Description

Technical Field

[0001] This utility model relates to the field of LED lens technology, specifically to a focusing LED lens module. Background Technology

[0002] A focused LED lens module is an optical component used in LED lighting systems. It mainly consists of an LED light source and an optical lens. The "lens" are usually precision-designed aspherical or freeform lenses that can concentrate, direct, and optimize the light emitted by the LED to achieve a focused light effect. These modules are commonly used in applications requiring high brightness, long-distance lighting, or specific light spot shapes. The main function of a focused LED lens module is to improve light utilization efficiency and lighting directionality. Specific applications include: flashlights to achieve long-range, focused beams and increase lighting distance; landscape lighting: controlling the size and shape of the light spot to create specific visual effects; providing concentrated, long-distance infrared or white light supplementary lighting for cameras; industrial lighting: used in factories, construction sites, and other places requiring strong light; and plant grow lights: directional illumination of plants to improve light energy utilization. The working principle of a focused LED lens module is based on optical refraction and reflection, with the core being the lens's ability to control light. The specific process is as follows: After the LED chip is powered on, it emits light. The original light is divergent. The light passes through the optical lens in front. The curved design of the lens causes the light to be refracted, "compressing" the originally divergent light and concentrating it into a small angle. After passing through the lens, the light becomes a parallel or small-angle divergent beam, realizing long-distance illumination and a high-brightness central spot. Some modules also have reflector cups installed around the LED to reflect the side light towards the lens, further improving the light-gathering efficiency.

[0003] Common focused LED lens modules typically employ a fixed focal length design or a limited-level adjustment structure, preventing stepless beam adjustment. These modules often fix the lens directly to the bracket or lamp body, making the distance between the light source and the lens unchangeable. Therefore, the beam angle is fixed and can only be set to focused or floodlight mode at the factory, preventing users from flexibly adjusting it according to their needs. Some modules with focusing functions use segmented locking or toggle switch structures, allowing switching between several preset beam patterns. However, the adjustment process has a noticeable stepped feel, and the beam pattern changes discontinuously, failing to accurately match the lighting requirements of different distances and scenes. Furthermore, traditional structures are prone to lens shift, optical axis jitter, or decreased sealing during focusing, affecting the stability of optical performance and the module's durability. These limitations make existing products less adaptable to complex and changing lighting environments, failing to meet users' demands for high-precision, smooth dimming experiences, especially in professional applications requiring precise beam range control. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a focusing LED lens module. By rotating the outer shell, the focusing structure is driven to move the lens sleeve up and down. A limiting component prevents the lens from rotating, enabling continuous variation of the distance between the lens and the LED, and stepless switching between floodlight and focusing. At the same time, the positioning rod and the limiting hole cooperate to ensure that the lens moves only along the axial direction, avoiding optical axis deviation and ensuring beam stability. This solves the problems of common focusing LED modules, which mostly have fixed focal length or level adjustment, cannot change the beam steplessly, and cannot continuously adjust the distance between the lens and the light source, resulting in discontinuous beam switching, inaccurate adjustment, and problems such as optical axis deviation and poor sealing, making it difficult to meet the needs of flexible and stable dimming in complex scenarios.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a focusing LED lens module, including a substrate; and a base disposed on the substrate, wherein a light source assembly for emitting light is disposed on the base; a housing is rotatably connected to the upper end of the substrate, a transparent plastic is fixed to the top of the housing, a light adjustment assembly is disposed inside the housing, and a limit assembly is disposed on the upper part of the base. A lens sleeve is slidably connected to the limiting component. The lens body is installed inside the lens sleeve and is driven by the light adjustment component. When the light adjustment component rotates on the outer shell, it drives the lens sleeve to move up and down along the axis. The limiting component is used to restrict the lens sleeve to rotate synchronously with the light adjustment component, so that the lens sleeve only makes linear motion, thereby adjusting the beam angle formed by the light emitted by the lamp source component through the optical lens inside the lens sleeve.

[0006] Furthermore, the light source assembly includes an adapter slot formed on the upper surface of the base, an adapter mount installed inside the adapter slot, and an LED light source installed on the upper end of the adapter mount.

[0007] Furthermore, the adapter is fixed in the adapter slot by thermally conductive adhesive, and a thermally conductive channel is provided between the adapter and the base to conduct the heat generated by the LED light source during operation to the base.

[0008] Furthermore, the light adjustment assembly includes a threaded inner cylinder disposed inside the housing and a lens sleeve threadedly connected to the threaded inner cylinder.

