Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to an adjustable focal length spotlight optical module. Background Technology

[0002] Spotlights are a typical modern lighting device without a main light or fixed scale. They can create indoor lighting atmosphere. As the core component of the lighting system, the focal length adjustment capability of the spotlight optical module directly affects the flexibility of the illumination range and light spot quality.

[0003] However, traditional spotlight optical modules generally suffer from fixed focal length or limited adjustment range. Specifically, the fixed focal length design makes the spotlight unable to adapt to the lighting needs of different scenarios. For example, when illuminating at close range, it is easy to form a bright spot or blurry edges, while when illuminating at long distance, the light intensity is insufficient. On the other hand, the few products with focusing function mostly rely on gear meshing or screw rotation for adjustment, which is not convenient enough. At the same time, it is not possible to easily disassemble and assemble the lamp cover and the lamp housing.

[0004] Therefore, in order to further improve the focal length adjustment and assembly convenience of existing spotlights, we propose an adjustable focal length spotlight optical module. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing an adjustable focal length spotlight optical module.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design an adjustable focus spotlight optical module, including:

[0008] Lamp housing with installed light panel;

[0009] The lamp housing has a sliding part at the front end, and a lamp cover is fitted and slidably attached to the outside of the sliding part. A lens is installed inside the lamp cover.

[0010] The lamp housing has a sliding groove on the outer periphery of the sliding part, and a docking component is provided inside the sliding groove. The inner side of the lamp cover has a snap-fit ​​structure that can be detachably connected to the docking component.

[0011] Furthermore, the docking assembly includes a slip ring slidably connected inside the lamp housing, an elastic portion defined by a U-shaped groove on the outer side of the slip ring, a docking post fixedly installed on the outer side of the elastic portion, the docking post slidably connected inside the slide groove, and multiple locking ports connected to the side of the slide groove.

[0012] Furthermore, the buckle structure includes a guide groove formed in the inner ring of the lampshade and a snap hole;

[0013] The guide groove is inclined toward the outside of the lampshade, and the locking hole is connected to the tail end of the guide groove.

[0014] Furthermore, a first sealing ring is fitted on the outer side of the sliding part, the outer side of the first sealing ring abuts against the inner ring of the lamp cover, and a second sealing ring is formed at both ends of the slip ring.

[0015] Furthermore, the lamp panel is fixedly installed inside the lamp housing by a support column, the slip ring is sleeved on the outside of the lamp panel, and a reflector is also fixedly installed at the front end of the lamp panel.

[0016] Furthermore, the lampshade has a stepped section inside, the lens is placed on the stepped section, and a pressure ring that abuts against the lens is threaded to the front end of the stepped section.

[0017] The adjustable focal length spotlight optical module proposed in this utility model has the following advantages: By adopting a sliding structure design for the lampshade and lamp housing, the focal length of the illuminated lampshade can be adjusted by changing the distance between the lens and the lamp plate. This allows for adaptive adjustment of the focal length during the installation of the spotlight, thereby improving the optical effect.

[0024] 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.

[0025] Reference Figure 1-5 As an embodiment of this utility model, it discloses an adjustable focal length spotlight optical module. Specifically, the optical module includes a lamp housing 1 on which a lamp board 10 is mounted. Of course, in this embodiment, the lamp board 10 includes a circuit board and lamp beads electrically connected to the circuit board. The circuit board is connected to a power supply to light up the lamp beads. This structure is a conventional method for those skilled in the art and will not be described in detail here.

[0026] In addition, in this embodiment, the lamp plate 10 is fixedly installed inside the lamp housing 1 by the support column 14. The support column 14 can be set in multiple ways. The support column 14 is formed on the inner side of the lamp housing 1. The lamp plate 10 can be connected to the support column 14 by fasteners such as bolts.

[0027] A sliding part 11 is provided at the front end of the lamp housing 1. A lamp cover 2 is sleeved and slidably mounted on the outside of the sliding part 11. A lens 3 is installed inside the lamp cover 2. Specifically, the lens 3 is set as a convex mirror. The lamp cover 2 is slidably connected to the lamp cover. When the distance between the lens 3 and the lamp plate 10 changes, the focus of the lamp cover being illuminated can be adjusted.

[0028] In this embodiment, the lamp housing 1 has a groove 12 on the outer periphery of the sliding part 11. Preferably, there are two grooves 12 to improve the connection stability with the lamp cover 2. The groove 12 is provided with a docking component 4, and the inner side of the lamp cover 2 has a buckle structure 5 that is detachably connected to the docking component 4.

