Description

Technical Field

[0001] This application relates to the technical field of lighting equipment, and in particular to a novel LED zoom spotlight. Background Technology

[0002] A spotlight is a projection lighting fixture that uses high-power LEDs as its light source and mixes three primary colors to create different colors. It is synchronized with an intelligent controller and can be connected to a control console.

[0003] Traditional LED spotlights still have shortcomings. The high heat generated by high-power LEDs during operation is easily conducted through the lamp panel to the optical components, leading to accelerated light decay and shortened lifespan. Existing heat dissipation solutions have low heat transfer efficiency and unreasonable airflow design, making it difficult to achieve rapid and uniform heat dissipation, especially in high-intensity continuous lighting scenarios where insufficient heat dissipation is particularly prominent. Conventional zoom structures rely on replacing lenses or complex gear sets, requiring interruption of lighting during adjustment and failing to achieve stepless zoom. Mechanical sliding mechanisms are prone to jamming due to thermal expansion and lack modular design, resulting in difficult maintenance and limited applicability. In addition, the compact internal space of spotlights means that thermal interference between the heat dissipation module and optical components reduces zoom accuracy, while traditional fixed installation methods further limit the coordinated optimization of heat dissipation and light path adjustment.

[0004] Therefore, there is an urgent need for an innovative structure that integrates efficient active heat dissipation and mechanical stepless zoom to meet the stringent requirements of stage, film and television and other professional fields for precise control of light spots and equipment stability. Utility Model Content

[0005] In order to solve the problems mentioned in the background art, this application provides a novel LED zoom spotlight.

[0006] This application provides a novel LED zoom spotlight, which adopts the following technical solution:

[0007] Optionally, the housing lamp cup ring is provided with a zoom lens inside, a lamp panel is provided below the zoom lens, a lamp plate is movably connected below the lamp panel, a lamp plate heat sink is provided below the lamp plate, an internal thread nut is provided on the outside of the lamp plate heat sink, and a lamp cup ring bracket is movably sleeved on the outside of the internal thread nut.

[0008] Optionally, a heat dissipation copper pipe is movably sleeved inside the lamp cup ring bracket, a heat dissipation fan is provided on one side of the heat dissipation copper pipe, and a heat extraction fan is provided above the heat dissipation fan.

[0009] Optionally, a heat sink aluminum plate is movably mounted above the heat-generating fan.

[0010] Optionally, the lamp cup ring bracket and the outer lamp cup ring are connected by a threaded structure to achieve overall fixation.

[0011] Optionally, the heat-generating fan and the cooling fan are arranged vertically to form a bidirectional heat dissipation air duct.

[0012] Optionally, a thermally conductive silicone grease layer is filled between the heat dissipation aluminum fins of the lamp panel and the lamp panel to increase heat transfer.

[0013] Optionally, the internal thread nut has upwardly sloping grooves on both sides, allowing the lamp cup ring bracket to move up and down.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] 1. A bidirectional vertical airflow system, combined with heat dissipation copper pipes and a thermally conductive silicone grease layer, forms a highly efficient active cooling system. This system rapidly dissipates heat generated by high-power LEDs, effectively suppressing light decay and extending the lifespan of the luminaire, making it suitable for high-intensity continuous lighting scenarios. The modular layout decouples the heat dissipation components from the optical components, reducing heat transfer interference with the optical path. Simultaneously, threaded connections and movable sleeve structures enhance maintainability.

[0016] 2. The unique mechanical stepless zoom mechanism drives the lamp cup ring bracket to slide up and down via an internal threaded nut with an oblique sliding groove, achieving continuous focus adjustment without interrupting lighting or changing lenses. It is convenient and highly precise. The movable copper heat dissipation pipe avoids jamming and ensures smooth zooming. In summary, this design overcomes the pain points of traditional spotlights, such as low heat dissipation efficiency, inflexible zooming, and significant thermal interference, meeting the stringent requirements of stage, film, and other professional fields for precise spotlight control, equipment stability, and long-term reliability.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses a novel LED zoom spotlight. For example... Figure 1-5 As shown, a novel LED zoom spotlight includes a housing lamp cup ring 1, inside which a zoom lens 2 is disposed. The housing lamp cup ring 1 provides a stable mounting space for the zoom lens 2, ensuring the accuracy of the optical path. Below the zoom lens 2, there is a lamp panel 3. Below the lamp panel 3, there is a lamp board 4 movably connected. Below the lamp board 4, there is a lamp board heat sink aluminum sheet 5. A thermally conductive silicone grease layer is filled between the lamp board heat sink aluminum sheet 5 and the lamp board 4 to increase heat transfer. By filling the microscopic gaps at the contact surface between the two, the heat conduction efficiency between the interfaces is significantly improved, thereby quickly transferring the heat generated by the high-power LED during operation from the lamp board 4 to the heat sink aluminum sheet, thereby reducing the core temperature of the LED, effectively suppressing light decay and extending the service life of the lamp.

