, not only achieves the basic functions of a moving head light, but also further optimizes the lens installation, positioning, heat dissipation, and anti-fog structure. The overall structure is compact, easy to install and maintain, and effectively improves the reliability, light efficiency stability, and adaptability to complex environments of the stage lighting fixture.

[0046] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
