Description

Technical Field

[0001] The utility model relates to the technical field of lighting equipment, in particular to an electric focusing component and a lamp. Background Art

[0002] Spotlights are a type of lighting fixture that can be used to create an indoor lighting atmosphere. If a row of small spotlights are combined, the light can change into wonderful patterns. Since the small spotlights can be freely changed in angle, the combined lighting effect is also ever-changing. Spotlights can also be used for local lighting to create an atmosphere.

[0003] Indoor spotlights currently on the market are generally installed after the focal length is adjusted or manually adjusted after installation. Manual adjustment usually relies on human perception and feel, and it is difficult to achieve precise adjustment effects. Manual adjustment may be difficult for spotlights installed at high places or difficult to reach. In situations where the focal length of the spotlight needs to be adjusted frequently, the convenience of manual adjustment will be greatly reduced. If the user operates improperly or uses excessive force, the adjustment mechanism may be damaged, affecting the service life of the spotlight. During use, if the adjustment mechanism is not set reasonably or the operation is not user-friendly, it may also affect the user experience. Utility Model Content

[0027] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0029] In the present application, the directions or positional relationships indicated by the terms "upper", "lower", "inner", "middle", "outer", "front", "back", etc. are based on the directions or positional relationships shown in the drawings. These terms are mainly used to better describe the present application and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific direction, or to be constructed and operated in a specific direction.

[0030] In addition, some of the above terms may be used to express other meanings in addition to indicating orientation or positional relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in this application can be understood according to specific circumstances.

[0031] The utility model provides an electric focusing assembly and a lamp, which can accurately control the movement of a lens module between a first position and a second position through a driving member and a connecting member in a driving module, thereby achieving accurate focusing. Due to the adoption of an electric drive method, the assembly can quickly respond to instructions issued by the control module, thereby quickly adjusting the position of the lens module and achieving rapid zooming. The electrical connection between the control module and the driving module allows the focusing operation to be performed through electronic signals, which is easy to achieve remote control and automatic control. This facilitates the integration and intelligence of the equipment. Since the lens module is fixed in the installation space and is stably driven by the driving module through the connecting member, the entire focusing assembly has good stability. Even under continuous use or high-load working conditions, stable performance can be maintained. Example

[0032] The utility model embodiment provides an electric focusing assembly, such as Figures 1 to 3 As shown, it includes a shell 1, an installation space 11 is provided inside the shell 1, and an opening 12 is provided at one end of the shell 1; a lens module 2, the lens module 2 is provided in the installation space 11, the lens module 2 includes a first position and a second position, the first position is close to the opening 12, and the first position is far away from the opening 12; a driving module 3, the driving module 3 includes a driving member 31 and a connecting member 32, the driving module 3 is connected to the lens module 2 through the connecting member 32, and the driving member 31 is used to drive the lens module 2 to move between the first position and the second position; a control module, the control module is electrically connected to the driving module 3.

[0033] like Figure 2As shown, more specifically, the lens module 2 includes a zoom lens 21 and a lens housing 22. Among them, the zoom lens 21 can be of various types, such as a liquid zoom lens 21, a microlens or a microlens array, and a flexible zoom lens 21. These types of zoom lenses 21 have their own characteristics. For example, the liquid zoom lens 21 has the advantages of fast response time and not easily damaged by external forces; the flexible zoom lens 21 has the advantages of compact structure and flexible control. The zoom lens 21 is the core part of the lens module 2, which adjusts the focal length by changing its own shape or position. For the liquid zoom lens 21, its zoom is achieved by changing the shape of the liquid; for the flexible zoom lens 21, the focal length is adjusted by changing the deformation degree of the transparent elastic film. The lens housing 22 is an important part to protect the zoom lens 21. It provides a stable installation environment to ensure that the zoom lens 21 can work normally. At the same time, the lens housing 22 also has certain dustproof and waterproof functions to protect the internal components from the influence of the external environment. The selection of the lens housing 22 can consider multiple factors, such as material selection, structural strength, heat dissipation performance, etc. In terms of material selection, light and strong materials such as aluminum alloy or high-strength plastic can be selected; in terms of structural strength, it is generally necessary to ensure that the lens housing 22 can withstand certain external forces and impacts; in terms of heat dissipation performance, a reasonable heat dissipation structure can be considered to ensure that the internal components will not overheat during long-term operation. When the zoom lens 21 and the lens housing 22 are used in combination, a complete lens module 2 can be formed. Through the action of the drive module 3 and the control module of the electric focusing assembly, the zoom lens 21 can be accurately controlled to move between the first position and the second position, thereby realizing a precise focusing function. This integrated structure enables the lamp to flexibly adjust the focal length according to different lighting requirements and environmental changes, thereby improving the applicability and practicality of the lamp.

