Description

Technical Field

[0001] This utility model relates to the field of optical lens technology, and specifically to an optical lens structure for multiple light sources. Background Technology

[0002] Spotlights are a type of high-efficiency lighting fixture. Their design principle involves using lenses to reflect or refract light sources into a small area, creating a strong and focused beam. Due to their high brightness and high contrast, these lights are widely used both indoors and outdoors.

[0003] For example, Chinese patent document CN222142827U discloses a multi-angle rotating adjustment lens, including a cover plate. Three first optical cups, three second optical cups, and three third optical cups are fixedly connected to the back of the cover plate. A 20-degree lens is fixedly connected inside the first optical cup, a 40-degree lens is fixedly connected inside the second optical cup, and a 60-degree lens is fixedly connected inside the third optical cup. Three supporting arc plates are fixedly connected to the back of the cover plate, and mounting rings are rotatably connected to the outside of the three supporting arc plates. Three light-expanding plates are fixedly connected to the front of the cover plate, and the three light-expanding plates correspond to the three third optical cups respectively.

[0004] In the above technical solution, the positions of the three first, second, and third light cups can be adjusted by rotating the cover plate so that the three light sources can be captured in the first, second, or third light cup. The size of the light spot can be adjusted by using lenses at different angles in the first, second, and third light cups.

[0005] However, in actual use, it was found that in order to prevent the cover from moving accidentally, a spring pin was added to lock the cover by inserting the spring pin into the corresponding hole. Therefore, when rotating the cover, the spring pin must be pulled out first, and after adjustment, the spring pin must be reinserted. Therefore, there is some inconvenience when adjusting the size of the light spot. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an optical lens structure for multiple light sources, which can make the adjustment of the light spot size more convenient and quick.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an optical lens structure for multiple light sources, comprising a cover plate, on one side surface of which three sets of optical units are fixedly arranged circumferentially, the three sets of optical units including a first optical cup, a second optical cup, and a third optical cup; a detachable mounting ring is provided on the side of the cover plate where the optical units are located, and a mounting seat is provided on the outer periphery of the mounting ring; the mounting seat is connected to the lamp holder of the light source; the mounting seat is provided with three sets of through light inlets, which are used for direct passage of the light source to be aligned with different optical cups to adjust the size of the light spot; a radial pressure unit is connected between the mounting seat and the mounting ring, the radial pressure unit being used to apply damping when the cover plate rotates to prevent the cover plate from moving accidentally.

[0008] The present invention is further configured such that: the radial pressure unit includes a steel ball; the inner wall of the mounting base is provided with a mounting groove recessed toward the center; a spring is provided in the mounting groove; one end of the spring is fixed to the bottom of the mounting groove and the other end is fixed to the steel ball; the outer wall of the mounting ring is provided with an arc groove recessed toward the center; there are multiple arc grooves evenly distributed around the circumference; and the steel ball can be coupled into each arc groove.

[0009] The present invention is further configured such that: a 20-degree lens is fixedly connected inside the first optical cup, a 40-degree lens is fixedly connected inside the second optical cup, and a 60-degree lens is fixedly connected inside the third optical cup.

[0010] The present invention is further configured such that: the cover plate is provided with a buckle on the side where the optical unit is located, the buckle is multiple and evenly distributed around the circumference, the mounting ring circumferential wall is provided with a through groove, the groove corresponds to the buckle, and the buckle can be snapped into the groove to form a limiting fit between the two.

[0011] The present invention is further configured such that the outer periphery of the cover plate is provided with stripes for increasing friction.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] Because a radial pressure unit is installed in the mounting base, after the cover plate and mounting ring are connected and embedded in the mounting base, when it is necessary to adjust the relative position between the optical unit and the light inlet by rotating the cover plate, the radial pressure unit can apply radial pressure to the mounting ring to generate damping when the cover plate rotates, thereby preventing the cover plate from moving accidentally. When the cover plate needs to be rotated, the rotational force applied to the cover plate only needs to be greater than the resistance generated by the radial pressure unit to rotate the cover plate normally. Compared with the existing technology of limiting the position by inserting a spring pin, this solution can prevent the cover plate from moving accidentally to a certain extent, and can make it faster and more convenient to rotate the cover plate when needed.

