Description

Technical Field

[0001] This utility model relates to the field of pattern beam lamp technology, and in particular to a cut-in pattern magnification optical structure for pattern beam lamps. Background Technology

[0002] Traditional pattern beam lights typically employ a fixed optical path structure, with basic components including a pattern plate, a focusing lens assembly, and a light-emitting lens. They magnify the pattern primarily by using a motor to drive the focusing lens assembly back and forth along the optical axis, changing its relative distance to the pattern plate, thereby achieving magnification, reduction, and focusing. The disadvantage of this method is that: Continuous magnification but slow speed: The motor-driven focusing lens group takes a certain amount of time to move, making it impossible to achieve "instant" switching of pattern size, which is difficult to meet the needs of some occasions that require fast zoom effects.

[0003] Long structural travel: In order to achieve a large magnification change, the focusing lens group needs a large travel, which results in a long overall size of the lamp and is not conducive to compact structural design.

[0004] Limited functionality: Conventional focusing structures change sharpness during magnification, requiring the focus to be completed before a clear image can be obtained again, thus limiting dynamic performance.

[0005] Conventional lighting fixtures use a combination of three lens groups: a light-emitting lens, a focusing lens, and a magnifying lens. The magnification is achieved by combining the magnifying and focusing lenses. However, this method cannot quickly switch between "normal mode" and "magnification mode", lacks flexibility, and cannot achieve fast, instantaneous, and high-precision pattern magnification.

[0006] Therefore, there is an urgent need in the field for an optical system structure that can overcome the above-mentioned shortcomings and achieve fast, instantaneous, and high-precision pattern magnification switching. Utility Model Content

[0007] This invention proposes a cut-in pattern magnification optical structure for pattern beam lamps to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: An in-line pattern magnification optical structure for a pattern beam lamp includes a light source, a pattern disk mounted above the light source, a magnifying lens module mounted above the pattern disk, a focusing lens module mounted above the magnifying lens module, and a light-emitting lens module mounted above the focusing lens module. The magnifying lens module includes a driving component, a transmission mechanism fixedly connected to the output end of the driving component, a bracket fixedly connected to one end of the transmission mechanism, and a magnifying lens fixedly mounted on the upper end of the bracket.

[0009] Preferably, the focusing lens module can move back and forth along the optical axis.

[0010] Preferably, the transmission mechanism is a linkage mechanism.

[0011] Preferably, the magnifying lens is a biconvex lens or a plano-convex lens, or the magnifying lens is a cemented lens assembly, consisting of at least two lenses cemented together.

[0012] Preferably, a mounting groove is fixedly formed on the disc of the bracket, and a through hole is fixedly formed at the lower end of the mounting groove.

[0013] Preferably, multiple sets of screw holes are provided on the outer side of the perforation, and the multiple sets of screw holes are installed at equal intervals on the mounting groove. A mounting plate is installed at the upper end of the mounting groove, and multiple sets of fixing bolts are installed on the mounting plate. The multiple sets of fixing bolts are respectively threaded inside the multiple sets of screw holes.

[0014] Preferably, the magnifying lens is mounted on the upper end of the mounting plate, and the magnifying lens is positioned directly above the perforation.

[0015] The beneficial effects of this utility model are as follows: This in-line pattern magnification optical structure for pattern beam lights achieves the effect of instantly changing the pattern projection magnification without moving the focusing lens module by adding a magnifying lens module that can precisely cut in and out of the original optical path. It has the advantages of fast switching speed, compact structure and high imaging quality. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example 1

[0023] Reference Figures 1-3 As shown, a cut-in pattern magnification optical structure for a pattern beam lamp includes a light source 1, a pattern disk 2 mounted above the light source 1, a magnifying lens module 3 mounted above the pattern disk 2, a focusing lens module 4 mounted above the magnifying lens module 3, and a light-emitting lens module 5 mounted above the focusing lens module 4. The magnifying lens module 3 includes a driving component 6, a transmission mechanism 7 fixedly connected to the output end of the driving component 6, a bracket 8 fixedly connected to one end of the transmission mechanism 7, and a magnifying lens 9 fixedly mounted on the upper end of the bracket 8.

[0024] In this embodiment, the driving component 6 drives the transmission mechanism 7 to move, the transmission mechanism 7 controls the movement of the bracket 8, and the bracket 8 drives the magnifying lens 9 to move, thereby causing the magnifying lens 9 to have two working positions: the first position (cut-in position, such as...) Figure 1 The magnifying lens 9 is precisely moved to the center of the optical axis, located between the pattern disk 2 and the focusing lens module 4, forming a new composite optical system with the focusing lens module 4, thus magnifying the projected pattern; the second position (cutout position as shown) Figure 2 The magnifying lens 9 is completely removed from the optical path, and the beam passes directly through the focusing lens module 4 and the output lens module 5, with the lamp operating in conventional beam lamp mode. By adding a magnifying lens module 3 that can be precisely inserted and removed into the original optical path, the pattern projection magnification can be changed instantly without moving the focusing lens module 4, which has the advantages of fast switching speed, compact structure, and high imaging quality.

[0025] Furthermore, the focusing lens module 4 can move back and forth along the optical axis to compensate for the image plane changes caused by the introduction of the magnifying lens group when the magnifying lens group is in the cut-in position, thereby obtaining a clear magnified pattern; when the magnifying lens group is in the cut-out position, it performs conventional pattern focusing.

[0026] Furthermore, the transmission mechanism 7 is a linkage mechanism. The forward and reverse rotation of the drive component 6 drives the linkage mechanism to move, thereby driving the bracket 8, which mounts the magnifying lens 9, to complete an approximately linear "cut-in" and "cut-out" action.

[0027] Furthermore, the magnifying lens 9 is a biconvex lens or a plano-convex lens, or the magnifying lens 9 is a cemented lens group, consisting of at least two lenses cemented together, used to better correct aberrations and improve the edge sharpness of the magnified pattern. Example 2

[0028] Reference Figures 4-5 As shown, a cut-in pattern magnifying optical structure for a pattern beam lamp is disclosed. A mounting groove 10 is fixedly formed on the disc of a bracket 8, and a through hole 11 is fixedly formed at the lower end of the mounting groove 10. Multiple sets of screw holes 13 are formed on the outer side of the through hole 11, and these screw holes 13 are evenly spaced on the mounting groove 10. A mounting plate 12 is mounted on the upper end of the mounting groove 10, and multiple sets of fixing bolts 14 are installed on the mounting plate 12. These fixing bolts 14 are threaded into the screw holes 13. A magnifying lens 9 is mounted on the upper end of the mounting plate 12, positioned directly above the through hole 11. When the magnifying lens 9 needs to be replaced, the fixing bolts 14 are rotated to disengage from the screw holes 13, allowing the mounting plate 12 to be removed from the mounting groove 10. This facilitates the replacement of different magnifying lenses 9, making the process convenient.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