[0034] like Figure 2As shown, more specifically, the lens housing 22 includes a containing space 221, and the connecting member 32 can move in the containing space 221. The connecting member 32 is an important component connecting the driving module 3 and the lens module 2. When the connecting member 32 is connected, it can move in the containing space 221 of the lens housing 22. The structure of the connecting member 32 needs to take into account the connection mode between the driving module 3 and the lens module 2, as well as the matching relationship with the wall surface of the containing space 221, so as to ensure that the lens module 2 can be driven to move stably and reliably. The material of the connecting member 32 is usually selected from high-strength, low-friction coefficient materials, such as stainless steel or polymer plastics, etc., to improve its durability and service life. In the containing space 221 of the lens housing 22, the connecting member 32 and the lens module 2 are fixed together by some form of connection mechanism such as screws, screws, worms, buckles, etc. When the driving module 3 receives the instruction of the control module, the driving member 31 will drive the connecting member 32 to move in the containing space 221, thereby driving the lens module 2 to focus.

[0035] like Figure 2 and Figure 3 As shown, a guide member 4 may also be included, and the guide member 4 is arranged in the installation space 11. More specifically, the guide member 4 is threadedly connected to the lens housing 22.

[0036] like Figure 2 and Figure 3 As shown, a plurality of guide members 4 may be provided in the installation space 11. More specifically, the connecting member 32 may be a worm, and a thread adapted to the connecting member 32 is provided in the accommodating space 221.

[0037] In the electric focus assembly, the introduction of the guide member 4 can further improve the accuracy and stability of the movement of the lens module 2. The guide member 4 can be used to ensure the stability and linearity of the lens module 2 during the movement, and prevent the lens module 2 from offsetting or shaking during the movement. The guide member 4 is arranged in the internal installation space 11 of the housing 1, and cooperates with the lens housing 22 and the connecting member 32. The guide member 4 is connected to the lens housing 22 by a thread. This connection method can provide a stable connection while allowing the lens module 2 to move accurately in a straight line along the guide member 4.

[0038] The connecting member 32 is a worm. A worm is a rod-shaped component with threads, which can achieve linear motion by cooperating with a threaded hole. A thread that matches the connecting member 32 is provided in the accommodating space 221. In this way, when the driving member 31, such as a motor, rotates the worm, the worm can move accurately in a straight line along the thread, thereby driving the lens module 2 to focus. A plurality of guide members 4 can be provided in the installation space 11. These guide members 4 can be distributed on both sides or around the lens module 2 to ensure that the lens module 2 is evenly supported and guided when moving. The layout of the guide members 4 can take into account factors such as the size, weight and movement trajectory of the lens module 2. Reasonable layout can ensure the stability and accuracy of the lens module 2 during movement.

[0039] Through the threaded connection between the guide member 4 and the lens housing 22 and the matching between the connector 32 and the inner thread of the accommodating space 221, the accuracy of the lens module 2 during movement can be ensured and the focusing accuracy can be improved. The structure of multiple guide members 4 can ensure that the lens module 2 is evenly supported and guided during movement, prevent deviation or shaking, and improve the stability of the system. The threaded connection and the matching thread structure can provide a stable connection and precise movement control, ensure the reliability and durability of the system, and prevent the lens from idling.

[0040] The number of the guide members 4 can be multiple, where multiple means two or more than two. Figure 3 As shown, when the number of guide members 4 is two, more specifically, two guide members 4 are connected to the lens housing 22, so that the two guide members 4 and the connecting member 32 or the accommodating space 221 form a triangle on the lens housing 22. Among them, the largest internal angle of the triangle does not exceed 90°. Such a structure can make the driving module 3 more stable when driving the lens module 2 to move, reduce unnecessary shaking or tilting, and the force on each component is more even, thereby avoiding structural damage or performance degradation caused by uneven force.