[0017] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are used only for the convenience of describing the invention and for 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 the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] like Figures 1 to 3 As shown, this utility model discloses an optical lens structure for multiple light sources, including a cover plate 1, which is a circular, colorless, transparent glass. Three sets of optical units 2, evenly distributed circumferentially, are fixed to one side of the cover plate 1. These three sets of optical units 2 include a first light cup 21, a second light cup 22, and a third light cup 23. The cover plate 1 is connected to a mounting base 4 on the side where the optical units 2 are located via a detachable mounting ring 3. The mounting base 4 is used to fix the light to the lamp holder of an external light source. The mounting base 4 has three through-holes 41, the positions of which correspond to the optical axes of each light cup. By rotating the cover plate 1, different light cups can be aligned with the light inlets 41, thereby adjusting the size of the light spot projected by the light source. A 20-degree lens is fixed inside the first light cup 21 for narrow-angle focusing to form a small light spot; a 40-degree lens is fixed inside the second light cup 22 to provide a light spot with a medium scattering range; and a 60-degree lens is fixed inside the third light cup 23 to achieve a wide-angle illumination effect. After the light emitted by the light source enters the corresponding light cup through the light inlet 41, it is refracted by the internal lens at a preset angle. The user can switch between different light cups and quickly adjust the light spot size by rotating the cover plate 1.

[0020] To ensure the stability of the cover plate 1 during rotation, and to prevent it from malfunctioning under slight force, a radial pressure unit is provided between the mounting base 4 and the mounting ring 3. When it is necessary to adjust the relative position between the optical unit 2 and the light inlet 41 by rotating the cover plate 1, the radial pressure unit applies radial pressure to the mounting ring 3 to generate damping when the cover plate 1 rotates, thereby preventing malfunction. When the cover plate 1 needs to be rotated, the applied rotational force needs to be greater than the resistance generated by the radial pressure unit for the cover plate 1 to rotate normally. Compared with the existing technology that uses spring 52 and pin insertion for limiting, this solution can prevent malfunction of the cover plate 1 while making the rotation of the cover plate 1 faster and more convenient.

[0021] In this embodiment, the radial pressure unit includes a steel ball 51. The inner wall of the mounting base 4 has a mounting groove 42 recessed towards the center. A spring 52 is installed in the mounting groove 42, with one end fixed to the bottom of the groove and the other end pressing against and fixing the steel ball 51. The outer wall of the mounting ring 3 has multiple concave arc grooves 31, evenly distributed around the circumference. When the cover plate 1 rotates, the steel ball 51 is embedded in different arc grooves 31 under the elastic force of the spring 52, forming a staged damping feedback to prevent the cover plate 1 from shifting due to accidental contact or vibration, ensuring precise alignment of different light cups with the light inlet 41. In addition, the outer circumferential surface of the cover plate 1 is provided with anti-slip stripes 7, such as wavy patterns or raised structures, to increase the friction during user rotation and facilitate one-handed adjustment.

[0022] In this embodiment, the cover plate 1 and the mounting ring 3 are detachably connected by a snap-fit ​​structure 6, which facilitates overall assembly. Specifically, the cover plate 1 has multiple snap-fits 6 evenly distributed circumferentially on one side where the optical unit 2 is located, and the mounting ring 3 has a corresponding through slot 32 on its peripheral wall. During installation, the snap-fits 6 are directly snapped into the slot 32 to form an axial limit, fixing the cover plate 1 and the mounting ring 3; during disassembly, simply press the snap-fits 6 to disengage them from the slot 32 to separate the cover plate 1 and the mounting ring 3, facilitating cleaning of the interior of each optical cup or replacement of lenses with different angles.

[0023] In actual operation, the user first fixes the mounting base 4 to the lamp holder and aligns the light source with a light inlet 41. When rotating the cover plate 1, the engagement of the steel ball 51 and the arc groove 31 produces a "click" tactile feedback, enhancing the feel of rotating the cover plate 1. For example, when wide-angle lighting is needed, the third reflector 23 is rotated to align with the light inlet 41, at which point the 60-degree lens diffuses the light over a wider area; if a focused effect is needed, the first reflector 21 is switched to concentrate the light through the 20-degree lens. Through the above structure, the present invention achieves rapid adjustment of the light spot size, and the damping design improves operating accuracy and enhances the operating feel.

[0024] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