[0009] Furthermore, the outer wall of the threaded inner cylinder is provided with a helical lead groove, and the outer periphery of the lens sleeve is provided with a guide protrusion that cooperates with the helical lead groove. When the outer shell rotates, the guide protrusion slides along the helical lead groove, driving the lens sleeve to move axially up and down.

[0010] Furthermore, the limiting assembly includes a positioning rod disposed on the upper end of the base, a limiting ring plate disposed on the inner side of the lens sleeve, and a limiting hole opened on the limiting ring plate. There are four positioning rods arranged in a ring, and the limiting holes correspond to the positions of the positioning rods, and there are four limiting holes arranged in a ring.

[0011] Furthermore, the positioning rod and the limiting hole are in a sliding fit, and the wall of the limiting hole and the outer surface of the positioning rod maintain a clearance fit or transition fit to ensure that the lens sleeve maintains stable guidance during the up and down movement.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects: 1. The rotation of the outer shell drives the light adjustment component to move, which in turn drives the lens sleeve to move up and down along the axis. With the help of the limiting component, it prevents the lens body from rotating, so that the distance between the lens body and the LED light source can be continuously adjusted. This enables the stepless transformation of the beam from floodlight to focused light, meeting the lighting needs of different distances and scenarios, and improving the practicality of the product and the user experience. 2. By setting a limiting assembly consisting of a positioning rod, a limiting ring plate, and a limiting hole, the lens sleeve is circumferentially limited, so that it can only move along the axial direction and cannot rotate synchronously with the outer shell and the threaded inner cylinder. This avoids optical axis deviation or optical distortion caused by the rotation of the lens body, and ensures the stability and consistency of the beam output. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1The focusing LED lens module in this embodiment includes a substrate 1; it also includes a base 9 disposed on the substrate 1, and a light source assembly for emitting light is provided on the base 9; a housing 2 is rotatably connected to the upper end of the substrate 1, a transparent plastic 3 is fixed to the top of the housing 2, a light adjustment assembly is provided inside the housing 2, and a limit assembly is provided on the upper part of the base 9.

[0017] In this embodiment, the rotation of the outer shell 2 drives the light adjustment component, which in turn drives the lens sleeve 5 to move up and down. The limiting component prevents it from rotating, thereby achieving continuous adjustment of the distance between the lens and the LED, thus completing the stepless switching between floodlight and focused light. At the same time, the cooperation of the positioning rod 13, the limiting ring plate 6 and the limiting hole 8 ensures that the lens sleeve 5 only moves axially, avoiding optical axis deviation and ensuring stable beam output.

[0018] Please see Figures 1-5 In this embodiment, to enable the lens to move up and down by rotating the outer shell 2, allowing the light to be freely adjusted between illuminating a small area and projecting a long distance, making it more convenient to use, a lens sleeve 5 is slidably connected to the limiting component in this embodiment. The lens body 7 is installed inside the lens sleeve 5 and is driven and cooperated with the light adjustment component. When the light adjustment component rotates the outer shell 2, it drives the lens sleeve 5 to move up and down along the axial direction. The limiting component is used to restrict the lens sleeve 5 to rotate synchronously with the light adjustment component, so that the lens sleeve 5 only makes linear motion, thereby adjusting the beam angle formed by the light emitted by the light source component through the optical lens inside the lens sleeve 5.

[0019] In this embodiment, the substrate 1 supports the overall structure, the base 9 is used to install the lamp source assembly and provide a heat dissipation path, the lamp source assembly is responsible for emitting the original light, the outer shell 2 is rotatable, the transparent plastic 3 serves to protect the interior and allow light to pass through, the light adjustment assembly converts the rotational motion of the outer shell 2 into linear motion, the limiting assembly ensures that the lens sleeve 5 does not rotate during movement, the lens sleeve 5 carries the lens body 7 and realizes up and down movement, the lens body 7 focuses and refracts the light, and by adjusting the distance between the lens and the light source, the beam can be continuously changed from floodlight to focused light to meet the lighting needs of different distances, improve the ease of use and lighting effect, the entire structure realizes the rotary focusing function, the movement is smooth, the position locking is reliable, the optical performance is stable, it is easy to assemble and maintain, and it is suitable for a variety of lighting scenarios that require zoom, improving the practicality of the product and the user experience.