[0041] An electric focusing assembly provided by the embodiment of the utility model may also include a receiving module, which is electrically connected to the control module. By setting the receiving module, remote control or remote control for electric focusing can be achieved. By adding the receiving module, the electric focusing assembly can realize remote control or remote control functions, providing users with a more flexible and convenient operation method. This can not only improve the use efficiency of the device, but also bring better user experience to the user. The main function of the receiving module is to communicate with an external control device (such as a remote control, a smart phone, a tablet computer, etc.), receive control instructions and pass them to the control module, and then control the movement of the lens module 2 and the adjustment of the focal length. The receiving module can choose to be compatible with a variety of communication protocols and interfaces to communicate with an external control device. For example, it can support wireless communication protocols such as Bluetooth, Wi-Fi, infrared, or connect to an external device through a wired interface. The receiving module can have a strong signal receiving capability to ensure that the control instructions can be stably received in a complex environment. This can be achieved by adopting a high-performance antenna, optimizing the receiving algorithm, etc. The receiving module can be able to parse the received control instructions and convert them into signals that the control module can understand. This usually involves processes such as data decoding and protocol conversion. The receiving module and the control module communicate with each other through an electrical connection. This connection can be a direct wire connection or a connection through a circuit on a circuit board. Once the receiving module receives and parses the control instruction, it sends the instruction to the control module, and the control module controls the driving module 3 to drive the lens module 2 to focus according to the instruction.

[0042] like Figure 1 As shown, more specifically, the housing 1 may be a cylinder or other shapes. The cylindrical structure has good stability and can withstand forces from all directions without being easily deformed. This stability is important for protecting the precision lens module 2 and the electric focusing mechanism inside. The cylindrical structure can maximize the use of space, making the assembly more compact while maintaining functional integrity. This is particularly important for electric focusing assemblies that need to be installed in equipment with limited space. The cylindrical housing 1 usually has a smooth surface and a standard mounting interface (such as threaded holes, card slots, etc.), which is convenient for users to install and fix. In addition, the cylindrical structure can also be seamlessly connected with other cylindrical devices or components to improve the integration of the overall system. The cylindrical housing 1 can improve the heat dissipation performance of the assembly through a reasonable heat dissipation structure (such as heat dissipation holes, heat sinks, etc.). This is of great significance for maintaining a stable operating temperature of internal electronic components and extending the service life of the assembly. Therefore, choosing a cylinder as the housing 1 structural scheme of the electric focusing assembly can not only improve the structural stability and compactness of the assembly, but also improve the heat dissipation performance, facilitate installation and fixation, and have good aesthetics.

[0043] Compared with the prior art, the electric focusing assembly provided by the embodiment of the utility model can accurately control the movement of the lens module between the first position and the second position through the driving member and the connecting member in the driving module, thereby achieving precise focusing. Due to the adoption of the electric drive mode, the assembly can quickly respond to the instructions issued by the control module, thereby quickly adjusting the position of the lens module and achieving rapid zooming. The electrical connection between the control module and the driving module allows the focusing operation to be performed through electronic signals, which is easy to achieve remote control and automatic control. This facilitates the integration and intelligence of the equipment. Since the lens module is fixed in the installation space and is stably driven by the driving module through the connecting member, the entire focusing assembly has good stability. Even under continuous use or high-load working conditions, stable performance can be maintained. Example

[0044] The utility model also provides a lamp, such as Figures 1 to 3 As shown, it includes any electric focusing assembly in Embodiment 1. Wherein, the lamp may be an indoor spotlight.

[0045] Compared with the prior art, the lamp provided by the embodiment of the utility model realizes precise adjustment of the focal length of the lamp by providing such an electric focusing assembly and precisely controlling the movement of the lens module between the first position and the second position. Such precision can ensure that the size and shape of the light spot are precisely controlled to meet different lighting requirements.

[0046] In situations where lighting scenes need to be quickly switched or lighting effects need to be adjusted, such as exhibitions and performances, the fast-response electric focus component will greatly improve the practicality and convenience of the lamp. The electrical connection between the control module and the drive module allows the focus operation to be performed through electronic signals, making it easy to achieve remote control and automatic control. This control method provides convenience for the intelligent control of lamps.

[0047] Combined with the intelligent analysis system, the electric focusing component can realize real-time analysis and processing of monitoring images, further improving the response speed and accuracy of the monitoring system.

[0048] The above are only preferred specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