[0029] In this invention, by adopting a sliding structure design for the lampshade 2 and the lamp housing 1, the focal length of the illuminated lampshade can be adjusted by changing the distance between the lens 3 and the lamp plate 10. This allows for adaptive adjustment of the focal length during the installation of the spotlight, thereby improving the optical effect. In addition, the lampshade 2 and the lamp housing 1 are detachably connected by a docking component 4 and a snap-fit ​​structure 5, which greatly improves the convenience of operation during actual assembly and subsequent maintenance, and optimizes the applicability of the spotlight.

[0030] In some embodiments, the docking assembly 4 of the present invention includes a slip ring 41 slidably connected inside the lamp housing 1, an elastic portion 42 defined by a U-shaped groove on the outer side of the slip ring 41, a docking post 43 fixedly installed on the outer side of the elastic portion 42, the docking post 43 slidably connected inside the slide groove 12, and a plurality of locking holes 45 connected to the side of the slide groove 12.

[0031] In this embodiment, three locking slots 45 are provided, forming an E-shaped structure with the sliding groove 12. The locking slots 45 are used to lock the docking post 43. When adjusting the focus, the lampshade 2 can be slid back and forth to adjust the focus, and then the lampshade 2 can be rotated to make the docking post 43 slide into the locking slot 45, thus forming a back-and-forth sliding lock. In this embodiment, the design of three locking slots 45 can form three-position locking. Of course, in other embodiments, those skilled in the art can adjust the number of locking slots 45 according to actual needs, which will not be elaborated here.

[0032] Of course, the U-shaped groove described in this embodiment can also be adapted to be two, that is, two elastic parts 42 are provided. The slip ring 41 described in this embodiment is a plastic part, so that the elastic part 42 can achieve relative displacement movement by means of its elasticity. In addition, the outer diameter of the slip ring 41 described in this embodiment is the same as the inner diameter of the front end of the lamp housing 1 to ensure the stability of sliding.

[0033] Specifically, in this embodiment, a slip ring 41 with a docking post 43 is used. When the docking post 43 slides inside the slide groove 12, the slip ring 41 will also move synchronously. In addition, when the elastic part 42 is pressed, the elastic part 42 moves downward, which can drive the docking post 43 to move downward.

[0034] Based on the above embodiments, the buckle structure 5 in this utility model includes a guide groove 51 formed in the inner ring of the lampshade 2 and a snap hole 52;

[0035] The guide groove 51 is inclined toward the outside of the lampshade 2, and the card hole 52 is connected to the tail end of the guide groove 51.

[0036] During the actual connection, first insert the lampshade 2 into the front end of the lamp housing 1. Then, insert the guide groove 51 into the docking post 43. The guide groove 51 will deform and move against the docking post 43. As the lampshade 2 continues to be inserted, the docking post 43 is inserted into the inside of the locking hole 52. At this time, the connection between the docking post 43 and the lampshade 2 is completed. The user can adjust the focus by sliding the lampshade 2. At the same time, the sliding of the docking post 43 can be used to guide the sliding of the lampshade 2 and lock and limit its movement.

[0037] Of course, when it is necessary to disassemble the lampshade 2, the lampshade 2 can be pulled out to its longest position first. At this time, use a tool to press against the elastic part 42 to deform it until the docking post 43 separates from the inside of the locking hole 52. This completes the disassembly of the lampshade 2 and the lamp housing 1. Of course, those skilled in the art know that the locking method of the docking post 43 and the locking hole 52 is a conventional method used by those skilled in the art. The shape of the docking post 43 and the locking hole 52 can be achieved by adopting arc-shaped, V-shaped or other structural designs. No specific restrictions are placed on their specific shapes here.

[0038] Furthermore, in this embodiment, a first sealing ring 13 is also sleeved on the outer side of the sliding part 11. The outer side of the first sealing ring 13 abuts against the inner ring of the lampshade 2. In this embodiment, the first sealing ring 13 can not only improve the dustproof effect between the lampshade 2 and the lamp housing 1, but also improve the adjustment reliability of the lampshade 2 by the damping force generated between the first sealing ring 13 and the lamp housing 1. The two ends of the slip ring 41 are also formed with second sealing rings 44. Of course, the second sealing rings 44 abut against the inner side of the lamp housing 1.

[0039] In some embodiments, the slip ring 41 of the present invention is sleeved on the outside of the lamp plate 10. The sleeved structure design can avoid the slip ring 41 from interfering with the lamp plate 10. A reflector cup 15 is also fixedly installed at the front end of the lamp plate 10.

[0040] It should be noted that the lampshade 2 in this embodiment has a stepped portion 21 inside, and the lens 3 is placed on the stepped portion 21. A pressure ring 22 that abuts against the lens 3 is threaded to the front end of the stepped portion 21. That is, in this embodiment, the pressure ring 22 is used to press and abut against the lens 3. When it is necessary to disassemble and replace the lens 3, the pressure ring 22 can be rotated and disassembled first, and then the lens 3 can be removed. The operation is simple and convenient.

[0041] 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.