[0020] It should be noted that the light adjustment assembly includes a threaded inner cylinder 4 disposed inside the outer casing 2 and a lens sleeve 5 threadedly connected to the threaded inner cylinder 4. The outer wall of the threaded inner cylinder 4 is provided with a helical guide groove, and the outer periphery of the lens sleeve 5 is provided with a guide protrusion that cooperates with the helical guide groove. When the outer casing 2 rotates, the guide protrusion slides along the helical guide groove, driving the lens sleeve 5 to move axially up and down. The function of the light adjustment assembly is to convert the rotational motion of the outer casing 2 into the linear motion of the lens sleeve 5, thereby realizing the focusing function. The function of the threaded inner cylinder 4 is as part of the transmission structure. Its inner wall is threadedly engaged with the lens sleeve 5, and its outer wall is provided with a helical guide groove to guide the direction of movement. The function of the helical guide groove is to provide a sliding path for the guide protrusion. The rotational motion is converted into axial displacement through the helical angle. The function of the lens sleeve 5 is to support the lens body 7 and move axially up and down under the action of external force, changing the distance between the lens and the light source. The function of the guide protrusion is to be embedded in the helical guide groove and slide along the groove as the outer casing 2 rotates, pushing the lens sleeve 5 to complete the lifting and lowering action.

[0021] Please see Figures 1-5 In this embodiment, to ensure that the lens sleeve 5 can only slide up and down without rotating, preventing the light from being skewed and providing a more stable and accurate illumination, the limiting component in this embodiment includes a positioning rod 13 disposed on the upper end of the base 9, a limiting ring plate 6 disposed on the inner side of the lens sleeve 5, and a limiting hole 8 opened on the limiting ring plate 6. There are four positioning rods 13 arranged in a ring, and the limiting holes 8 are arranged in a ring corresponding to the positions of the positioning rods 13. The positioning rods 13 and the limiting holes 8 are in a sliding fit, and the hole wall of the limiting hole 8 maintains a clearance fit or transition fit with the outer surface of the positioning rod 13 to ensure that the lens sleeve 5 maintains stable guidance during the up and down movement.

[0022] In this embodiment, the function of the limiting component is to constrain the movement of the lens sleeve 5, so that it can only slide up and down and cannot rotate with the outer shell 2, thereby ensuring the stability of the optical axis and preventing light deviation. The function of the positioning rod 13 is to serve as a guide reference, restrict the rotational freedom of the lens sleeve 5, and provide stable linear motion guidance. The function of the limiting ring plate 6 is to be fixed inside the lens sleeve 5, serving as a cooperating component of the limiting structure, bearing the limiting hole 8, and participating in the anti-rotation function. The function of the limiting hole 8 is to cooperate with the positioning rod 13, allowing it to slide within the hole, and achieving axial movement while preventing circumferential rotation through clearance or transition fit.

[0023] It should be noted that the light source assembly includes an adapter groove 10 formed on the upper surface of the base 9, an adapter seat 11 installed inside the adapter groove 10, and an LED light source 12 installed on the upper end of the adapter seat 11. The adapter seat 11 is fixed in the adapter groove 10 by thermally conductive adhesive, and a thermally conductive channel is provided between the adapter seat 11 and the base 9 to conduct the heat generated by the LED light source 12 when it is working to the base 9.

[0024] The working principle of the above embodiments is as follows: In use, when the user starts to rotate the outer shell 2, the outer shell 2 drives the inner threaded cylinder 4 to rotate synchronously. The spiral lead groove on the outer wall of the inner threaded cylinder 4 rotates accordingly, pushing the guide protrusion on the outer periphery of the lens sleeve 5 to slide along the groove. Since the guide protrusion cooperates with the spiral lead groove, the rotational motion is converted into the axial up and down movement of the lens sleeve 5. At this time, the limiting component plays a role. The positioning rod 13 and the limiting hole 8 maintain a sliding fit, restricting the lens sleeve 5 from rotating, so that it can only move in a straight line. The lens sleeve 5 drives the inner lens body 7 to move closer to or away from the LED light source 12, changing the focusing distance of the light through the lens. When the lens is close to the light source, it forms floodlight, and when it is far away, it forms focused light, realizing continuous adjustment of the beam angle. At the same time, the heat generated by the LED light source 12 is conducted to the base 9 through the adapter 11 via thermally conductive adhesive, and then diffused by the base 9 and the substrate 1, ensuring stable operation of the module. The transparent plastic 3 always seals the front end to protect the internal structure, ultimately realizing the functions of rotary focusing, variable beam, stable lighting, and convenient use.

The control circuit of the controller can be implemented by those skilled in the art through simple programming. The power supply is also common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail here.