[0025] Please see Figure 1-4 The lamp plate heat sink aluminum fin 5 has an internal thread nut 6 on its outer side. The internal thread nut 6 has upward-sloping sliding grooves on both sides. Through a mechanical sliding structure, the rotational motion is converted into vertical displacement, allowing the lamp cup ring bracket 7 to move up and down. This continuously adjusts the distance between the lamp plate 4 and the zoom lens 2, achieving a stepless zoom function that does not require interruption of lighting and is easy to operate.

[0026] Please see Figure 1-4 The lamp cup ring bracket 7 is movably sleeved on the outside of the internal thread nut 6. The inclined sliding groove of the internal thread nut 6 and the lamp cup ring bracket 7 form a mechanical transmission mechanism, which converts the rotational motion into vertical displacement, driving the distance between the lamp plate 4 and the zoom lens 2 to change continuously, realizing stepless focusing. The lamp cup ring bracket 7 is fixed to the outer lamp cup ring 1 by threads, ensuring the coordinated movement of the optical components and the heat dissipation module during focusing, avoiding light path deviation caused by thermal interference. The focal length of the light is changed by adjusting the distance between the zoom lens 2 and the lamp plate panel 3. A heat dissipation copper pipe 10 is movably sleeved inside the lamp cup ring bracket 7, and a heat dissipation fan 9 is provided on one side of the heat dissipation copper pipe 10.

[0027] Please see Figure 5Above the heating fan 8, a heat sink 5 for the LED panel is movably installed. The heat sink 5 is in close contact with the LED panel 4 and efficiently dissipates heat from the LED through a thermally conductive silicone grease layer. The heat accumulated on the heat sink 5 is actively guided by forced airflow. The heating fan 8 is located directly below the heat sink 5, forming a bottom-up directional airflow that quickly removes the heat generated by the LED panel 4 absorbed by the heat sink 4. Together with the vertically set cooling fan 9, it forms an efficient bidirectional heat dissipation channel, significantly improving heat transfer efficiency, reducing heat interference to the optical components above, ensuring zoom accuracy, and extending the life of the lamp. The heating fan 8 and the cooling fan 9 are set vertically. The heating fan 8 actively draws out the high-temperature airflow accumulated in the area of ​​the LED panel 4 and quickly directs the heat to the heat dissipation copper pipe 10 and the surrounding heat dissipation module, achieving efficient and coordinated heat dissipation through forced convection. The cooling fan 9, on the other hand, discharges the heated air laterally, achieving directional separation of hot and cold airflow. This vertical bidirectional air duct significantly improves heat exchange efficiency, avoids the eddy current retention problem of traditional unidirectional air ducts, and ensures that the heat generated by high-power LEDs is continuously and evenly discharged to the outside of the lamp, thereby effectively suppressing light decay, extending component life, and ensuring equipment stability under high-intensity continuous lighting.

[0028] Please see Figure 1-4 The lamp cup ring bracket 7 serves as a connecting hub, supporting both the heat dissipation copper pipe 10 and the heat dissipation fan 9. It is also fixed to the outer lamp cup ring 1 via threads, achieving physical separation between the heat dissipation module and the optical module, thus avoiding direct interference of heat conduction with the optical path. The lamp cup ring bracket 7 and the outer lamp cup ring 1 are connected by a threaded structure to achieve overall fixation. The threaded connection provides rigid support and overall stability for the entire spotlight assembly, ensuring that the relative position of the optical component and the heat dissipation structure remains fixed during zooming. At the same time, it provides a reliable motion basis for the up-and-down sliding zooming mechanism driven by the inclined groove of the internal thread nut 6, avoiding structural loosening or thermal interference caused by mechanical displacement.

[0029] The implementation principle of a novel LED zoom spotlight according to an embodiment of this application is as follows: A front-drive assembly body is formed by a housing lamp cup ring 1, a lamp cup ring bracket 7, and a zoom lens 2. A fixed assembly body is formed by an internal thread nut 6, a lamp plate heat sink 5, a lamp plate 4, and a lamp plate panel 3. When the fixed assembly body is fixed, rotating the front-drive assembly body causes the support protrusions on the lamp cup ring bracket 7 to slide up and down along the oblique grooves on both sides of the internal thread nut 6, driving the distance between the lamp plate 4 and the zoom lens 2 to change continuously, achieving stepless zoom.

[0030] A heat sink 5 for the LED panel is movably mounted above the heating fan 8. The two work together through forced airflow: the heating fan 8 actively draws in the high-temperature airflow from the LED panel 4 area and directs it to the heat dissipation copper pipe 10, while the cooling fan 9 laterally discharges the accumulated heat, forming a vertical bidirectional heat dissipation channel that significantly improves heat exchange efficiency. A layer of thermally conductive silicone grease is filled between the heat sink 5 and the LED panel 4 to fill the microscopic gaps at the contact surface, enhancing heat transfer efficiency and quickly dissipating LED heat. The lamp cup ring bracket 7 is connected to the outer casing lamp cup ring 1 via a threaded structure, providing rigid support for the entire structure and ensuring the stability of the optical and heat dissipation components during zooming, preventing structural loosening or thermal interference caused by mechanical displacement.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
